APPROACHES FOR HIGH TIER AGGREGATE ASSESSMENT OF CHEMICALS

This chapter gives an overview of current approaches to aggregate exposure assessment and examples of aggregate exposure assessment published in the literature. An outline of a tiered approach to aggregate exposure assessment from WHO/IPCS (Meek et al, 2011) is shown in Figure 1 of Section 1.1. In this section the tiered approach to exposure assessment is illustrated using two case studies: 1) triclosan in cosmetic products, and, 2) phenoxyethanol in cosmetic and household products.
