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-f003: Monthly changes of CO (µg/m3) during the study period (Jan 2002–Dec 2010).

Mentions: The mean monthly changes in air pollutant parameters (SO2, CO, NO, NO2 and NOx) for the period 2002–2010 are displayed in Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, respectively. The seasonal changes in SO2 are clearly shown in Figure 2. The level of SO2 present in the city atmosphere was observed to increase during the winter months and decrease during summer. This is thought to result from the burning of fossil fuels for heating during winter. The mean concentration of SO2 throughout the study was determined as 16.6 µg/m3on the European side of the city and as 10.9 µg/m3 on the Asian side. The variations in CO concentration displayed similarities to those of SO2 concentration (Figure 3). The mean concentration for CO on the European side was 1103.4 µg/m3, compared with 963.6 µg/m3 on the Asian side. The highest CO concentrations were measured in March 2003 (month 15 of Figure 3) on the European side, and in January 2002 on the Asian side (month 1 of Figure 3).
