Rhazya stricta is an important medicinal plant species distributed all over the Warcha salt mine in Pakistan. Analysis of proximate composition and metals is a commendable job to assess the suitability of the exploitation of medicinal plants on a large scale by ethnic communities. The proximate analyses (moisture, fiber, ash, crude fats, proteins and carbohydrates) of all the samples collected from five different sites (Table 1) were carried out. Moreover, different inorganic elements in the samples were also determined. The maximum and the minimum moisture content in Rhazya stricta was observed at Site 4 (31.21%) and Site 2 (29.14%), respectively. The maximum and the minimum ash concentrations were recorded in the populations collected from Site 2 (7.48%) and Site 5 (6.25%), respectively. The maximum fat content was found in the Site 3 (3.91%) population, whereas the minimum contents of crude fiber were observed in the population from Site 2 (12.2%). The maximum concentration of crude protein was observed in the plants from Site 5 (9.93%), whereas the minimum contents of carbohydrates were observed in the plants from Site 2 (48.4%). Essential and nonessential elements like potassium (K), magnesium (Mg), iron (Fe), nickel (Ni), chromium (Cr), cadmium (Cd), cobalt (Co), copper (Cu), manganese (Mn), and zinc (Zn) were analyzed in the roots, stem and leaves of Rhazya stricta. The maximum K content (6836.886 mg/kg) was found in the roots of plants collected from Site 5 and the minimum in the leaves (5528.795 mg/kg) collected from Site 3. The highest concentration of magnesium was found in the roots of plants from Site 3 (2414.46 mg/kg), whereas the lowest concentration of iron was recorded in the leaves of Site 4 (31.45 mg/kg) plants. The maximum and the minimum concentrations of cobalt were detected in the roots of plants from Site 1 (0.320 mg/kg) and in the leaves of plants from Site 4 (0.135 mg/kg), respectively. The minimum concentration of leaf cadmium was recorded in plant population from Site 4, whereas in the same population the maximum level of root nickel was recorded. The highest concentration of copper was observed in the stem of plant population from Site 2 (0.297 mg/kg). The concentrations of most of the elements appraised in the present study are well below the overall permissible limits of these elements in medicinal plants determined by WHO, so this plant from the Warcha mine can be utilized without harm by herbal practitioners and pharmaceutical industry.

Heavy metal pollution in soil, forage, and animals is serious concern nowadays. Current research was conducted in Sargodha to find out the relationship of animals related to the forages and soil pollution. Three sites were selected with three different treatments; site I irrigated with ground water, site II irrigated with the canal water, and site III irrigated with the wastewater. Samples of soil, forage, and animals (blood, hair, feces) were collected from selected sites and were analyzed for metal analysis using atomic absorption spectroscopy. Results indicated that Zn in soil ranged from 24.12 to 37.39 mg/kg; forage, 31.98-44.47 mg/kg; blood of animals, 1.49-2.72 mg/L; hair of animals, 1.37-2.41 mg/kg; and feces of animals, 1.06-2.97 mg/kg. The concentration of zinc in soil and forage was less than permissible limit, but concentration in blood of animals was greater than critical limit suggesting the presence of metal. Bio-concentration factor indicated that metal was accumulated in forages growing at irrigated site. HRI concentration (2.024 mg/kg/day) suggests the accumulation of zinc in animal tissues. Pollution load index and enrichment factor were within the range.

Grazing animals act as a bioindicator to study the heavy metal status in the pasture lands because excessive amount of toxic metals in the animal diet either disturb their normal activity or deposit the contaminants into their tissues. The aim of this study was to appraise the chromium status in soil and pasture crops with respect to the nutritional requirement of grazing animals. Three different sites were selected to collect soil, forages, and animal samples from District Jhang. All the samples were processed through atomic absorption spectrophotometer to analyze the chromium concentration in them. Chromium concentration was varied as 0.703-4.20 mg/kg in soil, 0.45-2.85 mg/kg in forages, and 0.588-2.37 mg/kg in all collected animal samples. Both the soil and forage samples displayed the maximum chromium concentration in the Capparis decidua, whereas animal samples revealed maximum concentration in animal blood. Results of pollution load index (0.078 to 0.463 mg/kg) exhibited that all the sample values are less than unity while enrichment factor (1.57-8.25mg/kg) showed that significant level of chromium is enriched in these sites. The maximum value of daily intake (0.0007-0.0055mg/kg/day) and health risk index (0.0004-0.00370055mg/kg/day) was observed in the buffalo that feed on the Capparis decidua. Bio-concentration factor (0.398-2.09mg/kg) value was the maximum in the Medicago sativa. It is concluded that all the animal samples showed chromium concentration beyond their standards. Thus, proper measures should be taken to reduce the metal contamination in these areas that ultimately lessen the availability of toxic metals to grazing animals.

