Popis: Classical Cepheids are the most popular primary distance indicator. They allow us to determine the Galactic abundances gradients and to constrain the chemical enrichment of the thin disc. We present here results based on high resolution spectra of 63 Cepheids. They indicate local abundances inhomogeneities in the outer disc (Rg >10 kpc).
