The physical conditions and chemical composition of the interstellar medium in line to HD 93205, an O3V star in the Great Carina Nebula, were studied, using UV spectra. The two main high velocity components show different relative abundance patterns. The red shifted component shows no depletion. For the blue shifted component, the relative abundance pattern seems difficult to explain in terms of elements locked into grains. Its composition is attributed to mixing with freshly synthetized material ejected by a recent supernova explosion. One low velocity component is identified with the normal interstellar gas in the disk of the Galaxy. In this component, column densities of interstellar CIV and SiIV, free from contamination by circumstellar material, were measured. The other low velocity component is identified with the approaching part of the expanding ionized nebula around the Carina OB associations. It consists of a dense HII region in which the two conspicuous OI fine structure lines originate.
