  • About the Program
    The Centers for Disease Control and Prevention's (CDC) Health Studies Program investigates the human health effects of exposure to environmental hazards ranging from chemical pollutants to natural, technologic, or terrorist disasters.

  • Chemicals
    The release of a chemical weapon of mass destruction (WMD) could result in hundreds or thousands of casualties, and the source of the release likely would be obvious to public health officials. However, the source of an accidental chemical release, or the hidden, intentional contamination of food or drinking water, would be more difficult to identify. Various programs at CDC work to detect, respond to, and prevent human illness caused by a chemical release ...more
  • Concentrated Animal Feeding Operations (CAFOs)
    Concentrated animal feeding operations (CAFOs) are agricultural facilities that house and feed a large number of animals in a confined area for 45 days or more during any 12-month period. CDC is working with states to define routes of exposure and potential human health effects from exposures to wastes and residues from confined animal feeding operations ...more

  • Pesticides
    Human exposure to pesticides occurs primarily through dietary residues, outdoor pesticide exposure (gardening and lawn applications), indoor pesticide exposure (including tracking in outdoor pesticides), occupational exposures (pest control applicators and farm workers), and the use of pesticides on domestic animals, including pets. Exposure to pesticides that results from natural disasters or terrorism also poses a threat to public health ...more
