摘要
本文以澴河流域孝南段为研究区域,共采集分析了土壤样品34个,并在土壤质量评价的基础上,利用主成分分析法(PCA)对污染物的来源进行了分析。结果表明,该区域内的重金属Cu、Cd、Pb主要来源于道路交通;Cr、Ni、Cu、Pb一般与成土母质有关,其中超标的主要与周围电子元件厂的生产有关;As、Hg、N、P等元素主要与大量使用化肥、农药及排放生活污水和固体废弃物的堆积有关。以上结果可为研究区城的土壤污染防控提供参考依据。
In this paper,34 soil samples were collected and analyzed in Huanhe River Basin Xiaonan section,and based on soil quality evaluation,principal component analysis(PCA)was used to analyze the sources of pollutants.The results showed that the heavy metals Cu,Cd and Pb in the area mainly originate from road traffic;Cr,Ni,Cu and Pb are generally related to the parent material of soil formation,among them exceed the standard mainly with the production of electronic components around the factory;As,Hg,N,P and other elements are mainly related to the massive use of chemical fertilizers and pesticides and the discharge of domestic sewage and solid waste accumulation.The above results may provide reference for soil pollution control in the study area.
