Heavy metals have non-biodegradable, toxic and accumulative properties in the environment. Heavy metals that enter water bodies will be carried by the flow towards the coast. Zinc (Zn) is one of the metals found polluting the waters in the city of Surabaya, Indonesia. One of the efforts to overcome this problem is the use of mangroves as phytoremediation agents. The purpose of the study was to determine the ability of Avicennia marina (Forssk.) Vierh in the Wonorejo Ecoforest to accumulate Zn by determining the bioconcentration factor (BCF) and the translocation factor (TF). Determination of the sampling points of this study using the transect method. Samples were taken in the form roots, stems, and leaves of mangrove plants and those were analyzed for Zn concentration using an atomic absorption spectrophotometer (AAS). Based on the result, A. marina showed the immobilized of Zn in root due to the BCF value was higher than 1. In conclusion, A. marina have potential to be phytoremediation plants in coastal area.
Key words: Avicennia marina (Forssk.) Vierh / heavy metal polution / phytoremediation / white mangrove
