摘　　要：采用静态箱式采样-固体吸附-热脱附-气相色谱/质谱联用技术(TDS-GC/MS),于2011年3月到2012年12月期间对夹竹桃(Allemanda cathartica)、变叶木(Codiaeum variegatum var.pictum)、广东万年青(Aglaonema modestum)3种典型花卉的生物挥发性有机物(biogenic volatile organic compounds,BVOCs)的释放成分进行了测定研究。结果表明:3种花卉所释放的BVOCs都以烷烃、烯类、芳香烃类和酯类物质为主,含有少量的醇类、醛类、卤代烃和含氮类化合物;进入夏季后3种花卉烷烃、烯烃、芳香烃和酯类的释放都有明显的增加。3种花卉释放出的3种代表性有毒有害物质邻苯二甲酸二丁酯、乙苯和苯乙烯的释放量均为夏季最高,3种花卉有害物质释放量由高到低分别为广东万年青、变叶木和夹竹桃。研究结果对于实施对流层臭氧控制和城市绿地植物的合理选择和搭配具有重要的指导意义。Static box sampling-solid adsorption-thermal desorption-GC/MS method was adopted to measure and analyse the composition spectrum of BVOCs released by typical flowers such as Allemanda cathartica, Codiaeum variegatum vat：picture and Aglaonema modestum in Beijing during March of 2011 to December of 2012.Results showed that main types of BVOCs released by these 3 typical flowers in the study period are alkanes, arenes, alkenes and esters, and there are also little alcohols, aldehydes, halohydrocarbon and nitrogen compounds for different kinds of flowers, and quantity of BVOCs released by these 3 typical flowers in summer is much larger than that in spring and autumn. Through the quantitative analysis of three typical poisonous and harmful substances, i.e.,dibutyl phthalate, ethylbenzene and styrene released by three species flowers, it was found that the emissions of three substances are all highest in summer, with the quantity of harmful substances released in unit of time from high to low as Aglaonema modestum, Codiaeum variegatum var.pictum and Allemanda cathartica. The results would play guiding significances to implement control measures of tropospheric ozone, and provide reasonable choice and arrangement of urban green plants.
