Average concentration of dust in Yerevan in June of this year exceeded the maximum permissible concentration (MPC) of 3.1 times, said on Wednesday the news site News.am referring to the Ministry of Environment of Armenia.
In addition, the concentration of nitrogen dioxide in the Armenian capital exceeded the norm by 2.6 times, nitrogen monoxide and sulfur dioxide are within acceptable limits.
For comparison, the average concentration of dust in the second largest city of the Republic of Gyumri in June exceeded MPC by 1.9 times (compared to May concentration increased 1.4 times).
In other cities, the concentration of dust is not tracked — only in Ararat and Hrazdan measured density of cement dust. In both cities, it is more than the rate of about 1.2 times. This situation is explained by the fact that these cities are in the country's largest cement plants.
