    The experimental data of heat of transport Q* and effective charge Z* of protium, deuterium and tritium in vanadium, niobium and tantalum recently measured by the present authors are summarized for comparison. The data of Q* show a definite mass and element dependence whereas those of Z* do not show such a trend. Simple correlation of mass and element dependence between Q* and Z* is not found out by direct comparison of these data. Similarities of the atomistic origins between Q* and Z* are discussed, in particular the screening effect due to electrons is discussed by correlating the atomistic interpretation of the mass and element dependence of Q* with the interpretation of the direct charge.
