Abstract
A study has been conducted in the Kuala Sepetang mangrove forest area. The study was focused on four heavy metals that were zinc Zn lead Pb nickel Ni and copper Cu. A total of 65 samples were collected in the surface layer 0-10 cm of sediment around e study area. The sediment samples collected were from five rivers which is Sg. Reba Sg. Sepetang Sg. Selinsing Sg. Sangga Besar and Sg. Sangga Kecil. These rivers are connected at the Kuala Sepetang river mouth. Also a total of 22 samples of sediment ere also collected from the sandy beach of Pasir Panjang area. Pasir Panjang is located south to Kuala Sepetang area and is still in pristine condition. Concentration of heavy metals in these sandy beach samples were used as background values. In Kuala Sepetang It and clay were dominant 85 while in Pasir Panjang sand was dominant 90. both places quartz mineral were found in abundance. The total heavy metals in the sediments were extracted using Aqua-Regia method. The range of heavy metals concentrations in Kuala Sepetang for Ni 5.2-36 mg/kg Zn 52.4-312.80 mg/kg Pb 1.8-159.60 mg/kg and Cu 7.6-31.20 mg/kg are comparable with other Malaysian dies. These values are also comparable with study accepted as clean mangrove area Preda and Cox 2002 and also found lower than the trigger value suggested by NZECC/ARMCENZ 2000 Jones et al. 2005. The range of heavy metal concentrations in the Pasir Panjang sand is much lower for Ni 2.40-22.80 mg/kg Zn 2-199.60 mg/kg Pb 0.80-4.40 mg/kg and Cu 5.20-29.60 mg/kg. The heavy metal concentrations value of this study can be used as baseline values in future study of the mangrove forest around Malaysia.
