China Issues Guideline For Environmental Risk Assessment Of Chemical Substances
On September 3, 2019, the Chinese Ministry of Ecology and Environment (MEE) and National Health Commission (NHC) jointly issued a final Technical Framework Guideline for Environmental Risk Assessment of Chemical Substances (Trial). This Trial Guideline provides a basic framework, including evaluation steps, technical requirements, and report preparation, for the environmental risk assessment of a single chemical substance under standard production and uses. The Trial Guideline does not apply to mixtures or exposures due to accidents or leakages. The “four-step” evaluation includes hazard identification, dose-response assessment, exposure assessment, and risk characterization. It also outlines uncertainty analysis, data quality assessment, spatial scale of exposure assessment, risk assessment of persistent, bioaccumulative, and toxic (PBT) and very persistent and very bioaccumulative (vPvB) chemical substances, and consideration for risk assessment of metals and their compounds.
