Abstract

Smog chambers are the effective tools for studying formation mechanisms of air pollution. Simulations by traditional smog chambers differ to a large extent from real atmospheric conditions, including light, temperature and atmospheric composition. However, the existing parameters for mechanism interpretation are derived from the traditional smog chambers. To address the gap between the traditional laboratory simulations and the photochemistry in the real atmosphere, a vehicle-mounted indoor-outdoor dual-smog chamber (JNU-VMDSC) was developed, which can be quickly transferred to the desired sites to simulate quasi-realistic atmosphere simultaneously in both chambers using “local air”. Multiple key parameters of the smog chamber were characterized in the study, demonstrating that JNU-VMDSC meets the requirements of general atmospheric chemistry simulation studies. Additionally, the preliminary results for the photochemical simulations of quasi-realistic atmospheres in Pearl River Delta region and Nanling Mountains are consistent with literature reports on the photochemistry in this region. JNU-VMDSC provides a convenient and reliable experimental device and means to study the mechanism of atmospheric photochemical reactions to obtain near-real results, and will make a great contribution to the control of composite air pollution.

车载双烟雾室:表征及其在准真实大气中光化学过程进化模拟中的初步应用

烟雾室是研究空气污染形成机制的有效工具。传统烟雾室的模拟在很大程度上不同于真实的大气条件，包括光照、温度和大气成分。然而，现有的机制解释参数是从传统的烟雾室中推导出来的。为了解决传统实验室模拟与真实大气中光化学之间的差距，开发了一种车载室内外双烟雾室（JNU-VMDSC），该烟雾室可以快速转移到所需的地点，使用“局部空气”在两个室内同时模拟准真实大气。对烟雾室的多个关键参数进行了表征，表明JNU-VMDSC符合一般大气化学模拟研究的要求。此外，珠江三角洲和南岭地区准真实大气光化学模拟的初步结果与该地区光化学的文献报道一致。JNU-VMDSC为研究大气光化学反应机理提供了一种方便可靠的实验装置和手段，以获得接近真实的结果，将为控制复合空气污染做出巨大贡献。

期刊介绍： Journal of Environmental Sciences is an international peer-reviewed journal established in 1989. It is sponsored by the Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, and it is jointly published by Elsevier and Science Press. It aims to foster interdisciplinary communication and promote understanding of significant environmental issues. The journal seeks to publish significant and novel research on the fate and behaviour of emerging contaminants, human impact on the environment, human exposure to environmental contaminants and their health effects, and environmental remediation and management. Original research articles, critical reviews, highlights, and perspectives of high quality are published both in print and online.
