Overview
During problem formulation, the IRIS Program was looking for input from the scientific community and the general public as it frames the specific scientific questions for the systematic reviews that it will conduct to develop the assessments.
Background
History/Chronology
| Date | Description |
|---|---|
| 1988 | EPA published the IRIS Health Hazard Assessment for Inorganic Arsenic. |
| 1999 | NRC reviewed the 1988 IRIS assessment and the available health data for inorganic arsenic and made recommendations for updating the cancer assessment in Arsenic in Drinking Water. |
| 2001 | NRC updated the NRC (1999) report and evaluated the toxicological risk and health effects of arsenic as relevant to the 2001 Arsenic Rule in Arsenic in Drinking Water – 2001 Update. Also in 2001, the NRC reviewed the 2001 Primary Drinking Water Standard for inorganic Arsenic and made recommendations for applying epidemiologic data in the cancer health assessment. |
| 2003 | EPA started a reassessment of the IRIS Toxicological Review. |
| Jul 2005 | EPA released the draft IRIS inorganic arsenic assessment in July 2005 for public comment and peer review. |
| Jun 2007 | The Science Advisory Board (SAB) posted a response to the 2005 EPA reassessment of inorganic arsenic (cancer). |
| Oct 2008 | A draft IRIS Toxicological Review for Inorganic Arsenic (cancer) was submitted to OMB for interagency review. |
| Jun 2009 | EPA hosted an interagency science consultation on the draft IRIS Toxicological Review of Inorganic Arsenic. |
| Feb 2010 | EPA released the draft IRIS Toxicological Review for Inorganic Arsenic (cancer) to SAB and simultaneously to the public for review and comment, focusing on EPA’s responses to the SAB (2007) report. |
| Oct 2010 | EPA released the revised draft IRIS inorganic arsenic assessment for public comment and peer review, SAB announced public teleconference to conduct a quality review of the draft report to be held on November 22, 2010. [Federal Register Oct 25, 2010], and SAB completed its review of the draft assessment. |
| 2011 | Congress directed EPA to contract with the National Research Council (NRC) to review the draft assessment. |
| Nov 2012 | EPA released scoping and problem formulation materials for the IRIS assessment of inorganic arsenic for public comment and discussion. |
| Jan 2013 | EPA held a public planning and scoping meeting for development of a new IRIS Toxicological Review of Inorganic Arsenic. |
