The team is taking regular air samples at three locations in Greece – Crete, Athens and Patras. ![]() ![]() Globally, wildfire smoke is estimated to cause over 339,000 premature deaths a year – far more than those who lose their lives directly in these blazes. Nenes is principal investigator of the PyroTRACH project, which is attempting to find out how emissions from wildfires – along with other types of biomass burning, such as domestic wood fires – change in the atmosphere and the impact this has on human health and climate. They are affecting air quality over entire regions or parts of continents.’ ‘In the eastern Mediterranean we get smoke that blows down from forest fires in Russia and when it happens there is just hazy smoke everywhere,’ said Professor Athanasios Nenes, an atmospheric chemist at the Institute of Chemical Engineering Sciences in Patras, Greece. With large fires, the smoke can rise many kilometres into the stratosphere and spread across entire regions, causing air pollution in areas far away from where the flames actually were. Blazes in the Arctic in June set a new record in carbon emissions in 18 years of monitoring.Īs the trees, shrubs, grass and peat are engulfed by these fires, huge quantities of smoke, soot and other pollutants are released into the air. In 2018, more than 204,861 hectares of land were left burnt in Europe and other countries around the Mediterranean, while the previous year wildfires destroyed over 1.2 million hectares. ![]() Every year, thousands of fires engulf forests, grasslands and moors across Europe. ![]()
