People spend the most of their time in vehicles today due to
traffic congestions, occupational reasons and travelling. Volatile organic
compounds (VOC) are constantly emitted from the vehicle cabin materials such as
plastic, glass, sealants, foam, and upholstery. Considering the cabins are smaller
environments in comparison to other indoor spaces, the emission density would
be higher in contrast. Therefore, it is essential to measure these emissions to
better understand their health effects.
In the last decade, the market share of electric vehicles (EV) has
been increasing dramatically due to environmental response and advancement in
the proprietary technology. Since EVs work without a combustion engine, the VOC
emissions related to exhaust inside the cabin are expected to be reduced significantly.
However, cabin material emissions are still present without the background
noise of exhaust emissions. Meanwhile, most of the published studies focused on
the exhaust emissions in the cabin and lack to address how the transient
emissions occur, and in which events, such as ventilation and temperature
changes, the emissions are affected. These gaps are due to the low time
resolution and instrumental sensitivity.
