Environmental exposure assessment

The objective of an environmental exposure assessment is to provide a quantitative and qualitative estimate of the substance dose or concentration to which the population and the environment may be exposed. It may consider all stages of a substance’s life cycle – production, uses and waste - in order to estimate the amount of emissions released and environmental concentrations.

EU REACH initiated the development of exposure assessment and it enforces a strict process for substances to be evaluated on the basis of hazard and risk throughout the supply chain. Since then TSCA in the US has also evolved in that direction.
