The impact of the air exchange rate onto the concentration of pollutant particles in the car cabin

Air quality is determined by the content of pollutants in the ambient air. Air monitoring results show that air quality is improving in many areas. Nevertheless, most EU countries, including Slovakia, have long-term air quality problems, in particular as regards limit values for fine dust, fine particulate matter PM10, PM2.5 and nitrogen oxides NOx, as well as a target value for benzo(a)pyrene. The main causes of current air pollution are mainly emissions from domestic heating and emissions from transport, as well as high background concentrations (pollution where it is not possible to directly determine the source of emissions). Increased attention is paid to transport, which is considered to be one of the main factors in air pollution, and with the ever-increasing density of traffic, its impact on air quality needs to be monitored. Transport produces almost a quarter of greenhouse gas emissions and is a major cause of air pollution in cities. At the same time, it is necessary to deal with air quality in cars, which is affected by several factors. The aim of this article is to analyze the air quality in the car cabin. The influence of the fan setting and the state of the indoor environment on the particle concentrations will also be evaluated.
