ACCUMULATION OF Pb AND Cu METALS IN BLUE SWIMMER CRABS (PORTUNUS PELAGICUS) IN THE COASTAL AREA OF BANYUASIN, SOUTH SUMATRA

Abstract

The coastal area of Banyuasin is an area that has great fishery potential in South Sumatra Province. The dense traffic of ships and agricultural activities can cause waters to be polluted by heavy metals. This study aims to determine the concentration of Pb and Cu metals in blue swimming crabs caught on the Banyuasin Coastal Waters and compare it with existing quality standards. Sampling was carried out on the Banyuasin Coastal Waters using the fishing survey method. Samples were analyzed with AAS according to SNI 2354.5:2011 for Pb and SNI 2354.13:2014 for Cu. The results showed that the concentrations of Pb and Cu in the blue swimming crab meat were 0.62–2.48 mg/kg and 2.5-11.6 mg/kg, respectively. Based on the quality standards by BPOM No. 5 (2018) and SNI 7387: 2009, the concentration of Pb has exceeded the threshold; however, based on FAO (1983), only station 4 has exceeded the quality standard. The concentration of Cu in blue swimming crab meat is still below the quality standard, except at station, which exceeds the FAO quality standard (1983).
