A recent XMM-Newton observation of BALQSO PG1115+080(z1.72) has detected strong absorption lines in the Fe line region. A comparison between this and an earlier Chandra observation of PG1115+080 separated by 19~weeks resulted in a weak constraint on the variability of these absorption lines due to the low S/N of the Chandra spectrum.The proposed XMM-Newton observations will allow us to (a) monitor the variability of the Fe lines,(b) test the correctness of the present interpretation of these lines,and (c) constrain the kinematic,ionization and absorbing properties of the quasar outflow.These constraints will allow us to determine the contribution of outflows to the enrichment of the IGM,and provide insights of the connection between black hole and bulge growth in the host galaxy.
