We present a model which allows for a self-consistent calculation of spectrophotometric, chemical, and dust evolution of spiral and irregular galaxies. Dust evolution is treated without the Instantaneous Recycling Approximation on the basis of the Dwek (1998) model, where up-to-date dust yields for SNe and intermediate mass stars on their AGB phase are taken into account. Confronting model results with the chemical abundances observed in DLA systems, we conclude that spiral and irregular galaxies are good candidates for DLAs.