Proximate and nutritional concentrations of some vegetables irrigated with different types of water were determined in present study. Allium fistulosum showed highest concentrations of N and P at site3 and site1, respectively. Highest ash concentration in Trigonella foenum-graecum demonstrated high mineral concentration of this vegetable. The crude protein contents ranged from 15.38% to 26.19% and crude fiber contents ranged from 12.81% to 16.73% in all vegetables. The tannins and saponins contents showed significant (P

The aim of this study was to access the Mn contamination in soil, forages, and animals. Heavy metal pollution is a matter of prime significance in natural environment. Through food chain, toxicity of heavy metals and their bioaccumulation potential are transferred into humans. Higher concentrations of metallic compounds are toxic to living organisms but these are essential to maintain body metabolism. Intake of food crops polluted with heavy metals is chief food chain channel for human exposure. Animals are exposed to heavy metal stress by the intake of richly contaminated food crops; those are chief part of food chain. Samples of soil, plant, animal blood, hair, and feces were collected to find contamination through wet digestion process in lab and metal analysis. Different forages were collected to study Mn content that was our major concern in this study. The present findings also emphasized on the assessment of bio-concentration factor (BCF). Other significant indices of mobility and pollution of metal were also calculated, i.e. pollution load index (PLI), daily intake of metal (DIM), health risk index (HRI), and enrichment factor (EF). The experimentation result showed different concentrations of metal in different seasons. The Mn concentration in forages was 20.01-28.29 mg/kg and in soil was 5.27-8.90 mg/kg. Soil samples showed higher level of (PLI) Pollution load index. Bio-concentration of MN was 2.59-4.21 mg/kg. It can be concluded that regular monitoring of the metal is essential to evaluate the contamination status. Mn contents were in the safe limits in soil and plants; however, its toxic level was observed in animals.

Heavy metals are considered as most important contaminations due to industrialization of countries and an influence on its existence in soil, plant and milk. A study was carried out to check manganese content in soil, forage and milk at three sites of city Jhang, Punjab, Pakistan. All samples (milk, soil, water, fodder plants and ground water) were analyzed for manganese by Atomic Absorption Spectrophotometer. Different health indices were also studied to check Mn flow in food chain. Level of Mn in samples was found within acceptable limits. Manganese level was higher in soil samples collected from Site-III than other sites. Manganese showed higher value (2.595 to 10.402 mg/kg) in soil than other samples. Fodders were found to accumulate manganese from 0.008 to 0.022 mg/kg. Manganese concentration was found to be 0.1482 to 1.241 mg/L, 0.164 to 0.9708 mg/L in water and milk, respectively. BCF and PLI values for manganese were also found to be less than 1. Estimated daily intake (EDI) and THQ of manganese are found within permissible limits in milk of cows feeding on fodders irrigated with wastewater and ground water. So, use of wastewater for irrigation purpose should be properly checked due to possible toxic effects.

The recent research was performed to investigate the toxicity of As and Cd in suburban area of Sargodha, Punjab, Pakistan. Water, soil and forage samples were collected for this purpose in summer and winter season and analysis was done via wet digestion to determine the concentration of selected heavy metals. The mean concentration of As and Cd in water was found above the permissible maximum limit. Mean concentration of Cd in soil and forages was lower than the allowed limit whereas As which was higher than the PML in forages. So, continuous use of domestic wastewater for irrigation purpose should be avoided in order to secure the area from any hazard in near future.

This investigation was done for the assurance of potassium amassing in four assortments of maize (grains, shoot and root), soil, and water and in seven tissues of chickens (kidney, liver, heart, bone, gizzard, breast meat). The analysis of variance showed significant differences for potassium concentration in water in all sources of water; however, the season and variety significantly influenced the quantity of potassium in cereals. The corn varieties MMRI, Sadaf, and Pearl behaved differently when treated with water from various sources. Water taken from sewage had a higher concentration of potassium compared to canal and groundwater that is why the maize plants irrigated with this water had a higher grouping. Data regarding potassium concentration in different body parts of chicken showed that season and treatment have a significant effect on the potassium concentration in chicken organs. The variety was non-significant for the potassium concentration only in the bone. Season × Variety interaction was only significant in blood, meat heart, and gizzard. Season × Treatment and Variety × Treatment interactions were significant in the heart, kidney, and gizzard. The potassium contents were higher in the chicken body parts that were reared on grains irrigated with sewage water as compared to other groups. The potassium contents were higher in the chicken meat (96.23 ± 0.00) reared on grains of the Pearl variety raised with the sewage water. In a nutshell, the irrigation of grains with sewage water led to accumulation of nutrients greater than those irrigated with ground or canal water.

