The investigations of the atmospheric dusts in the Głogów-Żukowice area detected the presence of unaltered grains and fragments of ore minerals characteristic of the ore from the Legnica Głogów Copper District. Industry in the Żukowice area emits not only sulphides and arsenides of such metals as Cu, Pb, Zn, and Ni but also alloys of Pb and Pb-Cu as well as precious metals. Size of the dust particles varies considerably from submicroscopic grains to several hundreds of micrometers. The particles are usually xenomorphic grains or crystals and ore fragments (mainly shale ore). Intergrowths of ore minerals are rare. The biggest grains consist of semigraphite blades and unaltered fragments of bituminous shale. Bornite, chalcopyrite, goethite, chalcocite, hematite, covellite, marcasite, arsenides of Ni-Co (rammelsbergite-safflorite), fragments of Bessemer and shaft furnace slag, metallic silver and copper, metallic iron, ilmenite, magnetite, malachite, cuprite, pyrrhotite, metallic lead and lead alloys were detected in the polished samples.
