英文摘要	Potential health effects of material emissions in new motor vehicles are of great public concern in China. To estimate the pollution levels, air samples were taken from 802 new cars parked in a well-ventilated underground parking garage in Beijing, China. These vehicles were all manufactured in and after 2003, and represented 3 different price ranges. For comparison, 20 older vehicles (manufactured be-fore 2003) were also examined. Monitoring items included benzene, toluene, xylene, and formaldehyde. Preliminary results indicate that 82 percent of the vehicles studied had toluene levels exceeding the Chinese National Indoor Air Quality Standard. For benzene, xylene, and formaldehyde, the rates of non-compliance were 75, 25, and 24 percent, respectively. For all the pollutants, newer vehicles had higher concentrations than older ones. There seems a connection between the types of interior materials used in the passenger cabins and the concentrations of certain air pollutants.; Construction & Building Technology; Engineering, Environmental; Public, Environmental & Occupational Health; CPCI-S(ISTP); 0
