Expressions ae derived for the coefficients of the anomalous transport involving drift turbulence in toroidal geometry. The corresponding transport coefficients for the trapped particles are shown to be substantially higher than those for the untrapped particles. The transport processes involving trapped particles are distinguished by a thermal pinch in both the flux of trapped particles and the heat flux associated with these particles. The pinch effect in the particles depends only weakly on the width of the frequency spectrum of the drift waves. The thermal pinch falls off monotonically to zero as the spectrum becomes broader. It would seem that this behavior of the trapped particles might play an important role in shaping the ''consistent profiles'' in a tokamak.
