Paper Title:
Biogenic Volatile Organic Compounds Emit from Ginkgo (Ginkgo biloba linn)
  Abstract

Emission rate of biogenic volatile organic compound (BVOC) released by ginkgo (Ginkgo biloba linn) was estimated from May to October 2007 in Shenyang, China. The released volatiles were collected from branches enclosed in sampling bags onto cartridges filled with Tenax-TA / Carboxen 1000 / Carbosieve SIII, and then quantified by thermal desorption gas chromatography. Isoprene was the main BVOC emitted from ginkgo in May and almost half BVOC emission was limonene during the period (from June to October). The BVOC emission rate increased from May, and reached maximum 42.21 μg g-1 dw h-1 in mid-June, then decreased quickly. Moreover, our study showed that the diurnal change of BVOC emission rate reached its maximum 32.31 µg•g-1dw•h-1 at 9:00 am, and 89.4% of the total emission was limonene. The emissions of isoprene and ocimene were correlated to both temperature (p<0.05) and light level (p<0.05).
