Accumulation and bioavailability of heavy metals in a soil-wheat/maize system with long-term sewage sludge amendments
A long-term field experiment was carried out with a wheat-maize rotation system to investigate the accumulation and bioavailability of heavy metals in a calcareous soil at different rates of sewage sludge amendment. There are significant linear correlations between the contents of Hg, Zn, Cu, Pb, an...
