Scientific paper

Damped Ly-α (DLA) systems are responsible to the strongest absorption in quasar spectra, and it is traditionally assumed that DLA systems are progenitors of present day galaxies. In this work we deal with spiral galaxies, considering the hypothesis that spirals from early to late types may represent part of observed DLA systems. We present a one-zone chemo-spectrophotometric evolution model of spiral galaxies with self-consistent inclusion of dust evolution, and compare chemical evolution of spiral galaxies corrected for the dust depletion with chemical abundances observed in DLA systems over available redshift range.
