Abstract

Chemical pollution has become a serious environmental problem in rapidly developing China since 1980s, and the environmental risk assessment of chemicals has increased attention from the government. This report briefly introduces the progress of risk assessment for environmental chemicals in China, the related challenges and research needs are also discussed. The Chinese government promulgated â�?�?Provisions on the first import of chemicals and the import and export of toxic chemicalsâ�? in 1994, â�?�?Measures on environmental management of new chemical substancesâ�? came into force in 2003, and was revised in 2010. These indicated that the management pattern of new chemical substances was converted from hazard assessment to risk assessment. In China, current environmental chemical risk assessment system includes qualitative ecological risk assessment, quantitative ecological risk assessment and qualitative health risk assessment. These three risk assessments are mainly composed by hazard assessment, exposure assessment and risk characterization to the environmental chemicals. Meanwhile, â�?�?the guideline for risk assessment of chemical substancesâ�? and â�?�?the guideline for hazard identification of new chemical substancesâ�? are established to protect the environmental ecosystem, ensure human health and regulate the chemical risk management and these two guidelines also provide technical support to the risk assessment of chemicals. Despite the good progress on risk assessment of environmental chemicals in China, the basic work still needs to be developed. Therefore, featured human and environmental exposure parameters based on characteristic of Chinese population and environment scenarios including suitable models applied in chemical risk assessment should be developed. Such researches will effectively promote the integration of chemical risk management in China.
