Abstract

Radial and vertical gradients of He/H, O/H, N/H, N/O, S/H and C/H are studied, considering a sample of 40 type II galactic planetary nebulae, with known abundances and distances. Radial gradients have been detected for He/H and O/H, for which reliable abundance determinations are available.
