The RfD for chromium (III) is 1.5 mg/kg/d based on the exposure level at which no effects were observed in rats exposed to chromium (III) in the diet. (8) EPA has low confidence in the RfD based on low confidence in the study on which the RfD for chromium (III) was based due to the lack of explicit detail on study protocol and results; and low
Oral Chromium Exposure and Toxicity PubMed Central
Source of oral exposure. However there is no specific drinking water standard for hexavalent chromium. The California public health goal for Cr (VI) is 0.02 ppb which is a very low level and is often exceeded in public drinking water.
It is important to realize hexavalent chromium has its own threshold limit value (TLV) that may be lower than other components present as airborne contaminants. Remember that hexavalent chromium is usually only a percentage of the dust fume and mist generated, and other processes will produce fume containing small amounts of hexavalent chromium.
