Abstract :
We discuss the relations between the metallicity gradients and the other characteristics of a set of dwarf elliptical galaxies in different environments†. We suggest that dEs have typically metallicity gradients of −0.30±0.25 dex/re , unrelated to their mass. Dwarf elliptical galaxies with embedded disks, or dS0, may have flat metallicity gradients.
