Description:
We report new spectroscopic observations for a sample of "bona fidae"
type I planetary nebulae, which satisfy kinematical, distance to the
galactic plane and morphological criteria. Special care was taken to
estimate physical parameters as electron temperature and density. The
mean sample oxygen abundance ε(O)=8.64±0.23 confirms our
earlier results: a deficiency of about 0.25dex with respect to the
solar value. We emphasize that the present result is entirely
compatible with new stellar (Cunha & Lambert 1994ApJ...426..170C 1994ApJ...426..170C)
and diffuse gas data (Meyer et al. 1994ApJ...437L..59M 1994ApJ...437L..59M) recently
obtained in the Orion complex.
