  The main goal of the present work is to estimate the effects of plasma
environment on the atomic parameters associated with the K-vacancy states in
highly charged iron ions within the astrophysical context of accretion disks
around black holes. In order to do this, multiconfiguration Dirac-Fock
computations have been carried out by considering a time averaged
Debye-H\"uckel potential for both the electron-nucleus and electron-electron
interactions. In the present paper, a first sample of results related to the
ionization potentials, the K-thresholds, the transition energies and the
radiative emission rates is reported for the ions Fe 23+ and Fe 24+ .
