摘　　要：非甲烷总烃(NMHC)指的是除甲烷以外的所有可挥发的碳氢化合物的总称。由于其存在挥发性,常易存在于空气中。若空气中的NMHC超过一定浓度,会对接触该空气人们的身体健康造成危害,且在一定条件的太阳照射下,NMHC能与氮氧化合物、光氧化剂发生反应,产生浅蓝色的光化学烟雾污染。光化学烟雾污染不仅会危害人体健康,损害植物、动物、农作物等生命体,还会降低区域环境的可见度,从而对人们生活工作造成诸多的不良影响。基于此,b本文对城市空气中NMHC含量和排放源进行了调查研究,掌握了城市NMHC的污染状况、主要污染来源、污染途径、污染浓度范围及变化规律,最后提出了几点防治技术。Non-methane hydrocarbons(NMHCs) encompass all volatile hydrocarbons except methane.Their volatility ensures their ubiquitous presence in the atmosphere.Concentrations of NMHCs in the air that surpass certain thresholds can pose health hazards to humans.Under conditions of solar irradiation,NMHCs can react with nitrogen oxides and photooxidants,thereby resulting in the formation of light blue photochemical smog.This smog not only endangers human health and damages plants,animals,and crops but also reduces visibility in affected areas,adversely impacting daily life and work.Based on this,this study conducted a thorough investigation into the concentration and emission sources of NMHCs in urban air,seeking to comprehend the pollution status,primary sources,pathways,concentration ranges,and fluctuation patterns.Consequently,several preventive and control technologies were proposed.
