Short summary
A long-term estimation of the chemical composition of PM2.5, a chemical mass closure exercise, and the source identification of particulate matter took place at an urban background site of central Athens, allowing us to further assess the impact of residential heating as a source of air pollution over Athens. PM2.5, EC, POM, NO3-, C2O42-, nssK+, Pb, and Cd were increased by up to a factor of 4 at night compared to during the day, highlighting the importance of heating on air quality in Athens.
