On September 5, 2008, the Office of Environmental Health Hazard Assessment (OEHHA) released for public review and comment hazard identification materials on the chemical chlorpyifos. Chlorpyrifos will come before the Developmental and Reproductive Toxicant Identification Committee on November 20, 2008, for the Committee to determine if it should be added to the Proposition 65 list of chemicals known to the State to cause reproductive toxicity.
A U.S. Environmental Protection Agency Issue Paper on the Toxicity Profile of Chlorpyrifos was released on August 27, 2008. Appendix D: Human Epidemiology: Effects in Children of that paper includes relevant data and analyses conducted by the original researchers after discussion with U.S. EPA and not available elsewhere. In order to provide the Committee with access to those data and analyses, a copy of the Issue Paper is being sent to the Committee.
The Issue Paper on the Toxicity Profile of Chlorpyrifos can be accessed at http://www.epa.gov/scipoly/sap/meetings/2008/091608_mtg.htm#frn, or can be obtained from the Proposition 65 Implementation Office by calling (916) 445-6900.
