Spiral galaxies tend to have concentrations of heavier elements. This is because the spiral arms are "density waves" that sweep through the galaxy, disturbing gaseous nebula and fostering active star formation. As stars age, they create heavier elements (anything more complex than hydrogen and helium) and as the die they spread them around, to be used in the next generation.
Elliptical galaxies have star formation, but not nearly as active as spiral galaxies. As such they have much more basic compositions, almost entirely hydrogen and helium.
