Abstract: SO2, NO2 and particulate matter (PM) are air pollutants, generated by a variety of human activities and can travel long distances in the atmosphere and cause a wide range of air quality problems in Europe. For some cities, the influence of transboundary and national contributions in PM concentrations is dominant, and only a little improvement can be expected from local control policies. The air quality of Budapest is determined mainly by the local residential heating and traffic emissions combined with the meteorological conditions. Sometimes the impact of the transboundary sources can be negligible especially under special meteorological conditions when the local effects determine the air quality of Budapest, but sometimes it could be responsible for the formation of air pollution episodes. In this research, the effect of long-range transport on the air quality of Budapest was analysed in details, using the outputs of EMEP chemical transport model.
Keywords: long-range transport; EMEP chemical transport model; urban air quality; emission.
