摘要: 通过对浑河流域内底质采样,系统分析As、cd、Cr、Cu、Hg、Ni、Pb和zn等8种重金属元素,了解其含量和空间分布等特征.研究证实,冶炼和化工生产等对浑河底质的地球化学特征带来极大影响,造成细河等区域内的底质中Cd等重金属元素含量升高.对浑河底的系统分析工作,为深入研究流域环境质量和农业规划等提供借鉴方法和基础数据.Abstract: In order to get the clear understanding of the content and distribution features of eight heavy metal elements, including As, Cd, Cr, Cu, Hg, Ni, Pb and Zn, the sediment samples from Hunhe river, which flows through the Shenyang and Fushun cities, were sampled and analyzed. The results from this study confirm that the industrial activities along the river strongly affect the geochemistry features of sediments in Hunhe river drainage area and cause heavy metal contamination, especially cadmium contamination. The study also provides the methods for further environment quality research and basic data for agriculture planning in this river drainage area.
