    Over the last three decades, significant progress has been made not only in the technology of measuring air contaminants but also in the statistical descriptions of exposure distributions and exposure assessment strategies. Occupational Exposures for Air Contaminants addresses the various aspects of occupational exposure assessment for air contaminants as a coherent body of knowledge. It is the first book to explore occupational air contaminant measurement and properties, human exposure assessment, design of exposure strategies, and the statistical interpretation of exposure measurements in one comprehensive source.

    The book describes the process of obtaining a number that represents the value of exposure to an air contaminant and the science and technology underlying this process. It includes a discussion of sources of variability in exposures, the statistics of exposure distributions, and exposure assessment strategies for routine monitoring as well as occupational epidemiology. The book's all-inclusive exploration of the major theories and practices of occupational exposure assessment for air contaminants make this an ideal textbook for a graduate or upper-level undergraduate course on occupational exposure assessment of airborne contaminants.
