The amount of fine dust particles in the air of 15 Bulgarian cities is higher than permissible.
In four of them – Varna, Pernik, Pleven and Lovech, the air pollution is nearly twice as high as the allowed levels.
The air in Sofia, Plovdiv, Burgas, Blagoevgrad, Smolyan, Kurdzhali, Dimitrovgrad, Nesebar, Gorna Oriahovitsa, Vratsa and Vidin also contains excessive amounts of fine dust particles. In certain areas of Sofia the levels were three times higher than the norm, NovaTV reported.
According to Valeri Serafimov of the air monitoring department of the Environmental Agency, increased air pollution is allowed for up to 35 days per year, but more than that may be dangerous.
Recently Greenpeace published a report, which claimed that Bulgaria has the highest air pollution with sulfur dioxide and fine dust particles per produced kWh of electricity in Europe.
