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.
