Tom Davis, President of Tonka Water, is quoted saying, “Chromex is a method of ion exchange that uses a strong base ion resin. Hexavalent Chromium (also known as Chrome 6 and CrVI) is an human carcinogen that can be dangerous. Cr(VI) is known to cause cancer. Hexavalent chromium is a toxic form of the element chromium. One form is necessary for good health, a second form, trivalent chromium, is relatively benign, and a third form, hexavalent chromium, also known as chromium 6, is a dangerous carcinogen. Revised IDLH: 25 mg Cr(III)/m 3 Basis for revised IDLH: No inhalation toxicity data are available on which to base an IDLH for chromium(III) compounds. Chromium 6 compounds may also cause cancers of the nose and nasal sinuses. During the welding process, chromium is converted to its hexavalent state, Chromium (VI). I have recently become interested in purchasing some pastels, but I realized they contain a chemical called "Hexavalent chromium" or "chromium-6". Chromium-6 is recognized as a human carcinogen when it is inhaled. Hexavalent chromium is a toxic chemical that can cause cancer and damage to the nose, throat, and lungs of workers. In an in vitro study the coordination of chromium by picolinate ligands made chromium picolinate more toxic to cultured cells, leading to enhanced apoptosis [27]. It can cause cells to mutate, increasing the likelihood of the development of some cancers. Stainless steel is highly corrosion resistant. When a chromium compound participates in one of these reactions and the compound loses six electrons, it becomes hexavalent chromium, also known as chromium (VI) – and is now toxic. It can also cause dermatitis and severe irritation to the eyes. A. Hexavalent chromium, also known as chromium 6, is a heavy metal that is commonly found at low levels in drinking water. Hexavalent chromium is water soluble, toxic, and carcinogenic, and is considered a pollutant by the United States Environmental Protection Agency (EPA) . Chronic inhalation of chromium-6 has been shown to increase the risk of lung cancer and … One of the most dangerous contaminants, especially for Maryland residents, is hexavalent chromium (AKA chromium 6). Hexavalent chromium shows up in predominantly three forms: 1) Trivalent Chromium, which occurs naturally as chrome ore and is also an essential nutrient for proper metabolism; 2) Metallic or Elemental Chromium, typically found in aerospace alloys; and 3) Hexavalent Chromium, typically from industrial processes like welding and thermal spray. The ROI of Mitigating Hexavalent Chromium Exposure. OSHA Standards. I was wondering if this actually poses a threat to my well-being, considering there is a page about it here. This heavy metal was the subject of the classic movie “Erin Brockovich,” starring Julia Roberts. Hexavalent chromium is a dangerous chemical. The hexavalent chromium regulation went into effect on May 31, 2010. Depending on the site of exposure, the results can be skin damage, stomach and intestinal injury, or lung damage and eventually lung and kidney cancer. Chromium is a naturally occurring element found in rocks, animals, plants, soil, and in volcanic dust and gases. (1) Chromium occurs in the environment predominantly in one of two valence states: trivalent chromium (Cr III), which occurs naturally and is an essential nutrient, and hexavalent chromium … As a result, the lab had to redraw the shape of the plume. Skin exposure can occur during direct handling of hexavalent chromium-containing solutions, coatings, and cements. Goldman said the holdup over setting a federal regulation for chromium-6 is likely due to the fact that testing for chromium-6 toxicity is difficult and few people have proper experience with it. Hexavalent chromium compounds are man-made and widely used in many different industries. P.S. Hello! Although chromium hexavalent is dangerous and toxic, it’s useful in industrial applications. Extremely high levels of intake of chromium-3, however, can have potentially dangerous side effects.
