This study was designed as the first to assess the trace metal (Cd, Cu, Fe, Mn, Ni and Zn) in coral skeleton in relation to metal availabilities and sampling locations in Sabah. The study also aims to determine the differential abilities of Scleractinian coral species as a bioindicator of environmental conditions. Skeletons of Scleractinian coral (Hydnophora microconos, Favia speciosa and Porites lobata) showed concentrations of Fe, Mn and Ni relatively higher than Cd and Zn in the skeletons. Statistical analyses outputs showed significant relationships between trace metal concentrations in coral species and those in seawater and sediment. The highest bioaccumulation factors among three Scleractinian coral species investigated was for Zn followed by Mn, Ni, Fe, Cd and Cu can provide a sign about pollution levels. However, metal tolerance, coral structure and morphology as well as multispecies monitoring are factors that need to be a focus in future studies.
本研究旨在首次评估沙巴地区珊瑚骨骼中的痕量金属（Cd、Cu、Fe、Mn、Ni 和 Zn）与金属生物有效性和采样地点之间的关系。本研究还旨在确定石珊瑚物种作为环境条件生物指标的差异能力。石珊瑚（Hydnophora microconos、Favia speciosa 和 Porites lobata）的骨骼中 Fe、Mn 和 Ni 的浓度相对高于骨骼中的 Cd 和 Zn。统计分析结果表明，珊瑚物种中的痕量金属浓度与海水中和沉积物中的痕量金属浓度之间存在显著关系。在所研究的三种石珊瑚物种中，Zn 的生物积累因子最高，其次是 Mn、Ni、Fe、Cd 和 Cu，可以提供有关污染水平的迹象。然而，金属耐受性、珊瑚结构和形态以及多物种监测是未来研究需要关注的因素。
