为研究乐安江流域重金属的污染状况,于2008年12月在流域采集了水样和底泥,并在实验室用离心机离心底泥得到间隙水,用原子吸收方法测定底泥中重金属(Cu,Pb,Zn,Cd)的浓度含量和水体中重金属(Cu,Pb)的含量.结果表明,乐安江水体中重金属含量没有超过地表水环境质量标准Ⅲ,而底泥中重金属含量平均值与国家土壤环境质量标准Ⅲ相比,只有Cd未能达到标准.在浓度含量上,低泥中最高,间隙水中次之,水体中最少.
為研究樂安江流域重金屬的汙染狀況,于2008年12月在流域採集瞭水樣和底泥,併在實驗室用離心機離心底泥得到間隙水,用原子吸收方法測定底泥中重金屬(Cu,Pb,Zn,Cd)的濃度含量和水體中重金屬(Cu,Pb)的含量.結果錶明,樂安江水體中重金屬含量沒有超過地錶水環境質量標準Ⅲ,而底泥中重金屬含量平均值與國傢土壤環境質量標準Ⅲ相比,隻有Cd未能達到標準.在濃度含量上,低泥中最高,間隙水中次之,水體中最少.

To learn the conditinon of heavy metals pollution in Le An river, the water and sediment were collect in December 2008, and centrifilgaled the sediment to get interstitial water in the laboratory. Measured the content of heavy metals of sediment (Cu, Pb, Zn, Cd) and water (Cu, Pb) by atomic absorption. The results showed that heavy metal content in water An river do not exceed the surface water environmental quality standards Ⅲ. Compared the average content of heavy metals in sediment to the National Soil Environmental Quality Standard Ⅲ, only Cd could not meet the standard. The sediment had the highest concentrations, followed by the interstitial water, water at least.
