The people's quality of life is affected by ambient air quality. In Ukraine, the confectionery enterprises are a significant emission source of organic PM
10 . The organic PM10 is a pathogen, an allergen and indirect emission source of CO2 . There is a need to determine the contribution organic PM10 from confectionery enterprise in the surface air on the outside of confectionery enterprise sanitary protection area. In this study, PM10 concentration was determined through the direct measurements method. The measurement in the winter season were performed in a residential area near the sanitary protection area of the enterprise. The mean value of PM10 at all direct measurement sites was 78.0 µg/m3 (standard deviation, SD: 6.1 µg/m3 ; 95 % confidence interval, CI: 74.2–81.8 µg/m3 ). PM10 in ground air outside the sanitary protection zone near apartment buildings in the winter period outweighs daily means limit values of PM10 for the protection of human health applied in EU by a factor of 1.6. PM10 particles by 89.8 % consist of the most environmentally dangerous particles with a size of up to 2.5 µm. Apply ionization treatment of cocoa dust emissions to increase the efficiency of collecting PM10 is proposed. [ABSTRACT FROM AUTHOR]- Published
