Chlorination is one of the most important methods used in water disinfection. Chlorine reacts with natural organic substances in water and causes the formation of disinfection byproducts that might cause health problems. The predominant by-product of chlorination is trihalomethanes. Humic substances, which make up the majority of natural organic substances, are the primary precursors of trihalomethanes. In this study, the effect of different doses of chlorine on the formation of chloroform, bromodichloromethane, dibromochloromethane and bromoform in the presence of natural organic matter and bromide in drinking water was evaluated. Artificial raw water samples prepared with the addition of 2, 3 and 5 mg/L humic acid representing natural organic matter were subjected to chlorination at doses of 1, 2 and 3 mg/L and analysed on the 0th, 3rd and 7th day. The only trihalomethane formed was chloroform with a concentration of 20.52-131.13 µg/L. Increased humic acid and chlorine levels resulted in increased chloroform content. Free chlorine in the water caused chloroform formation to continue even on the 7th day. Accordingly, the amount of chloroform formed increased with the contact time. While the chlorine dose was constant, increased humic acid resulted in decreased free chlorine. To evaluate the effect of bromide on trihalomethane formation, 200 µg/L bromide was added to 2 mg/L humic acid containing water, and 1 mg/L and 2 mg/L chlorination was applied. At the end of the chlorination process in bromide-free waters, only 23.46-41.90 µg/L of chloroform was formed. In the presence of bromide, chloroform, bromodichloromethane, dibromochloromethane and bromoform were formed and the total trihalomethane level increased to 50.03-85.59 µg/L. While the ratio of brominated trihalomethane increased, the amount of chlorinated species decreased. [ABSTRACT FROM AUTHOR]

The research was carried out in the ecological conditions of the Ranya region of Sulaymaniyah province, Iraq in the summer growing season of 2020. The goal of the study was to investigate the impact of humic acid on the growth and yield of corn. The trial included two commercial cultivars (DKC6050 and DKC6664) and soil application of four rates of humic acid (HA1: 0 kg/ha, HA2: 60 kg/ha, HA3: 120 kg/ha and HA4: 180 kg/ha). The experiment was conducted according to the split-plot experimental design in randomized blocks. In the study, a trial pattern was designed so that varieties were placed in the main plots, and doses of humic acid were placed in the subplots for a more precise investigation of their effects on the cultivars. In the experiment, the characteristics of growth, yield, and yield components were examined. According to the results, it was determined that applying humic acid positively affected all vegetative and yield parameters except for the germination time, cob diameter, protein ratio, and oil ratio. As the result of the interaction between the cultivars and the humic acid doses, significant results were obtained for seed yield, 100 seeds weight, yield per plant, cob diameter, harvest index, leaf area index, stem diameter, and silk appearance time. The highest grain yield was obtained from the DKC6050 variety (9844.8 kg/ha). Responses of cultivars to humic acid were the same and therefore no appreciable differences were observed between cultivars for comparison. However, it has been determined that the DKC6050 variety is a promising variety in terms of many characteristics and can be cultivated in the ecology where the research is carried out.

The study was carried out in a randomized plot design with three replications, with 4 pots in each replication and 3 plants in each pot. A total of 10 applications consisting of liquid compost (25%- 50%), vermicompost (25%-50%), and humic acid (600-1200 ppm) and combining these applications were applied to Zinnia seedlings. The first application was applied as 400 mL per pot when the plants reached 20 cm in size. Applications were made 3 times with an interval of 7 days. When the plants are harvested, flower diameter (mm), stem thickness (mm), number of flowers (piece), stem length (cm), number of branches (pieces), the weight of branches (g), number of leaves (pieces), root length ( cm), root fresh weight (g), root dry weight (g), vase life (days) parameters were examined. As a result of the study, the highest flower diameter (72.27 mm) and SPAD value (34.93) was 600 ppm humic acid application, the highest flower stem thickness (4.67) and flower stem length (45.56 cm) 25% liquid compost + 25% vermicompost application, the highest flower stem thickness (4.67). The number of flowers (6.17 pieces) and root wet weight (8.10 g) were found in 25% vermicompost application, the highest number of branches (7,25) in 1200 ppm humic acid application, the highest branch weight (30.76) in 50% vermicompost application. As a result, it was observed that in applications where 25% of vermicompost was used, it had positive effects on the number of leaves, flowering, and root parameters. In humic acid applications, it has been found to have a positive effect when used at low rates such as 600 ppm. It is stated in the results of the study that the doses used to give better results when applied at low rates.

