BIOGENIC VOCS EMISSIONS AND ITS IMPACT ON OZONE FORMATION IN MAJOR CITIES OF CHINA

摘要

A measurement campaign was performed in two large cities in China,Beijing and Guangzhou, to investigate biogenic emissions of volatileorganic compounds (VOCs)using a GC-FID system and the enclosurechamber technique. Four typical types of trees, namely pine, cypress,poplar and Chinese-scholar tree were studied. The influences oftemperature and light intensity of VOC emissions were analyzed Usingalgorithms derived from what is currently understood about VOCemission Mechanisms.
