EDCs 오염 하천수에 노출된 붕어, Carassius auratus의 생존율과 혈액학적 변화

Survival Rate and Hematological Change of the Crucian Carp, Carassius auratus Exposed to EDCs-polluted Stream Water

본 연구는 붕어, Carassius auratus의 생존율과 혈액학적 성상에 미치는 EDCs combination effect를 알아보기 위하여 수행하였다. EDCs-polluted water는 낙동강 구미 공업단지 하류에서 채수하였다. 실험구는 대조구와 3개 (50, 75 및 100%)의 EDCs-polluted water였으며, 실험기간은 16주였다. 생존율은 75%와 100% 농도구에서 대조구에 비해 유의적으로 감소하였다 (P<0.05). 혈액학적 성상은 대조구에 비해 100% 농도구에서 GOT, GPT, LDH 농도는 유의적으로 증가하였다 (P<0.05). 본 연구 결과, EDCs-polluted water는 붕어의 생존율 감소와 혈액학적 성상의 변화를 유도함이 확인되었다.

This study aims to find out the EDCs (endocrine disrupting chemicals) combination effect on survival rate and hematological characteristics of the crucian carp, Carassius auratus. EDCs-polluted water was collected from downstream of the Gumi electric industrial complex of the Nackdong River. The experimental groups were composed of one control condition and three EDCs-polluted water conditions (50, 75 and 100%). The experimental period was 16 weeks. The survival rates of 75% and 100% exposure group were significantly decreased relative to the control (P<0.05). The concentrations of GOT, GPT and LDH in 100% exposure group were significantly increased relative to the control (P<0.05). The results of this study suggest that EDCs-polluted water induces reduction of survival rate and change of hematological characteristics in the crucian carp.
