Urban areas are major sources of air pollution. Pollutant emissions affecting air quality in cities are considered to have adverse consequences for human health. Public and government concern about environmental issues arising from urban air pollution has increased over the last decades. The urban air pollution problem is widespread throughout the world and it is important to find ways of eliminating or at least reducing the risks for human health. The fundamentals of the physical and chemical processes occurring during air pollutant transport in the atmosphere are nowadays understood to a...

Hohe bodennahe Ozonkonzentrationen sind ein Hinweis auf den sogenannten photochemischen Smog, der bei h-herer Emission von Stickstoffoxiden, Kohlenmonoxid und Kohlenwasserstoffen und starker Sonneneinstrahlung auftritt. Diese Art der Luft- verschmutzung kommt auch in unseren Breiten vor, in erster Linie im Sommerhalbjahr. Zu den Folgen z{hlen Waldsch{den, gesundheitliche Belastungen f}r Mensch und Tier und die Zer- st-rung historischer Kunstwerke. Durch Emittierung aller an der Smogbildung beteiligten Schadstoffe tragen Kraftfahrzeu- ge erheblich zur Entstehung photochemischen Smogs bei. Das...
