Abstract:
This study aimed to analyzes the content of heavy metals Cu and Pb in the roots, leaves and barks of R. mucronata and analyze the ability of R. mucronata in accumulating heavy metals. Sampling was carried out at Medan Labuhan Sub-District Nelayan Village and Jaring Halus Village, Secanggang District. The analysis of Cu and Pb heavy metals was carried out at the Research Laboratory, Faculty of Pharmacy, University of North Sumatera. Using the Atomic Absorption Spectrophotometer (AAS) method.The results of this study indicate that the heavy metal content of Cu on the barks and leaves in Jaring Halus Village are higher than Nelayan Village. The content of Cu in roots are higher in Nelayan Village. The content of Pb Metal in the barks and roots in Jaring Halus Village are higher than Nelayan Village. The content of Pb metal in the leaves are higher in the Nelayan Village. Based on bio concentration factors, R. mucronata's ability to accumulate Cu heavy metals are categorized as me
dium, whereas in accumulating Pb heavy metals are categorized as low.
