Background



Living organisms interact regularly with chemical and microbial agents in our environment, in our food, and in the products we use everyday. Risk assessment seeks to understand the body or ecosystem's response to those interactions, with the goal of identifying adverse effects, and quantitatively estimating levels of exposure that are unlikely to produce negative consequences.

Ultimately, the risk assessment determines the magnitude of a specific risk so that decision makers (risk managers) can conclude whether the potential hazard is sufficiently great that it needs to be managed or regulated, reduced, or removed. (EPA)
