摘要

研究发现，铅离子和表面活性剂壬基酚醛氧基酸盐可抑制林蛙腿部皮肤的主动运输耦合水流。在高渗流条件下，渗透驱动渗流的渗透率保持不变，在接近零渗透压差时，渗透率显著降低。结合污染物电生理效应的现有资料，讨论了渗透率变化的可能机制。

Membrane water permeability alterations induced by pollutants.

Lead ions and the surfactant nonylphenolethoxylate are found to inhibit the active transport-coupled water flow in the leg skin of Rana esculenta. The water permeability for osmotically driven flows remains unchanged for high flows, while it is remarkable lowered near zero osmotic pressure difference. The possible mechanism of the permeability change is discussed in connection with the available data on the electrophysiological effects of the pollutants.
