The Study on the Aluminum Content in Fishes Caught from Several Areas of the West Coast in Korea

수산식품 중 노인성 퇴행성 질환과 관련된 알루미늄 함량 및 그에 따른 수산식품의 이용방안에 관한 연구

This study was performed to determine the amount of aluminum, which is one of the factors of Alzheimer's disease, In some fishes caught from some areas of the west coast in Korea. The 46 aquatic products were composed of fishes, molluscs, and salt-fermented products (jeot-gal). The 24 fishes were Hickory shad, Gobies, Pomfref, Atkafish, Flounder, Jambeng-ie Monk fish, Yellow hair tail, Mackerel, Bartailed flathead, Alaska pollack, Brown croaker, Eel, Fine-spotted flounder, Black spotted grouper, Sea-eel, Pacific saury, Areliscus honaleus, Small boil-dried anchovy, Croaker, Hair tail, Sea bream genuine, Motleystrip rainbowfish, and Bastard halibut. The 15 Molluscs were Whip-arm octopus, Sea arrow, Common squid, Han chi, Cuttle fish, Turban shell, Pond snail, Orient calm, Surf calm, Butter calm, Crib shell, Oyster, Egg cockle, Little neck calm, and Arkshell. The 7 salt-fermented products were salt-fermented Shrimp, Little neck, Oyster, Shad, Gonjeng-ie, Hqangsegi, and Squid. All of them were ashed with 5$m\ell$ HNO$_3$ and then with 10$m\ell$ ternary solution (HNO$_3$ : H$_2$SO$_4$ : HClO$_4$= 10 : 1 : 4). After ashing of the samples, the aluminum amount were measured by ICP. The aluminum amount of molluscs was significantly higher than that of fishes and salt-fermented products(p＜0.01). The aluminum amount of Orient calm and Healak in molluscs were 827.70, 812.55ppm, respectively, which were the most amounts compared nth that of the other samples. But the aluminum amounts of Bartailed flathead and Sea bream, genuine In fishes were 0.98, 0.97ppm, respectively, which were the least amounts compared with that of other samples. This study was limited within 46 aquatic samples, therefore I hope there will be wider efforts to determine about auminum amount in broade range of aquatic foods for the prevention of Alzheimer's disease.

알루미늄 등 중금속 오염이 점점 심화되고 있는 서해안 일부지역에서 포획되고 있는 46종의 어패류 중 알루미늄 함량의 평균은 88.38$\pm$189.03ppm으로 그 범위는 0.97-827.70ppm이었는데 24종의 생선 중 알루미늄 함량은 그 범위가 0.97ppm에서 45.12ppm으로 건실치에 가장 많았고 도미에 가장 적게 함유되어 있었다. 15종의 연체류가 함유하고 있는 알루미늄 함량은 3.40ppm에서 827.70ppm으로 그 차이가 매우 컸는데 복족류인 소라에 3.40ppm으로 가장 적게 함유되어 있었고 이매패류인 대합에 826ppm, 해락에 812.55ppm으로 가장 많이 함유되어 있었다. 7종의 젓갈의 알루미늄 함량은 2.50-295.15ppm으로 그 차이가 컸는데 황새기젓과 한치젓에는 그 함유량이 낮았지만 조개젓과 곤쟁이젓에는 많은 양의 알루미늄이 함유되어 있었다 생선과 연체류 및 젓갈중에 함유되어 있는 알루미늄 함량간의 유의차를 검증한 결과 연체류의 알루미늄 함량이 생선과 젓갈에 비해 유의적으로 높았다(p＜0.01), 이는 일생동안 주거지를 크게 움직이지 않는 생육조건을 갖는 이매패류의 특성때문으로 사료된다.
