Abstract
The origin of the abundance discrepancy in nebulae is one of the key problems in the physics of photoionized nebulae. In this work we have analized a sample of Galactic and extragalactic H II regions where the abundance discrepancy have been measured, and we discuss the two main scenarios proposed to explain such discrepancy: temperature fluctuations over the observed volume of the nebulae and chemically inhomogeneous inclusions.
