Particle transport due to Ion Temperature Gradient/Trapped Electron (ITG/TE)mode turbulence is investigated using the gyrokinetic code GENE. Both a reducedquasilinear (QL) treatment and nonlinear (NL) simulations are performed fortypical tokamak parameters corresponding to ITG dominated turbulence.  A selfconsistent treatment is used, where the stationary local profiles arecalculated corresponding to zero particle flux simultaneously for electrons andtrace impurities. The scaling of the stationary profiles with magnetic shear,safety factor, electron-to-ion temperature ratio, collisionality, toroidalsheared rotation, triangularity, and elongation is investigated. In addition,the effect of different main ion mass on the zero flux condition is discussed.  The electron density gradient can significantly affect the stationaryimpurity profile scaling. It is therefore expected, that a selfconsistenttreatment will yield results more comparable to experimental results forparameter scans where the stationary background density profile is sensitive.This is shown to be the case in scans over magnetic shear, collisionality,elongation, and temperature ratio, for which the simultaneous zero fluxelectron and impurity profiles are calculated.  A slight asymmetry between hydrogen, deuterium and tritium with respect toprofile peaking is obtained, in particular for scans in collisionality andtemperature ratio.
