Abstract

We have studied the interstellar column densities of AlII, SiII, SII, FeII, NiII, and ZnII in the direction of 18 O- and 6 B-type stars so as to improve the relations of element depletions with E(B-V), and to look for other possible relations with two stellar parameters: namely, the rate of mass loss and rotational velocity. The stars were chosen in order to cover several directions in the Galaxy, as well as a wide range in interstellar reddening. We found a clear inverse trend relating the abundance of elements to interstellar reddening.
