In our study we are searching for gas accretion onto void galaxies. The void environment is favorable for searching for distinguishing between different sources of accreted gas. The accretion events could lead to drop of metallicity in certain regions, kinematical perturbations and star formation on the periphery of galaxies. So for such study the data on ionised gas kinematics of starforming regions could be used. We compiled a sample of void galaxies with intermediate luminosities that reveals unusual and perturbed appearance, and have relatively low metallicity for their luminosity in comparison with standard relation. To examine the hypothesis of accretion onto these galaxies we use Fabry-Perot interferometer data in Hα line. In most of sample objects including two isolated galaxies without any known companions we indeed observe non-circular motions that might be caused by accretion of external gas or by tidal disturbance.
