Knowing the chemical composition of interstellar gas is essential for understanding the chemical evolution of galaxies. Ionized nebulae provide key laboratories for this purpose, where chemical abundances are commonly derived from emission lines of heavy ions such as doubly ionized oxygen, $O^{++}$.
