| Abstract | The benthic biological resources in Batu Belubang Waters exhibit significant diversity,and as one of Bangka Island's unconventional tin mining as well as post-tin-mining areas,understanding its impact on aquatic life is very important. Therefore, this study aimed todetermine the potential risk of heavy metals in post-tin-mining sediments using an EcologicalRisk Index (ERI) analysis approach. Purposive sampling was conducted in the post-tin miningareas of Batu Belubang waters. Heavy metal measurement was carried out using InductivelyCoupled Plasma - Optical Emission Spectroscopy (ICP-OES). The results showed that thecontamination factor (CF) of heavy metals for Cd, Pb, Co, and Ni in sediments were within thecriteria of low pollution level (CF < 1), and the value of Pollution Load Index (PLI) was below1, showing an unpolluted classification. Furthermore, ERI analysis of Cd, Pb, Co, and Ni, insediments also showed low ecological risk criteria (ERI < 150). The texture of the substrate inthe post-tin mining area is dominated by sand, with the base layer exhibiting relative weakness,leading to a slight resuspension, and distribution of heavy metals in the sediment. There is lowmetal accumulation in tissues, which does not interfere with the metabolism and growth ofbenthos. The results showed a low ecological risk, suggesting the resilience of the ecosystemto post unconventional tin mining. |
