The equivalent width, W, of the Na I D lines in 41 globular clusters with reddening E(B-V) = 0-1.11 and a wide spatial distribution in the Galaxy is studied. The relationship between interstellar Na I and E(B-V) presents a steeper slope for globular clusters than that derived for stars in the solar neighborhood. In view of stellar population synthesis in galaxies, the age and metallicity effects in the W(Na I) vs W(Mg I) plane are studied by means of 15 Magellanic Clouds and 3 Galactic open clusters. Also analyzed are 154 normal and 11 active galactic nuclei. It is found that the Na I line is enhanced with galaxy inclination in spirals and very metallic early type galaxies deviate from a linear relationship in the W(Na I) vs W(Mg I) plane.
