Scientific paper

Recent applications of PN to the study of galactic chemical evolution are
reviewed, such as PN and stellar populations, abundance gradients, including
their space and time variations, determination of the He/H radial gradient and
of the helium-to-metals enrichment ratio, and the [O/Fe] x [Fe/H] relation in
the solar neighbourhood and in the galactic bulge.
