Abstract

Pollutants such as particulate matter PM, nitrogen oxides and troposferic ozone are harmful to a human health. Study of pollutant variation and its relationship is of importance not only for environmental protection but also for the benefit of public at large. The aim of this study was to analyze seasonal and daily variation of PM10, NO2, NO and O3 in a residential part of an urban area. The study was conducted from January 1 till December 31, 2011 in the City of Mostar using the following methods: absorption of beta radiation, chemiluminescence and UV photometry. The results presented in this article, show the dependence of air pollution levels upon traffic density and seasons.
