The potential of Avicennia alba blume in phytoremediation of heavy metal Pb and Cu in the area east coast mangrove forest Reserve Jambi, Indonesia

The Batanghari River is the fourth longest river in Indonesia, and along course of river, there are many community activities, such as fishing, coal-carrying, industrial activities. These various activities can cause contamination heavy metals lead (Pb) copper (Cu). This pollution be overcome by using phytoremediation techniques Avicennia alba Blume, which grows East Coast Mangrove Forest Reserve Area (CAHBPT), Jambi. study aims to determine potential mechanism Pb Cu A. at CAHBPT, Tanjung Solok, Jabung Timur, Sampling was done a purposive sampling method. showed that accumulation level metal sediments 10.08-13.42 mg/kg, 8.61-22.92 mg/kg. reducing impact classified an excluder marked BCF <1, even though concentration still below EPA quality standard threshold for sediments. Jambi, has translocation form phytoextraction characterized TF value >1, with phytostabilization <1.
