Passenger exposure to volatile organic compounds (VOCs) emitted from vehicle interiors hasincreasingly drawn public concern over their potential health risks. This study aimed to investigate ambient levels of in-cabin VOCs in a new car over the period of one year after first delivery. The relationship between VOC concentrations and in-cabin temperature was also studied. Seventeen active air samplings inside a parked new car were conducted from February 2012 to February 2013 using sorbent tubes. Six VOCs were measured with first-month average concentrations of 215 µgm-3for benzene, 65.6 µgm-3for toluene, 151 µgm-3for 1,2,3-trimethylbenzene, 806 µgm-3for ethyl acetate, 183 µgm-3for formaldehyde, and 28.2 µgm-3for acetone. The concentration profiles of all VOCs except formaldehyde declined, falling below the detection limits towards theend of the 1-year monitoring period. Formaldehyde concentrations were found to be directly proportional to in-cabin temperature at a significance level of p=0.05 during the first five months.
