Abstract
The metal content of the spiral galaxy M33 is analyzed through spectroscopic observations of its emission-line populations, H ii regions and Planetary Nebulae (PNe): their abundance gradients are identical within the errors. The 2D metallicity map is presented, finding an off-center peak, located in the southern arm. A chemical evolution model of M33 described by Magrini et al. (2007a) is updated at the light of recent results on the Schmidt law and the metallicity gradients.
