If food or water is contaminated with high concentrations of hexavalent chromium irritation to the lining of the stomach and intestine, and damage to the male reproductive system may occur. Humans can be exposed to chromium via inhalation, ingestion or skin contact. Although we strive to deliver accurate and up-to-date information, no guarantee to that effect is made. Thatcher earned a Bachelor of Science in biomedical engineering from Mercer University before starting medical research and receiving her doctorate in molecular biology from Vanderbilt University. You should take precautions to prevent exposure to hexavalent chromium in liquid form and to minimize exposure to skin and eyes when working with hexavalent chromium. While some less toxic forms of chromium occur naturally in the environment (soil, rocks, dust, plants, and animals), Cr6 is mainly produced by industrial processes. Hexavalent chromium is considered a general carcinogen 1. Some employees may also be allergic to the compound, which leads to asthma symptoms, such as wheezing or shortness of breath. Hexavalent chromium may exist in aquatic media as water soluble complex anions and may persist in water (Callahan et al., 1979). It is a hard and brittle metal and a trace mineral that the body needs in small amounts to function at its best. Hexavalent chromium causes an allergy known as occupational asthma. Suksomboon N, Poolsup N, Yuwanakorn A. Chromium is a heavy metal that is of high value due to its hardness and high corrosion resistance. Since there is not a method to definitely diagnose cancer caused uniquely by hexavalent chromium exposure, there may be other more prevalent forms of cancer not yet attributed to hexavalent chromium. 2010;16(3):291-9. doi:10.1089/acm.2009.0286. Cr(VI) is considerably more toxic than Cr(III). Since there are 1000 micrograms in a milligram, this value may also be written as 0.005 mg/m 3. Exposure could happen through the mouth, excessive inhalation, or through the skin after contact. Eventually, kidney and liver failure is possible with prolonged exposure to hexavalent chromium. Chromium is an odorless and tasteless metallic element that is found in the earth’s crust. Poisoning is especially pronounced when organisms come into contact with hexavalent chromium, including its compounds, due to its high levels of toxicity. There are several ways through which exposure can be curbed. Hexavalent chromium, also known as chromium 6 (Cr6), is the toxic form of the metal chromium. Our team periodically reviews articles in order to ensure content quality. What Are The Effects Of Chromium Poisoning? Your kidneys and liver will attempt to filter toxins from your body. Prolonged exposure simply allowed hexavalent chromium to accumulate in cells and move to the blood stream to be taken throughout the body.

There are two types: the biologically active type found in foods called trivalent (chromium 3+) and the toxic and unsafe type used in industrial applications called hexavalent (chromium 6+). Hexavalent chromium is a carcinogen and a reproductive toxicant for both males and females. SYMPTOMS: Breathing hexavalent chromium can cause irritation to the lining of the nose, nose ulcers, runny nose, and breathing problems, such as asthma, cough, shortness of breath, or wheezing. Even then, too much of these essential forms of chromium may, hypothetically, lead to genotoxicity. It is also found in air, water, soil, and food. Exposure could happen through the mouth, excessive inhalation, or through the skin after contact. The CDC has a comprehensive website that illustrates this troubling affect.
