IRIS

This page provides a description and a link to a "IRIS" database that provides information needed when modeling exposure levels or performing exposure assessment.

Short description

IRIS is a database of human health effects that may result from exposure to various substances found in the environment. The heart of the IRIS system is its collection of computer files covering individual chemicals. These chemical files contain descriptive and quantitative information in the following categories: a) Oral reference doses and inhalation reference concentrations (RfDs and RfCs, respectively) for chronic noncarcinogenic health effects, b) Hazard identification, oral slope factors, and oral and inhalation unit risks for carcinogenic effects. Database includes over 500 chemicals.

Data scrapping

IRIS database is accessible from this link: http://cfpub.epa.gov/ncea/iris/compare.cfm. The critical data can be obtained at once if all substances and all types of data are selected. A result is an html file with several tables from which the data can be scrapped and transformed into a better format. The January 4th, 2012, version was downloaded from IRIS and saved on this page (see the file below). Who could do this?

Reference system in IRIS database. The number (e.g. 0442) refers to the IRIS chemical identifier.
