摘　　要：选取中华圆田螺为受试动物,探究氟在其体内不同组织中的富集。结果显示,在不同浓度水氟环境条件下(0、40、80、160 mg/L)连续暴露10 d、20 d和30 d时,与对照组相比,中华圆田螺腹足中氟含量随着暴露时间的延长而逐渐升高;内脏团中的氟含量在10 d时无显著变化,在20 d和30 d时均显著高于对照组(P<0.05);随着暴露时间的延长,与对照组相比,生殖腺中的氟含量显著升高(P<0.05),而且在暴露20 d时,氟含量随着浓度的增加而明显增加,其后富集含量基本处于平衡状态。In the present study, the Cipangopaludina cahayensis was used as material to assess the tissues distribution of fluoride after short-term exposure. The Cipangopaludina cahayensis was exposed in the water containing 0, 40, 80 and 160 mg/L of fluoride for consecutive 10, 20 and 30 days, respectively. Compared with the control, the fluoride content in gastropods of Cipangopaludina cahayensis was increased with the extension of exposure duration. Although there were no significant differences in fluoride content in the visceral mass between the 10-day fluoride exposed Cipangopaludina cahayensis and control, significant differences were found between the 20--day and 30-day fluoride exposed Cipangopaludina cahayensis and control （P〈0.05）. With the extension of exposure duration, the fluoride content in gonad of exposed Cipangopaludina cahayensis was significantly increased compared with that of control （P〈0.05）. In the 20^th day of fluoride exposure, the fluoride accumulation was significantly increased with the increasement of water fluoride concentration, and
