Measurements of black carbon and nitrogen dioxide concentrations in Lavrica and Kranj

Onesnaženost zraka v urbanih območjih je pomemben dejavnik kakovosti življenja, nesporen pa je tudi vpliv kakovosti zraka na zdravje ljudi. Med pomembna onesnaževala urbanega ozračja že desetletja uvrščamo dušikov dioksid (NO2), po letu 2000 pa se vse več raziskav posveča tudi črnemu ogljiku (BC). V prispevku predstavljamo stacionarne in mobilne meritve črnega ogljika ter stacionarne meritve dušikovega dioksida v urbanem območju na dveh primerih. V prvem primeru gre za ugotavljanje vpliva ceste na kakovost zraka v neposredni okolici vrtca in nekdanje osnovne šole na Lavrici, v drugem primeru pa so prikazani rezultati meritev črnega ogljika na cestnem omrežju Kranja v gosti prostorski mreži.Air pollution in urban areas has an important influence on quality of life, and the impact of air quality on human health is undeniable. Nitrogen dioxide (NO2) has been one of the main pollutants in the urban atmosphere for decades, and since 2000, an increasing amount of research has also focused on black carbon (BC). In the paper we look at two urban case studies, presenting stationary and mobile measurements of black carbon as well as stationary measurements of nitrogen dioxide. The first case examines the impact of road traffic on air quality in the immediate vicinity of a kindergarten and former primary school in Lavrica, and the second case presents results of monitoring of black carbon within the Kranj road network using a dense spatial network of sensors
