It is shown that ambipolarity of turbulent particle fluxes (when properly defined) holds under very general conditions relevant to toroidal confinement devices. The results are classical analogues of quantum mechanical conservation principles and are consequences of the conservation properties of collision terms which occur in classical kinetic equations. It is also shown under conditions prevailing in toroidal devices, both compressibility and nonlinearity of the turbulent fluctuations play an important role in determining particle fluxes. The significance of the results demonstrated here for any future nonlinear theory of turbulent plasma transport is briefly discussed.
