We compare the metallicities in high-redshift quasars to the star formationrates (SFR) in their host galaxies using measurements of broad emission linesand far-infrared (FIR) luminosities. The FIR emission indicates the level ofongoing massive starbursts in the galaxy, whereas the abundance of metals inthe gas surrounding the quasar indicates the amount of star formation whichoccurred before the visible quasar phase began. The results of this study canbe used to constrain the late stages of starburst-quasar evolution. We detecthigh metallicities throughout the sample, up to several times solar, confirmingthat star formation must have begun before the visible quasar phase. However,we do not detect a trend in metallicity versus current SFR.
