“…The population of the Ljubljana conurbation is estimated to be around 500,000, with 71% of the travel to work being conducted with a car (Pelko et al, 2010). Previous research (Ogrin, 2007) has identified a NO x air pollution hotspot in the city center, a street-canyon section of Slovenska Street. The Ljubljana municipality has closed a 400 m section of Slovenska Street on 22 September 2013 for all traffic except public buses and taxis as an abatement measure (Fig.…”

h i g h l i g h t sEffect of air quality plans on black carbon concentrations has been evaluated. Black carbon concentrations were reduced by limiting traffic to public transport. Reorganization of bus routes and renewal of the bus fleet improve air quality. a b s t r a c t Transport regulation at local level for the abatement of air pollution has gained significant traction in the EU. In this work, we analyze the effect of different transportation changes on air quality in two similarly sized cities: Granada (Spain) and Ljubljana (Slovenia). Several air pollutants were measured at both sites before and after the implementation of the changes. In Ljubljana, a 72% reduction of local black carbon (BC), from 5.6 to 1.6 mg/m 3 , was observed after the restriction was implemented. In Granada, statistically significant reductions of 1.3 mg/m 3 (37%) in BC and of 15 mg/m 3 (33%) in PM 10 concentrations were observed after the public transportation re-organization. However, the improvement observed in air quality was very local since other areas of the cities did not improve significantly. We show that closing streets to private traffic, renewal of the bus fleet and re-organization of the public transportation significantly benefit air quality.

“…Dlje kot smo od virov dušikovih oksidov, večji je delež dušikovega dioksida med dušikovimi oksidi in na koncu povsem prevlada. Nad mesti se ob visokih koncentracijah dušikovih oksidov oblikuje značilna, rdečkasto obarvana atmosfera, ki je izraziteje vidna ob nizkem Soncu pozimi (Ogrin, 2007).…”

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.

“…V Mestni občini Ljubljana je pri emisijah dušikovih oksidov po sektorjih na prvem mestu promet s 60 %, na drugem mestu pa so pretvorniki energije s 27 % (Cerkvenik, Persovšek, Podboj, 2010). Meritve dušikovega dioksida v gosti merilni mreži v preteklosti so že nakazale problem kakovosti zraka ponekod v Ljubljani (Ogrin, M., 2007;2008;Ogrin, D. in sod., 2006;Čemas, 2013) in potrdile upravičenost gostejših meritev. Prav tako so raziskave v različnih slovenskih okoljih pokazale, da prebivalci med glavnimi okoljskimi problemi, ki jim znižujejo kakovost bivanja, še vedno najpogosteje izpostavljajo hrup in onesnažen zrak, za oboje pa v največji meri krivijo prav promet (Vintar Mally, 2009).…”

IzvlečekV Ljubljani je glavni vir onesnaževanja zraka z NO 2 promet, zato se prispevek osredotoča na prometno obremenjevanje zraka v treh različnih tipih mestnega prostora: urbanem ozadju, na odprtem prostoru ob cestah in v cestnih koridorjih. Predstavljene so tudi meritve koncentracij prečno na glavno cesto. Prispevek primerja rezultate meritev NO 2 v Ljubljani v merilnih obdobjih poleti 2005 in 2013 ter skuša pojasniti vzroke za razlike v obsegu onesnaženosti različnih tipov mestnega prostora in pomemben upad koncentracij v vseh obravnavanih tipih.Ključne besede: onesnaževanje zraka, kakovost zraka, tipi mestnega prostora, dušikov dioksid, difuzivni vzorčevalnik, Ljubljana THE COMPARISON OF SUMMER AIR POLLUTION BY NITROGEN DIOXIDE IN LJUBLJANA BETWEEN 2005 AND 2013 AbstractIn Ljubljana, the air pollution by NO 2 is mainly caused by transportation.The article focuses on trafficrelated air pollution in three different types of urban space: urban back ground, open space near the roads, and street canyon. The measurement of concentrations perpendicular to the main city street is also presented. We compare the results of NO 2 measuring campaigns in Ljubljana during the summers of 2005 and 2013. We seek to explain the reasons for the differences in the pollution of diverse urban space types and for the significant decrease of concentrations in all types of urban space.
