Exposure to a chemical via air, water or food can result in the impairment of health,
depending on the degree of exposure and the toxicity of the substance. Health-based recommended exposure limits for a substance correspond with the highest estimated dose or concentration that does not lead to health impairment. To support the implementation of policy on industrial safety, environmental management and food safety, the Health Council derives such limits for specific substances. The Council also studies the methods employed to derive recommended exposure limits, and from time to time it advises modifying these methods to bring them into line with the latest developments in scientific knowledge.
This document, drawn up by the Health Council’s Committee on the Derivation of
Health-Based Recommended Exposure Limits, forms one such methodological advisory report.
