Monitoring activities have an important role in occupational and environmental practice. Techniques to detect and to control chemical exposure in order to protect people from environmental and occupational illness are rapidly expanding. Most obvious are the methods related to the evaluation of the presence of xenobiotic chemical agents either in the ...

Abstract Biological monitoring is method for assessing chemical exposures by measuring either the chemical substance or its breakdown products in a biological samples e.g. blood, urine. This method of measuring exposure is particularly useful when chemical substances used in occupational setting can be absorbed through the skin or where ...

Occupational medicine (Philadelphia, Pa.), 1990
It is important to distinguish biological from medical or health monitoring because the submission of a biological specimen often leads to the assumption of the part of workers and also health professionals that health effects are being measured, and that measurement exceeding a reference value indicates disease rather than exposure or health risk ...

Biological monitoring of hexachloroethane
International Archives of Occupational and Environmental Health, 1993A small group (n = 12) of military white smoke munition workers provided blood plasma during a production break (S I) and after five weeks' production (S II) of a hexachloroethane (HCE)/titanium dioxide formula. Plasma was also obtained from a sex and age matched control group (n = 12) and a group (n = 13) of previously HCE-exposed workers ...

Biological Monitoring of Nickel
Toxicology and Industrial Health, 1986Measurements of nickel in body fluids, excreta, and tissues from humans with occupational, environmental, and iatrogenic expo sures to nickel compounds are comprehensively reviewed. Correla tions between levels of human exposures to various classes of nickel compounds via inhalation, oral, or parenteral routes and the corresponding concentrations of ...

Monitoring the Biological Aerosol
2003The air of indoor and outdoor environments contains a great number of particles in suspension, having various origins, shapes and sizes. These particles form the atmospheric aerosol (Table 5.1). The criterion for classifying the particles may vary, depending on the purpose of the work: they may be classified on the basis of their nature (biological ...

AbstractThis chapter provides a general introduction to biological monitoring of exposure in occupational and environmental epidemiological studies. It describes models that could be used for the assessment and strategies for biological monitoring, including issues that need to be taken into account. It provides various examples and references.

Biological monitoring of radiation exposure
Advances in Space Research, 1998Complementary to physical dosimetry, biological dosimetry systems have been developed and applied which weight the different components of environmental radiation according to their biological efficacy. They generally give a record of the accumulated exposure of individuals with high sensitivity and specificity for the toxic agent under consideration ...
