摘要
通过近4 a对伊通河长春段6个地表水监测断面中重金属镉的研究,结果表明,地表水中镉的含量随流程的增加而增加,年平均含量也在递增。此外,研究区域内,镉以Cd2+为主,且镉有接近超标并逐年升高的趋势。
The surface water of Yitong River was analyzed at six monitoring sections, the conclusion showed that the yearly average content of Cd was increasing by the transport distance and its yearly average content was increasing. In addition, in the studying region, the main speciation of Cd was Cd^2＋, what＇s more, the potential danger of Cd was very serious.
