Abstract

We observed the rest frame ultraviolet for 70 high redshift quasars (z ≥ 3:5). The fluxes of several ultraviolet emission lines were used to estimate the chemical composition of the line emitting gas and date the first star formation epoch. The line ratios were analysed within the frame work of the most recent photoionization models. We estimated an average abundance of Z=Z.
