| 摘 要： | 利用HaKanson生态风险指数法，研究了大沽排污河底泥中污染物重金属和砷对水域的污染程度，及其对水域总体造成的潜在风险影响。同时利用多环境要素评价方法，对大沽排污河水质、污灌区土壤作物及生态效应进行了多元综合评价，2种方法结论相吻合。大沽排污河生态风险处于重度污染水平。重金属和砷污染物对生态风险影响排序为 :Hg>Cd >Cu >As>Pb >Cr>Zn。

| Abstract: | The pollution degree of heavy metals and arsenic in the bottom sludge of Dagu pollution-discharging river on the watershed is researched using Hakanson ecological risk index.A multivariate overall assessment is carried out on water quality,sewage irrigation region crops and ecological effect of Dagu pollution-discharging river by multienvironmental-factor evaluation.The conclusions of the two methods is the same,i.e.there exists a heavy pollution in this river.The order of the effect of heavy metals and arsenic is:Hg>Cd>Cu>As>Pb>Cr>Zn. |
