Abstract

The Factories that stand around the mangrove area of the Percut Sei Tuan allow the occurrence of waste disposal included heavy metals into the aquatics. One of the heavy metals found in these aquatics were Plumbum (Pb). The aim of this research to determined the concentration of lead Pb on roots, leaves and stem barks of Avicennia marina and to determined the ability of mangrove vegetation to accumulated heavy metals of lead Pb in the area of the Percut Sei Tuan. Heavy metal concentration of lead (Pb) on roots, stem barks, and leaves were 4,83 mg/kg, 0,805 mg/kg, and 1,31 mg/kg. The concentration of heavy metal lead (Pb) on water and sediments were 0,09 mg/l and 14,3 mg/l. It show that A. marina was able to accumulating heavy metals Pb on roats, stem barks and leaves, and was not exceeding the estabilished quality standart.Keywords: Percut Sei Tuan, Heavy Metals , Plumbum (Pb), Avicennia marina
