Hygienic assessment of PM10 and PM2.5 contents in the atmosphere and population health risk in zones infleunced by emissions from stationary sources located at industrial enterprises

Our research focused on air contamination with solid particles which occurred in settlements influenced by stationary sources located at enterprises involved in construction materials production. Our goal was to examine concentrations and fractional structure of solid particles and to assess health risks caused by air contamination with fine-dispersed solid particles for population living on territories adjoining to sanitary-hygienic zones of industrial enterprises. The research was conducted with laboratory control techniques, health risk assessment, sanitary-hygienic and statistic techniques. We measured solid particles concentrations in real-time detecting them incessantly, and it allowed us to obtain data on concentrations of fine-dispersed solid particles (10 and 2.5 microns diameter) averaged over 20-minutes period; we also managed to calculate sums of solid particles (dust/aerosol not differentiated in its compound) in the atmosphere in settlements influenced by stationary sources located at industrial enterprises. We analyzed fractional structure of solid particles, performed a hygienic assessment of atmospheric air contamination, and determined population health risks caused by atmospheric air contamination with fine-dispersed particles. The obtained results gave grounds for working out analytical (laboratory) techniques for control over atmospheric air contamination at a border between a residential area and a sanitary-hygienic zone and for hygienic assessment of solid particles content in the air in settlements, both for overall fraction and for particles with aerodynamic diameter 10 microns and 2.5 microns.
