Abstract

Increasing number of industries and settlements in Banten Bay were subsequently followed by an increase in the amount of waste, whether in the form of solid, liquid or gas that can pollute the environment. One of the toxic pollutants is heavy metal.The entry mechanism of the heavy metal Mercury (Hg) and Lead (Pb) in body of the crab (Portunus pelagicus), namely through the process of digestion food. This study was conducted for 6 months, from March to August 2019, and aimed to analyze the heavy metal content levels (Pb and Hg) and the safe consumption level of the blue swimming crab (Portunus pelagicus) in the waters. The heavy metal concentration in the meat was measured through the AAS (Atomic Absorption Spectrophotometer) AA 7000 series Shimadzu. The analysis showed that the Pb and Hg contained in the blue swimming crab were still under the quality standards. Also, the bio-concentration factors of the blue swimming crab were low (<100).  Water quality data observed as temperature, salinity, TSS, pH, dissolved oxygen, turbidity, and transparency stayed in the range of tolerable limits for the survival of marine organisms. Maximum weekly intake calculation refers to the tolerable limits issued by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). The JECFA recommends calculating the PTWI of each heavy metal if it accumulates in the human body for methyl mercury 1.6 μg.kg bw.week-1 and for lead not exceed 25 μg.kg bw.week-1. The safety consumption level of blue swimming crab from Cengkok Coastal water was 2.3 kg of meat.week-1 (for adults) and 0.6 kg of meat.week-1 (for children).

Abstract

Banten Bay is a developing area that is used by various activities such as fishing ports, industry and hotels. Many activities in the coastal areas of Serang City and Cilegon Regency have a serious impact on the quality of waters and fishery resources along Banten Bay. This study aims to analyze and determine maximum tolerance limit for bandik grouper (C. boenak) meat and gills which are safe for consumption by adults and children. The study was conducted at six stations, namely Panjang Island and Pamujaan Besar Island during the period of May, June and July 2019. Measurement of heavy metal content on meat and gills carried out using Atomic Absorption Spectrophotometric (AAS). The content of Pb and Cd in water fluctuates. The metal content of Pb and Cd in the meat and gills of bandik grouper has exceeded the quality standards set by BPOM and FAO/WHO, and is classified as polluted mild to moderate Pb bioconcentration factor values in grouper meat ranged from 6.78-72.00 and Pb bioconcentration in grouper gills 32.86-762.61. The maximum weight of grouper meat that can be tolerated for consumption for adults is 3,5 kg/week and children 1.0 kg/week.
