The Agency for Toxic Substances and Disease Registry (ATSDR) is a public health agency that is part of the Centers for Disease Control and Prevention (CDC). Its primary function is to assess the health impact of hazardous substances in the environment, and it plays a crucial role in the federal government’s response to environmental health emergencies.

One of the vital responsibilities of the ATSDR is to evaluate exposure to toxic substances and provide information and guidance to protect public health. By being under the umbrella of the CDC, the ATSDR can collaborate on research, education, and prevention strategies related to toxic substances and their effects on human health.

The other organizations listed, such as the FDA, WHO, and NIEHS, have different focuses. The FDA (Food and Drug Administration) regulates food, drugs, and medical devices; the WHO (World Health Organization) focuses on global public health issues; and the NIEHS (National Institute of Environmental Health Sciences) conducts research on environmental health. While all these agencies contribute to public health in various ways, the ATSDR’s specific role concerning toxic substances situates it firmly within the CDC’s framework.
