CDC & Environmental Toxins

"The Agency for Toxic Substances and Disease Registry (ATSDR), based in Atlanta, Georgia, is a federal public health agency of the U.S. Department of Health and Human Services. ATSDR protects communities from harmful health effects related to exposure to natural and man-made hazardous substances. We do this by responding to environmental health emergencies; investigating emerging environmental health threats; conducting research on the health impacts of hazardous waste sites; and building capabilities of and providing actionable guidance to state and local health partners."

"CDC has developed specific and sensitive methods to help diagnose, treat, and prevent diseases caused by toxins. Toxins from bacteria, fungi, algae, and plants are some of the most deadly chemicals known and represent an ongoing public health threat."

"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 400 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."

"CDC’s Division of Laboratory Sciences (DLS) and National Biomonitoring Program (NBP) provide effective laboratory support for the public health response to chemical threat agents and threats involving selected toxins.

Chemical threat agents can be poisonous vapors, aerosols, liquids or solids that have toxic effects on people. These chemicals can be naturally occurring in the environment or synthetically produced."

"The measurement of an environmental chemical in a person’s blood or urine does not mean, by itself, that the chemical causes disease or adverse effects. Advances in analytical methods allow us to measure lower and lower levels of environmental chemicals in people."
