松花江哈尔滨段鱼体甲基汞及分析方法的研究

Research on Cymene Hydrargyrum in Fish Bodies in Harbin part of Songhua River and its Analyzed Method

作者通过对松花江哈尔滨段的几种天然鱼类 (鲤、鲫、鲶、鲢、草、鱼 )鱼体的甲基汞含量的调查检测 ,进一步搞清工业污水中重金属污染物———汞的污染现状。检测结果显示该江段的鱼体甲基汞含量均值为0.085mg/kg ,已超过国家淡水鱼类食品卫生标准0.025mg/kg 的2.4倍。5种鱼类中以鲶鱼所含甲基汞最高 (0.115mg/kg) ,与其生活习性及食品店性有关 ,表明甲基汞的蓄积与食物链密切相关。从鱼体的组织器官看 ,脑组织中的甲基汞含量显著高于背部肌肉组织和头部组织 ,表明甲基汞属脂溶性 ,易于在脑组织中蓄积。调查结果表明该江段现已存在较严重的汞污染 ,说明汞污染已从上游迁移到哈尔滨。鉴此情况希望能引起政府有关部门的关注。同时本文还对鱼体中甲基汞检测的分析方法进行了研究。

Cymene Hydrargyrum in several savage fish bodies in Harbin part of Songhua river and its analyzed method were investigated in this paper.The results shows that cymene Hydrargyrum pollution in fish is serious,and it must be set store by the government Otherwise,it will harm the people's health.
