title: Validity criteria for the use of biological markers of exposure to chemical agents in environmental epidemiology.
abstract: Biomarkers may prove very useful in increasing the precision of exposure estimates during field epidemiological studies of environmental and occupational exposures. However, the determination of validity of exposure biomarkers is a laborious process. It is also a process that needs collaboration between laboratory and field scientists if biological markers of exposure are to be useful tools in environmental epidemiology.
