Abstract—The study and analysis of dust nano- and microparticles are necessary in the estimation of anthropogenic load on the environment and the determination of the sources of pollution in urban ecosystems. In this work, an approach based on a multistage membrane filtration method is proposed for assessing the contribution of a metallurgical enterprise to the pollution of nano- and microparticles in urban dust. The contribution of an aluminum smelter to dust pollution in Kandalaksha was estimated. The elemental composition of the initial dust samples was studied. The fractions of dust particles with sizes of
