Evolved massive stars in giant H II regions: the chemical enrichment prior to SN events.
Massive stars have significant effects on the ambient interstellar medium (ISM) via either strong UV radiation or powerful stellar winds. These winds also produce an important chemical pollution. Since WRs are the chemically evolved descendants of very massive stars, their winds are expected to be helium-rich and to show the effects of the CNO
