Pollution of the air by gases (nitric oxide, nitrogen dioxide, nitrogen oxides) and particulate matter is a matter of everyday life. Particulate matter (PM) is one of hazardous pollutants causing deterioration of the environment and thus quality of life of the population. Long-term exposure to effects of increased concentrations of gaseous pollutants can also cause deterioration of the environment and human health. Particulate matter and gases production by road transport is a burning issue, particularly for larger urban areas. However, pollution also occurs outside urban areas from different sources (road transport) that primarily affect vegetation and animals living in the given areas. The environment in urban areas can be affected secondarily by a long-range transfer of pollutants. Due to the dominant use of combustion engines, exhaust gases contain large amounts of gaseous pollutants as well as particulate matter. They particularly include a large amount of the finest PM fractions, which can remain in the air for a long time, easily enter respiratory tracks, and damage human health. The other part includes particulate matter produced by the friction of different parts of roads and vehicle fleets, which concerns matter of larger aerodynamic diameters. The aim of the presented part of the work is to monitor production of particulate matter and gaseous pollutants along roads in rural areas and evaluate their inter-relations, while taking into account the monitored meteorological characteristics and traffic volume.
Keywords: Particulate matter, gaseous pollutants, meteorological characteristics, traffic volume, regression analysis.
