title: [Composition of the dust for the assessment of the exposure to the population in the areas of influence of industrial emissions of stationary sources].
abstract: The results of instrumental studies of the dispersion and component composition of the solid component of the dust gaseous emissions from industrial stationary sources of engineering and metallurgical enterprises are presented. Dust and gas mixtures were established to contain up to 80% fractions with a particle size less than 10 microns (PM10), and 40% of fractions with size smaller than 2.5 microns (PM2.5). In the composition of the dusts particles in the nano-sized range have been identified. The main chemical components of dusts are iron, silicon, aluminum and their oxides, but in the set of dusts manganese, chromium, vanadium, and other toxic metals account for 25% of the weight. Accounting disperse composition of dusts in the evaluation of pollution allows to establish the zone of influence of sources more accurately, correctly assess the exposure to the population with bearing in mind the such hygienic criteria as PM10 and PM2.5 sampling.
