Dear all,

How does the California action fit in with the US EPA's recently issued consultation on Cr VI?

On 30 September 2010, the USEPA published a draft toxicological review for hexavalent chromium and announced a 60 day public comment period (which was extended to 29 December 2010. The review concluded:

"hexavalent chromium is 'likely to be carcinogenic to humans' via the oral route of exposure based on a statistically significant increase in the incidence of tumors of the oral mucosa and tongue of rats  and of the small intestine of mice, and evidence of an association between oral exposure to hexavalent chromium and stomach cancer in humans. Additionally, available evidence indicates that chromium interacts with DNA, resulting in DNA damage and mutagenesis.  Based on the weight of the available evidence, hexavalent chromium is proposed to act through a mutagenic mode of carcinogenic action ..."
