Models for chemical evolution and stellar abundances are used to test assumptions about the nucleosynthesis of various elements. For primary elements, the emphasis is on empirical evidence that carbon and iron, but not oxygen, are ejected in significant quantities by longer-lived stars than those proposed by Arnett for their entire nucleosynthesis, which all have lifetimes <2 x 10/sup 7/ years.
