We study the Umov effect as applied to single irregularly shaped particles comparable with wavelength. For these particles an inverse correlation between geometric albedo and maximum of positive polarization at large phase angles does exist; however, it takes a form different from what was found for planetary regoliths. The difference is substantially caused by contribution of relatively small particles with x < 14.
