摘要

Risk assessment provides a scientific basis for evaluating potentially toxic chemicals.Central in the concept of risk is its dependence on both exposure and toxicity.Chemicals will only express their toxicity when these exceed a concentration at which a defined target becomes affected.While this is a trivial remark among environmental risk assessors,the new chemicals policy of the EU tends to divert into a different direction.The communication of the European Commission on its new Chemicals Policy places an emphasis on hazard-based chemical management.We urge the Commission to reconsider this view.We believe that for the majority of chemicals evaluated under REACH,a scientifically sound risk assessment evaluating both exposure and effect should remain the core of the EU strategy"towards a toxic-free environment".
