SUPPLEMENTARY INFORMATION:

I. Information About IRIS

    EPA's IRIS Program is a human health assessment program that
evaluates quantitative and qualitative risk information on effects that
may result from exposure to chemicals found in the environment. Through
the IRIS Program, EPA provides the highest quality science-based human
health assessments to support the Agency's regulatory activities and
decisions to protect public health. The IRIS database contains
information on chemicals that can be used to support the first two
steps (hazard identification and dose-response evaluation) of the human
health risk assessment process. When supported by available data, IRIS
provides health effects information and toxicity values for health
effects (including cancer and effects other than cancer). Government
and others combine IRIS toxicity values with exposure information to
characterize public health risks of chemicals; this information is then
used to support risk management decisions designed to protect public
health.
