A standard procedure for the determination of plutonium in soil was modified and applied for the assay of this element in dust and aerosols collected from ground-level air on a Petrianov filter, in an ASS-500 air monitoring station. The modification consists in replacing a dry ashing mineralization step by direct acid leaching. The problem of polonium interference with plutonium determination was also discussed and the concentration of polonium in air was estimated.
