The bioaccumulation of heavy metals inBrassica napusL. in the area around Turów Power Station, Poland

Abstract

Abstract. Brassica napus L. is a known bioaccumulator of copper, zinc, cadmium, lead, chromium, nickel and arsenic from soils. The metal ions are accumulated in the roots, stems, leaves and seeds of the oilseed rape. The samples of soils and plants were collected in the area around the Turów power station (Bogatynia city, Lower Silesia). The soil samples were collected from the surface layer of 0-25 cm. Roots, stems and pods of the oilseed rape were used in the study. The environmental samples were digested in HNO 3 , 60%, using the Microwave Digestion System. Metal concentrations have been dermined through the FAAS method. Three heavy metals -zinc, copper and lead -have been analyzed. The content of zinc was higher than the content of copper in all samples (plants and soils). In the roots of the oilseed rape higher concentration of metals compared to other parts of the plant was observed. In the soil samples, there was no correlation between the concentration of pollution and the distance from the power plant. Permissible concentrations of heavy metals relative to the standard according to the Polish Ministry of Environment Regulation from September 1 st , 2016, have not been exceeded. The permissible pollution indexes (Wn) in soils were exceeded compared to the geochemical background in uncontaminated soils of Poland. The bioaccumulation coefficients of heavy metals indicate lower metal concentrations in plants than in soils