Background: The purpose of the present study was to examine the effects of topical humic acid application on healing in oral mucosa wound in rats. Material and Methods A total of 12-week-old 72 Wistar male rats weighing 280-300 gr were used in the study. The rats were randomly grouped in 4 groups as the Control Group (K) to which no applications were made, Chlorhexidine (0.12%) Group (CHX), 80 mg/kg Humic Acid Group (HA80), and 150 mg/kg Humic Acid Group (HA150). Mucosal defects of 5-mm-diameter were induced with punch in the palatal areas of the rats. These groups were further divided into 3 sub-groups to be sacrificed on days 7, 14 and 21. Epithelization, ülceration, polymorphic nuclear leukocytes (PNL), mononuclear cells (MNL), fibroblast and vascularization were examined in histopathologic evaluations. In addition, photos of the tissue samples were taken and transferred to the computer medium for histo-morphometric examinations. Results As a result of the statistical analyses, no significant differences were detected among the groups in terms of epithelization degree, PNL and MNL cell infiltration on days 7, 14 and 21. The ulcerated areas were low in HA150 Group compared to the other groups, and there was a significant difference in this respect (p0.05). Wound area measurement scores were lower in HA150 Group compared to the other groups, and this result showed that the healing in HA150 Group was better (p

Bu çalışmada; ülkemizde ve dünyada en çok kullanılan bitki besleme ve toprak düzenleyici ürünlerden biri olan humik asitin üretiminde, geleneksel karıştırma metodları yerine kaotik sistemler kullanılarak, ürün kalitesi, homojenlik, zaman ve enerji tasarrufu gibi önemli kriterler açısından karıştırıcıların verimlerini arttırmak hedeflenmiştir. Kaotik sistemlerin bu özelliklerinden yola çıkılarak deneysel çalışmalar için; tüm fonksiyonları HMI (Human Machine Interface) operatör panel tarafından kontrol edilebilen, PLC (Programmable Logic Controller) kontrollü bir karıştırıcı tasarlanarak imalatı gerçekleştirilmiştir. Bu karıştırıcıda, su, leonardit ve potasyum hidroksit (KOH) karıştırılarak, sıvı humik asit elde edilmiştir. Karıştırma işlemi için literatürden farklı dinamik özelliklerde kaotik sistemler seçilmiştir. Bu kaotik sistemlerin diferansiyel denklemleri, Labview programında geliştirilen bir ara yüz programında Runge Kutta 45 (RK45) sayısal çözüm algoritmasına göre çözdürülerek her kaotik sistemin kaotik zaman serisi sonuçları elde edilmiştir. Bu sonuçlar, PLC cihazına yazılan program ile frekans verilerine dönüştürülerek frekans invertörüne bağlı karıştırıcı motorun, seçilen kaotik sistemlere göre değişken hızlarda dönmesi sağlanmıştır. Aynı karışım geleneksel yöntemlerle (sabit hız) de elde edilerek, ürün kalitesi, çözünen madde oranı, pH değerleri ve toplam enerji tüketimi açısından karşılaştırmaları yapılmıştır. Elde edilen sonuçlara göre; kaotik sistemler kullanılarak yapılan karıştırmanın, ürün kalitesi, homojenlik, zaman, enerji tasarrufu gibi kriterler açısından geleneksel karıştırma yöntemlerine göre daha verimli olduğu gözlemlenmiştir.

