Tests have been carried out for the first time on the hypothesis that the structure of interstellar dust around galactic bars is determined by the velocity field of the gas. The dust is found in regions delineated by high gas speed gradients, something which had been proposed but not observed. The gradients themselves seem to be related to intense star-forming regions.
