Abstract:
New determinations of chemical abundances for He, N, O, Ne, Ar and S
are derived for all galactic planetary nebulae (PNe) so far observed
with a relatively high accuracy, in an effort to overcome differences
in these quantities obtained over the years by different authors using
different procedures.
