The accumulative partitioning of Pb and Cu in the Rhizophora apiculata was studied randomly in the Setiu mangrove forest, Terengganu. Samples of leaves, barks and roots were collected randomly from the selected studied species. Sediments between the roots of the sampled mangrove plants were also collected. The results from analysis for Rhizophora apiculata shows that the concentration of Pb and Cu were accumulated higher in root tissue compared to bark and leaf tissue but lower than surrounding sediment level. The average concentration of Cu for Rhizophora apiculata in leaf, bark, root and sediment was 2.73, 3.94, 5.21 and 9.42 mg I(-1), respectively. Meanwhile, the average concentration of Pb in leaf, bark, root and sediment was 1.43, 1.38, 2.05 and 11.66 mg l(-1), respectively. Results of concentration factors (CF) show that the overall the concentration of Pb and Cu were accumulated much higher in roots system of Rhizophora apiculata.
在登嘉楼州的仕林红树林中，对尖瓣海莲中铅和铜的累积分配情况进行了随机研究。从选定的研究物种中随机采集叶片、树皮和根系样本。还采集了采样红树林植物根系之间的沉积物。尖瓣海莲的分析结果表明，与树皮和叶片组织相比，根组织中铅和铜的浓度积累更高，但低于周围沉积物水平。尖瓣海莲叶片、树皮、根和沉积物中铜的平均浓度分别为2.73、3.94、5.21和9.42毫克/升。同时，叶片、树皮、根和沉积物中铅的平均浓度分别为1.43、1.38、2.05和11.66毫克/升。浓度因子（CF）的结果表明，总体而言，尖瓣海莲根系中铅和铜的浓度积累要高得多。
