Fog Leaves Air in Bulgarian Capital Heavily Polluted
The lingering fog has caused air pollution in Bulgarian capital Sofia to soar to over 4 times the norm, according to the Bulgarian Excutive Environment Agency.
The concentration of fine dust particles is 4-8 times over the norm at different localities, with the Hipodruma, Pavlovo, Orlov Most, Nadezha and Druzhba neighborhoods the most polluted.
In early December, there was excessive pollution in Bulgaria only in the cities of Blagoevgrad, Pernik and Shumen.
Last Friday, when fogs fell over large parts of the country, excessive pollution was recorded in 18 cities.
