Longitudinal ion viscosities, heat conductivities and thermal diffusion ratios in magnetised D-He and H-C plasmas are calculated within Grad's 21- moment approximation. Calculations taking full account of the finite mass ratio m(+)/m(Z) between hydrogen (deuterium) and impurity ion mass are compared with those for m(+)/m(Z) very much less than 1. As is to be expected, the largest discrepancies between exact and approximate results (with respect to the mass ratio) arise for D-He plasmas. The approximate formula for the impurity ion heat conductivity has to be extended to remove existing deficiencies.
