SUPPLEMENTARY INFORMATION:

I. Summary of Information About the Integrated Risk Information System 
(IRIS)

    IRIS is a database that contains potential adverse human health 
effects information that may result from chronic (or lifetime) exposure 
to specific chemical substances found in the environment. The database 
(available on the Internet at http://www.epa.gov/iris) contains 
qualitative and quantitative health effects information for more than 
540 chemical substances that may be used to support the first two steps 
(hazard identification and dose-response evaluation) of a risk 
assessment process. When supported by available data, the database 
provides oral reference doses (RfDs) and inhalation reference 
concentrations (RfCs) for chronic health effects, and oral slope 
factors and inhalation unit risks for carcinogenic effects. Combined 
with specific exposure information, government and private entities can 
use IRIS data to help characterize public health risks of chemical 
substances in a site-specific situation and thereby support risk 
management decisions designed to protect public health.
