Determination of the sources and the composition of suspended microparticles in the atmosphere that affect the climate of Greece
In order to monitor winter air pollution levels and study the contribution of different sources to them, detailed measurements of the concentration and composition of suspended particles in the five largest Greek cities (Athens, Thessaloniki, Patras, Heraklion and Ioannina) were carried out between 10 January and 10 February 2013. The experiment was carried out in the framework of the ESPA-THALIS project with the theme “Determination of the Sources and the Physicochemical Properties of Fine and Ultrafine Particulate Matter (Aerosol) that affect the Climate of Greece”.
In conclusion, based on their size and chemical composition, particles produced by wood burning appear to be as dangerous to human health as particles from vehicular traffic and other combustion sources. Our measurements demonstrate the magnitude of the air pollution problem that can be created both in Athens and in other Greek cities, if the burning of wood is combined with the appropriate weather conditions (low temperatures and apnea). Fortunately, these conditions have been relatively rare this winter. This does not mean that we should repeat as a country this “experiment” of high emissions in the coming years and hope that nature will show understanding.
