testing for the presence of a hazardous substance, its metabolites or a biochemical change in a person’s body tissue, exhaled air or fluid.
Measuring chemicals in biological materials (blood, urine, breath, etc.) to determine whether chemical exposure in humans, animals, or plants has occurred.
Analyzing chemicals, hormone levels or other substances in biological materials (blood, urine, breath, etc.) as a measure of chemical exposure, health status, etc. in humans or animals. A blood test for lead is an example of biological monitoring.
A tool used to assess environmental or occupational exposures and involving the analysis of appropriate bodily fluids (e.g., blood, urine, exhaled breath) or tissues and comparing the results with guideline values such as maximum acceptable concentrations (MACs) or biological exposure indices (BEIs).
the measurement and assessment of levels of chemicals or their metabolites (substances the body converts the chemical into) in the breath, urine or blood (or any combination of these) of exposed workers. This monitoring may investigate either the level of systemic exposure to an active substance or look for chemical signs of a reaction to exposure.
Measurement of toxic agents or the results of their metabolism in biological materials, such as blood, urine, expired air, or biopsied tissue, to test for exposure to toxic agents or the detection of physiological changes due to exposure.
The use of a biological entity as a detector and its response as a measure to determine environmental conditions. Toxicity tests and biological surveys are common biomonitoring methods (USEPA Region 5).
Continuous or repeated measurement of potentially toxic substances or their metabolites or biochemical effects in tissues, secreta, excreta, expired air or any combination of these in order to evaluate occupational or environmental exposure and health risk by comparison with appropriate reference values based on knowledge of the probable relationship between ambient exposure and resultant adverse health effects. NT biological effect monitoring BT environmental monitoring, monitoring. RT biological assessment of exposure.
The chemical analysis of chemicals or metabolites, or both, from a worker's blood, urine, fingernails, sweat, breath, etc.
