Abstract:Investigate the characteristics of chemical and particulate pollutants from cabin materials, equipment, supplies, human bodies and air quality emergency under the cabin condition with complex air flow, pressure, temperature and relative humidity. Determine the types and quantity of reaction products induced by ozone under cabin condition. Develop an accurate model for the pollutants emission and transport in the cabin, and transport inside human body. based on the above objectives, we have divided the project into the following five tasks: (1)VOC emission mechanisms & characteristics. (2)Particle dynamics & transport. (3)Ozone and cabin air chemistry. (4)Human exposure & integrated modeling. (5)Cabin environment and health In 2013, Tasks (1) ~ (5) were performed and summarized in this report, of which Task (5) was in the initial stage.
Key Words:Cabin environment; Volatile organic compounds; Particle; Health