The instant endeavor was undertaken for determination of lead (Pb) in water, soil, forage, and cow's blood domesticated in contaminated area of heavy automobiles' exhaust in Sahiwal town of District Sargodha, Pakistan. Water samples showed that the concentration of Pb ranged from 1.14 to 0.44 mg kg-1 at all sites. It was maximum at site 5 and minimum at site 2. Soil samples showed the concentration of Pb at all sites ranged from 1.58 to 0.279 mg kg-1. It was maximum in soil where Avena sativa was grown at site 5 and was found minimum in soil where Zea mays was grown at site 2. While among samples of forage, the concentration of Pb ranges from 0.048 to 2.002 mg kg-1. The highest Pb amount was found in Brassica campestris at site 1 and the minimum was recorded in Trifolium alexandrinum at site 2. Finally, the blood samples of cow depicted that concentration of Pb ranged from 4.468 to 0.217 mg kg-1. It was the maximum at site 1 and the minimum at site 3. It is recommended that such study should be conducted in other districts for public awareness.

In current work, we examined the absorption of metal Copper in generally grown food crops (Maize & Millet), cultivated in the waste water irrigated different Districts of Punjab, Pakistan. Analyzed samples of Water, Soil, shoot and grain were processed through atomic absorption spectrometric method. Our findings of Copper in water and Shoot were highest for Millet of Sargodha, irrigated with wastewater (1.69 mg/kg and 1.43 mg/kg respectively). In soil and grain samples maximum absorption of Cu was obtained in the waste water irrigated Maize (Sargodha) and Millet (Sheikhupura). Overall, Cu level was within the acceptable parameters set by FAO/WHO (2001). In this study, we also find out different indices such as Enrichment factor, Translocation factor, Pollution Load Index, Bio-concentration factor, Daily intake of metal and Health Risk Index. The study determined that frequently intake of waste watered forages in experimenting zone may carry possible health uncertainties in inhabitants.

Due to increasing population and increasing number of automobiles the fodder samples were collected from Khushab District along the roadside to examine the heavy metal contamination. It was a serious issue because animals consume these contaminated fodders and then they enters the food chain where they cause toxicity. Five fodder plants Pennisetum glaucum, Trifolium alexandrinum, Saccharum officinarum, Zea mays and Brassica compestris were selected for sampling. The sampling of selected fodder plants and their soil was done during November which was the driest season of Khushab city and the dust and smoke was present on the fodder plants. The samples were air and oven dried. Then subjected to digestion. Acid digestion was done with Nitric acid (HNO3), Hydrogen peroxide (H2O2) and Hydrogen chloride (HCL). The samples become transparent and the heavy metal analysis of both soil and fodder samples was done through Atomic absorption spectrophotometer (AASP). Lead and zinc heavy metals were analyzed. The pollution load index was lower than 1 which indicates that there was low concentration of metal in soil of the collected samples of the current study. It was obtained that the soil was less polluted. The daily intake of metals was lower than 1 that concluded that they were at safe limit during consumption. The present study showed the enrichment concentration of metals greater than 1 it means these metals were present in both soil and fodder samples growing near roadside.

The present investigation aimed to assess the metal contents (Fe, Zn, Cd, Co) in wheat (Triticum aestivum) crop by selecting variety (Fareed-06) which was grown in the municipal solid waste amended soil. Metal quantification in segregated plant parts of wheat was done with the help of atomic absorption spectrophotometer. Result depicted the range of metals in plant samples to be 4.03 to 7.82 for Zn, 2.38 to 3.06 for Co, 1.7 to 2.91 for Cd and 66.62 to 81.66 mg/kg for Fe. In wheat grains, the heavy metal concentrations ranged from: 0.79 to 2.03 for Zn, 1.21 to 1.71 for Co, 0.87 to 1.04 for Cd and 10.41 to 21.91 mg/kg for Fe. The concentration of Cd in grains exceeded the limit set by FAO/WHO. The transfer factor and bioconcentration factor was less than 1 for all metals. The pollution load index and enrichment factor for Cd was highest among all metals. Health risk index for Cd in all treatments was ]1 indicating Cd contamination in wheat grains and various health hazards to human. So, the municipal solid waste should be treated properly before its application on agricultural field to reduce the health hazards in human.

The use of wastewater in irrigation weakens the beneficial properties of the soil and leads to a threat to food safety standards. The present research was designed to explore the cobalt toxicity associated with the ingestion of wastewater irrigated wheat. Wheat plants of five different varieties were collected from 7 different sites of Punjab, Pakistan, which were irrigated with three different sources of water. The sampling was done in two cropping years. The cobalt values in water, soil and wheat samples (root, shoot, grain) ranged from 0.46 to 1.24 mg/l, 0.15 to 1.20, 0.29 to 1.30, 0.08 to 0.76 and 0.12 to 0.57 mg/kg, respectively. All the water samples showed high cobalt concentration than the maximum permissible value. However, all the soil and wheat plant samples were found within the maximum allowable range. The high cobalt concentration in irrigating water showed that the continuous usage of such type of water may lead to cobalt toxicity in living organisms with the passage of time and may results in severe health risks.

