Controlling Strategies and Technologies of Volatile Organic Compounds Pollution in Interior Air of Cars

In interior air environment of cars, the mass concentrations of volatile organic compounds (VOC) are so high that human health is threatened. Their sources are analyzed and the controlling strategies and technologies are discussed. Reduce interior temperature, enhance vehicle ventilation, control interior materials, clean air-conditioning on time and use photo catalytic oxidation or adsorptive technology are the effective manners to lower their pollution levels. Some suggestions are given to manufacturers, government, vehicle occupants or car owners to abate in-car VOC exposure or harm.
