Abstract: The low metal content of dwarf galaxies and the metal enrichment of the intergalactic medium both suggest that mass loss triggered by star formation activity has to play a major role in the evolution of galaxies, especially of dwarf galaxies. These galaxies provide a perfect environment to study feedback processes as they show strong starburst activity, but are simple systems, which makes the interaction between stars and the interstellar medium very efficient. However, no clear evidence for mass loss in local dwarf galaxies has been found, yet. Therefore, we perform a detailed kinematic analysis of two nearby irregular dwarf galaxies, NGC 2366 and NGC 4861, in order to search for expanding gas and to get an idea what its fate is.
