摘要：

SO2 is no longer the principal factor influencing the vitality and composition of lichen assemblages in London. We provide direct evidence for an impact on lichen growth during episodic high exhaust emissions coupled with unusual climatic conditions. This suggests a combination of particles and nitrogen plays a major role in influencing lichen growth. Nitrogen from traffic emissions may be at least as important as agriculture in influencing the composition of lichen assemblages. (C) 2002 Elsevier Science B.V. All rights reserved.
