Abstract

Aquatic environment of Jakarta Bay have already been highlighted due to its heavy metals contamination which may lead into food safety concern of fisheries products derived from this region. This research aimed to investigate bioaccumulation level of heavy metals (Pb, Cd, and As) in fish and mussels from Jakarta Bay, as a human risk assessment of seafood consumption. Samples of mussels and fish were taken from Penjaringan, Tarumanegara, Cilincing, and Tanjung Pasir district. Bioaccumulation of heavy metals was analyzed by Inductively Coupled Plasma -Mass Spectrometry technique. Results of the study revealed that metals bioaccumulation in fisheries products were varied, with As (Arsenic) as the highest metal contaminant (0.68 mg/kg, dry weight). Furthermore, estimated daily intake (EDI), target hazard quotient (THQ), total target hazard quotient (TTHQ), and safety limits prescribed by various agencies, showed that consumption of fisheries products from Jakarta Bay considered as relatively safe for human health in total of food ingestion rate of fish 57.34 g/day. These results are expected to serve as a baseline to construct preventive and palliative policies for food safety of fisheries products from Jakarta Bay.

Abstract

The practice of formaldehyde abuse as a food preservative, especially in fishery products, is commonly occurred. However, the differentiation of the formaldehyde origin in fish is difficult to be performed. Meanwhile, physical observation is not sufficient to determine the additional formaldehyde in fishery products. This study aimed to formulate a quantitative method to detect the origin of formaldehyde in fish. The formulation was developed based on the differences in some chemical properties (Formaldehyde (FA), Trimethylamine (TMA) and Trimethylamine oxide (TMAO) of fish treated with and without formaldehyde addition. The fish used as samples were beloso fish/lizardfish (Saurida tumbil). Fish were prepared with and without the addition of  formaldehyde and  then stored in ice for 21 days. The content of FA, TMA, and TMAO of gill and flesh during storage were analyzed every 3 days to determine the difference in the trend of distribution patterns of two fish treatments. The data were statistically processed to produce two mathematical formulas to identify the origin  of formaldehyde. The results reveal that detection of the origin of formaldehyde in fish could be done using two approaches: the diffusion rate approach (validation 75-100%) and the ratio of formaldehyde, TMA, and TMAO (validation 96,47%).Keywords: Formaldehyde, fishery product, food preservative, mathematical formalulation, Surida tumbil
