| Abstract: | In this paper, proceed from the environment characteristic of the Nenjiang river, background values of some elements, such as Cu, Pb, Zn, Cd, Cr, Ni, Hg As were determined with the methods of geochemistry and mathematical statistics, based on extensive sampling. The influence of size of the deposit sediment and the chemical composition of rock on the background values have been discussed, Moreover, the distribution law of elements in the deposit sediment has been analyzed. |
