Update and Refinement of an Indoor Exposure Assessment Methodology

摘要

The primary mission of the ARB Indoor Program is to identify and reduce Californians' exposures to indoor pollutants. To fully consider indoor exposures in assessing risk, the ARB needs estimates of average and peak indoor exposures for the general California population as well as certain subgroups of that population such as individuals who may be highly sensitive to indoor pollutants. The model described in this document--California Population Indoor Exposure Model, Version 2 (CPIEM 2.0)-is a software product that has been designed to expedite the exposure-assessment process by providing a user interface and calculation tools for supplying and integrating all required information. It is an enhanced version of the original CPIEM 1.4F released by ARB in 1998.
