Biomonitoring

Definition

Biomonitoring is the systematic measurement of biological markers in organisms, including humans, to assess exposure to environmental chemicals and their potential effects on health. This process helps in understanding the relationship between environmental factors and health outcomes by tracking changes in biomarker levels over time, providing insights into pollution exposure, and evaluating the effectiveness of regulatory policies.

5 Must Know Facts For Your Next Test
