Scientific paper

Computations of the chemical evolution of the early-universe matter were carried out for different types of galaxies in clusters, taking account of the mass exchange between the galaxies and intergalactic medium (IGM). It is concluded that the chemical enrichment of the IGM by the elements synthesized in stars was produced as a consequence of mass ejection from galaxies. The contribution to this enrichment depends more on the mass of the galaxy rather than on its type. Both spiral and elliptical galaxies of a cluster lead to an approximately identical enrichment of IGM by heavy elements.
