서해안 일부지역에서 채취되는 어패류를 동결 건조한 후 ICP-AES분석법을 이용하여 수분함량, 크롬과 코발트함량을 측정하였다. 그 결과 수분함량은 연체류>어류>갑각류 순이었고 연체류의 수분함량은 갑각류에 비해 유의성있게 높았다. 어류, 연체류 및 갑각류간의 크롬함량은 유의성을 나타내지 않았으나 코발트함량은 갑각류가 어류나 연체류에 비하여 유의적으로 높았다. 그리고 어패류 중에 존재하는 크롬과 코발트함량 사이의 연관성은 없는 것으로 나타났다. 특히 연체류중의 크롬함량이 422ppm으로 가장 높이 존재하는 것은 피조개였고, 박대, 맛살 및 보리새우는 어류, 연체류 및 갑각류 각각에서 크롬과 코발트의 함량이 모두 높은 시료임을 확인 할 수 있었다.
This study was performed to assess the levels of the Cr and Co in fisheries caught from the some areas of west coast in Korea. The samples were 26 kinds of fishes, 19 kindly of Mollusca and 3 kinds of Crustacea. They were ashed with 5 ml <TEX>$HNO_3$</TEX> and then wet-decomposed with 10 ml of a mixture of <TEX>$HNO_3:H_2SO_4:HClO_4$</TEX> (10:1:4). After ashing of samples, the amounts of Cr and Co in the samples were determined by ICP-AES analysis. The moisture content of molluscans was significantly higher than that of crustaceans (p<0.05), but there was no significant difference among fisheries in the Cr content. And the Co content of crustaceans was significantly higher than that of fishes and molluscans (p<0.001). There was no significance between contents of Cr and Co in fisheries. The Cr content of Arkshell was 422.00 ppm, which was the most amount compared with those of the other samples. And the Co in Myong-Ge was 3.78 ppm, which was the most amount. Areliscus honaleus (Cr:2.76 ppm, Co:0.97 ppm), Solen (Cr:6.56 ppm, Co:1.59 ppm) and dried barley shrimp (Cr:1.06 ppm, Co:0.90 ppm) contained great amount of Cr and Co.
