Particle size distribution of mineral phases and metals in dusts collected at different workplaces

摘要: Airborne dusts were collected by a two-stage sampler on an electrically activated filter at different working places. Inhalable size (particles are less than 5 μm) and course fractions separated cyclone. The particle distribution of three minerals (quartz, calcite, albite) four metals (Pb, Cd, Cr, Co) was determined. Infrared spectroscopic AAS methods applied. quartz concentrated in the while calcite inhalable ones. No direct relation to found for albite. toxic extremely enriched fine fractions, some cases 5–12 times more fractions. Since only particles might be deposited deepest parts lung importance elimination pollution sources should taken into account.
