| Abstract | The sediment of the Sarcheshmeh copper mine in Iran contains high concentrations of trace metals. In this risk assessment study, criteria such as contamination factor, pollution load index, and geoaccumulation index were used to assess levels of Co, Cu, Mo, Zn, Cr, Mn, Ni, Pb, Ti, and Fe in the mine sediment released to the tailings dam. Expert opinions on the relative importance of each of the indicators were used to assign a final weighting of the criteria using the fuzzy Delphi analytic hierarchy process, and the metals in the sediments of the study area were ranked and clustered using the TOPSIS method. Based on the results, the metals were clustered into 10 categories with copper, iron, and zinc having the highest pollution and critical risk.Das Sediment des Sarchesmeh-Kupferbergwerkes im Iran zeigt hohe Konzentrationen an Spurenmetallen. Bei der vorliegenden Studie zur Gefährdungsabschätzung wurden die Kriterien wie der Kontaminationsfaktor, Umweltbelastungsindex und Geoakkumulationsindex verwendet, um den Grad der Freisetzung von Co, Cu, Mo, Zn, Cr, Mn, Ni, Pb, Ti und Fe aus den Bergbausedimenten in die Staudamm zu bestimmen. Zur relativen Wichtung der einzelnen Indikatoren wurden Expertenmeinungen eingeholt und letztendlich in einen fuzzy Delphi analytic hierarchy process verarbeitet. Die Metalle in den Sedimenten wurden anschließend mit der TOPSIS-Methode gewichtet und klassiert. Auf Basis der Ergebnisse erfolgte die Klassierung der oben genannten Metalle in 10 verschiedene Kategorien, wobei Kupfer, Eisen und Zink die größte Verschmutzung verursachen und bereits ein kritisches Niveau erreicht haben.El sediment de la mina de cobre Sarcheshmeh en Irán contiene altas concentraciones de metales traza. En este estudio de relevamiento ambiental, se usaron criterios tales como factor de contaminación, índice de polución e índice de geoacumulación para relevar los niveles de Co, Cu, Mo, Zn, Cr, Mn, Ni, Pb, Ti y Fe en los sedimentos de la mina provenientes del dique de cola. Se utilizaron opiniones expertas sobre la importancia relativa de cada indicador para asignar un peso final del criterio utilizando el proceso analítico hierático difuso Delphi (FDAHP) y los metales de los sedimentos en el área de estudio fueron clasificados y agrupados usando el método TOPSIS. En base a estos resultados, los metales fueron agrupados en 10 categorías con cobre, hierro y cinc presentando la máxima polución y riesgo crítico.伊朗Sarcheshmeh铜矿矿床沉积中含有较多微量金属元素。在污染风险评估中,本文以污染因子、污染负荷指数和地质积累指数等作为评价铜矿释放至尾矿坝中的Co、 Cu、 Mo、 Zn、 Cr、 Mn、 Ni、 Pb、 Ti和Fe等污染评价指标。通过模糊德尔菲层次分析法(FDAHP)实现每一评价指标的重要性专家意见权重分配,利用TOPSIS方法实现研究区内金属离子排序、聚类。基于以上分析结果,研究区尾矿坝内金属离子被分为10类,铜、铁和锌具有最大污染风险。 |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
