Tools for Exposure Assessment
Several tools exist for performing exposure assessments including monitoring data, exposure models, and the use of analogous data from existing chemicals. The following sections discuss these tools and their potential usefulness in assessing exposure to nanoscale materials.
3.5.6.1 Monitoring Data
Types of monitoring data that can be used in exposure assessment include biological monitoring, personal sampling, ambient air monitoring, worker health monitoring and medical surveillance. Although monitoring and measurement are discussed earlier in section3.4, the discussion below includes coverage of some issues directly pertinent to exposure.
