SUPPLEMENTARY INFORMATION:

I. Summary of Information About the Integrated Risk Information System 
(IRIS)

    IRIS is a database that contains information regarding potential 
adverse human health effects 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 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.

II. Workshop Information

    Members of the public may attend the workshop as observers, and 
there will be a limited time for comments from the public. If you wish 
to make oral comments during the review, you must pre-register at 
http://www.orau.gov/nitrobenze by May 1, 2007. Space is limited and 

reservations will be accepted on a first-come, first-served basis.
