Fishes in the middle reaches of the Second Songhua River in Jilin Province were heavily contaminated by methyl mercury, the average content of 61 fish samples being 0.42 mg/kg. The upper and lower reaches were less contaminated and the averages were 0.12 mg/kg (53 samples) and 0.08 mg/kg (20 samples), respectively. The average methyl mercury content of fishes (20 samples) collected from a nearby "nonpolluted" water reservoir was 0.03 mg/kg. In a total of 134 fish samples collected from the Second Songhua River, 41% of the samples had a methyl mercury content exceeding the National Tolerance Limit of 0.2 mg/kg.
