What Are the Challenges in Establishing Safe Exposure Levels?
One of the main challenges in establishing safe exposure levels is the variability in individual responses to toxicants. Factors such as genetic predisposition and environmental influences can result in different susceptibility levels among individuals. Additionally, there is often limited data on the long-term effects of low-level exposure, especially for new or less-studied chemicals. As a result, regulatory bodies must sometimes rely on conservative estimates and safety factors to account for these uncertainties.
