Abstract:
Objective To get knowledge of the air pollution situation inside the car caused by the automotive components and decorative materials and the major impacting factors, and to provide the basis for the development of the car air pollution control and countermeasures. Methods Thirty-five cars of different types and ages were selected from January to July 2008. The concentration of benzene series compounds, formaldehyde and TVOC was determined, a survey and analysis of air pollution inside the car was conducted. Results The results showed that the air pollution inside the new cars was serious, with the increase of the using time, the concentration of pollutants reduced. The amount of formaldehyde emission inside the cars was related to the age of the car, the formaldehyde pollution inside the new cars was the most serious in one year. The longer the car was closed, the higher the concentration of pollutants would be. Using perfume or smoking inside the car, car washing or painting could increase the TVOC concentration inside the car. However, after purification treatment, the concentration of air pollutants inside the new cars could significantly decrease. Conclusion The air pollution inside the new cars is so serious, for the health of passengers and drivers, the related standards for the control of the air pollution should be set as soon as possible.