Heavy metal concentration in sewage water irrigation of fodders, milk, and soil was studied. It was a serious issue because excess of sewage water is used for irrigating crops and due to excessive use of waste-water heavy metals build up in plants and when animals consume these plants metals transfer to their bodies and milk causes different problems. Six samples were collected Trifolium alexandrinum, Avena sativa, Zea mays, Pennisetum glaucum, Sorghum bicolor, Brassica campestris from five sites. All the samples were digested by wet digestion method. After digestion a clear transparent solution of all samples was obtained which was analyzed in atomic absorption spectrophotometer. Different indices were applied including bio concentration factor, daily intake of metals, health risk index, enrichment factor, pollution lad index, correlations of fodders, soil and milk was done. Pollution load index of current study was less than 1 which indicates that soil was less polluted. Health risk for Cd was present higher than 1 which was an indication of risk to health of animals in eating Cd contaminated fodders. Daily intake of metal was lower than 1 it showed there was no risk in consuming fodders to health of animals. In water samples level of Cd was higher above permissible limit. Cd mean concentration was higher in milk than permissible limit which showed that animals graze more contaminated fodder in open areas and drink waste-water that�s why metals accumulate in their tissues and milk causing toxicity.

This study investigated the changes in the enzymatic and biochemical profiles of lactating, non-lactating, and young buffaloes during different sampling. In the present research thirty buffaloes (Nili-Ravi) were selected and divided into three categories lactating, non-lactating, and young. Four samplings were performed in different seasons (summer, autumn, winter, and spring), and 10 blood serum samples were collected from each category of Nili-Ravi buffaloes during each sampling period. Higher glucose, urea, creatinine, and mycotoxins (AFB1, ZEA, OTA) values were found during summer sampling season, higher SGPT (ALT) and SGOT (AST) values were found during the autumn season, higher cholesterol, alkaline phosphatase and uric acid values were found during the winter season.

Like animals plants required nutrients for their growth and existence. Cobalt is also important element for plant and animal growth, however higher levels of Co might have toxic potential. The study was aimed to investigate Co level in samples of forages, soil, and blood plasma of sheep and goat in Bhakkar, Mianwali and Sargodha district. The results showed that district Mianwali excelled in level of Co as compared to Bhakkar and Sargodha. The factors such as bio-concentration factor and pollution load index explained the movement of cobalt along the soil-plant-animal continuum.

The study was carried out to evaluate the health risks associated with accumulation of cadmium in the different genotypes of wheat, grown in agricultural regions of Punjab, Pakistan. Five genotypes irrigated with three varied water sources were selected randomly from each region. Among all sources of water, types of soil, and grain samples, the cadmium (Cd) quantities were found (2.24-2.82 mg/L, 1.75-4.16 mg/kg, 0.86-1.90, respectively), exceeding the maximum permissible limits (0.01 mg/L, 1.1 mg/kg, 0.2 mg/kg, respectively) described by FAO/WHO. The pollution load index (PLI) exhibited by all of the samples was higher than 1.00, the permissible limit; however, other factors including bioaccumulation, translocation, bio-concentration, daily intake, and enrichment values of Cd were less than 1.00. Moreover, the health risk index for cadmium in all types of wheat grain samples was less than 1.00. The study concluded that the continuous use of wastewater resources may lead to the accumulation of cadmium in the vital body organs that may cause severe health hazards.

The article is focused on estimation of Zinc in the roadside forages, and blood of buffaloes feeding on these forages. This study was carried out in Sargodha during December 2015 to January 2016 (winter) and May 2016 to June 2016 (summer). Five road sites (Mateela, Faisalabad roadside, Shaheenabad roadside, Bhalwal roadside and 50 chak) were selected from sampling of forages, soil and buffalo blood sample. Heavy metal analysis of all digested samples was done with atomic absorption spectrophotometer. Analysis of variance and correlation was done with two way ANOVA. This study regarding the accumulation of zinc in forages, soil and the buffalo blood would help the authorities to exactly determine the agents which are responsible for increasing pollution in the environment.

