SUPPLEMENTARY INFORMATION:
I. Information About 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.
