To reach this conclusion, Scottish researchers studied the indoor air quality of the cars of 17 drivers, including 14 smokers. As a first step, they installed fine particle sensors at the back of the vehicles, at the supposed height of the respiratory tract of a child. Then they asked the drivers to make their usual trips, for a period of three days.
At the end of this study, the 17 motorists had recorded 104 trips, including 63 while smoking. And on average, the volume of fine particles was around 7.4 μg / m3 during non-smoking journeys and 85 μg / m3 during smoking trips. That is to say a concentration of fine particles three times higher than the indoor pollution standard set by the World Health Organization! The study also shows that the use of ventilation or the fact of opening the windows to ventilate the passenger compartment had little impact on this pollution of the air inside the car.
