Biomonitoring is the direct measurement of chemicals in people's bodies. It measures environmental chemicals or their breakdown products (metabolites) in human specimens such as blood and urine. You can find environmental chemicals in air, water, food, soil, dust, and consumer products. Biomonitoring data gives us information on the total amount of environmental chemicals that get into the body from all possible sources.
Why is biomonitoring data important?
Biomonitoring data is often used to help study and assess:
- Background exposures in a population
- Changes in human exposures over time
- Effectiveness of prevention activities
- Differences in exposures between populations
- Exposure-related health problems
