SUPPLEMENTARY INFORMATION:

I. Information About IRIS

    EPA's IRIS is a human health assessment program that evaluates 
quantitative and qualitative risk information on effects that may 
result from exposure to chemical substances 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. The IRIS database contains information for more than 540 
chemical substances that can be used to support the first two steps 
(hazard identification and dose-response evaluation) of the risk 
assessment process. When supported by available data, IRIS provides 
oral reference doses (RfDs) and inhalation reference concentrations 
(RfCs) for chronic noncancer health effects and cancer assessments. 
Combined with specific exposure information, government and private 
entities use IRIS to help characterize public health risks of chemical 
substances in a site-specific situation and thereby support risk
