Bill would require a specific federal limit for chromium-6
California Sens. Dianne Feinstein and Barbara Boxer introduced a bill that would require the U.S. Environmental Protection Agency (EPA) to set a federal limit for chromium-6, a potentially cancer-causing chemical, The Sun reported. Currently, EPA has a limit for total chromium, which includes chromium-6, chromium-3 and chromium-0. The bill, which was introduced Jan. 25, would require EPA to set a new limit specifically for chromium-6 within one year of its passage.
