Integrated Risk Information System (IRIS)

US Environmental Protection Agency

This database was developed by the US Environmental Protection Agency in response to a demand for consistent human health risk information on chemicals for use in decision-making and regulatory activities. IRIS contains records for nearly 700 chemicals. In addition to basic information on chemical and physical properties and toxicity, the database is a unique resource for human health assessment information, such as reference doses, carcinogenicity assessments, drinking water health advisories and US EPA regulatory actions.
