【摘要】 2004年,在对白洋淀湖区21个监测点底泥的8个指标检测调查基础上,参照国内有关标准,建立了底泥污染评价标准,评价结果表明,白洋淀底泥重金属元素Cd、Pb的污染较普遍,且多为2种以上的复合污染,污染危害顺序为Cd>Pb>Zn>Cu。重金属综合污染指数为3.583,达5级,为重度污染。府河入淀处的安新大桥、南刘庄、同口、梁庄、王家寨底泥污染最为严重。底泥总体上肥力水平很高,部分底泥可作为有机肥施于土壤。更多还原

【Abstract】 Investigation in 2004 about the sediment in Baiyangdian Lake was made. There were 21 monitoring sites,monitoring items were Cu、Zn、Cd、Pb、TN、TP、TOC and pH.By consulting domestic relevant standard,sediment pollute evaluation criterion was set up.The results showed that the sediment pollution from the heavy metal(Cd and Pb) was quite obvious,and most of them were seen.The sediment samples were highly polluted by Cd,pollution endangering order as Cd>Pb>Zn>Cu.The synthetic index of sediment pollution was 3.583,which was five grade strong pollution.The bridge of Anxin,SouthLiu village,Tongkou,Liangzhuang,Wangjiazhai were sites which were the most serious in pollution.更多还原
