An emissions inventory of primary air pollutants based on anthropogenic sources was prepared with 1-km spatial and 1-hour temporal resolution within an area of 85 km by 170 km centered on the metropolitan area of Istanbul, which is a megacity in Europe, as well as the economic, cultural, and financial center of Turkey. The emissions sources were broadly classified as industrial, vehicular and residential heating sources in a systematic manner. The emissions of five main pollutants, namely sulfur dioxide (SO 2 ), particulate matter (PM 10 ), carbon monoxide (CO), nitrogen oxides (NO x ) and nonmethane volatile organic compounds (NMVOCs), were estimated. Data on the activity levels of the various industries, fuel consumption in vehicles, and residential heating activities, along with the related emission factors from literature, were used for estimation of the emissions for the year 2007. The results show that SO 2 emissions primarily came from the use of lignite and fuel oil in industrial plants and residential areas. Industry was the most polluting sector with regard to SO 2 emissions, contributing about 83% of the total, while residential heating was the most polluting sector with regard to PM 10 emissions, contributing 51% of the total. Traffic was also the most polluting sector for NO x , NMVOC and CO emissions, with the contributions of 89%, 68% and 68%, respectively. With regard to PM 10 emissions, several sand and gravel processing plants, along with one big cement plant, were the main polluters in the metropolitan area.

a b s t r a c tThe objective of this study is to build a regression model of air quality by using the support vector machine (SVM) technique in the Avilés urban area (Spain) at local scale. Hazardous air pollutants or toxic air contaminants refer to any substance that may cause or contribute to an increase in mortality or serious illness, or that may pose a present or potential hazard to human health. To accomplish the objective of this study, the experimental data of nitrogen oxides (NO x ), carbon monoxide (CO), sulphur dioxide (SO 2 ), ozone (O 3 ) and dust (PM 10 ) for the years 2006-2008 are used to create a highly nonlinear model of the air quality in the Avilés urban nucleus (Spain) based on SVM techniques. One aim of this model is to obtain a preliminary estimate of the dependence between primary and secondary pollutants in the Avilés urban area at local scale. A second aim is to determine the factors with the greatest bearing on air quality with a view to proposing health and lifestyle improvements. The United States National Ambient Air Quality Standards (NAAQS) establishes the limit values of the main pollutants in the atmosphere in order to ensure the health of healthy people. They are known as criteria pollutants. This support vector regression model captures the main insight of statistical learning theory in order to obtain a good prediction of the dependence among the main pollutants in the Avilés urban area. Finally, on the basis of these numerical calculations, using the support vector regression (SVR) technique, conclusions of this work are drawn.
