title: [Evaluating exposure of population to dust, with consideration of components and dispersion contents of industrial discharges from enterprise extracting and processing mineral raw materials (discussion)].
abstract: The article covers results of study concerning disperse content of solid components of discharges from main dust- generating technologic operations in extraction and processing of mineral raw materials (pouring ore to conveyor, drying with combustion gas in fluid-bed, pouring of end product, sorting ore on riddle, drying on vibration dry and cool device, etc). Findings are that fractions under 10 and 2.5 micrometers approach 50% in general structure of dust discharges. Maximal share of low-disperse dust enters ambient air from vibraion dry and cool devices, riddles and pouring places. Exceeded reference values for acute and chronic exposure are registered on TSP and PM10 at a sanitary protection zone border and in the nearest living area points--that can forecast intolerable risks for health of population exposed and necessitate instrumental confirmation of the detected jeopardy level.
