  1. Reaktionsmechanismen der Ozongenerierung in der unteren Troposphäre R – CH3 + ·OH  R - ·CH2 + H2O R – ·CH2 + O2  R – CH2O2· R – CH2O2· + NO  R – CH2O· + NO2 R – CH2O· + O2  R – CHO + HO2· NO + HO2· NO2 + ·OH 2 NO2 2 NO + 2 O 2 O + 2 O2  2 O3   Gesamtgleichung: R – CH3 + 4 O2 R – CHO + 2 O3 + H2O

  2. Entstehung ohne Kohlenwasserstoffe Photolyse bei UV-Einwirkung: λ = 400 nm 2 NO2 + 2 O2 2 NO + 2 O3 2 NO + O2  2 NO2 Bildung aus Schwefeldioxid SO2 + O2 + NO  SO3 + NO2 NO2 + O2  NO + O3
