Hexavalent chromium and its compounds are toxic when inhaled or ingested. Trivalent chromium is a trace mineral that is essential to human nutrition. There is a hypothetical risk of genotoxicity in humans if large amounts of trivalent chromium were somehow able to enter living cells, but normal metabolism and cell function prevent this. [2]
Historically, the therapeutic dose of bromide is about 3 to 5 grams of bromide, thus explaining why chronic toxicity (bromism) was once so common. While significant and sometimes serious disturbances occur to neurologic, psychiatric, dermatological, and gastrointestinal functions, death is rare from bromism.
This study looks at chronic oral exposure of hexavalent chromium in rats, and its association with cancer. The other study mentioned is a human health assessment of chromium, titled Toxicological Review of Hexavalent Chromium. The final human health assessment is currently in the stage of draft development. [47] This stage is the first of seven.
Chromium-6 is fairly rapidly converted to the less toxic chromium-3 in the stomach.” The FDA said it is advising parents with children impacted by the recall to inform their health care provider.
There is little evidence that trivalent chromium in typical supplement amounts causes toxicity in humans. [2] Oral use of chromium is considered to be relatively safe because ingested chromium is poorly absorbed and the amount absorbed is rapidly excreted. [2] Use of chromium picolinate may cause an allergic reaction, headache, insomnia, or ...
California has set a limit for the toxic heavy metal hexavalent chromium in drinking water. Advocates have called for a stricter limit, warning of health risks.
Chromium supplementation in general is subject to a certain amount of controversy as it is by no means clear that chromium is an essential element in human biology. [25] Nevertheless, chromium is an ingredient in total parenteral nutrition, along with other trace minerals. [26] It is also in nutritional products for preterm infants. [27]
Chromium, especially hexavalent chromium, is highly toxic to fish because it is easily absorbed across the gills, readily enters blood circulation, crosses cell membranes and bioconcentrates up the food chain. In contrast, the toxicity of trivalent chromium is very low, attributed to poor membrane permeability and little biomagnification. [141]
