We have performed IUB observations of interstellar zinc toward 10 stars. We find that zinc is at most only slightly depleted in the interstellar medium; its abundance may serve as a tracer of the true metallicity in the gas. The f local interstellar medium has abundances that apparently are homogeneous to t within a factor of two, when integrated over paths of about 500 pc, and this result is i...
