Charakterystyka zanieczyszczenia powietrza atmosferycznego tlenkami azotu na obszarze aglomeracji warszawskiej ze szczególnym uwzględnieniem Ursynowa

The aim of this work was the characteristic of spatial and temporary distribution of nitrogen oxides concentration (NO2, NO) from 10 monitoring air pollution stations in Warsaw agglomeration. The measurements of 1-hour NOx (NO2, NO) concentration data were used. The results of analysis mean annual value of NO2 concentration in regarding stations situated in rural areas and Warsaw is included in 8,4 μg⋅m–3 (for Granica station) and 57,9μg⋅m–3 (for Komunikacyjna). Permissible concentration increased to tolerance level (52μg⋅m–3) for this period was overcome in Komunikacyjna station. In terms of Komunikacyja station concentration values are greater than values for reference stations more than twice (for Jarczew) and more than 20 times (for Puszcza Borecka).
