Abstract
The aim of this study was to determine total mercury and methyl mercury level in fishes (Deep-sea Fish, Tuna, Billfish) and fishery products. A total of 101 fishes and 44 fishery products samples collected from commercial market in Gyeonggi-do. Total mercury were analysed by mercury analyzer and methyl mercury were analyzed by gas chromatography with electron capture detector. In the fishes, total mercury was detected in all samples and methylmercury was detected in 92 samples of them. The detection rate of methylmercury was 91.1% in fishes. The mean concentration (mg/kg) of total mercury and methylmercury were $1.968{\pm}0.505/0.496{\pm}0.057$ for Billfish, $0.665{\pm}0.091/0.252{\pm}0.033$ for Deep-sea Fish and $0.577{\pm}0.085/0.218{\pm}0.025$ for Tuna, respectively. The Swordfish contains the highest level of total mercury (1.968 mg/kg) and methylmercury (0.496 mg/kg). In Mabled rockfish, the ratio of methylmercury's contents about total mercury's contents was the highest as 66.5%. In case of fishery products, frozens made of 100% of raw material contained the highest level of total mercury and methyl mercury. The weekly intake of total mercury and methylmercury was calculated in 4.72% and 5.24% of Provisional Tolerable Weekly Intake (PTWI) respectively. This study showed that the weekly intake of methylmercury from Deep-sea Fish, Tuna and Billfish was less than the PTWI recommended by the Joint FAO/WHO expert committee on food additives.
