Influence of Road Traffic on Indoor Air Quality

The quality of air that people breathe has become a very important parameter of quality of life. Pollution contributes to numerous diseases, problems with the absorption of knowledge, and also reduces work efficiency. The article attempts to find the relationship between road traffic and indoor air quality. The parameter used to assess air pollution was particulate matter (smog). The research was carried out in three localisations with different traffic volumes, in three places for each localisation, in the summer, autumn, and winter periods. It was found that in areas with heavy road traffic, this traffic causes an inflow of pollutants into the rooms. In low – traffic localisations, sources other than road traffic have a greater impact on the indoor air quality, especially in the cool periods (autumn, and winter).
