摘要
The air quality index LAQx (Long-term Air Quality Index), which has been recently developed to evaluate the long-term integral air quality related to well-being and health of people, was applied to analyse the evolution of air pollution from 1985 to 2005 at different urban and rural sites in SW Germany. The LAQx method including the air pollutants taken into account is briefly discussed. LAQx is grouped into six classes according to the German school grade system, i.e. LAQx class 1 indicates a very good air quality, while very poor air quality is described by LAQx class 6. For an additional differentiation, the six LAQx classes are subdivided into LAQx values based on the decimal system.
