The main purpose of this work was to measure the ambient levels of PM10 particulate matter and their concentrations of metals and ions in 9 different size bins. The mean PM10 concentration during the first measurement period was equal to 28.3 ± 12.4 μg/m3 , whereas during the period of July 2008 was 41.6 ± 14.0 μg/m3 . Moreover, mean concentrations of PM3.3 particulate matter were measured on the average equal to a 49 % and 45 % of PM10, respectively. The measurements showed high concentration of nanoparticles (with aerodynamic diameter less than 0.9 μm), whereas the mass concentration peak was located at an aerodynamic diameter of 4 - 5 μm. Back trajectory analysis showed that during the measurement period winds were mainly originated from North-West direction. http://creativecommons.org/licenses/by/4.0/ 11th International Conference on Environmental Science and Technology Lazaridis Michalis Λαζαριδης Μιχαλης Mihalopoulos, Nikolaos Zarmpas,P Pentari,D Kopanakis,I Katsivela,E Air--Pollution--Control Air pollution control Air quality--Management Control of air pollution air quality management air pollution control control of air pollution
