The role of plants in the remediation of contaminated soils

摘要

Accumulation of organic or mineral micropollutants in soils and waters may alter the functioning of ecosystems and contaminate the food chain. The remediation of these contaminated environments by currently available physico-chemical methods is either costly or impossible. Phyto-remediation, i.e. remediation based on the use of plants, would be more economic and more environmentally friendly, leaving soil material without major alterations in biological properties.
