SUPPLEMENTARY INFORMATION: 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 550 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 
management decisions designed to protect public health.
