The Integrated Risk Information System (IRIS) is
a human health assessment program that 
evaluates quantitative and qualitative risk 
information on effects that may result from 
exposure to environmental contaminants. 
IRIS was initially developed for EPA staff in 
response to a growing demand for consistent
 information on substances for use in risk 
assessments, decision-making, and regulatory 
activities. The information in IRIS is intended 
for those without extensive training in 
toxicology, but with some knowledge of health 
sciences.
