<![CDATA[Mangroves have the ability to absorb and store heavy metals such as lead (Pb) and copper (Cu) from the environment. Heavy metals that enter the environment at certain concentrations can be neutralized by hyperaccumulator plants, one of which is mangroves. The objective of this study is to determine the comparison of heavy metal accumulation (lead and copper) in the roote, leaves and sediments of Sonneratia alba mangroves at Tanjung Bunga Beach and Koala Pangkalpinang Beach. The study was conducted in April 2025 at two locations: Tanjung Bunga Beach and Koala Pangkalpinang Beach. The methods used in this study were descriptive methods and the sampling method employed was purposive sampling. The analytical method used to measure the concentrations of heavy metals Pb and Cu in sediment, roots and leaves of mangroves was Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The analysis results showed that the heavy metal Pb content in the roots, leaves and sediments of Sonneratia alba mangrove at Tanjung Bunga Beach was 0,614 mg/kg, 0,726 mg/kg and 15,7 mg/kg, respectively, while the heavy metal Pb content in the roots, leaves and sediments of Sonneratia alba mangroves at Koala Beach was 1,143 mg/kg, 0,270 mg/kg and 10,8 mg/kg, respectively. The results indicate that Sonneratia alba mangroves have only a slight ability to absorb heavy metals Pb and Cu.]]>
