Biomonitoring is the assessment of exposure to toxic substances in people by the laboratory measurement of these substances (or their metabolites) in human specimens, such as blood, urine, or saliva. It can be used to establish the body burden or internal dose of specific environmental contaminants through all routes of exposure. Population-based biomonitoring, in combination with environmental monitoring (e.g. of air, dust, water, food, and soil), can provide detailed information about differences in exposures across geography, race/ethnicity, and socio-economic status. Biological monitoring can also illuminate the relationships between genetic predispositions or sensitivities and disease outcomes.

EHIB uses biomonitoring in studies linking environmental exposures and pollution-related diseases, for environmental health tracking and to explore body burdens in populations that may be at increased risk from exposure.
