通过对吉林松花湖及其上游入湖河流水质、底泥、动植物样品中重金属污染的调查和评价,发现20世纪80年代初开始基本得到控制的汞污染现象又呈加重趋势.底泥中汞富集系数较20世纪80年代上升1(5倍;受污染水体中的两栖动物林蛙体内甲基汞呈富集状态,较未污染河流中林蛙体内高2(29倍.汞污染的来源是上游个体手工式小采矿点随意倾倒尾矿渣,随降雨径流进入河流所致.
Through the investigation and evaluation of heavy metal pollution in Songhuahu Lake and upstream rivers into Jilin Lake, it was found that mercury pollution basically controlled in the beginning of 1980s tended to increase again. The enrichment coefficient increased by 1 (5-fold compared with that in the 1980s; the abundance of methylmercury in amphibian frogs in contaminated water was 29% more than in uninfected river frogs It is due to the runoff of runoff tailings into the river at the small hands-on mining sites of the upper reaches.