Magnetite (Fe3O4), Humic Acid (HA) and Silver (Ag) are materials with important properties. Synthesizing a single material which will have all the properties of these materials can provide significant advantages for some application areas. In this study, synthesized Fe3O4@HA@Ag was doped into poly(vinyl pyrrolidone) (PVP), in weight ratios of 5%, 7.5% and 10%, and nanofiber production was carried out by electrospinning method. Structural properties of nanofiber structures were investigated by X-ray Diffraction (XRD), morphological properties by Scanning Electron Microscope (SEM), spectroscopic and thermal characterizations by Fourier transform infrared (FTIR) and Thermogravimetric Analysis (TGA). When the analysis results of nanofibers were evaluated, it was determined that Fe3O4@HA@Ag doped PVP nanofibers were successfully produced. [ABSTRACT FROM AUTHOR]

In this study, the extraction of humic acid from low-quality lignite samples obtained from Arguvan (Malatya) coal deposit was investigated using the California Department of Food and Agriculture (CDFA) method. In leaching experiments, raw coal (i.e. unwashed coal) sieved in different particle size and washed coals with different specific gravities obtained from float-sink test were used. Each coal sample was individually leached in alkaline media prepared using NaOH, KOH and Na4P2O7. Then, humic acid yield (%) of coal samples was determined by precipitation of humic acid from leach solution. As a result of the experiments performed under ideal leaching conditions, the humic acid yields obtained from the run-of-mine and washed coal samples were compared and it was concluded that coal washing had a positive effect on the humic acid yield.

This study was carried out in Konya Soil, Water and Combating Desertification Research Station in 2015 in order to determine the effect of humic acid applications in different amounts on the development and quality properties of some potato varieties in Konya ecological conditions. Three different potato varieties (Agria, VR808, Brooke) and four different humic acid doses (0, 3, 6, 9 L da-1 ) were used in this study, which was established in three replications according to "The Randomized Complete Block in a Split Plot Design". In the study, large, medium, small, discarded tuber yields per decare, protein content, specific gravity, chips yield, oil holding capacity of chips, dry matter content, starch content were investigated. It was determined that there was a significant increase in humic acid applications in large, medium, small and discarded tuber yields per decare. Oil holding capacity of chips was between 32.9 % and 46.2 %, starch content was between 11.7 % and 17.3 %, and the differences between humic acid applications were found to be statistically significant for these properties. In terms of chips yield and protein content, statistical significance was not determined among the applications. Considering all the properties examined, it was determined that increasing humic acid applications positively affected the yield of large, medium and small discarded tubers per decare and significant variations were obtained among some quality properties of the varieties.

This study was carried out to determine the effect of different humic acid application methods on soil nutrients content in cotton. The study was conducted at Siirt University Faculty of Agriculture Department of Field Crops experimental area in 2016. In the experiment Stoneville 468 cotton variety and TKI Humas humic acid (5% organic matters, 12% humic+fulvic acid, 3% water soluble potassium oxide) were used as material. Seven different humic acid applications were performed as Control, To Soil, To Seeds, Leaves at Pre-Flowering Stage, Leaves at Flowering Stage, Soil + Leaves at Pre-Flowering Stage and Seeds + Leaves at Flowering Stage. The results of soil analysis indicated that there were significant differences between humic acid application methods in terms of potassium, calcium, sodium, magnesium, zinc and copper content of soil, but there was nonsignificant for that of nitrogen. The application of humic acid on seed treatment increased the potassium, calcium, magnesium, iron, manganese and copper content of soil. Additionally, at pre-flowering stage application of humic acid to the leaves increased the content of phosphorus in the soil, the highest zinc content obtained from application at flowering stage. According to the results of study it was concluded that nutrient content of soil increased by application of humic acid, the best response observed from application at pre-flowering stage to the leaves and seeds, in addition, soil humic acid application led to decrease K, Ca, Na, Mg and Cu values of soil.

