본 연구는 납에 노출된 바지락, Ruditapes philippinarum 의 생물학적 반응을 알아보고자 하였다. 실험기간은 4주였으며, 실험구는 대조구 1개와 납 노출구 3개 (0.25, 0.50 and 1.00 mg/l) 였다. 실험 결과 납은 바지락의 생존율과 산소 소비율의 저하 및 기관계의 조직학적 변성을 유도하는 것이 확인 되었다. 납 노출구에서 산소소비율은 25-72% 감소하였다. 기관계의 조직학적 분석 결과, 외투막 상피층과 결합조직층의 변성, 아가미 점액세포의 증가와 상피세포의 괴사, 발에서는 상피층의 붕괴, 점액세포의 감소 및 혈림프동의 확장과 결합조직층의 변성을 나타냈다. 소화맹낭의 소화선세관에서는 호염기성세포와 상피세포의 위축 및 농도 의존적으로 lipofuscin의 축적이 확인되었다.
This study was conducted to find out biological response of Manila clam, Ruditapes philippinarum exposed to lead (Pb). Experimental period was four weeks. Experimental groups were composed of one control condition and three lead exposure conditions (0.25, 0.50 and 1.00 mg/l). The results of the study confirmed that lead induces reduction of survival rate and oxygen consumption rate and histopathology of organ structure of the bivalve. Oxygen consumption rate was observed exposure groups lower than control decline by 25%-72%. Histological analysis of organ system illustrated expansion of hemolymph sinus, disappearance of epidermal layer and degeneration of connective tissue layer of the mantle. Also, histological degenerations as epithelial necrosis and hyperplasia of mucous cells are recognized in the gill and it was observed expansion of hemolymph sinus, disruption of epithelial layer, decrease of mucous cell and degeneration of connective tissue layer in the foot. In the digestive diverticulum, it was showed atrophy of basophilic cell and degeneration of epithelial cell in the digestive tubules, and as the concentration of lead increased the accumulation of lipofuscin increased.
