The relations of element depletions with E(B-V), and such other possible relations with two stellar parameters as mass loss rate and rotational velocity, are investigated in 14 O-type stars with high-resolution SWP spectra. The stars were chosen so as to cover several directions in the Galaxy as well as a wide range in interstellar reddening and, although the data used are crude and obtained through approximations, they show the derived dependence of a parameter on reddening, or 'depletion index'. An inverse trend relating the abundance of elements to interstellar reddening is found, and a crude relation between increasing depletion and condensation temperature is determined.
