Significant atmospheric pollution levels were recorded across Greece in recent days, according to data from the PANACEA platform (Air of the National Observatory of Athens.

The platform analyzes atmospheric composition and, as indicated by its data, extremely high concentrations of airborne fine particles PM 2.5 were observed nationwide due to increased fireplace emissions and specific meteorological conditions such as stagnant air, humidity, and lack of rain. In some cases, these concentrations exceeded normal levels by up to 20 times.

Ioannina appeared to be the most heavily affected region in the country. Consequently, in almost all mainland Greece areas, measurements showed a substantial atmospheric burden, except for Crete, where air quality remained better. Elevated concentrations of fine particles were recorded in the Peloponnese, including Corinth, Nafplio, Athens, and Thessaloniki.

However, by Friday, the situation had significantly improved in the capital and the Peloponnese. The atmosphere remained heavily burdened in the Thessaloniki area and even more so in Ioannina.
