This study aimed to evaluate the spatial and temporal distribution of heavy metals (Cd, Cr, Cu, Co, Fe, Pb, Ni, V, and Zn) in the sediments of Bayan Lepas Free Industrial Zone of Penang, Malaysia. Ten sampling stations were selected and sediment samples were collected during low tide (2012-2013). Metals were analyzed and the spatial distribution of metals were evaluated based on GIS mapping. According to interim sediment quality guidelines (ISQG), metal contents ranged from below low level to above high level at different stations. Based on the geoaccumulation index (I) of sediment, sampling stations were categorized from unpolluted to strongly polluted. The enrichment factor (EF) of metals in the sediment varied between no enrichment to extremely high enrichment. The potential ecological risk index (RI) indicated Bayan Lepas FIZ was at low risk.
本研究旨在评估马来西亚槟城巴眼拉美拉自由工业区沉积物中重金属（Cd、Cr、Cu、Co、Fe、Pb、Ni、V 和 Zn）的时空分布。选择了十个采样站，并在低潮时（2012-2013 年）采集了沉积物样品。对金属进行了分析，并根据 GIS 制图评估了金属的空间分布。根据临时沉积物质量指南（ISQG），不同站位的金属含量从低水平到高水平不等。根据沉积物的地积累指数（I），采样站从无污染到强污染进行了分类。沉积物中金属的富集因子（EF）在无富集到极高富集之间变化。潜在生态风险指数（RI）表明巴眼拉美拉自由工业区处于低风险状态。
