摘　　要：2002年3月和10月分别在广东省惠州港和南澳岛采集褐棘螺(Chicoreusbrunneus)和亚洲棘螺(C.asianus)。解剖观察发现这2个采样点2种棘螺的雌性个体都发生了性畸变现象。惠州港的棘螺已畸变到雌性个体不育的地步,这表明由于有机锡污染引起的性畸变现象对棘螺的生殖已造成严重的影响,并有可能导致棘螺的区域性灭绝。Specimens of Chicoreus brunneus and C. asianus were collected from Huizhou Harbor and Nanao Island of Guangdong in March and October of 2002, respectively. All the female individuals were found to be imposex, and sterile ones were distinguished from the specimens of Huizhou Harbor. These results indicated that the imposex, induced by organotin compound pollution, has brought great adverse effects on the reproduction of Chicoreus spp. and may lead to the extinction of the population in specific area.
