Heavy metals cumulation in soils after the sewage sludge application

Abstract

During 1995-1996 the soil samples after the sewage sludges application were collected. The heavy metals cumulation in soil samples from Bardejov increased in order: Pb > Zn > Cu > Ni > Cr > Cd and Banská Bystrica: Zn > Pb > Cu > Ni > Cr > Cd. The heavy metals contents after the sewage sludge application were increased in comparison with the highest admissible concentration in soils.