The article is focused on concentration of cadmium in maize and millet collected in 2018-2019 from different district (Sargodha, Faisalabad, Sheikhupura, Lahore and Kasur) of Punjab under different irrigation sources Canal and wastewater. The values of Bioconcentration factor, Translocation factor, Pollution load index, Daily intake of metal, Health Risk Index and Enrichment factor were studied to evaluate the effect of heavy metal accumulation on grains quality and human health. Most of the metals observed in wastewater were present in high amount. Cd concentration increased considerably under wastewater irrigation in soil (1.06 mg/kg) and grains (1.05 mg/kg). Cd showed highest bioconcentration (3.82 mg/kg) in canal water. Wastewater irrigated soil exhibited the maximum Pollution Load Index (PLI) values as compared to control treatment. Under the influence of wastewater irrigation, Cd concentration increased considerably in soil and grains. The purpose of study is the labeling of Maize and Millets species of the area according to their toxicity/desirability for use as human food and fodder.

The research was aimed to determine seasonal effects on trace metals levels in soil, forages and blood plasma of animals. The mean cadmium, chromium and copper values in soil samples in different sampling seasons were ranged from 6.97 to 4.10, 0.060 to 0.72 and 3.54to 4.08 mg/kg, respectively, while, in forage samples were between 0.671-0.697, 1.57-2.22 and 6.75-7.06 mg/kg, respectively. Higher Cd, Cr and Cu concentrations were observed in blood plasma of young buffaloes during summer season, in dry buffaloes during spring season and in young buffaloes during autumn season, while lower Cd, Cr and Cu contents were noticed in blood plasma of lactating buffaloes in summer season. The highest bio-concentration factor value from soil to forage was determined for Cr while from forage to blood plasma of buffaloes was detected for Cd. The Cd, Cr and Cu correlation of soil with blood plasma were positive for all samples.

Pollution caused by municipal solid waste (MSW) is becoming a serious threat to the environment. Composting may be an effective way to speed up the decomposition of biodegradable components in MSW, resulting in compost that can be utilized as an organic fertilizer. The pot experiments were carried out with different soil-MSW mixtures (100:0, 75:25, 50:50, and 25:75; w/w) to determine the impact of MSW on the bioconcentration of Cd in commonly consumed plants of Sargodha. The possible health risks were evaluated by applying pollution indices, such as the pollution load index, bioconcentration factor, enrichment factor, and health risk index. The pollution load index was higher than 1 in 75% MSW-amended soil. However, the concentration of Cd was found to be below the permissible limits in all studied vegetables, with a range of 0.019-0.106 mg/kg. In the study, serum samples from different volunteers living in four sites in Sargodha were also collected and analyzed. For vegetable crops, the health risk index (HRI) was less than one. It is concluded that the concentration of Cd was increased by increasing the fraction of MSW. Although the metal contents in the soil treated with MSW were not high enough to categorize the soil as polluted, these findings show that the reuse of MSW can serve as an alternative to mineral fertilizers. However, the presence of Cd in MSW can have a direct impact on soil fertility and, if biomagnified, on crop production and human health.

The cheapest way of disposal of wastewater is its use in agriculture. The pressure in using fresh water resources may be alleviated by the domestic wastewater in agriculture. Wastewater holds significant quantity of plant nutrients like N, P, Ca, K, Co, Zn, and Mn. Therefore, it increases the crop yield. Triticum aestivum is the staple food crop for Pakistan, where it is an important caloric source. It is grown successfully in rain fed areas of the country as well as in irrigated areas with minimum water without losing its production potential. In this study, cadmium (Cd), nickel (Ni), iron (Fe), manganese (Mn), copper (Cu), chromium (Cr), zinc (Zn), and cobalt (Co) were evaluated; the effect of wastewater was studied on wheat variety (Punjab-2011) by applying different treatments of wastewater. In the comparison between five different treatments, in soil, Fe was the highest. The chromium in the current findings exceeded the permissible limit (0.03 mg/kg) in wheat grains. The reason of high Cr concentration might be due to the increased usage of wastewater for long periods. The level of pollution or the factor of contamination was the lowest for Zn and was highest for Cd in all treatments. Chromium has the lowest value of health risk index while Cd has the highest value in all treatments, indicating that exposed population is unlikely to experience obvious adverse effects on utilization of these contaminated grains of wheat.

The trace metal pollution in the environment is a highly concerned issue in these days. One of the important causes of trace metal pollution is the exhaust gases released from the vehicles on the roads. These dangerous gases pose life-threatening effects on the forage plants grown along the roadside as these plants are at direct risk to these trace metals. The aims of the present study were to determine the cobalt (Co) concentrations in soil, forages, and blood plasma of the buffaloes and to evaluate the Co deficiencies and toxicities in these samples. All samples were collected from six sites (Faisalabad roadside, Bhalwal roadside, Shaheenabad roadside, Mateela roadside, 50 Chak roadside, and Dera Saudi-control) of Sargodha city. The Co concentrations in these samples were determined by atomic absorption spectrophotometer (AA-6300 Shimadzu Japan). In soil samples, Co level ranged from 1.958 to 3.457 mg/kg in the six sampling sites. The highest Co level was observed at site 6 and the lowest at site 2. In forage samples, Co level ranged from 0.770 to 2.309 mg/kg in the six sampling sites. The highest Co level was observed at site 3 and the lowest at site 2. In blood plasma samples, Co level ranged from 2.644 to 4.927 mg/kg in the six sampling sites. The highest Co level was observed at site 1 and the lowest at site 3. The results showed higher Co values in the samples collected from the site IV while the bioconcentration factor for forage-soil was found highest in the samples collected from Site III. On the other hand, a correlation was found positively significant when soil and forage were correlated, and it was found negatively significant when blood and forage were correlated.

