harp -- The updated Consolidated Table of Risk Assessment Health Values is now available
Posted: 15 Feb 2011 14:16:30
The updated Consolidated Table of OEHHA / ARB Approved Risk Assessment Health Values is now available. The updated Consolidated Table can be downloaded at http://www.arb.ca.gov/toxics/healthval/healthval.htm. This table contains updated health values for polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs). The new health values have been revised to reflect the Office of Environmental Health Hazard Assessment‘s adoption of the World Health Organization’s 2005 Toxicity Equivalency Factors for PCDDs, PCDFs, and dioxin-like PCBs. See Appendix C of OEHHA’s Air Toxics Hot Spots Program Technical Support Document for Cancer Potencies at http://www.oehha.ca.gov/air/hot_spots/pdf/AppCdioxinTEFs013111.pdf for more information.
