摘要 

本项工作对沈阳市西部100km2范围内的表层和底层土壤进行了环境地球化学研究,运用多种数理统计方法,求得本区15种元素的土壤背景值及其范围,依照单元素评价指数和综合评价指数对土壤的环境质量进行了评价,认为存在着严重的Cd、Pb、Zn、Cu、As、Sb、Hg等重金属元素的污染.污染区沿张士灌渠由上游至下游有不断扩大的趋势.造成污染的主要原因是长期污水灌溉,同时查明底泥是一种新的次生污染源.

Abstract

Environmental geochemical studies were conducted for surficial and bottomsoils in an area of 100km2 in the west of Shenyang City proper. Soil back-ground values of fifteen elements in this district were obtained by means ofquite a few statistic techniques; environmental quality of soil was evaluatedaccording te single element assessment indices and integrated assessmentindices, and it is considered that there exists severe contamination from suchheavy metal elements as Cd, Pb, Zn, Cu, As, Sb and Hg. The contaminated areatends to expand progressively from the upper to lower reaches of the Zhangshiirrigation canal, and such contamination results mainly from long-time sewageirrigation. It is also ascertained that bottom mud is a sort of new secondary contamination source.
