Formaldehyde, Volatile Organic Compounds inside Newly Producted Vehicle and Neurobehavioral Performance of Vehicle Drivers
Abstract
Studies on the indoor air quality inside newly producted vehicle have made mainly mention of theconcentrations for indoor air pollutants or of subjective symptoms, such as irritated eyes and nose, headacheand dizziness. That is, there has been no report about how poor indoor air quality inside newly productedvehicle affects vehicle drivers. We measured the indoor air pollutants inside newly producted vehicle andevaluated the neurobehavioral performance of drivers, using a computerized neurobehavioral test (color wordvigilance), between a newly producted and a 11-year-old vehicle. Inside the newly producted vehicle, theformaldehyde concentration with closed window was 19.1㎍/m3. The concentration of VOCs with closedwindow was 3.9㎍/m3 for benzene, 316.7㎍/m3 for toluene, 20.5㎍/m3 for ethylbenzene, 47.7㎍/m3 form,p-xylene, 15.1㎍/m3 for o-xylene, and 15.3㎍/m3 for styrene. The neurobehavioral performance of driversinside newly producted vehicle with the computerized neurobehavioral test was 11.05% lower than that forthose inside 11-year-old control vehicle. These results suggest that the poor indoor air quality inside newlyproducted vehicle affects the neurobehavioral performance of driver and a proper evaluation of the indoorair quality inside newly producted vehicle is required into the health effects of pollutants with objective tool,in addition to the level of pollution.
