Abstract

The heavy metal concentrations in dried seafoods commonly consumed in Gyeonggi-do were analyzed. Concentrations of lead (Pb), cadmium (Cd), mercury (Hg) and selenium (Se) were measured in 95 samples with an inductively-coupled plasma-mass spectrometer (ICP-MS) and an Hg analyzer. The average concentration [mean±SD(minimum-maximum) mg/kg] of heavy metals were as follows: Pb 0.062±0.071(0.002-0.428), Cd 0.083±0.100(0.004-0.540), Hg 0.012±0.012(N.D-0.054) and Se 0.839±0.371(0.362-2.124). All the levels were below the recommended standards of the MFDS (Ministry of Food and Drug Safety). In the comparison of heavy metal content by anchovy size, it was shown that mercury was significantly higher in large anchovy (P<0.05). Selenium levels were found to differ significantly in small anchovy and large anchovy (P<0.05). Pb, Cd and Hg were significantly higher in Tiger prawn among shrimp (P<0.05). The heavy metal and selenium levels of anchovy and shad were highest in the intestine. However, the heavy metal and selenium levels of shrimp were highest in the head. In addition, weekly (monthly) intake of mercury and cadmium from dried seafoods was found to be 0.712% and 2.978% of PTW(M)I (Provisional Tolerable Weekly(Monthly) Intake) respectively. Therefore, it was found that dried seafoods were safe for consumption.

경기도에서 유통되고 있는 건조수산물 95건에 대하여 유해중금속인 납, 카드뮴, 수은 및 미량영양소인 셀레늄 함량을 조사하였다. 금아말감법의 수은분석기, 유도결합플라즈마 질량분석기를 사용하여 측정하였으며, 각 항목별 평균함량은 납 0.062±0.071(0.002-0.428) mg/kg[평균값±표준편차(최소값-최대값) mg/kg], 카드뮴 0.083±0.100(0.004-0.540) mg/kg, 수은 0.012±0.012(N.D-0.054) mg/kg, 셀레늄 0.839±0.371(0.362-2.124) mg/kg으로 나타났으며, 유해중금속인 납, 카드뮴, 수은 모두 기준규격 이하로 나타났다. 멸치 크기에 따른 중금속 및 셀레늄 함량은 수은이 대멸치에서 통계적으로 유의하게 높게 나타났으며(P<0.05), 셀레늄은 잔멸치와 대멸치의 크기에 따른 유의적인 함량 차이를 나타냈다(P<0.05). 새우 종류에 따른 중금속 및 셀레늄 함량을 비교한 결과 보리새우가 납, 카드뮴, 수은에서 유의적으로 높게 나타났다(P<0.05). 대멸치, 밴댕이의 부위별 중금속 및 셀레늄 함량은 내장부위가 가장 높았고, 새우는 머리부위가 중금속 및 셀레늄 함량이 높게 나타났다. 건조수산물을 통해 섭취하는 수은, 카드뮴의 주간 및 월간섭취량은 JECFA에서 설정한 PTW(M)I의 0.712%와 2.978%로 조사된 건조수산물 내 중금속 함량은 안전한 농도수준으로 판단된다.
