综合化学、毒理学和生态学数据，对乐安河重金属污染的影响进行了评价。结果表明，由于德兴铜矿和沿着济水河矿山的排放，已对济水河水体和沉积物造成污染。德兴铜矿区与吉水河交汇处之间的生态恶化可能是由于酸性排水而不是沉积物中极高的金属含量（非生物可利用），吉水河与下游34 km之间的白色可能是多金属污染。沉积物污染与中度生物和生态恶化盛行在下游的湖泊三角洲地区。(C)1998爱思唯尔科技有限公司版权所有。
By integrating the chemical, toxicological and ecological data, the impact of heavy metal pollution on the Le An River was assessed. The results showed that the water and sediment pollution has affected the aquatic ecosystem due to discharges from Dexing copper mines and mines along the Jishui River. The ecological deterioration between the Dexing copper mine and the converges with the Jishui River could be attributed to acid drainage instead of extremely high content of metals in the sediment (non-bioavailable), white that between the Jishui River and downstream 34 km could be attributed to multi-metal contamination. Sediment pollution associated with the moderate biological and ecological deterioration prevails in downstream of the river as far as the delta area of the lake. (C) 1998 Elsevier Science Ltd.
