摘要

为了解农作物挥发性有机化合物(VOCs)排放特征及其大气反应活性,选取典型农作物小麦(Triticum aestivum)、玉米(Zea mays)、大豆(Glycine max)、花生(Arachis hypogaea),应用动态封闭式采样法、热脱附-气相色谱质谱联用(TD-GC-MS)技术对其VOCs排放进行野外观测和定量分析,研究4种农作物的VOCs排放速率和化学组成特征,计算它们的羟基自由基消耗速率(L_OH)和臭氧生成潜势(OFP).结果表明,4种农作物总VOCs排放速率排序为花生((43.27± 18.8) μg/(g·h))>小麦((21.63 ± 8.24) μg/(g·h))>大豆((2.97 ± 0.67) μg/(g·h))>玉米((0.36 ± 0.15) μg/(g·h)),各农作物的主要排放贡献组分包括异戊二烯、正庚烷、环戊烷、对-二甲苯、间-二甲苯等;各农作物排放的VOCs中检出的化合物种类及其排放组成不同,其中小麦主要排放烷烃和芳香烃,玉米主要排放单萜烯,大豆主要排放烷烃,花生主要排放异戊二烯,仅在大豆排放的VOCs中检测到烯烃.不同农作物排放VOCs的L_OH和OFP的排序均为花生>小麦>大豆>玉米,异戊二烯、柠檬烯、反式-β-罗勒烯、β-石竹烯和环戊烷是4种农作物排放的关键VOCs活性组分.

Abstract

Dominated crops Triticum aestivum, Zea mays, Glycine max, and Arachis hypogaea were selected to study the Volatile Organic Compounds (VOCs) emission characteristics and their atmospheric reactivity of crop. The dynamic enclosure system and the thermal desorption and gas chromatography-mass spectrometry (TD-GC-MS) technique were used for the quantitative analysis of VOCs emission. The VOCs emission rate and chemical composition characteristics of four crops were studied, and their hydroxyl radical consumption rate (L_OH) and O₃ formation potential (OFP) were calculated. The results showed that the total VOCs emission rates of four crops were ranked as Arachis hypogaea ((43.27 ± 18.8) μg/(g·h)) > Triticum aestivum ((21.63 ± 8.24) μg/(g·h)) > Glycine max ((2.97 ± 0.67) μg/(g·h)) > Zea mays ((0.36 ± 0.15) μg/(g·h)). The major emission contributing components of each crop included isoprene, n-heptane, cyclopentane, p-xylene, and m-xylene. The composition of VOCs emitted by the four crops were different. Triticum aestivum mainly emitted alkanes and aromatics, Zea mays mainly emitted monoterpenes, Glycine max mainly emitted alkanes, and Arachis hypogaea mainly emitted isoprene. Alkenes were detected only in VOCs emitted from Glycine max. The L_OH and OFP of VOCs emitted by different crops also followed the same ranking: Arachis hypogaea > Triticum aestivum > Glycine max > Zea mays. Isoprene, limonene, trans-β-ocimene, β-caryophyllene, and cyclopentane were the key active components of VOCs emitted by the four crops.
