Evaluation of particle concentration in a diesel car : exposure of driver and passengers

Our study is part of the field of Internal Environmental Quality (IEQ) of confined atmospheres. Its essence is to position the level of particle pollution in a diesel powered car. As a comparative analysis compared to the normative data, this study makes it possible to highlight the exposure of the driver and the passengers and to evaluate the health risk posed by the detected levels. Methods. In order to highlight the level of exposure to particles, drivers and users of cars, we conducted an experiment to quantify particle concentrations in a diesel vehicle in a static position following a protocol highlighting the influence of starting the engine. A metrology was implemented, mobilizing two different particle counters (GRIMM and OPC ALPHASENSE). Conclusions. The various measurements show that the levels of exposure to PM1 particles are low in both cases and in good safety conditions against the standards. The levels measured pose no risk to the health of users.
