Geochemical fractionation and environmental risk assessment of potentially toxic elements (Cu, Zn, Pb, Ni, Cr, Ba, Mn) in Tokaj vineyard soils, Hungary

Abstract In our study, the sequential extractions and environmental risk assessment of Cu, Zn, Pb, Ni, Cr, Ba, Mn were performed in soil depth profiles and in sediments transported by surface runoff in two vineyards with contrasted soil pH in NE Hungary. Our data indicate that while both sites showed Cu contamination from fungicide applications, the slightly acidic soil in Tállya had considerably higher Cu levels (131 ± 38 mg/kg) than the alkaline soil in Tokaj (51 ± 15 mg/kg) due to longer-term
