Bioconcentration of Plumbum (Lead) and Cadmium on mangrove crab Scylla spp. in mangrove ecosystem Passo Ambon Indonesia

Abstract Mangrove crab ( Scylla spp.) is one of the potential fishery commodities Maluku Province, which in high demand because delicious and nutritious has selling export value. This research conducted on Passo mangrove ecosystems, May-July 2021. The aims were to analyze concentration heavy metals Pb (lead) Cd (cadmium) water, sediment crabs; bioconcentrations its pollutant categories. Samples crabs taken captured ecosystems (Station 1) at three substations using purposive sampling method. treatment water samples, from nature follows standards handling samples for analysis metal concentrations each medium. medium was analyzed an Atomic Absorption Spectrophotometer. results showed that value still detection limit; sediments have exceeded crabmeat limit. limit value; while relatively low but indicated accumulation. Bioconcentration Factor indicates accumulation PB (<100).
