A new estimate of the interstellar ultraviolet radiation field is used to analyse some well established observations of interstellar Na i, Ca n, Mg i, n in £, e and 8 Ori. Four models of the interstellar medium are used and chemical abundances derived relative to that of hydrogen, obtained from Lyman a data. The scatter of the results is discussed together with the apparent anomalous abundance of calcium.