In this study, it was aimed to demonstrate the effect of humic acid applications on some morphological, physiological and biochemical characteristics of eggplant genotypes (Burdur Merkez, Burdur Bucak, Kemer and Giresun) irrigated with the irrigation water with a high content of heavy metal and determined previously salt tolerance levels. In studies conducted in controlled greenhouse conditions, eggplant seeds germinated in the growth substrate a mixture of peat and perlite and the seedlings were transplanted into pots at 20 days after sowing. Plants when they are 4-5 true leaves, 3 different humic acid levels (0, 500, 1000 ppm) have been applied and 7 days later after this application began to be watered with 3 different irrigation water comprising a mixture of various doses of heavy metals (control: 0 ppm; I. Mixture: 0.2 ppm 5 ppm to 0.01 ppm Cd + Cu + Pb + 2 ppm Zn, II. mixture: +0.02 ppm 0.4 ppm Cu 10 ppm Pb + Cd + 4 ppm Zn). Field capacity level for the plants 40 days after quenched with water after which time they were harvested and samples for analysis were performed. In the study plants were investigated for shoot and root fresh weight, shoot and root dry weight, shoot and root length, leaf area, chlorophyll and MDA level of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR) enzyme activities All genotypes are adversely affected by heavy metal applications. In parallel to increase the dose, heavy metal mixtures led to a reduction in values of fresh and dry weight of shoot and root, stem and root length, leaf area of eggplant genotypes. MDA and antioxidative enzyme activities increased in plants irrigated with water containing a mixture of heavy metal. Humic acid applications had a positive effect on reducing of the limiting effect of heavy metal stress on growth and development. As a result, compared to sensitive genotypes Giresun and Kemer, salt tolerant genotypes Burdur Merkez and Burdur Bucak showed much better resistance to abiotic stress factor which consists of heavy metal applications. The obtained results; formed also an opinion about that plants evolved similar strategies for resistance to abiotic stresses such as salinity, drought and heavy metal stress.

Objective: The aim of the present pilot study was to evaluate the effects of a single local dose administration of humic acid on healing of subcondylar mandibular fractures in rats. Methods: In this study, a randomized experimental protocol was used. The study was conducted with 16 male Wistar-albino rats that were 16-18 weeks old. The rats (n=16) were randomly divided into two groups: Group HA received humic acid (0.3 cc/site, n=8) and Group C received no additional medical administration (control group, n=8). A full-thickness surgical osteotomy was performed in the subcondylar area. A single dose of humic acid (0.3 cc/site) was administered locally by spraying on the bone surfaces of the fracture line. Mandible was dissected on postoperative day 21. Then, fractured hemimandibles were obtained for histopathological examination. Results: The median score of bone fracture healing was 7.16 (range: 7 to 8) in the Group HA and 7.50 (range: 7 to 8) in the Group C. When the groups were compared in terms of bone healing scores, there was no statistical difference between the Group HA and the Group C (p>0.05). Conclusion: Results of this study showed that local administration of humic acid was not efficient for healing of bone fractures. However, we are of the opinion that it is required to conduct more comprehensive studies, including humic acid's different concentrations and administration manners, evaluating the effects of humic acid on tissue both histopathologically and in terms of inflammatory and proinflammatory cytokine levels.

Bu araştırmanın amacı, artan dozlarda arıtma çamuru (0, % 10, % 20 ve % 30) ve humik asit (0, 1000, 1500 ve 2000 ppm HA) uygulamalarının kireçli bir toprakta yetiştirilen mısır bitkisinin gelişimine, besin elementi ve ağır metal kapsamları ve hasattan sonra uygulamaların bazı toprak özelliklerine etkilerini belirlemektir. Artan dozlarda uygulanan arıtma çamuru, hasattan sonra deneme toprağının pH ve kireç içeriğinde azalmalara neden olurken, toprağın tuz, organik madde P, Ca, Mg, Fe, Mn, Zn, Cu, Cd, Ni, Pb ve Co içeriklerinde önemli artışlara neden olmuştur. Arıtma çamuru dozları mısır bitkisinin kök ve kök üstü aksamlarının yaş ve kuru ağırlıklarını ile bitki boyunu önemli olarak artırmıştır. Artan arıtma çamuru ile mısır bitkisi kök P, K ve Zn, mısır kök üstü kısımlarında ise P, K, Ca, Mg, Fe, Mn, Zn, Cu, Cd, Ni, Pb ve Co içeriklerinde önemli artışlar saptanırken, kök Fe, Mn, Cd, Ni, Pb ve Co içeriklerinde önemli azalmalar saptanmıştır. Artan dozlardaki humik asit uygulamaları toprağın organik madde ve alınabilir P, Ca ve Mg içerikleri üzerinde önemli etkide bulunurken, diğer toprak özelliklerine önemli bir etkisi saptanmamıştır. Mısır bitkisinin kök ve kök üstü kısımlarının yaş ve kuru ağırlıklarını ile bitki boyu HA’nın 1000 ppm’lik dozuna kadar artmış bu dozdan sonra önemli olarak azalmışlardır. HA uygulamaları ile mısır bitkisi kök mikro element içeriklerinde azalmalara neden olmasına rağmen bu azalmalar istatistiksel olarak önemli bulunmamıştır. Sonuç olarak, çalışma koşullarında mısır bitkisi için arıtma çamurunun %20’lik, humik asitin 1000 ppm’lik dozlarının uygun olduğu kanısına varılmıştır.

