Impact of the Pb and Zn ore mining industry on the

The Biała Przemsza River water is mainly loaded with metals. Toxic concentrations of Cd, Pb, and Zn were observed at sampling points in Okradzionów and Sławków. The toxic Tl concentration was exceeded (26 μg/L) at three sampling points. The Biała Przemsza River bottom sediments were composed mostly of medium and fine sand.
