potassium dichromate poisoning
Poisoning is a rare complication of NFB insertion. A fatal case of potassium dichromate ingestion is documented. The toxicity of Cr6+ (as Cr2O7(2-)) was found to be due to its specific antagonism of sulfate uptake. We report a very rare case of survival after accidental Cr poisoning which has an extremely poor prognosis and usually leads to rapid death. Lung cancer risk in relation to airborne levels of Cr(VI) was analyzed for chromium chemical production workers and a dose-response relationship was observed in that long-term workers had a higher lung cancer risk than short-term workers [Hayes, Lilienfeld et al. In an industrial hygiene survey of 60 ferrochromium workers exposed to Cr(III) and Cr(VI) (0.02-0.19 mg total chromium/m³) conducted in 1975, appreciably higher incidences of subjective symptoms of coughing, wheezing, and dyspnea were reported compared with controls. Occupational exposure to Cr(VI) compounds in a number of industries has been associated with increased risk of respiratory system cancers. Five plasmapheresis treatment sessions significantly lowered his serum and urinary chromium concentrations. However, due to its toxicity, you should limit your exposure to potassium chromate. The reported liver effects include derangement of the liver cells, necrosis, lymphocytic and histocytic infiltration, and increases in Kupffer cells [Pascale, Waldstein et al. Eyes Irritation, redness, watering eyes, itchiness, possible loss of vision, transient corneal bulging, residual irregular astigmatism, and anesthesia of … In a chrome plating plant where poor exhaust resulted in excessively high concentration of chromium trioxide fumes, workers experienced symptoms of dizziness, headache, and weakness when working over the chromate tanks [Lieberman 1941]. 1979]. It is highly toxic compound which normally proves fatal when ingested orally as its fatal dose is very small. Ltd. M: Sco 3-4, Chowk Gurudwara Dukhniwaran Sahib, Sirhind Road, Patiala-147001 (Punjab) India, 0175-2357981, 98146-32807, 93165-23260, 9888188887, Potassium dichromate is commonly used chemical in various industrial and laboratory, with suicidal intention. Cr(VI) enters many types of cells and under physiological conditions can be reduced by hydrogen peroxide (H2O2), glutathione (GSH) reductase, ascorbic acid, and GSH to produce reactive intermediates, including Cr(V), Cr(IV), thiylradicals, hydroxyl radicals, and ultimately, Cr(III). D. Its skin sensitizing effect. Exposure to Cr(III) has not been found to cause any liver effects in workers employed in two factories that produced Cr(III) oxide or Cr(III) sulfate [Korallus, Ehrlicher et al. 1994] and hepatic failure [Loubieres, de Lassence et al. The toxicity of chromium within the cell may result from damage to cellular components during the hexavalent to trivalent chromium reduction process, by generation of free radicals, including DNA damage [ATSDR 2000]. Major factors governing the toxicity of chromium compounds are oxidation state and solubility. Evidence revealed that there was a significant difference (p â¤ 0.05) in the toxicity and teratogenicity of the selected indigenous spices against zebrafish embryo/larvae as evidenced by less hatchability, morphological abnormalities, and high mortality.

One study showed wives of stainless steel welders were at higher risk of spontaneous abortions [Bonde, Olsen et al.

Once ingested, it causes gastrointestinal injury first and then is rapidly absorbed and taken up by various tissues of the body where it generates reactive intermediates and oxygen free radicals that damage various intracellular components especially in renal tubules, hapatocytes, RBCs and platelets. 1990; Cohen, Kargacin et al. Since Cr(III) is poorly absorbed by any route, the toxicity of chromium is mainly attributable to the Cr(VI) form. A ring test involving 129 EC50 determinations from 46 laboratories determined the mean 24h-EC50 value as 1.5 mg K2Cr2O7/l (EEC, 1992).
