The Office of Environmental Health Hazard Assessment proposed amendments to 27 Cal. Code Regs. §25707, Route of Exposure. Changes would remove the reference to hexavalent chromium as posing no significant risk when ingested, based on recent scientific findings that establish that chromium can be carcinogenic by the oral route. The deadline for comment is October 31, 2011. See http://www.oal.ca.gov/res/docs/pdf/notice/37z-2011.pdf (pp. 1505-07).
