A collapse of perturbation of the impurities (Li, С, O, Si, Ti, stainless steel, Cu, Mo, W), which was introduced into the central region of the plasma by a macroparticle, is investigated. It is shown that the impurities are extracted from the discharge with a characteristic time r that depends weakly on their type. The values of r are determined according to the prediction of the theory which takes into account the poloidal rotation of the plasma.
