H. zkaynak, US Environmental Protection Agency, National Exposure Research Laboratory, Research Triangle Park, North Carolina Aggregate exposure assessment must account for exposures by all media and by all significant routes. Data on human activity patterns are an essential component of estimating total personal exposures to environmental contaminants.
Preliminary results show the youngest age group has the highest potential exposures.
Both the variability and uncertainty of predicted exposures are found to be very high. This work has been funded in part by the United States Environmental Protection Agency. It has been subjected to Agency review and approved for publication.
