Details
Chemicals that are highly persistent but do not accumulate in living organisms can remain in water for a long time. Concerns are growing internationally that current regulatory processes may not adequately control risks. They have the potential to travel to areas far from the point of release, where they may eventually reach concentrations that could result in adverse environmental effects.
This project found a standard exposure model can identify highly persistent chemicals for which a more conservative regulatory assessment may be appropriate. This work is important for determining and prioritising the potential hazard and risk management of these chemicals.
