The accumulation of potentially toxic elements in spinach biomass grown on nine soils treated with sewage sludge.

摘要

The effect of sewage sludge application on nine arable soils (2 Luvisols, 2 Chernozems, 3 Cambisols and 2 Fluvisols) with different properties was investigated in pot experiments with spinach cv. Monores. The presence of 8 elements (As, Cd, Cr, Cu,Hg, Ni, Pb and Zn) in the sludge applied, their availability in soil and their uptake by the spinach plants were investigated and results are discussed.
