Abstract: | There are many processes that can transport gas from the galaxies to their environment and enrich the environment in this
way with metals. These metal enrichment processes have a large influence on the evolution of both the galaxies and their environment.
Various processes can contribute to the gas transfer: ram-pressure stripping, galactic winds, AGN outflows, galaxy-galaxy
interactions and others. We review their observational evidence, corresponding simulations, their efficiencies, and their
time scales as far as they are known to date. It seems that all processes can contribute to the enrichment. There is not a
single process that always dominates the enrichment, because the efficiencies of the processes vary strongly with galaxy and
environmental properties. |
