<p>To provide a composition for dust-preventive treatment comprising aqueous dispersion of fluorine-containing polymer showing a low potential for environmental concerns and a dust prevention effect as high as that of known composition for dust-preventive treatment. To provide a composition for dust-preventive treatment comprising aqueous dispersion of fluorine-containing polymer containing 50 ppm or less of a fluorine-containing emulsifier. The composition for dust-preventive treatment comprising aqueous dispersion of fluorine-containing polymer containing 50 ppm or less of a fluorine-containing emulsifier obtained by removing the fluorine-containing emulsifier from polymer dispersion prepared by polymerizing tetrafluoroethylene using the fluorine-containing emulsifier is a preferable embodiment of the present invention.</p>
