Biomonitoring is the assessment of exposure to toxic substances in people by 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, or 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.
The purpose of the California Environmental Contaminant Biomonitoring Program, also called Biomonitoring California, is to:
1. Determine levels of environmental chemicals in a representative sample of Californians.
2. Establish trends in the levels of these chemicals over time.
3. Help assess the effectiveness of public health efforts and regulatory programs to decrease exposures to specific chemicals.

About Biomonitoring California
The California Environmental Contaminant Biomonitoring Program was established by Senate Bill 1379, authored by Senator Don Perata and Senator Deborah Ortiz, which was passed by the California Legislature and signed into law by Governor Schwarzenegger in 2006.
Biomonitoring California is a collaborative effort of three departments in two State agencies:
· The California Department of Public Health (CDPH, www.cdph.ca.gov) in the Health and Human Services Agency. CDPH is the lead department for Biomonitoring California.
· California Environmental Protection Agency’s (Cal/EPA’s) Office of Environmental Health Hazard Assessment (OEHHA, www.oehha.ca.gov) and Department of Toxic Substances Control (DTSC, www.dtsc.ca.gov).
Biomonitoring California acknowledges crucial support from the Centers for Disease Control and Prevention (Cooperative Agreement Number 5U38EH000481) from 2009 to 2014.
The California Environmental Health Tracking Program of EHIB has also undertaken biomonitoring activities and is interested in examining exposure to contaminants in communities that have the potential to be highly exposed
