본 연구는 바지락, Ruditapes philippinarum의 체내 미량금속 농도, 이성생식세포 발현과 소화선의 조직학적 지표 변화를 이용하여 이들의 안정성을 알아보고자 하였다. 시료는 2010년 5월 한국 남해안의 가막만 3곳에서 채집하였다. 금속이온의 체내 축적 농도는 분석된 10가지 금속 이온 가운데 Al이 가장 높았으며, 두 번째로 Zn이 높았다. 그리고 Co가 가장 낮은 농도로 나타났다. 이성생식세포 발현율은 18.5%로 나타났으며, 암컷에서 더 높았다. 이성생식세포 발현 형태는 한 가지 형태가 관찰되었다. 조직학적 지표는 소화선의 조직학적 변화, 호염기성세포와 지방갈색소의 분포비율을 이용하였다. 소화선에서는 소화선세관 상피층의 파괴가 가장 높은 비율로 나타났다. 호염기성세포의 분포 비율은 5.8%로 나타났고, 지방갈색소 분포 비율은 1.8%였다.
This study investigated concentration of heavy metals, intersexuality and histological alterations of digestive gland in Ruditapes philippinarum. Samples were collected from three areas of Gamak Bay in May, 2010. The concentration of trace metals showed that Al was highest, Zn was second high concentration and the lowest concentration was Cd. The intersexuality was 18.5% and female was higher than the male. Intersex type was observed one types. Destruction of digestive tubule epithelium was highest among other biomarkers in digestive gland. Distribution of basophilic cell was 5.8% and lipofuscin was 1.8%.
