| 摘 要： | 为了解饶河入鄱阳湖湖口重金属污染状况,在鄱阳湖饶河入湖段设置了3个采样点,用原子吸收分光光度计对沉积物进行了重金属Cu、Pb、Zn的测定,分析了这3种元素在各采样点的形态分布特征.结果表明:饶河人鄱阳湖口处沉积物中Cu、Pb、Zn的污染较为严重,呈现出复合污染的趋势.该区域沉积物中3种元素的分布受水流的影响较大,其形态... |

| Abstract: | In order to know heavy metal pollution situation of Raohe river into Poyang Lake,concentrations of Cu,Pb and Zn were determined by atomic absorption spectrometer in sediment samples which collected in 3 sampling sites.Fractions of the 3 elements were analyzed.The results showed that sediment pollution of Cu,Pb and Zn at Raohe estuary were relatively serious.Geochemical distribution of the 3 elements was largely influenced by water flow.Chemical speciation of the 3 elements mostly consisted of organic matter and residual bound fraction and bioavailability speciation poorly contained such as exchangeable fraction and acid extractable fraction.Ratios of exchangeable fraction,acid extractable fraction and iron-manganese oxide bound fraction of Pb were higher than that of Cu and Zn.Pollution control was armed at Pb because the element had a great danger to organism. |
