The Ecological Risk Assessment of Mercury Contamination in a Mangrove Ecosystem of the Segara Anakan Cilacap, Indonesia

Ecological risk assessment of mercury contaminant has a means to analyze the ecological aspect ecosystem using potential impact pollution in soil, water and organism. The coastal area can be shown by mangrove zonation, clustering interpolation accumulation. This research aims (including bioaccumulation translocation) indicators species distribution, clustering, zonation results showed that Segara Anakan had high pollution, like as body was 0137±0.0137 ppm, substrate sediment were 0.0134±0.0212 ppm. To reduce could conducted planting, following ability accumulation stem bark between 0.011 0.064 roots 0.0260 0.0690 ppm leaves 0.0020 0.0120 ppm,. second indicator used factors, which range 0.0210 0.4751, translocation factors 0.0459 1.0547. also that: Avicennia marina, Sonneratia alba, Rhizophora apiculate, mucronata Nypa frutican good accumulate contamination.
