Abstract:	Onesnaženost zraka z delci PM10 je vedno večji problem predvsem v mestih in ponekod tudi v njihovi okolici. Trdni delci so onesnaževala, ki zaradi povečanih koncentracij vplivajo na zdravje ljudi. Na območju Celjske kotline so pomembni viri delcev različni industrijski obrati, kurišča, promet, resuspenzija in naravni viri. Na koncentracijo delcev PM10 vpliva tudi meteorologija, ki je v zimskem času neugodna (pogoste temperaturne inverzije). Ker dosedanje raziskave še niso ocenile vpliva suhega zapolnjevanja sadre iz proizvodnje titanovega dioksida na lokaciji Za Travnik na koncentracijo delcev PM10 je bil namen naloge, da se to področje podrobneje razišče in rezultate primerja z rezultati modelnega izračuna pred uvedbo postopka suhega zapolnjevanja. Zato so se v okolici na več lokacijah izvedle meritve koncentracij delcev PM10. Zbrani vzorci so bili analizirani in določena je bila njihova sestava. Podatki so bil obdelani z statističnim modelom faktorske analize, ki temelji na analizi osnovnih komponent PCA (principal component analysis) za določevanje virov. Z ekstrakcijo faktorskega prostora smo pojasnili 68 % (77 %) meritev ter določili vire onesnaževanja, ki najbolj prispevajo k izmerjenim koncentracijam PM10 delcev [2]. Na lokacijah bliže opazovanega območja (vzhodni rob Celjske kotline) je bilo določeno, da je prevladujoči vir industrija jekla in nekovinska industrija, sledi ji promet, resuspenzija in mešani viri kurišča in industrija. Na lokaciji, ki je bila še bolj vzhodno pa so bila določena kot glavni vir kurišča na biomaso, sledijo kurišča na olje in kmetijstvo nato industrijski viri in resuspenzija, soljenje cest in/ali daljinski vpliv morja. Med slednje smo uvrstili tudi vir suhega zapolnjevanja sadre, ki ne vpliva signifikantno na koncentracije delcev PM10. Rezultati pridobljeni z modelnim izračunom so pokazali enake prevladujoče smeri širjenja delcev, napovedane koncentracije delcev iz vira suhega zapolnjevanja so bile bistveno večje od dejansko izmerjenih, zaradi precenjenega indeksa imisije in predpostavke, da do prašenja prihaja nepretrgoma in brez protiprašnih ukrepov, ki se izvajajo pri dejanskem suhem zapolnjevanju [23].

Title:	Effect of dry filling gypsum on particle concentration pm10 in ambient air
Abstract:	Air pollution with particulate matter PM10 is a growing problem especially in urban areas and sometimes even in its surroundings. High concentrations of solid particles are source of pollution which has an impact on human’s health. On the area of Celje basin are important sources of particles of different industrial plants, firebox, transport, resuspension and natural resources. The concentration of PM10 particles also affects the meteorology, which is in the winter unfavorable (frequent temperature inversions). Since the findings so far did not evaluate the influence of dry filling gypsum from titanium dioxide production at the area Za Travnik on the concentration of PM10, the intent was to research and compare the results with the results of the model calculation, before the actual initiation of the process of dry filling. Therefore, in the vicinity in several locations were carried out measurements of concentrations of PM10. The collected samples were analyzed and it was determined their composition. Data have been processed by the statistical model of factor analysis, based on an analysis of the basic components of PCA (principal component analysis) to determine the sources. The extraction factor space we were explained 68% (77%) measurements and determine the sources of pollution that contribute most to the measured concentrations of PM10 [2]. At locations closer to the observation area (eastern edge of the Celje basin), it was determined that the predominant source of steel industry and the mineral industry, followed by transport, re-suspension and mixed sources firebox and industry. On the spot, which was further east have been identified as the main source of the firebox of the biomass, followed oilfurnance, agriculture and then industry sources and re-suspension. This category includes also a source of dry filling of gypsum, which does not impact significantly on the concentration of PM10. The results obtained by model calculation showed the same predominant direction of spread of particles predicted concentration of particles from the source of dry filling were substantially higher than actually measured, due to overvalued index emissions and the assumption that the dust comes continuously and without anti-dust measures implemented in the actual dry filling [23].
