Abstract
Performing an exposure assessment in occupational epidemiology studies requires the collection of a wide variety of exposure data, because there are usually too few biological or air monitoring measurements over the time period of interest to allow retrospective assessment of exposures for individual study subjects. This article describes different types of exposure data that can be used to supplement monitoring results and provides a brief description of how they might be used. It also identifies sources from which these data may be obtained and the resources that may be needed to collect them.
