Cobalt | NIOSH | CDC

24/06/2019· Cobalt (Co) is a hard, gray metal that occurs naturally. It is found in rocks, soil, water, plants, and animals, including people. It can harm the eyes, skin, heart, and lungs. Exposure to cobalt may cause cancer. Workers may be harmed from exposure to cobalt and cobalt-containing products. The level of harm depends upon the dose, duration, and work being done.Cobalt poisoning: MedlinePlus Medical Encyclopedia,Cobalt poisoning can also occur from the wear and tear of some cobalt/chromium metal-on-metal hip implants. This type of implant is an artificial hip socket that is created by fitting a metal ball into a metal cup. Sometimes, metal particles (cobalt) are released as the metal ball grinds against the metal cup when you walk. These metal,Cobalt-Related Exposures Cobalt and Cobalt Compounds That,,balt sulfate and one study with cobalt chloride), and poorly water-soluble cobalt compounds (four studies with cobalt oxide). Studies of cobalt alloys and radioactive cobalt in experimental animals were not considered to be informative, because of potential confounding by other carcinogens. Inhalation exposure of rats and mice to cobalt metal,

Toxic Metal: The Health Dangers of Cobalt

Cobalt Exposure. Industrial plants may leak cobalt and other toxic metals into the environment. Once cobalt particles enter the atmosphere, they settle to the ground and enter the food and water supply; most of the population is exposed to cobalt through food, water, and air. Cobalt makes its way through the environment and cannot be destroyed,Cobalt and Carcinogenicity | Cobalt Institute,Cobalt is an inhalation carcinogen in rats and mice. Two chronic lifetime inhalation studies have determined that cobalt, at high exposure levels, can cause lung cancer in rodents. These studies were conducted by the US NTP using rats and mice to investigate inhalation exposure to cobalt sulphate heptahydrate and cobalt metal powder [10]. In,Exposure to Cobalt Causes,- PubMed Central (PMC),Using mass spectrometry, we identified intracellular proteins changing in abundance after exposure to cobalt chloride in MH1C1 cells. We examined the high concentration of the MH1C1 cells since this dose and cell line had the greatest effect with regard to gene expression changes, which allowed us to identify a large number of proteins changing,
