Impact assessment of PM10 from the confectionary enterprise on urban air quality.

The people's quality of life is affected by ambient air quality. In Ukraine, the confectionery enterprises are a significant emission source of organic PM₁₀. 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]
