Excessive amounts of cobalt can lead to metal poisoning. There is conflicting evidence on whether there is a correlation between higher cobalt and chromium concentrations and systemic toxicity. Cobalt is needed in most animals and humans to remain healthy; however, it is only needed in tiny amounts. Human body contains cobalt in the amount of less than one mg, of which 0.36 mg contained in the adipose, 0.3 mg - in the hair, 0.28 mg - in the bones, and 0.2 mg - in the muscles, 0.11 mg - in the liver. Case of cobalt poisoning. Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Cobalt. Some patients have also reported heart failure, loss of vision, loss of hearing, and organ damage. The effects of the cobalt alloy hips were life-altering for Frances. Industrial plants may leak cobalt and other toxic metals into the environment. Signs and Symptoms: Acute Exposure. Cobalt is a component of vitamin B12, which supports the production of red blood cells. Schirrmacher UO. Cobalt is not highly toxic, but large doses will produce adverse clinical manifestations. Cobalt deficiency that is related to vitamin B12 deficiency is a cause of pernicious anaemia. It induces the production of thyroid hormones. Leyssens L, Vinck B, Van Der Straeten C, Wuyts F, Maes L. Cobalt toxicity in humans-A review of the potential sources and systemic health effects. Metal poisoning is a very serious and detrimental illness, wreaking havoc on several systems in the body. In: Aronson JK, ed. Course: WB 1095 CE Original Date: May 23, 2008 … However, cobalt in air will var y substantially from non-source areas to areas with cobalt-related industries. The oral bioavailability of inorganic cobalt varies with the solubility of the cobalt compound (5–45%). Cobalt can accumulate to toxic levels in the liver, kidney, pancreas, and heart, as well as the skeleton and skeletal muscle. 7. In experimental studies where cobalt alone exerted minimal adverse cardiac effects, the toxicity of cobalt became manifest in the presence of hypothyroidism or by the consumption of a low-protein, low-thiamine diet. Cobalt salts are also used in the glass and pigment industry. Cobalt has been found to produce tumors in animals and is likely a human carcinogen as well. Because cobalt-60 is absorbed by the livers, kidneys and bone tissues, it can compromise the functions of these organs. Meyler's Side Effects of Drugs. BMJ 1967; 1: 544-545. In more recent years, several cases of cobalt toxicity have been related to cobalt containing implants used in joint arthroplasty, especially in those with overt prosthetic failure or resurfacing of the MoM THA [ 1 ]. INTRODUCTION: There have been concerns about prosthesis failure and the potential for systemic toxicity due to release of cobalt and chromium from metal-on-metal hip joint prostheses (MoM-HP). Studies on both animals and humans have shown that toxicity can happen in all organs of the body with exposure to non-radioactive cobalt. Cobalt toxicity also has been described after industrial exposure to cobalt, as well as iatrogenic toxicity following treatment of anaemia with cobalt-chloride tablets [1, 2]. J Bone Joint Surg Br 2007; 89: 567-573. Severe exposures to Cr(VI) compounds are usually accidental or intentional (suicide), and are rarely occupational or environmental. The average concentration of cobalt in ambient air in the USA is approximately 0.4 ng /m 3. Over time, the condition also leads to decreased nerve function. Acute poisoning is likely to occur through the oral route, whereas chronic poisoning is mainly from inhalation or skin contact [Meditext 2005].
