Environmental Chemicals

Photo of farm tractor spraying crops CDC's National Biomonitoring Program (NBP) determines which environmental chemicals people have been exposed to and the amount of those chemicals in their bodies.

Environmental chemicals refer to a chemical compound or chemical element present in air, water, food, soil, dust, or other environmental media such as consumer products.

Currently, more than 300 environmental chemicals or their metabolites are measured in human samples (e.g. urine, blood, serum, breast milk, and meconium). CDC's National Biomonitoring Program provides information on human health effects, national surveillance data, and additional learning resources for each chemical and chemical group studied.
