Abstract:
The aim of the study was an assessment of the pollution level and identification of the antimony sources in soils in areas subjected to industrial anthropopressure from: transport, metallurgy and electrical waste recycling. The combination of soil magnetometry, chemical analyzes using atomic spectrometry (ICP-OES and ICP-MS), Sb fractionation analysis, statistical analysis (Pearson\'s correlation matrix, factor analysis) as well as Geoaccumulation Index, Pollution Load Index, and Sb/As factor allowed not only the assessment of soil contamination degree, but also comprehensive identification of different Sb sources. The results indicate that the soil in the vicinity of the studied objects was characterized by high values of magnetic susceptibility and thus, high contents of potentially toxic elements. The most polluted area was in the vicinity of electrical waste processing plants. Research has shown that the impact of road traffic and wearing off brake blocks, i.e. traffic anthropopression in general, has little effect on the surrounding soil in terms of antimony content. Large amounts of Pb, Zn, As and Cd were found in the soil collected in the vicinity of the heap after the processing of zinc-lead ores, the average antimony (11.31 mg kg-1) content was lower in the vicinity of the heap than in the area around the electrical and electronic waste processing plant, but still very high. Antimony in the studied soils was demobilized and associated mainly with the residual fraction.
摘要:
研究的目的是评估受工业人为压力影响的地区土壤中的锑源的污染水平和识别:运输,冶金和电气废物回收利用。土壤磁力测量的组合,使用原子光谱(ICP-OES和ICP-MS)进行化学分析,Sb分馏分析,统计分析(皮尔逊相关矩阵,因子分析)以及地质累积指数,污染负荷指数,和Sb/As因子不仅允许评估土壤污染程度,还可以对不同的Sb源进行综合鉴定。结果表明,研究对象附近的土壤具有较高的磁化率,因此,高含量的潜在有毒元素。污染最严重的地区是电气废物处理厂附近。研究表明,道路交通和制动块磨损的影响,即一般的交通人为压迫,锑含量对周围土壤影响不大。大量的Pb,Zn,在锌铅矿石处理后,在堆附近收集的土壤中发现了As和Cd,堆附近的平均锑(11.31mgkg-1)含量低于电气和电子废物处理厂周围地区,但仍然很高。研究土壤中的锑已复员,主要与残留部分有关。
