This paper reviews the various processes that have been proposed to explain the observedtrend of PAH strength with metallicity. It summarizes a study showing that, although PAHdestruction by hard radiation is important in low-metallicity environments, it is notsufficient to explain their paucity. In these systems, the deficiency of their formationmechanism, related to stellar evolution, has to be invoked.
