Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Cobalt is an essential element for health in animals in minute amounts as a component of vitamin B 12 . A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia .
The cobalt atoms are formally in the +3 oxidation state, hence the IUPAC name lithium cobalt(III) oxide. Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid, [ 4 ] and is commonly used in the positive electrodes of lithium-ion batteries .
Lithium toxicity, also known as lithium overdose, is the condition of having too much lithium. Symptoms may include a tremor, increased reflexes, trouble walking, kidney problems, and an altered level of consciousness. Some symptoms may last for a year after levels return to normal. Complications may include serotonin syndrome. [1]
Generally, increased exposure to heavy metals in the environment increases risk of developing cancer. [37] Without a diagnosis of metal toxicity and outside of evidence-based medicine, but perhaps because of worry about metal toxicity, some people seek chelation therapy to treat autism, cardiovascular disease, Alzheimer's disease, or any sort ...
The following is a list of chemicals published as a requirement of Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as California Proposition 65, that are "known to the state to cause cancer or reproductive toxicity" as of January 3, 2020. [1]
During chronic toxicity, the gastrointestinal symptoms seen in acute toxicity are less prominent. The symptoms are often vague and nonspecific. [106] If the lithium toxicity is mild or moderate, lithium dosage is reduced or stopped entirely. If the toxicity is severe, lithium may need to be removed from the body.
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
In 1974, Axt calibrated a cobalt-60 teletherapy unit with an incorrect decay curve. The calculated decay rate was more rapid than the real source, leading to a dose rate underestimated by 10–45% and an overestimated treatment time. [2] [3] No other calibrations and checks were performed between May 1974 and January 1976. Axt later attributed ...
