Abstract

The cement industry has long been one of the most important environmental pollutants. For this reason, monitoring and control of environmental pollution in this industry is of particular importance. Particles in the air around cement factories are one of the most important environmental effects of this industry. In this study, after identifying the area based on topographic maps in terms of urban and rural areas and according to the data of the Meteorological Organization of Golestan Province, 20 stations were determined in different parts of the area around the cement factory. Sampling of PM2.5 and PM10 particles from stations was performed monthly from October 2020 to April 2021 by Bentek air quality meter and meteorological data were extracted from the web of the Meteorological Organization in during sampling. Then the monthly mean of particles was determined and compared with the standards of the country and zoned in Arc GIS ver10.8 software. Based on the results, the mean concentrations of PM2.5 and PM10 were about 28.98 and 70.63 µg/m3, respectively. In general, the average of most data was below the environmental standard, although in some samples the measured concentrations were above the standard due to strong winds. The study of the effect of meteorological parameters on the emission of pollution showed that temperature had the opposite effect on the concentration of particles, so that on cold and cloudy days we saw an increase in the concentration of particles.
