ATSDR works in, with, and for communities to protect them from potential harmful health effects related to exposure to natural and man-made hazardous substances found in the environment.

The Agency for Toxic Substances and Disease Registry (ATSDR) serves as a science-based public health agency working to address community concerns about hazardous substances. We work in communities to assess human exposure to potentially harmful contaminants in the environment and their effect on health, and we provide expertise to educate and train communities so they can take action to protect their health. ATSDR works with federal, state, and local governments to

  • Identify environmental hazards
  • Respond to environmental health emergencies
  • Recommend actions to reduce environmental exposures and respond to questions about exposures
  • Provide guidance to healthcare providers
  • Conduct research on the health impacts of hazardous substances in the environment and build capacity of state, tribal, and local health partners
