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.
