The expression Hunter-Russell syndrome derives from a examine of mercury poisoning amongst personnel in a very seed-packaging manufacturing facility in Norwich, England in the late 1930s who breathed methylmercury which was remaining used to be a seed disinfectant and pesticide.[ninety one]
Acrodynia is tricky to diagnose; "it truly is most frequently postulated which the etiology of this syndrome is definitely an where to buy red mercury idiosyncratic hypersensitivity response to mercury due to the deficiency of correlation with mercury concentrations, many of the signs resemble identified mercury poisoning."[109]
