某钢厂周边土壤重金属与磁化率分布规律及情况监测

Distribution and Condition Monitoring of Heavy Metal and Magnetic Susceptibility in the Surrounding Soil of a Steel Plant

对某钢厂周边土壤进行了重金属和磁化率的测定,分析了其分布的规律以及相关性。结果表明,钢铁厂内部表层土壤污染比较严重,主要污染要素是Pd以及Cr,重金属含量高的区域,其磁化率值也比较高。剖面重金属的Pd积累明显,属于中度污染。相关性的分析表明了研究区土壤磁化率值和重金属元素pd、Zn的含量呈正相关的关系。

The determination of heavy metal and magnetic su sceptibility in the surrounding soil of a steel plant was carried out, and the regularity and correlation of its distribution were analyzed. The results showed that the surface soil pollution of iron and steel plants is relatively serious. The main pollution factors are Pd and Cr, where contains high content of heavy metals and magnetic susceptibility. The Pd accumulation of heavy metals in the section is obvious,which belongs to moderate pollution. The correlation analysis shows that the there is a positive correlation between the soil magnetic susceptibility and the content of heavy metals PD and Zn in the study area.
