在土耳其北方工业城市伊兹米特，利用磁化率（MS）测量方法对表层土壤重金属污染进行了研究。我们试图调查选定的重金属浓度和MS之间的相关性从41个采样点周围伊兹米特海湾。这些调查让我们量化和标准化的MS方法，这可能会产生长期监测人为污染的后果，特别是在城市地区。根据表层土壤测量结果编制了MS冲浪等值线图，其距离密度随机变化。在工业区、公园、路边和居民区采集的土壤样品也用原子吸收光谱仪进行了分析。重金属Cu、Ni、Cr和Pb与MS具有较强的相关性，而Zn和Co与MS具有较弱的相关性。此外，Tomlinson污染负荷指数（PLI）与MS的相关性不显著。最大值大多出现在2-5厘米的深度，深度剖面上的MS值在10 x10（-8）m（3）kg（-1）和203 x10（-8）m（3）kg（-1）之间变化。该研究表明，MS是一种廉价，快速和非破坏性的方法，用于检测和绘制污染土壤。(C)2009爱思唯尔有限公司版权所有。
The study on topsoil contamination due to heavy metals was carried out by using the Magnetic susceptibility (MS) measurements in Izmit industrial city, northern Turkey. We attempted to investigate correlations between the concentration of selected heavy metals and the MS from 41 sample sites around Izmit Gulf. These investigations let us quantify and standardize the MS method, which may have consequences for long term monitoring of anthropogenic pollution, especially in urban areas. The MS surfer contour map based on the topsoil measurements was compiled with a randomly ranged distance density. The soil samples collected throughout the industrial areas, the parks, road sides and residential areas were also analyzed by Atomic Absorption Spectrometer. Heavy metals Cu, Ni, Cr and Pb show strong correlations with MS, while Zn and Co show a weak correlation with MS. Moreover, the Tomlinson pollution load index (PLI) shows insignificant correlation with the MS.The MS was examined vertically (0-30 cm) with respect to anthropogenic and/or lithogenic influences at the fourteen sample sites. The maximum values were mostly observed in depths of 2-5 cm and the MS values on the depth profiles vary between 10x10(-8) m(3) kg(-1) and 203x10(-8) m(3) kg(-1). The study revealed that MS is an inexpensive, fast and non-destructive method for the detection and mapping of contaminated soils. (C) 2009 Elsevier B.V. All rights reserved.
