摘　　要：γ—BHC在水体中消失一半所需的时间为16.8d.水生生物都能很快地从水体中吸收γ—BHC,并迅速达到最大体内浓度.其中,以鱼体内浓度最高,螺次之,浮萍和金鱼藻较少.γ—BHC在水生生物体内也能产生异构化,主要异构化产物为α、δ—BHC.但它们的异构化率都低于0.03%.It takes 16.8 days for γ-BHC to lose half of its quantity in aqueous phase. Aquatic orga nisms can quickly absorb γ-BHC from aqueous phase and reach the maximum concentration of γ - BHC in their bodies. Among others the concentration in Lemna minor L. and Antirrhinum majus L. is high, in Mararya melaniodes Neevill is higher, and in African Carassius auratu is the highest. The isomerization γ-BHC can emerge in aquatic organisms. Its products are mainly γ-BHC and δ-BHC, but the isomerization ratio is lower than 0. 03%.
