Contact the IRIS Webmaster

The Integrated Risk Information System (IRIS) Program provides information on the health effects of chemicals, and IRIS assessments include information about health hazards as well as toxicity values that can be used in human health risk assessment. The IRIS Webmaster provides technical (web) support only on the IRIS web site and database.  Requests for information on chemicals or for any topic not perceived as a technical issue will not be addressed by this service.

We strive to respond to every request with an answer or an appropriate referral as quickly as possible. Most requests will be responded to within 10 business days. Please submit your question or comment using the form below. Please make sure to include your correct email address if you would like an email response.
