Two urn ir monitorin sttions re operted y te lol Environmentl Protetion Lortory in te ity. Te onentrtion dt of mjor ir pollutnts (CO, NO x, SO 2, C 6H 6, O 3, PM 10, PM 2.5), PM 10-ound evy metls (P, Cd, As nd Ni) nd some polyyli romti ydrorons (PAHs) inludin enzo()pyrene (BP), enzo()ntrene, sum of tree enzofluorntene (, nd j) isomers, indeno(1,2,3-d)pyrene nd dienzo(,)ntrene re ville for te ssessment sed on te ltest pulised monitorin dt of te Hunrin Air Qulity Monitorin Networ. Te levels of pollutnts were ompred wit te Hunrin nd EU limit or tret vlues defined for elt protetion nd te WHO ir qulity uidelines (AQGs) or estimted referene levels (RLs). Moreover, te ir qulity index vlues for te pollutnts were lulted. Te results indited tt te min pollutnts were BP, PM 10 nd PM 2.5 in te Győr tmospere. Te nnul men onentrtion of PM 10 nd PM 2.5 erosols reed te WHO AQGs (20 nd 10 µ/m 3 ), wile tt of te BP it ws out 5.5 times ier tn te WHO RL vlue of 0.12 n/m 3. However, ood or exellent ir qulity ws identified for ll exmined ir pollutnts sed on te onentrtion dt evluted y te Hunrin nd EU limit or tret vlues. Keywords: Urn, Air Qulity, Monitorin, Air Pollutnts. 1. Introdution Urn ir pollution is n environmentl prolem in mny ities round te world tt s serious immedite nd lonterm implitions for te elt of te popultion nd for te pysil environment [1] [8]. It is well-nown tt ir qulity in ities is te result of omplex intertion etween nturl nd ntropoeni environmentl onditions [1] nd [6] [8]. Moreover, te ir pollution pt of te urn tmospere onsists of emission nd trnsmission of ir pollutnts. Nowdys, emissions from motor trffi or different etin systems re very importnt soure roups trouout te world [8] [10]. However, tere re mny oter ntropoeni ir pollution soures in te ities (e.. power plnts, oil refineries, industril filities, ftories nd wood urnin fireples). Nturl soures su s wind-lown dust, wildfires nd volnoes lso ve n importnt influene on ir qulity. Te riulturl setor is lso soure of ir pollution, ut it is lso impted y ir pollutnts [8]. Durin trnsmission, ir pollutnts re dispersed, diluted nd sujeted to potoemil retions [1]. Mny ir qulity stndrds re used to ssess sinle ir pollutnts, e.. NAAQS (Ntionl Amient Air Qulity Stndrds) in USA dopted y te Environmentl Protetion Aeny, WHO AQGs (World Helt Orniztion Air Qulity Guidelines), EU-stndrds in Europe or own stndrds in te different ountries [6] [8] nd [11]. In worldwide, te onentrtions of te most importnt pollutnts (minly CO, NO 2, O 3, prtiulte mtter (PM), P nd SO 2) re routinely reorded t offiil ir qulity monitorin sttions euse of exposure to elevted onentrtions of mient ir pollutnts uses dverse umn elt effets [6] [8] nd [11]. However, it nnot e neleted tt umn eins in ities re exposed not to sinle ir pollutnt lone, ut to mixture of different sustnes. Additionlly, Air Qulity Index (AQI) is lso pplied for te ssessment of te ir pollution onditions in ities [11] [14]. Tere re mny ir qulity indies in use in te world. Commonly, different ountries ve teir own ir qulity indies (wit different denomintions), orrespondin to different ntionl ir qulity stndrds. Te mesurement of te most importnt ir pollutnt onentrtions in Hunry is importne for numer of resons relted to umn elt, te environment nd ompline wit EU leisltion. Te Hunrin Air Qulity Monitorin Networ (HAQMN) provides urrent nd istoril ir qulity monitorin dt ntionwide [15] nd [16]. Te networ onsists of two myor prts: utomti monitorin sttions wit ontinuous mesure of wide rne of ir pollutnts in AWSPT 112-1

2 mient ir, nd mnul system wit smplin points nd onseutive lortory nlysis. Te ir monitorin sttions in Hunry re operted y te Environmentl Protetion Lortories of County Government Offies. A prt of te mesured dt is reistered in te Europen ir qulity dtse mintined y te Europen Environment Aeny [8]. Te min ojetive of tis wor is to evlute te ir qulity in Győr (Hunry) on te ses of te reported ir pollutnt monitorin dt for te yer 2016 provided y te Hunrin Meteoroloil Servie (HMS) under te HAQMN. Tis study ives rief overview of te mesured pollutnts, onentrtion levels nd ir qulity sttus of te ity. Te onentrtions of te mesured pollutnts were ssessed y te Hunrin nd EU ir qulity stndrds nd WHO AQGs or referene levels (RLs). Te Hunrin AQI ws lso pplied for te ssessment. 2. Mteril nd Metods 2.1. Study Are Győr is te most importnt ity in nortwest Hunry, te pitl of Győr-Moson-Sopron County. It s eome one of te lrest eonomi, industril nd trffi res of Hunry. It s n urn popultion of 130,000 [17] [19]. Tere re two permnent ir monitorin sttions in Győr under te HAQMN. Te lotion of te sites is sown in Fi. 1. Te Site-1 (S1) is loted lon one of te usiest rods in te entre of te ity ner te us nd trin min sttions. Te Site-2 (S2) is loted pproximtely 3 m sout of te ity entre [17] [19].
