Editing Cobalt(II) chloride (section)

==Health issues==
Cobalt is essential for most higher forms of life, but more than a few milligrams each day is harmful.  Although poisonings have rarely resulted from cobalt compounds, their chronic ingestion has caused serious health problems at doses far less than the lethal dose. In 1966, the addition of cobalt compounds to stabilize [[beer foam]] in Canada led to a peculiar form of toxin-induced [[cardiomyopathy]], which came to be known as ''beer drinker's cardiomyopathy''.<ref>{{cite journal |author= Morin Y |author2= Tětu A |author3= Mercier G|title=Quebec beer-drinkers' cardiomyopathy: Clinical and hemodynamic aspects |journal=Annals of the New York Academy of Sciences |volume=156 |issue= 1 |pages=566–576 |date=1969|pmid=5291148 |doi=10.1111/j.1749-6632.1969.tb16751.x|bibcode = 1969NYASA.156..566M |s2cid= 7422045 }}</ref><ref>{{cite journal|title = Cobalt|author = Barceloux, Donald G.|author2 = Barceloux, Donald|name-list-style = amp |doi = 10.1081/CLT-100102420|pmid = 10382556|journal = Clinical Toxicology|volume = 37|issue = 2|date = 1999| pages = 201–216}}</ref><ref>[https://pubchem.ncbi.nlm.nih.gov/compound/Cobalt_sulfate#section=Human-Toxicity-Excerpts   11.1.5 The unusual type of myocardiopathy recognized in 1965 and 1966 in Quebec (Canada), Minneapolis (Minnesota), Leuven (Belgium), and Omaha (Nebraska) was associated with episodes of acute heart failure (e/g/, 50 deaths among 112 beer drinkers).]</ref>

Furthermore, cobalt(II) chloride is suspected of causing [[cancer]] (i.e., possibly [[carcinogen]]ic, [[IARC Group 2B]]) as per the [[International Agency for Research on Cancer]] (IARC) Monographs.<ref>[http://publications.iarc.fr/_publications/media/download/2705/29aacee6b89ff816188dcd990b61a16ad6486eec.pdf [PDF]</ref>

In 2005–06, cobalt chloride was the eighth-most-prevalent [[allergen]] in [[patch test]]s (8.4%).<ref>Zug KA, Warshaw EM, Fowler JF Jr, Maibach HI, Belsito DL, Pratt MD, Sasseville D, Storrs FJ, Taylor JS, Mathias CG, Deleo VA, Rietschel RL, Marks J.
