Albuminuria at Lake Murray due to high methylmercury intake.

A clinical examination of 24 subjects having a high intake of methylmercury through fish consumption showed no individual symptoms or signs that could be due to mercury poisoning. However, nearly 40% of the subjects (9) had significant amounts of albumin in the urine. The mean concentrations of mercury in hair and urine were 12.0 mg/kg (81% methylmercury) and 23 mg/kg (35% methylmercury) respectively. No correlation, however, was found between the incidence of albuminuria and mercury levels in hair or urine.
