Long term variations of the atmospheric air pollutants in Istanbul City.

Ozcan HK - Int J Environ Res Public Health (2012)

Bottom Line: This study investigated long-term changes in air pollutant parameters (SO(2), CO, NO, NO(2), NO(x)) in Istanbul City, Turkey, using data from air-quality measurement stations on the Asian and European sides of Istanbul.The results show decreases from 2002 to 2010 in the amounts of SO(2) (one of the main pollutants released as a result of the burning of fossil fuels) and CO (indicative of incomplete combustion).However, NO(x) concentrations showed fluctuations over time, rather than a steady decline throughout the study period.

ABSTRACT
High population density and intense industrial activity has resulted in various forms of pollution in megacities. Air pollution ranks at the top of this list. This study investigated long-term changes in air pollutant parameters (SO(2), CO, NO, NO(2), NO(x)) in Istanbul City, Turkey, using data from air-quality measurement stations on the Asian and European sides of Istanbul. The results show decreases from 2002 to 2010 in the amounts of SO(2) (one of the main pollutants released as a result of the burning of fossil fuels) and CO (indicative of incomplete combustion). However, NO(x) concentrations showed fluctuations over time, rather than a steady decline throughout the study period.

ijerph-09-00781-f001: Study area and the air pollution stations.

Mentions: Istanbul is located in northwestern Turkey within the Marmara Region. The Bosphorus, which connects the Sea of Marmara to the Black Sea, divides the city into a European side, comprising the historic and economic centers, and an Asian, Anatolian side (Figure 1). Apart from being the largest city and former political capital of the country, Istanbul has always been the centre of Turkey’s economic life because of its location at the junction of international land- and sea-trade routes. According to the Turkish Statistical Institute, Istanbul is the most crowded city in Turkey with a population of 13.6 million [25]. Istanbul is also Turkey’s largest industrial centre; it employs approximately 20% of Turkey’s industrial labor and contributes 38% of Turkey’s industrial workspace.
