Chromium toxicity refers to any poisonous toxic effect in an organism or cell that results from exposure to specific forms of chromium—especially hexavalent chromium. [1] Hexavalent chromium and its compounds are toxic when inhaled or ingested. Trivalent chromium is a trace mineral that is essential to human nutrition.
Hexavalent chromium pollution in Greece is associated with industrial waste. By using the GFAAS for total chromium, diphenylcarbazide-Cr(VI) complex colorimetric method for hexavalent chromium, and flame-AAS and ICP-MS for other toxic elements, their concentrations were investigated in several groundwater samples. The contamination of water by ...
Exposure to hexavalent chromium can cause irritation and problems in the respiratory tract, stomach, and small intestine. It is linked to several cancers, such as lung cancer, oral cancer, and intestinal cancer. [11] During floods, the chromium contaminated groundwater would flood into local Garfield residences and businesses.
Children who consumed the recalled lead-contaminated WanaBana cinnamon applesauce pouches may also have been exposed to the heavy metal chromium, the Food and Drug Administration said Friday.. The ...
PG&E used chromium 6, or hexavalent chromium (a cheap and efficient rust suppressor), in its compressor station for natural-gas transmission pipelines. [1] [3] Hexavalent-chromium compounds are genotoxic carcinogens. In 1993, legal clerk Erin Brockovich began an investigation into the health impacts of the contamination. A class-action lawsuit ...
In June 2009, Brockovich began investigating a case of contaminated water in Midland, Texas. [26] "Significant amounts" of hexavalent chromium were found in the water of more than 40 homes in the area, some of which have now been fitted with state-monitored filters on their water supply. [26]
Chromium(VI) (Hexavalent chromium) compounds [note 2] Ciclosporin; Cyclophosphamide; 1,2-Dichloropropane; Diethylstilboestrol; Erionite; Ethanol in alcoholic beverages [4] Ethylene oxide; Etoposide alone, and in combination with cisplatin and bleomycin; Fluoro-edenite fibrous amphibole; Formaldehyde; Gallium arsenide; Lindane; Melphalan
Levels of chromium toxicity, mobility and bioavailability depend on oxidation states of chromium. [14] Two of the most common chromium species are Cr(III) and Cr(VI). Cr(VI) is highly mobile, bioavailable and more toxic to flora and fauna , while Cr(III) is less toxic, more immobile and readily precipitates in soils with pH >6. [ 15 ]
