TEMPORAL AND SPATIAL VARIATION OF AIR POLLUTION İN BURSA, KOCAELİ AND YALOVA, TURKEY

Abstract

Air pollution is a serious environmental problem. The anthropogenic air pollutants have been intensified in the atmosphere of industrial and densely populated cities. The aim of this study was to reveal temporal and spatial pattern of air pollution in Bursa, Kocaeli and Yalova. Because the cities are a densely populated industrial city in Turkey. For this study, outdoor inhalable particles (measured as particulate matter-PM10), sulfur dioxide (SO2), nitrogen oxides (NO, NO2) and carbon monoxide (CO) data were used to put forward air quality for the period March 2013- December 2015. Data taken from four air quality monitoring station (Beyazit Street, Inegol, Kestel, Kultur Park, Uludag Universty, Alikahya, Golcuk, Korfez , İzmit Kandira, Yenikoy, Altinova and Armutlu) established by the Marmara Clean Air Center Directorate were used. The correlation between the PM10, SO2, NO, NO2, CO concentration, year and month has been investigated utilizing bivariate correlation methods. Inverse Distance Weight (IDWI) techniques were used to analyze the spatial distribution of all pollutants. As a result, annual SO2, PM10 and NO2 concentrations show a decreasing trend in the last years. However, NO and CO concentrations show a increasing trend. Also, the maximum SO2, PM10, NO2, NO, and CO concentrations peaked at the period of winter season. When the pollutants concentrations indicate higher values in city centers with high population intended for heating and around industrial enterprises (Bursa and Kocaeli).
