Methods for Assessing Exposure to Chemical Substances. Volume 6. Methods for Assessing Occupational Exposure to Chemical Substances

摘要

The report, one of a series of reports concerning exposure assessment, describes methods and catalogs informations sources for estimating exposure to chemical substances in the occupational environment. The report provides specific guidance for conducting the various component analyses of an occupational exposure assessment. It details approaches used to identify chemical manufacturing, processing, and use locations, and for determining the chemical processes used. The types of monitoring data useful in occupational exposure assessments are addressed, as are relevant QA/QC considerations. The mass balance approach to estimating workplace contaminant concentrations in the absence of pertinent monitoring data is detailed, as are methods for evaluating contaminant transport and transformation in the workplace, and attendant worker exposure pathways. Procedures for identifying, characterizing, and enumerating exposed worker populations are outlined, and methods are provided for calculating the level of exposure experienced by each population. The report concludes by providing two appendices. The first details the exposure potential associated with a number of major industrial processes, while the second identifies a large number of information sources useful in conducting occupational exposure assessments.
