Abstract
Lead ions and the surfactant nonilphenolethoxylate 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 remarkably 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.
