Yerevan Mayor: Concerns growing over high air pollution levels 

ArmInfo.Concerns over high air pollution levels have been growing in Yerevan in recent days. Yerevan Mayor Tigran Avinyan wrote  on his Facebook page.

According to him, the pollution is not only an issue in Yerevan, but  also in the Ararat, Armavir, and Aragatsotn provinces, as well as the  Ararat Valley districts near Yerevan. Air pollution in this region is  strictly seasonal and is primarily caused by geographical factors:  air circulation, dry anticyclonic weather, and the influx of dry,  dusty air masses, primarily from the southeast, as well as the  terrain. These natural processes are cyclical and occur annually with  varying intensity,  creating an inversion layer, virtually stopping  air exchange and leading to a constant accumulation of airborne  pollutants. 

In addition, there is an increased concentration of various gases,  organic dust, and smoke in the air due to heating, fires, and  combustion during this time of year. This further exacerbates the  situation in the absence of air exchange.

"The reduction of air pollution in the region will happen because the  inversion layer is destroyed  by the influx of cyclonic air masses  from the north. We will inform you later about the measures that the  Yerevan Municipality is taking to address this issue," the mayor  noted.
