Atmospheric air pollution is one of the major environmental challenges facing humanity today. Atmospheric air is polluted with harmful substances emitted from anthropogenic and natural sources.
The main sources of air pollution are: transport, energy, industry and agriculture.
According to the World Health Organization (WHO), 91% of the world's population lives in an environment where air quality does not meet (WHO) standards.
The problem of air pollution in Georgia is observed in the largest cities of the country, as well as in large industrial facilities or industrial zones. Atmospheric air quality in Georgia is monitored by the National Environment Agency of the Ministry of Environment Protection and Agriculture. In 2014-2017, the outdated air quality assessment system was gradually replaced by modern European systems. There are 8 new, state-of-the-art automatic stations in the country, which enable 24-hour monitoring of ambient air quality. Also, the National Environment Agency has been conducting indicator measurements since 2015 in order to strengthen the monitoring of air pollution, within which the content of nitrogen dioxide, ozone and benzene in the air will be determined in 25 cities of Georgia. Results from automated air quality monitoring stations show that particulate matter (PM10, PM2.5¬) and nitrogen dioxide are problematic pollutants in the country's major cities.
