Abstract

The Munzur and Pulumur streams are essential water supplies of the Tunceli Province (Turkey). Chromite bearing ultramafic rocks and Zn-Cu mineral- ization products are possible causes of the toxic elements enrichment in the streams. Sediment and soil samples were collected along these streams to deter- mine the level of toxic element enrichment. Multi-element normalized patterns of the samples with respect to the upper crust display enrichments in Cr, Ni, Co, Cs, W, Pb, As, Sb, Au, Hg and Cr, Ni, Co, W, for the Munzur and Pulumur streams, respectively. Also, the calculated Igeo index values show the pres- ence of contaminations of Cr, Ni, As, Hg, Cd and Cr, Ni, As in the Munzur and Pulumur streams, respectively. Elemental grouping in the samples indicates two different effects related to the ultramafic host rocks and mineralization products in the study area. Additionally, mineralogical XRD analyses exhibit the presence of chrysotile, plagioclase, quartz and calcite. The fibrous chrysotile and heavy metal contaminations must be considered as a threat for public health.
Munzur和Pulumur溪流中重金属和温石棉的环境污染(土耳其通切利)
Munzur河和Pulumur河是通切利省(土耳其)的重要水源。含铬铁矿的超镁铁性岩石和锌铜成矿产物可能是河流中有毒元素富集的原因。沿着这些河流收集了沉积物和土壤样本,以测定有毒元素的富集水平。样品相对于上地壳的多元素归一化模式显示,Munzur和Pulumur溪流分别富集Cr、Ni、Co、Cs、W、Pb、As、Sb、Au、Hg和Cr、Ni、Co、W。此外,计算出的Igeo指数分别显示Munzur河和Pulumur河中存在Cr、Ni、As、Hg、Cd和Cr、Ni、As污染。样品中的元素分组显示出与研究区超镁质寄主岩和成矿产物有关的两种不同作用。此外,矿物学XRD分析显示存在温石棉、斜长石、石英和方解石。纤维温石棉和重金属污染必须被视为对公众健康的威胁。

期刊介绍: Since 1976, Ofioliti provides an international forum for original contributions and reviews in the field of the geodynamics, petrology, geochemistry, biostratigraphy, stratigraphy, tectonics and paleogeography applied to ophiolitic terrains and modern oceanic lithosphere, including their sedimentary cover. Studies of topics such as geodynamics of the mantle, the evolution of orogens including ophiolites and paleoceanography are also welcome
