This research was conducted in Nipah’s Mangrove, Sei Nagalawan Village, Serdang Bedagai North Sumatera. The analysis of using heavy metals is conducted in research centre and industrial standardization, Medan by using the Atomic Absorption Spectroscopy method. The result of this research showed that the highest content of heavy metal in the roots, barks and leaves are 0,05 mg/kg , 0,06 mg/kg and 0,008 mg/kg, respectively. Therefore the ability of A. marina in accumulating heavy metal Pb is classified very low.Keyword: : Avicennia marina, AAS, Heavy Metal, Plumbum (Pb), Kampung Nipah
