Atmospheric Chemistry of volatile and semi-volatile organic compounds
Aromatics are a major contributor to the formation of regional ozone in urbanized areas. Toluene, for example, is ranked fourth of all volatile organic compounds in terms of overall contribution to ozone production in northern Europe, behind butane, ethane and ethanol, based on a recent trajectory model calculation by Derwent et al. (2003). The calculations also demonstrate that episodic peak ozone concentrations are decreasing in Europe, primarily because of motor vehicle emission controls brought in during the 1990s. However, there is a clear and continuing increase in background ozone concentration that derives from anthropogenic effects on hemispheric atmospheric chemistry.
