Characteristics and chemical reactivity of biogenic volatile organic compounds from dominant forest species in the Jing-Jin-Ji area, China

Abstract Background Biogenic volatile organic compounds (BVOCs) play an essential role in tropospheric atmospheric chemical reactions. There are few studies conducted on BVOCs emission of dominant forest species the Jing-Jin-Ji area China. Based field survey, resources data and measured standard factors, Guenther model developed 1993 (G93) was applied this paper to estimate from several ( Platycladus orientalis , Quercus variabilis Betula platyphylla Populus tomentosa Pinus tabuliformis Robinia pseudoacacia Ulmus pumila Salix babylonica Larix gmelinii ) 2017. Then spatiotemporal characteristics reactivity these were extensively evaluated. Results The results showed that total annual estimated be 70.8 Gg C·year ? 1 consisting 40.5 % (28.7 isoprene, 36.0 (25.5 monoterpenes 23.4 (16.6 other VOCs. emissions tabulaeformis contributed 56.1 %, 41.2 31.1 respectively. accounted for 61.9 1.8 summer winter, Up 28.8 detected Chengde followed by Beijing with 24.9 mainly distributed Taihang Mountains Yanshan Mountains. Additionally, reaction activity. Conclusions peaked (June, July, August) bottomed out winter (December, January, February). most, Beijing. represent primary contributors reactivity, hence planting should reduced.
