摘　　要：挥发性有机物(VOCs)来源广泛,组成复杂,且与低空大气层中臭氧的生成直接相关,是造成大气环境质量下降及影响人体健康的重要因子。传统的VOCs监测方法时效低、周期长、指向性差、耗费人力物力。而VOCs走航监测的连续自动监测,能较准确地推测大气中VOCs污染物的来源以及预测污染物可能迁移的方向。VOCs走航监测技术不仅为环境管理部门提供了可靠的数据支持,也为VOCs污染的预防奠定了基础。Volatile organic compounds(VOCs)have a wide range of sources and complex composition,and are directly related to the formation of ozone in the lower atmosphere,which is an important factor causing the decline of atmospheric environmental quality and affecting human health.The traditional VOCs monitoring method has low time efficiency,long cycle,poor directivity,and consume human and material resources.Continuous automatic monitoring of VOCs can accurately predict the source of VOCs pollutants in the atmosphere and predict the possible migration direction of pollutants.VOCs navigation monitoring technology not only provides reliable data support for environmental management departments,but also lays a foundation for the prevention of VOCs pollution.
