| Abstract |
We compare the abundances of He, N, O, Ar, S, and Ne, determined in a similar way, for a sample of Galactic bulge and disc planetary nebulae (PNe). We find that in all aspects – average abundances and dispersion, distribution functions, abundance relationships, and the ratio of N/O – the bulge and disc PNe are indistinguishable. The nebular distribution of [O/H] is different to the stellar. |
