Review: Mekanisme Akumulasi Logam Berat di Ekosistem Pascatambang Timah

Abstract

Tin exploration and exploitation activiy have caused damages and changes of ecosystem. The macroecosystem can caused to microecosystem changes directly. One of ecological effect was caused by tin mining, that heavy metal existence. The heavy metal accumulation can influenced chemical and physical structure of an ecosystem such as pH value and high level of heavy metal residue. The extrem of physical and chemical status impacted to ability of macro and microorganisms to survive in the environment. This articles review aims to describe the potential of heavy metals contamination like As, Cr, Cu, Pb, Zn, Fe, and Zn that found in tin mining locations, its toxicity, the machanisms of heavy metals accumulation in an organism, and treatments for decontaminant by bioremediation. This review’ expectancy can be an important information in a management of ex-tin mining for environment utilization and development in long lasting and sustainable.
