National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Utility of Biomarkers as Exposure and Dose Measures.

PB2005105199

Publication Date	2001
Personal Author	Symanski, E.
Page Count	24
Abstract	This study examined variation in the levels of biological measures of exposure to workplace contaminants. Although intra- and inter-individual differences have been characterized for a large number of airborne exposures across occupational groups, similar variation had not been investigated extensively for biological measures. A primary objective of this study was to compile a database of repeated biological measures so that the within- and between-worker sources of variability could be partitioned for as wide a range of biomarkers as possible. Following a review of the world's published literature, biological monitoring data were abstracted from 52 studies that examined workers' exposures to metals, solvents, polycyclic aromatic hydrocarbons, and pesticides. Forty-four percent of the studies also reported personal sampling results, which were compiled as well. Over 4,000 measurements collected on 577 workers in 55 workplaces are contained in the biological database, which represents a wide range of biomarkers collected in blood, urine, and exhaled air.
