Abstract

A review of the chemical abundances of Galactic H II regions is presented. The C and O abundances derived from recombination lines are higher than those derived from forbidden lines; arguments in favor of the recombination abundances are given. The Galactic abundance gradients are discussed. The M8, M17 and Orion abundances are compared with those of the Sun and with primordial abundances.
