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.

본 연구의 목적은 경기도 내 유통되고 있는 수산물(심해성 어류, 다랑어류 및 새치류) 및 어류가공품의 총수은 및 메틸수은 오염도를 알아보기 위해 실시하였다. 수산물 101건과 어류가공품 44건을 수거하여 수은분석기 및 가스크로마토그래피 전자포획검출기를 사용하여 분석하였다. 수산물은 모두에서 총수은이 검출되었고 메틸수은은 92건에서 검출되어 91.1%의 검출률을 나타내었다. 총수은과 메틸수은의 함량은 각각 새치류 $1.968{\pm}0.505$, $0.496{\pm}0.057mg/kg$, 심해성어류 $0.665{\pm}0.091$, $0.252{\pm}0.033mg/kg$, 다랑어류 $0.577{\pm}0.085$, $0.218{\pm}0.025mg/kg$순으로 높게 나타났으며, 황새치의 평균값이 총수은은 1.968 mg/kg, 메틸수은은 0.496 mg/kg으로 가장 높았다. 총수은 대비 메틸수은 함량은 심해성 어류인 쏨뱅이류가 66.5%로 가장 높았다. 어류가공품의 총수은 메틸수은함량은 원육함량 100%인 냉동식품이 가장 높았으며 원재료 함량과 비례하여 나타났다. 심해성 어류, 다랑어류 및 새치류를 통한 총수은 및 메틸수은의 주간섭취량은 JECFA에서 설정한 PTWI의 4.72, 5.24%로 조사된 어류를 통한 우리나라 국민들의 노출량은 안전한 것으로 나타났다.
