Abstract

Air pollution in urban cities is a serious problem. This happens as a result of weak cooperation between central and local institutions. This problem is more present in some cities in the Republic of North Macedonia. With the start of the heating season in winter, like every other season, air pollution is undoubtedly updated. Due to the large use of fuels, solid and liquid, there is a lot of pollution in some larger cities in our country. The paper collects some data from measuring stations in several cities that have caused and presented greater pollution and risk. The data were collected every day in the period from January 30, 2019 to February 04, 2019, at different times of the day such as in the morning: at 8.00 and 9.30, and in the evening at 18.00, and 19.30. In addition to PM particles (Pm10 and Pm2.5), data have also been collected for some gases such as: CO, SO2, and NO2, as well as the percentage of AQI (Air quality index), Exceeding the average value is calculated if it exceeds 50 micrograms per cubic meter. We have more numerous and more drastic exceedances in the cities of Tetovo and Skopje, where in some cases the value has been exceeded several times. Several factors are considered as causes of pollution.
