Heavy metal pollution and their spatial distribution in urban soils of Fuzhou
By analysis of the spatial distribution of heavy metals in surface soil in Fuzhou, we found the soil have been contaminated in different levels, especially for contents of Pb, Zn, Cr in all the sample points far exceeded Background value in soil of Fujian Province. Some pro-sulfur and pro-iron elements have similar properties, so their variation of contents show good correlation. The features of the spatial distribution of heavy metal element Pb, Zn, Sr, Cu, Cr contents are very regular, their contents are seriously affected by human activities. Changes of Zr, Rb, Fe, Ni contents have no notable regularities, the pattern of these types of element may be more important controled by the contents of soil materials, and the impact of man-made pollution is not very significant. Compared with Background value of soil in Fujian Province, we find Zr, Rb, Fe, Ni pollutions are lighter than pollutions of Pb, Zn and other elements.