Heavy metal pollution has thoroughly worldwide apprehensions due to the instantaneous growth of industries. Farming regions are irrigated mainly with wastewater which contains both municipal and industrial emancipations. Therefore, three sites irrigated with ground, canal and municipal-wastewater in the District Jhang were selected to determine the zinc accumulation and its transfer in the soil, plant and animal food-chain. Soil, forage and animal samples of cow, buffalo and sheep were selected from each site. Various pollution indices were also measured to assess the zinc exposure to grazing animals. Zinc concentration was ranged as 18.85-35.59mg/kg in the soil, 26.42-42.67 mg/kg in the forage and 0.982-2.85mg/kg in the animal samples. Investigated zinc concentration in soil and forages was found to be within the recommended WHO/FAO limits but blood samples exceeding the standards of NRC (2007). Maximum level of pollution load index (0.427-0.805mg/kg) and enrichment factor (0.373-0.894 mg/kg) for zinc was noticed upon waste water irrigation. Daily intake (0.039 to 0.082 mg/kg/day) and health risk index (0.130 to 0.275 mg/kg/day) of zinc metal was higher in the buffaloes that feed on waste water irrigated forages. Bio-concentration factor (0.840 to 2.01mg/kg) for soil-forage was >1 represented that these plants accumulated the zinc concentration into their tissues and raised health issues in grazing animals on consumption of waste water contaminated forages. Overall findings of this study, suggested that animal herds should be monitored periodically to devise preventive measures regarding the toxic level of heavy metals availability to livestock.

The aim of study was access the cobalt and lead contamination in soil, forages and animals. Heavy metal pollution is a matter of prime significance in natural environment. Through food chain toxicity of heavy metals and their bioaccumulation potential are transferred into humans .Higher concentrations of metallic compounds are toxic to living organisms but these are essential to maintain body metabolism. Intake of food crops polluted with heavy metals is chief food chain channel for human exposure. Animals are exposed to heavy metal stress by the intake of richly contaminated food crops those are chief part of food chain. We collected samples of soil, plant, animal blood, hair and faeces to find contamination through wet digestion process in lab and metal analysis. Different forages were collected to study Zn amount in forages whilst soil and animals in Mianwali Pakistan. The health risk index (HRI) calculation was our major concern in this study. Our present findings also emphasized on the assessment of bio-concentration factor (BCF). We also calculated other significant indices i.e. Pollution load index (PLI), daily intake of metal (DIM), Health Risk Index (HRI) and Enrichment factor (EF). While the experimentation result showed different concentrations of metal in different seasons. When the Zn concentration in forages was (32.59-42.17mg/kg) and in soil (21.82-35.09 mg/kg). Soil samples showed higher level of (PLI) Pollution load index. Bio-concentration of zinc was (1.03-1.57mg/kg). It can be concluded as regular monitoring of the level metal is essential evaluate the contamination status.

Over past several years pollution in industrialized areas is the most attention seeking issue. Higher level of heavy metals especially cadmium is accumulated in atmosphere evolved from smoke of automobiles. Living system present around the contaminated areas accumulate heavy metals in their bodies. Heavy metals have been accumulated in soil, water, forages and animals so study was conducted in industrialized area Faisalabad to evaluate the possible risk. Three sites was selected to check the accumulation of cadmium in soil, water, forages and animals. These sampling sites was areas along the roadsides of Chak Jhumra, Jaranwala and Samundri. Sample of soil, forages,water and blood,hair feces of animals was collected from these sites. The digestion of samples was carried out with the help of nitric acid and hydrogen peroxide. Atomic absorption spectrophotometer was used to evaluate heavy metal analysis. Analysis of variance was done by using SPSS Software (version no. 20) and two ways ANOVA. Result indicated that concentration of Cd was higher in soil irrigated with municipal wastewater and concentration of Cd was highest in forages C. album present at site III. Higher concentration of Cd was observed in blood of sheep higher than critical value. Concentration of cadmium was higher than critical in blood of animals indicating transfer of metal via intake of contaminated forages. The sample collected from site III showed high daily intake of metals (DIM), health risk index (HRI), pollution load index (PLI), enrichment factor (EF) and Bioconcentration factor (BCF). This study will bring consideration concerning the development of approaches in order to overcome the toxic effects of cadmium.

