Paper Title:
Seasonal Variations of BVOCs Emission from Ginkgo biloba Linn in Urban Area
  Abstract

In this study, seasonal biogenic volatile organic compound (BVOC) emission rates and emission patterns of Ginkgo biloba linn are estimated. The released volatiles were collected from branches onto cartridges filled with Tenax TA, and quantified by thermal desorption gas chromatography mass spectrometry (GC-MS). The result showed that the main BVOCs emitted from Ginkgo biloba linn were alkanes, aldehydes, alkenes, aromatic compounds, esters, terpenes and ketones. The total BVOC emission rate increased from May, and reached its maximum 27.96 μg C g-1dw h-1 in July, then decreased quickly. The emissions of α-pinene, isoprene, cyclohexane, methyl-cyclohexane and 2-methyl-hexane were significantly correlated to both temperature (p<0.05) and light (p<0.05).
