Integrated Risk Information System

EPA’s mission is to protect human health and the environment. EPA’s IRIS Program supports this mission by identifying and characterizing the health hazards of chemicals found in the environment.

Each IRIS assessment can cover a chemical, a group of related chemicals, or a complex mixture.