The present research was performed to examine and compare the level of heavy metals in ginger (Zingiber officinale) irrigated with canal water and wastewater. Soil and vegetable samples were collected from two different areas irrigated with multiple water sources. Atomic absorption spectrophotometer was used for evaluation of metals, zinc (Zn), nickel (Ni), copper (Cu), cobalt (Co), manganese (Mn), lead (Pb), iron (Fe), and chromium (Cr). The metal accumulations in soil samples were ranged from 0.09 to 6.01 mg/kg. The metal accumulations in plant samples were ranged from 0.15 to 6.14 mg/kg. The Fe was found to be the heavy metal with the highest accumulation value in both sampling sites. The bioconcentration factor for Pb was highest at Site 1 and the lowest for Zn at Site 2. Pollution load index greater than one was obtained for Cr and Cd at both sites. Health risk index for all heavy metals was lower than 1 except for Pb and found in the following sequence: Pb>Ni>Cu>Cd>Fe>Zn>Cr>Co>Mn. Therefore, proper management strategies should be taken to reduce the extent of metal contamination in the food crop.

Present work evaluated the zinc (Zn) concentration in soil, forage, blood plasma, hair, and feces samples of cows, buffaloes, and sheep taken from Mianwali, Punjab, Pakistan. The concentration of Zn was found in the ranged of 21.82-35.09mg/kg, 32.59-42.17mg/kg, 0.927-2.48mg/l, 1.03-2.84mg/kg, and 0.923-1.98mg/kg in soil, forage, blood plasma, hair, and feces samples, respectively. The Zn concentration in soil, forage, blood, hair, and feces was safer compared to standard limits. Statistical analysis described that values for BCF, PLI, EF, DIM, and HRI ranged 1.03-1.57mg/kg, 0.486-0.782mg/kg, 0.457-0.696mg/kg, 0.048-0.08mg/kg, and 0.160-0.272mg/kg, respectively. It can be concluded from the present work that Zn concentration was safe in soil, forages, and animal samples. BCF was noticed as greater than 1 while PLI, EF, DIM, and HRI were found less than 1, so regular heavy metal analysis was required to appraise the contamination level in environment.

This investigation was done for the assurance of potassium amassing in four assortments of maize (grains, shoot and root), soil, and water and in seven tissues of chickens (kidney, liver, heart, bone, gizzard, breast meat). The analysis of variance showed significant differences for potassium concentration in water in all sources of water; however, the season and variety significantly influenced the quantity of potassium in cereals. The corn varieties MMRI, Sadaf, and Pearl behaved differently when treated with water from various sources. Water taken from sewage had a higher concentration of potassium compared to canal and groundwater that is why the maize plants irrigated with this water had a higher grouping. Data regarding potassium concentration in different body parts of chicken showed that season and treatment have a significant effect on the potassium concentration in chicken organs. The variety was non-significant for the potassium concentration only in the bone. Season × Variety interaction was only significant in blood, meat heart, and gizzard. Season × Treatment and Variety × Treatment interactions were significant in the heart, kidney, and gizzard. The potassium contents were higher in the chicken body parts that were reared on grains irrigated with sewage water as compared to other groups. The potassium contents were higher in the chicken meat (96.23 ± 0.00) reared on grains of the Pearl variety raised with the sewage water. In a nutshell, the irrigation of grains with sewage water led to accumulation of nutrients greater than those irrigated with ground or canal water.

The instant endeavor was undertaken for determination of lead (Pb) in water, soil, forage and cow’s blood domesticated in contaminated area of heavy automobiles’ exhaust in Sahiwal town of district Sargodha Pakistan. Water samples showed that the concentration of lead (Pb) ranged from 1.14 mg kg− 1 to 0.44 mg kg− 1 at all sites. It was maximum at site 5 and minimum at site 2. Soil samples showed the concentration of Pb at all sites ranged from 1.58 mg kg− 1 to 0.279 mg kg− 1. It was maximum in soil where Avena sativa was grown at site 5 and was found minimum in soil where Zea mays was grown at site 2. While among samples of forage, the concentration of Pb ranges from 0.048 mg kg− 1 to 2.002 mg kg− 1. The highest Pb amount was found in Brassica campestris at site 1 and the minimum was recorded in Trifolium alexandrinum at site 2. Finally, the blood samples of cow depicted that concentration of Pb ranged from 4.468 mg kg− 1 to 0.217 mg kg− 1. It was maximum at site 1 and minimum at site 3.

