Biomonitoring Data

Biomonitoring is the direct measurement of people’s exposure to toxic substances by measuring the substances or their metabolites in human specimens, such as blood or urine. Biomonitoring measurements provide health-relevant assessments of exposure because they indicate the combined amount of the chemical that actually gets into people from all environmental sources (for example, air, soil, water, dust, food). Biomonitoring efforts help individuals determine the types of environmental chemicals that people have been exposed to, the amount of those chemicals that actually gets into their bodies, and the concentrations of chemicals in their bodies that may be related to adverse health effects. Water-related biomonitoring data and statistics are highlighted below.
