Study of the effect of biogenic VOC emissions on regional ozone production and the implications for VOC or NO{sub x} control
- Fraunhofer Inst. for Atmospheric Environmental Research, Garmisch-Partenkirchen (Germany)
A key question for the development of air pollution control strategies is whether to reduce nitrogen oxides (NO{sub x}) or volatile organic compound (VOC) emissions. Significant levels of biogenic VOC emissions may greatly limit the effectiveness of VOC control strategies. Concerns have been raised because for many cities it has been suggested that biogenic emissions are a dominate source of VOCs. Biogenic emissions would be expected to contribute an even larger fraction of the VOC emissions on the regional scale than within urban areas. The authors used a new atmospheric chemistry mechanism, the Regional Atmospheric Chemistry Mechanism (RACM), to perform ozone reactivity calculations to investigate the effects of biogenic emissions on the production of photooxidants in the atmosphere. The results show that incremental reactivity of isoprene is about the same as xylene and that the incremental reactivities of d-limonene and a-pinene are near those of toluene.
