It is shown that in a tokamak edge plasma dust particles can move with high speed and traverse distances comparable to tokamak radii. As a result, the dust deposition areas on the wall structures can be far away from the origin of the dust. Presented estimates indicate that it is very likely that transport of dust particles can be an important mechanism of core plasma contamination by impurities.
