We compiled a sample of void galaxies with intermediate luminosities that reveals unusual and perturbed appearance. Some of them have relatively low metallicity for their luminosity in comparison with standard relation. Our hypothesis is that such propertie might be caused by the accretion of the external gas onto these galaxies. To examine this hypothesis we use FabryPerot interferometer data in Hα line. In most of sample objects including two isolated galaxies without any known companions we indeed observe noncircular motions that might be caused by accretion of external gas or by tidal disturbance.
