Draft Guidelines for Human Exposure Assessment
The US Environmental Protection Agency (USEPA) is currently soliciting feedback for its Draft Guidelines for Human Exposure Assessment. The current guidance document for human exposure assessment, Guidelines for Exposure Assessment, was published in 1992 and incorporates exposure assessment knowledge that was formulated in the 1970s and 1980s. The updated guidelines expand upon topics currently included in the guidance document, including planning and scoping for an exposure assessment, data acquisition and use, modeling, and consideration of uncertainty. New information regarding planning and conducting an observational human exposure measurement study, as well as considerations of different life stages and sensitive populations in exposure assessments, have also been added to the guidelines. The deadline to submit comments on the draft document is February 22, 2016.
