摘要
The disposal of waste at wild dumpsites poses significant environmental challenges. This study evaluates heavy metal (HM) contamination in soil around wild dumpsites in Bijeljina-Zvornik, Republic of Srpska, Bosnia and Herzegovina. Forty-five soil samples were analyzed for Ni, Cr, Mn, Zn, Cu, Pb, Cd, Fe, and Al. The highest concentrations observed were for Fe (average 9211.96 mg/kg, maximum 33,275.16 mg/kg) and Zn (average 109.76 mg/kg, maximum 1054.24 mg/kg). The highest daily total exposure dose (ADD) for both adults and children was for Fe, with ADDing for children at 7.07E-01 mg/kg/day and for adults at 3.03E-01 mg/kg/day. Hazard quotient (HQ) contributions to non-carcinogenic exposure risk (HI) were 99.93
