ATSDR

ATSDR (Agency for Toxic Substances and Disease Registry) is a U.S. public health organization that studies the effects of hazardous substances on people's health. It works to understand how exposure to chemicals and pollutants in the environment—like contaminated water, soil, or air—can cause health problems. ATSDR also provides guidance to communities, healthcare providers, and policymakers on how to prevent or reduce harmful exposures, ensuring that environmental risks are managed effectively to protect public health.
