|Roles of Exposure Assessments and Limits in Risk Analysis|
|Exposure assessments and the limits to which they are compared are valuable arrows in the product steward’s risk analysis quiver. Used appropriately they indicate whether the anticipated level of exposure can be typically experienced without adverse health effects. Used inappropriately they can confuse or mislead even the seasoned practitioner and misrepresent the true risks associated with an intended use. A cornerstone to their appropriate use is the transparency regarding the basis, intent, and fit-for-purpose of the exposure limit and the adequacy with which the exposure assessment represents the intended use. Understanding fit-for-purpose is the key to appropriately utilizing exposure limits from a variety of sources and systems, while key for an adequate, but still cost-effective exposure assessment, is the tiered assessment approach. Exposure limits and assessment methodology continue to be one of the nuances in doing business across a global marketplace where product stewards can add business value.
