In the present paper the methyl mercury pollution in no. 2 Songhua river is reported. After ten years of continuous investigation, it was found that the health of fishermen who had eaten mercury polluted fish as a dietary for a long time was affected. There was an accumulation of methyl mercury in the fishermen's body and symptoms and pathologic changes related to toxication by methyl mercury. The average value of mercury content in fish (0.44-0.89 ppm) was shown to be above the maximum allowable concentration by one to three times. The intake of methyl mercury by the fishermen was in the range of 0.17-0.34 mg/per day and 90% of the mercury in the fishermen's body was from the polluted fish. The average mercury content in hair was 13-58 times higher than that of normal. The mercury concentration in urine after therapy was higher than that before by 10.6 to 33.3 times. There was a close correlation between mercury content in hair and in blood and the ratio was shown to be 250:1. The hazard of methyl mercury to fishermen was discussed.
本文报道了松花江二号水域的甲基汞污染情况。经过十年的持续调查，发现长期以受汞污染的鱼类为食的渔民健康受到影响。渔民体内有甲基汞蓄积，并出现了与甲基汞中毒相关的症状和病理变化。鱼类汞含量平均值（0.44 - 0.89 ppm）高于最大允许浓度一至三倍。渔民甲基汞摄入量在0.17 - 0.34毫克/天范围内，其体内90%的汞来自受污染的鱼类。头发中汞平均含量比正常情况高13 - 58倍。治疗后尿汞浓度比治疗前高10.6至33.3倍。头发和血液中的汞含量之间存在密切相关性，其比例为250:1。文中还讨论了甲基汞对渔民的危害。
