Bulgaria capitals

On New Year’s Eve, the air in Bulgaria was 2-3 times more polluted than normal – Novinite.com

The concentration of fine dust particles (FDP10) in the air in large cities was 2 to 3 times higher in New Yearcompared to the evening hours of December 31, 2021 and the morning of January 1, 2022.

This is shown by the analysis of the Ministry of Environment and Water based on data from the Environmental Executive Agency (EEA) stations in the country.

According to the findings of the agency’s experts in 3 of the 5 stations in the capital, the concentration of FDP10 increases even more than 3 times after midnight. Measurements at the Pavlovo station show that the fireworks effect peaks at 236.44 µg / m3 (micrograms per cubic meter) at 3 p.m., then gradually weakens and only reaches at 9 o’clock lower concentrations of 70.17 mg / cubic. mr. By way of comparison, data from 6 p.m. on December 31 shows only 7.92 µg / m3.

Measurements at the Mladost checkpoint show that if at 6 p.m. on December 31 the concentration of FDP10 was 18.68 µg / m3, then at 2 a.m. on January 1 it reached 69.02 µg / m3. The increase in staff at Nadezhda station is drastic – from 23.33 at 6 p.m. to 170.52 µg / m3 at 1 p.m.

For comparison, on December 29 the concentration in individual points at the hours around midnight ranges from 40 to 100 µg / m3, and on December 30 it is only 5-6 µg / m3.

According to the normative requirements, the average daily standard for FDP10 is 50 µg / m3.

In many other large cities in the country, there is a significant increase in the concentration of fine dust particles. At one of the Plovdiv stations at 16.61 µg / m3 at 6 p.m., they amount to 31.81 µg / m3. In the same time zones follow the data for the cities: Varna – from 20.43 to 42.88 µg / m3; Vidin – from 6.80 to 30.85; Dobrich – from 14.99 to 35.08; Blagoevgrad – from 19.37 to 174.70; Kardjali – from 43.88 to 146.44; Pernik – from 4.10 to 66.13; Bourgas – from 46.66 to 127.47 µg / m3.