The instant endeavor was undertaken to monitor copper (Cu) contents in water, soil, forage, and cow’s blood impacted by heavy automobiles in Sahiwal town of district Sargodha, Pakistan. The samples were collected in triplicates with a total of 120 soil and water samples with corresponding forage samples. For the analysis of metal concentration in cows, 60 blood samples were collected from the cows feeding on these forages on selected sites. Metal contents were analyzed by atomic absorption spectrophotometry. The results showed that water samples contained mean values of Cu concentration ranged from 1.01 to 0.444 mg/kg at all sites. It was maximum at site 3 and minimum at site 6. The soil samples of all the forage fields showed Cu mean values concentration ranged from 1.94 to 0.286 mg/kg at all sites. It was maximum in Trifolium alexandrinum grown field at site 2, and minimum in Avena sativa at site 2. All the forage samples showed the mean value of Cu concentration ranged from 0.151 to 1.86 mg/kg at all sites. The concentration of Cu was maximum in Zea mays grown at site 5 and minimum in Trifolium alexandrinum at site 4. The cow blood samples showed the mean concentration of Cu ranged from 1.368 to 0.53 mg/kg at all sites. It was maximum at site 2 and minimum at site 6. Owing to the results of pollution index and transfer factors, metal content was found to be in permissible range in forages as well as animal samples.

Heavy metal contamination of food crops irrigated with municipal wastewater is a growing problem worldwide. In this direction, heavy metal accumulations in Abelmoschus esculentus crops were irrigated with three different water regimes (municipal wastewater, groundwater, and canal water) as well as in soil and the water sources were determined. Also, transfer factors, enrichment coefficients, pollution load indices, and health risk indices were assessed to understand the metal transportation and accumulation through the food chain. The concentrations of heavy metals in soil, water and plant samples were analysed by atomic absorption spectrophotometer equipped with a graphite furnace and D2 corrector (Perkin–Elmer Model 503). Heavy metal concentrations in the irrigation water samples ranged between 0.513–0.951 for Mo, 0.256–0.615 for As, 0.266–0.606 for Se, 41.604–54.642 for Fe, 0.285–0.753 for Cu, 0.255–0.619 for Zn, 4.684–5.212 for Ni, 3.792–5.526 for Pb, 0.035–0.065 for Cd and 2.635–4.608 for Co mg/L. The contents of Mo, As, Se, Fe, Cu, Zn, Ni, Pb, Cd and Co in soil samples ranged from 5.03 to 7.80, 34.27 to 38.96, 2.41 to 2.54, 4.77 to 5.94, 2.89 to 3.36, 1.76 to 3.63, 35.02 to 37.32, 25.10 to 28.12, 2.42 to 3.20, and 5.76 to 5.99 mg/kg, respectively, and the contents of Mo, As, Se, Fe, Cu, Zn, Ni, Pb, Cd and Co in A. esculentus samples ranged from 7.003 to 9.291, 2.800 to 3.585, 0.378 to 0.485, 39.718 to 44.048, 11.791 to 19.840, 28.203 to 37.051, 6.085 to 9.330, 4.885 to 7.061, 3.375 to 4.198, and 0.128 to 0.328 mg/kg, respectively. The range values of metal accumulation in A. esculentus samples were lower than the maximum permissible limits in plant samples except for Mo and Cd. Statistically, Se, Fe, Zn, Ni, Cd and Co concentrations did not vary significantly at all sites, while As, Mo, Cu, and Pb concentrations varied significantly in the vegetable samples.

Pakistan is an agricultural country and due to the shortage of clean water, most of the irrigated area (32,500 ha) of Pakistan was supplied with wastewater (0.876 × 109 m3/year). Concentrations of heavy metals in radish (Raphanus sativus) and turnip (Brassica rapa) taken from vegetable fields in Sargodha, Pakistan, were measured. Untreated wastewater was used persistently for a long time to irrigate these vegetable fields. A control site was selected that had a history of fresh groundwater irrigation. Mean metal concentrations were found for irrigation water, soil, and vegetables. In irrigation water, concentrations of Mo and Pb at three sites and Se at sites II and III were higher than the recommended limits. In vegetables, concentrations of Mo and Pb were above the maximum permissible limits. High bioconcentration factor was observed for Zn (12.61 in R. sativus and 11.72 in B. rapa) at site I and high pollution load index was found for Pb (3.89 in R. sativus and 3.87 in B. rapa) at site II. The differences in metal concentrations found in samples depended upon different soil nature and assimilation capacities of vegetables at different sites which in turn depended upon different environmental cues. The entrance of metal and metalloids to human body may happen through different pathways; however, the food chain is the chief route through which metals are transferred from vegetables to individuals. Health risk index observed for metals, (Mo, As, Ni, Cu, and Pb) higher than 1 indicated high risk through consumption of these vegetables at three sites.
