Abstract
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 $HNO_3$ and then wet-decomposed with 10 ml of a mixture of $HNO_3:H_2SO_4:HClO_4$ (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.
