Abstract

The water quality of the Czarna Przemsza River source in Zawiercie was investigated in four sampling campaigns in years 2016 and 2017. Values of 62 indicators (physico-chemical, inorganic, organic, and biological) were compared with permissible limits for drinking water according to Polish legal acts and EU, WHO, USEPA, and Canadian guidelines. The water quality was determined as below good because of EC values and As, Ca, Cd, Cr, Cu, Se, and Zn concentrations. Water was also determined as non-potable due to exceeded concentrations of Al, As, Cd, Cr, Fe, K, Ni, Pb, Sb, and Se. The Human Health Risk Assessment for Zawiercie's inhabitants was carried out, while water from the source is consumed regardless of its quality. The mean estimated daily intake (EDI) values exceeded Minimal Risk Level values forCr, Cd, As, Se, and Cu. The hazard index (HI) values pointed very high total non-carcinogenic risk in residential exposure scenario generated mainly by As, Cr(VI), Tl, Pb, MCPA, Se, and Cd. Water intake scenario based on questionnaire surveys pointed that risk for inhabitants existed (HI >1). The total carcinogenic risk (Rt) values were at the unacceptable level and decreased in the following order: Cr(VI) > As > Pb. [ABSTRACT FROM AUTHOR]

Abstract

Agricultural soil samples were collected from the areas where edible plants had been cultivated in southern Poland. The PHE content decreased in proportion to the median value specified in brackets (mg/kg d.m.) as follows: Zn (192) > Pb (47.1) > Cr (19.6) > Cu (18.8) > Ni (9.91) > As (5.73) > Co (4.63) > Sb (0.85) > Tl (0.04) > Cd (0.03) > Hg (0.001) > Se (< LOQ). No PHE concentrations exceeded the permissible levels defined in the Polish law. The PHE solubility (extracted with CaCl2) in the total concentration ranged in the following order: Fe (3.3%) > Cd (2.50%) > Ni (0.75%) > Zn (0.48%) > Cu (0.19%) > Pb (0.10%) > Cr (0.03%). The soil contamination indices revealed moderate contamination with Zn, ranging from uncontaminated to moderately contaminated with Pb, and, practically, no contamination with other PHEs was identified. The ecological risk indices revealed that soils ranged from uncontaminated to slightly contaminated with Zn, Pb, As, Cu, and Ni. The PCA indicated natural sources of origin of Co, Cu, Hg, Sb, Zn, Cr, and Pb, as well as anthropogenic sources of origin of Cd, Ni, As, and Tl. The human health risk assessment (HHRA) for adults and children decreased in the following order of exposure pathways: ingestion > dermal contact > inhalation of soil particles. The total carcinogenic risk values for both adults and children were at the acceptable level under residential (1.62E−05 and 6.39E−05) and recreational scenario (5.41E−06 and 2.46E−05), respectively, as well as for adults in agricultural scenario (1.45E−05). The total non-carcinogenic risk values for both adults and children under residential scenario (1.63E−01 and 4.55E−01, respectively), under recreational scenario (2.88E−01 and 6.69E−01, respectively) and for adults (1.03E−01) under agricultural scenario indicated that adverse health effects were not likely to be observed. Investigated soils were fully suitable for edible plant cultivation. [ABSTRACT FROM AUTHOR]