This study investigated the effect of different levels of humic acid on some rumen and blood parameters and rumen protozoa in Norduz sheep. The study was designed and conducted in four-factor repeated measures analysis of variance. Totally 24, approximately 16-week old, female Norduz sheep were used in the study. Four feeding groups were designed. The first group was not given humic acid (C, control GI); the second group was given humic acid of 0.015% of the live weights of the sheep (GII); the third group was given humic acid of 0.030% of the live weights of the sheep (GIII); the fourth group was given humic acid of 0.060% of the live weights of the sheep (GIV). A total of eight sheep having similar ages and live weights were randomly distributed to each group (live weights of 40.230±1.25). The feed consumed by the sheep was limited to 2.5% of their live weights. Blood and rumen fluid samples were collected 2 times (before the test and on 25th day of the test). Comparison of some blood parameters were collected from the animals before and after the test revealed no significant difference in serum triglyceride and rumen pH levels. It was observed that while live weight, blood serum total protein, blood serum potassium, chloride, and sodium levels decreased (P< 0.05), blood urea and number of rumen protozoa increased (P< 0.05). Considering the values obtained before and after the test, the use of humic acid increased the number of rumen protozoa without negatively affecting blood parameters. [ABSTRACT FROM AUTHOR]

This study has been conducted to find out the effects of foliar treatments of seaweed (SW) and humic acid (HA) on cv. Riesling wine grape throughout ripening period from veraison period to harvest period at 15 days of interval. Such as veraison period, 15 days after veraison period and 30 days after veraison period aimed to examine the biochemical variations in berry. In this research, the doses of 0, 1000, 2000 ppm of SW and HA treatments have been selected, and applied to grapevines three times at different phenological stages of grapevine. Among the berry sampling, in terms of measurement and analysis, the best quality characteristics were respectively obtained from the period of 30 days after veraison, 15 days after veraison and veraison, and the results showed that the foliar sprays of SW and HA could modify the biochemical characteristics of berries in cv. Riesling. In terms of free volatile terpenes (FVTs) and potentially volatile terpenes (PVTs) of berries, which are also very important for aromatic grape cultivars, 1000 ppm doses of both of SW and HA treatments respectively displayed the highest contents in FVTs (0.880 and 0.804 mg L-1) and PVTs (2.153 and 2.084 mg L-1). Consequently, 1000 ppm doses of SW and HA foliar treatments provided the best improvements in most quality characteristics of berry when they were harvested at 30 days after veraison period.

Bu çalışmada alternatif bir demir kaynağı olarak, Ereğli Demir Çelik Fabrikaları baca filtresi atığındaki demirden yerfıstığı bitkisinin yararlanmasına humik asitin (Polymeric polyhydroxy asit % 85 w/w) in etkisi asit, nötr ve alkali özellikteki üç farklı toprakta araştırılmıştır. Bitkilerin kuru ağırlıkları üzerine atık demir ve humik asit uygulamalarının bir etkisi olmamıştır. Atık demir özellikle humik asit ile birlikte uygulandığında bitkilerin aktif demir, toplam demir ve klorofil içerikleri artmıştır. Buna karşılık yaprak renginin ve parlaklığının bir ölçüsü olan L, a, b değerleri, atık demir ve humik asit uygulamasıyla azalmıştır, bir başka ifade ile yaprakların rengi koyulaşmıştır. Yaprakların L, a ve b değerleriyle klorofil içerikleri arasında negatif yönde önemli korelasyonlar belirlenmiştir.
