Abstract

Heavy metal pollution of agricultural soils and crops through the applications of MSW (Municipal Solid Waste) compost and sewage sludge are of great concern. Although MSW compost provides nutrients for plant growth, its continual use over extended periods can result in the accumulation of heavy metals in soils and in the crops to levels that are detrimental to the food chain. Contamination of soils by potentially toxic elements (e.g. Zn, Cu, Ni, Pb, Cd) from amendments of sewage sludge and MSW compost is subject to strict controls within the European community in relation to total permissible metal concentrations, soil properties and intended use.
