Possibilities of implementation of bioavailability methods for organic contaminants in the Dutch Soil Quality Assessment Framework

► Currently SQS are determined based on total concentrations in soil. ► Including bioavailability gives a more effect based risk assessment for soils. ► We advise on implementing the use of bioavailability in regulatory frameworks. ► Actually bioavailable soil concentrations can be related to aquatic toxicity data. ► Potentially bioavailable soil concentrations can be related to soil toxicity data.
