초록

본 연구에서는 생산 지역이 한정되어 있고, 맛이 뛰어나 소비자들이 선호하고 있는 영덕대게와 러시아산 대게의 효율적 이용과 식품위생학적 안전성 및 먹이사슬을 통한 미량금속의 순환 연구에 기초자료를 제공하기 위하여 영덕대게(수컷, 암컷)와 러시아산 대게의 부위별 니켈, 구리, 아연, 카드뮴, 납, 비소, 크롬의 농도를 ICP-MS로 분석하였다. 인증표준물질(certified reference material, CRM)을 사용한 각 금속에 대한 회수율은 평균 81~99%로 Codex에서 요구하고 있는 수준에 부합하였다. 영덕대게의 부위별 금속 농도는 수컷과 암컷의 껍질에서는 Ni > As > Zn > Cu > Cr > Cd, 다리살은 Zn > As > Cu > Cr > Ni > Cd, 몸통살은 Zn > As > Cu > Cr > Cd > Ni, 아가미는 Cu > Zn > As > Cd > Cr > Ni 순으로 같았으며, 내장에서 수컷은 Cu > As > Zn > Cd > Ni > Cr, 암컷은 Cu > Zn > As > Cd > Cr > Ni 으로 다소 차이가 있었다. 러시아산대게는 카드뮴을 제외한 모든 금속류(니켈, 구리, 아연, 비소, 크롬)의 농도가 영덕대게와 비슷하거나 다소 낮게 나타났지만, 카드뮴 농도는 모든 부위에서 높게 나타났다. 특히, 내장에서는 약 2배, 아가미에서는 약 4배 높게 나타났다. 영덕대게의 크기별 미량금속 농도변화에서 부위별로 가장 농도가 높은 금속류(껍질의 Ni, 다리살과 몸통살의 Zn, 내장과 아가미의 Cu)들은 전반적으로 성장할수록 감소하는 경향이 있는 반면, 내장에 가장 많이 축적되어 있는 카드뮴의 농도는 전반적으로 증가하는 경향이 있으며, 성장과 더불어 내장 내 생물축적현상이 가중될 가능성이 있다.

This study is to measure the differences of the trace-metals resulted from the different ecologies, such as nickel(Ni), copper(Cu), zinc(Zn), cadmium(Cd), plumbum(Pb), arsenic(As) and chrome(Cr) remaining in the parts of Korean Yeongdeok Crab (KYC) and Russian Snow Crab (RSC) based on ICP-MS. The recovery rate of each metal certified the reference materials (CRM) was in the average of 81~99%, which corresponded with the level required in Codex. The level of metals in the parts of KYC was in the order of Ni > As > Zn > Cu > Cr > Cd in the both male and female shell; the order of Zn > As > Cu > Cr > Ni > Cd in the leg flesh; the order of Zn > As > Cu > Cr > Cd > Ni in the body flesh; the order of Cu > Zn > As > Cd > Cr > Ni in the gill; the order of Cu > As > Zn > Cd > Ni > Cr in the male hepatopancreas; the order of Cu > Zn > As > Cd > Cr > Ni in the female hepatopancreas, thereby showing some differences. It was revealed that the levels of most metals (nickel, copper, zinc, arsenic and chrome) were similar between KYC and RSC except cadmium which was somewhat lower than that of KYC. However, the cadmium in RSC was discovered in high level in most of the parts, two times higher in the hepatopancreas, and four times in the gill. It was also revealed that the trace metal contents were changing according to the size of KYC; the metals with the highest level of Ni in shell, Zn in leg and body flesh, Cu in gill tended to decrease as growing, whereas the cadmium contents tended to increase overall and accumulated the most in hepatopancreas. The results showed there was a possibility that the phenomenon of bioaccumulation within hepatopancreas would increase as growing.
