Research of air pollution by fine suspended particular mater in the city of Zaporozhye

Abstract

The aim of the work is a hygienic estimation of the air pollution condition by fine suspended particular mater (PM10 and PM4) in the city of Zaporozhye. Materials and methods. The measurements of fine suspended particular mater PM10 and PM4 have been carried out since 2012 to 2017 years in the atmospheric air of Zaporozhye. It was used the KANOMAX-3521 aerosol analyzer for measurements. The data processing was performed with the statistical package of the licensed program “STATISTICA® for Windows 13.0” (StatSoft Inc., No. JPZ8041382130FRCN10-J) and the “Microsoft Excel” program. Results. It has been established that PM10 concentrations in the air of Zaporozhye exceed the recommended levels by the WHO guidelines for air quality. The average concentrations of РМ10 in the city - 0.14 ± 0.002 mg / m3, РМ4 - 0.07 ± 0.001 mg / m3, the concentration of РМ10 is 1.2 times higher (p<0.05) in the Voznesenovsky district. In the experimental areas, the concentration of PM10 is 1.08-1.9 times significantly higher (p <0.001) than in the control area. Maximal index of concentration was recorded in August (seasonality coefficient 1.8-1.83). It was established a strong inverse correlation between the relative humidity of the air and the concentration of PM10 (r = – 0.85) and PM4 (r = – 0.83) and the statistically significant difference between the concentrations of these substances in the evening and in the morning hours of the day (p <0.001). The results of the research indicate the necessity to organize the continuous monitoring of the fine suspended particular mater content in the air and the creation of a hygienic regulatory document for the PM.
