چکیده

Influence of abandoned tin mine on concentrations, accumulation, mobility and distribution of(Fe, Cu, Ni, and Zn) in surface sediments of Sg. Lembing catchments were investigated in this work.Sediment samples were collected within an abandoned mine of Sg. Lembing Kuantan and also at vicinity area.The sequential extraction method was used to extract anthropogenic metals in sediments and inductivelycoupled plasma mass spectrometry (ICP-MS) was used to determine the metal concentrations. Results indicateall metal in easily or freely leachable and exchangeable (ELFE), Acid reduction (AR) and organic oxidation (OO)fractions were higher than ambient concentrations which indicate heavily metals load from ex-mining intosurrounding aquatic environments. The sequential extraction results showed Cu and Zn were the highest inEFLE fraction, which means these metals are more capable of leaching and cause adverse effects to aquaticorganisms than Fe and Ni. On the other hand, Fe, Cu, Zn and Ni were detected high in OO fraction. Analysisof variance (one-way ANOVA) shows that metal concentrations in each fraction were significant varies betweenstations. Sediment contamination assessment result shows that sediments samples that receive direct acid minedrainage (AMD) water have the highest metals concentrations due to leaching and erosion process.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
