BIOLOGICAL ASSESSMENT OF EXPOSURE Meaning and
Definition
-
The biological assessment of exposure refers to a comprehensive evaluation process that examines the potential impacts or effects of exposure to biological agents or substances on living organisms, including humans and animals. It involves the measurement and analysis of various biological indicators or markers to determine the extent of exposure to these agents and assess their associated risks or hazards.
In the context of occupational or environmental health, the biological assessment of exposure seeks to quantify and evaluate the levels of biological agents in the body, such as infectious microorganisms, toxic chemicals, or hazardous substances. This assessment helps to ascertain the degree of exposure and potential health effects resulting from contact with these agents.
The process typically involves collecting biological samples, like blood, urine, or tissues, from individuals or populations. These samples are then analyzed for the presence and concentration of specific bioindicators, biomarkers, or metabolites of the target agents. This information is compared to established reference values or exposure limits to assess the potential health risks associated with the exposure.
The biological assessment of exposure plays a vital role in risk assessment, as it provides a more accurate and direct measurement of exposure levels and potential health effects than solely relying on environmental or personal exposure monitoring. It enables health professionals, researchers, and policymakers to better understand and manage the risks posed by various biological agents, thereby facilitating the implementation of effective preventive measures and intervention strategies.
