摘要
通过 1987— 1995年对对四平市条子河底泥和水质的同步监测 ,指出四平市条子河底泥中重金属含量较高 ,污染河段底泥中重金属的含量比背景含量要高出 1～ 3.97倍 ,年际变化出现波状起伏的特征。底泥的含量受到河流水质的酸 (碱 )特性和氧化特征的影响 ,同时受区域环境背景的影响和工业废物排放的影响。
Based on the monitor of sediment and water in Tiaozi river in Siping city from 1987 to 1995, some characteristics of heavy metals in the sediment are pointed out. The content of heavy metals in the sediment was high and it in the polluted sediment was 1~3.97 times of that of the background, the annual variation was undulant. The content of heavy metals in the sediment is affected by the acidification or alkali and oxidation of water, the regional background and the drainage of industry waste water. At last, some ecological and chemical countermeasures to control the heavy metal in sediment are given out.
