본 연구는 염화아연 만성노출에 따른 북방전복의 미량금속 축적 농도, 생존율, 탈락률 및 조직학적 지표 변화에 대하여 알아보고자 하였다. 실험은 1개의 대조구와 4개의 노출구 (0.3, 0.8, 1.3, <TEX>$1.8\;ZnCl_2\;mg/L$</TEX>) 였다. 염화아연에 노출된 북방전복의 체내 미량금속 축적 농도는 모든 노출구에서 농도의존적으로 증가하는 결과를 보였다. 생존률 및 탈락률은 대조구에 비해 노출구에서 농도의존적으로 나타났다. 북방전복의 발, 아가미, 간췌장의 조직학적 변화는 시간이 경과함에 따라 대조구에 비해 노출구에서 뚜렷하게 나타났다.
This study was conducted to find out concentration of trace metal, survival rate, falling rate and structural changes of abalone, Haliotis discus hannai exposed to zinc chloride. Experimental groups were composed of one control condition and four exposure conditions (0.3, 0.8, 1.3, 1.8 ZnCl2 mg/L). The accumulation of trace metal (zinc) in abalone was significantly increased all exposure group. Though the exposure groups had lower survival rate than the control group, higher falling rate than the control group. Histopathological changes in the foot, gill and hepatopancreas of abalone revealed obvious with exposure group than control group.
