摘　　要：为了研究安徽省部分地区水环境中重元素污染的状况,作者利用同步辐射X射线荧光,对于采自安徽省境内4个地区的日本沼虾(Macrobranchiumnipponensis)的尾扇样品进行重元素分析,测定结果表明:它反映了4个地区的水体中沼虾体内重元素含量的差别,这显示出沼虾体内重元素的含量随着水环境的不同而改变,从而体现了本实验方法对水环境污染的指示意义。在实验中我们证实,与一般检测样本重元素的方法相比,同步辐射X射线荧光分析的方法的灵敏度大大提高,样品处理也更加简便。In order to study the effect of heavy elements pollution in water environment upon the animals, tail fan samples of Macrobranchium nipponensis from four regions of Anhui Province are heavy-elements-analyzed with SR X-ray fluorescence. The accumulated heavy elements in Macrobranchium nipponensis living in four different river or pools are varied with their living environment. The result embodies the directive significance of the research in pollution of water environment. Compared to the general method to measure heavy elements in the sample, it has been proved in our experiment that the sensitivity has been improved in the SR-XRF, and the more convenient treatment of the sample has also been carried on.
