Brunei Bay, Borneo is a unique water ecosystem which has been conserved a wide range of wildlife. Hitherto, the rapidly increase of human activities has been denoted surround and within the bay ecosystem. Four sediment cores has been collected within Brunei Bay with the purpose of assessing metal’s pollution level and geochemical characteristics of the cores. Metals total concentration, sediment physico-chemical characteristic, and sediment sequential extraction analysis were determined in each layer of the sediment cores. Generally, all metals showed different pattern of enrichment or depletion in each core. Sediment core of station LB recorded the highest average of metals compared to other sediment cores. Brunei Bay sediment cores are dominant by silt with low total organic carbon (TOC) content. However, both parameters are not affecting the concentration of metals in the bay sediment. Largely, all metals in all sediment cores are classiffied as uncontaminated-to-moderately contaminated except for lead (Pb). During the period of 1980’s, Pb was moderately-to-strongly contaminated at station LB. It is most probably caused by the high usage of local boat and Labuan Port activities. The risk assessment code analysis has exhibited that only copper (Cu) has low risk on the benthic health in Brunei Bay sediment especially for station B5 and B7. In overall, Brunei Bay sediment shows no significant pollution caused by the metals; however, metal enrichment behavior in the sediment will increased the pollution risk on the bay ecosystem in the future.

婆罗洲文莱湾是一个独特的水生态系统，已保存了各种各样的野生动植物。迄今为止，人类活动的迅速增加被表示为海湾生态系统的周围和内部。文莱湾已收集了四个沉积物岩心，目的是评估金属的污染水平和岩心的地球化学特征。确定了沉积物芯的每一层中的金属总浓度，沉积物理化特性​​和沉积物顺序萃取分析。通常，所有金属在每个核中均表现出不同的富集或耗尽模式。与其他沉积岩心相比，LB站的沉积岩心记录了最高的金属平均含量。文莱湾的沉积物芯主要由低总有机碳（TOC）含量的淤泥组成。然而，这两个参数都不会影响海湾沉积物中金属的浓度。基本上，除铅（Pb）外，所有沉积物岩心中的所有金属都归类为未污染至中度污染。在1980年代，铅在LB站受到了中度至重度污染。这很可能是由于当地船只和纳闽港口活动的频繁使用造成的。风险评估代码分析表明，仅铜（Cu）对文莱湾沉积物底栖健康的风险较低，尤其是B5和B7站。总体而言，文莱湾沉积物没有显示出由金属引起的重大污染；然而，沉积物中金属的富集行为将在未来增加海湾生态系统的污染风险。除铅（Pb）以外，所有沉积物芯中的所有金属均分类为未污染至中度污染。在1980年代，铅在LB站受到了中度至重度污染。这很可能是由于当地船只和纳闽港口活动的频繁使用造成的。风险评估代码分析表明，仅铜（Cu）对文莱湾沉积物底栖健康的风险较低，尤其是B5和B7站。总体而言，文莱湾沉积物没有显示出由金属引起的重大污染；然而，沉积物中金属的富集行为将在未来增加海湾生态系统的污染风险。除铅（Pb）以外，所有沉积物芯中的所有金属均分类为未污染至中度污染。在1980年代，铅在LB站受到了中度至重度污染。这很可能是由于当地船只和纳闽港口活动的频繁使用造成的。风险评估代码分析表明，仅铜（Cu）对文莱湾沉积物底栖健康的风险较低，尤其是B5和B7站。总体而言，文莱湾沉积物没有显示出由金属引起的重大污染；然而，沉积物中金属的富集行为将在未来增加海湾生态系统的污染风险。这很可能是由于当地船只和纳闽港口活动的频繁使用造成的。风险评估代码分析表明，仅铜（Cu）对文莱湾沉积物底栖健康的风险较低，尤其是B5和B7站。总体而言，文莱湾沉积物没有显示出由金属引起的重大污染；然而，沉积物中金属的富集行为将在未来增加海湾生态系统的污染风险。这很可能是由于当地船只和纳闽港口活动的频繁使用造成的。风险评估代码分析表明，仅铜（Cu）对文莱湾沉积物底栖健康的风险较低，尤其是B5和B7站。总体而言，文莱湾沉积物没有显示出由金属引起的重大污染；然而，沉积物中金属的富集行为将在未来增加海湾生态系统的污染风险。
