Description

Contamination of soils and sediments by organic chemicals is a major threat to the environmental quality of freshwater and groundwater resources. At present, assessment of the risks of soil and sediment contamination is based on the assumption of bulk organic carbon-based equilibrium partitioning. However, it is generally accepted in scientific circles that this assumption is inappropriate and can lead to an overestimation of the risks of soil and sediment contamination. This project will investigate the mechanistic basis for the formation of different sorbed fractions of contaminants in soils and sediments and the bioavailability of these fractions. Methods will be developed to easily determine bioavailable fractions of contaminants in relation to their sorption kinetics. These results will be exploited to develop protocols for the risk assessment of sorbed contaminants in soils and sediments.
