摘要:
为揭示枫香树Liquidambar formosana 释放挥发性有机化合物(VOCs)的种类、VOCs 的抑菌效果及净化空 气作用,本研究采用热脱附-气相色谱-质谱(TDS-GC-MS)联用技术,分析鉴定了枫香树单株和枫香树林的VOCs 组分及含量,同时测定了枫香树林在春季、夏季和秋季的空气负离子浓度和空气微生物(细菌、真菌、放线菌) 分布状况。结果表明,单株枫香树释放的VOCs 共鉴定出3 类26 种化合物,主要成分有柠檬烯、月桂烯、β-蒎 烯等,其中萜烯类占VOCs 总量的96.6%。春、夏、秋季枫香树林空气中的VOCs 共有7 类28 种化合物,主要以 萜烯类、苯类物质为主,其中,春季共有5 类21 种化合物,主要有柠檬烯、β-蒎烯、甲苯等;夏季共有5 类21 种化合物,主要有柠檬烯、β-蒎烯、甲苯等;秋季共有4 类6 种化合物,主要有甲苯、邻二甲苯、十六烷酸等, 不同季节VOCs 的种类与含量存在差异,夏季总释放量分别是春、秋季的1.2、69.5 倍,春季和夏季主要成分有柠 檬烯、β-蒎烯、月桂烯等,其中萜烯类分别占VOCs 总量的28.4%、40.5%。春季、夏和秋季空气负离子浓度与 对照(空地)比分别增加了61.8%、68.7%、29.5%。春季、夏季和秋季枫香林内细菌含量与对照比分别降低了27.9%、 49.5%、18.9%;春季和夏季真菌含量与对照比分别降低了21.4%、38.3%。利用VOCs 单体抑菌试验表明,β-蒎 烯、柠檬烯、月桂烯、γ-萜品烯对细菌抑制效果显著,后3 种也对真菌抑制作用显著。综上所述,枫香树林释放 的VOCs 具有抑制空气微生物生长、净化空气的作用。
Abstract:
To reveal the species of volatile organic compounds (VOCs) released by Liquidambar formosana, the bacteriostatic effect of VOCs and the purifying effect of air, the composition and content of single Liquidambar formosana and Liquidambar formosana forest were analyzed and identified by thermal desorption gas chromatography-mass spectrometry (TDS-GC-MS),The results showed that there were 26 kinds of 3 types compounds from VOCs of single tree, mainly limonene, myrcene, β-pinene, etc., terpenes accounted for 96.0% of the total VOCs. There were 28 kinds of 7 types compounds from VOCs in the stand, including terpenes and benzene, among them, there were 21 kinds of 5 types of VOCs in spring and summer, 6 kinds of 4 types in autumn. Kinds and content of VOCs differed with seasons, total release in summer was 1.2 and 69.5 time of that in spring and autumn. The negative air ion concentration in stand in spring, summer and autumn increased by 61.8%, 68.7% and 29.5% compared with that in the control (open space). Compared with the control, in spring, summer and autumn, the bacterial content decreased by 27.9%, 49.5% and 18.9%, while in spring and summer, the fungal content decreased by 21.4% and 38.3% respectively.
