EVALUATION OF THE MAJOR AIR POLLUTANTS LEVELS AND ITS INTERACTIONS WITH METEOROLOGICAL PARAMETERS IN ANKARA

Abstract

The aim of this study is to examine levels, temporal changes and interactions of major air pollutants with meteorological variables in Ankara, Turkey. The level of air pollutants namely PM10, PM2.5, SO2, NO, NO2, NOX, O3, CO was evaluated monthly, seasonally, and annually during 2019. The statistical relationship between air pollutants and ambient temperature, relative humidity and air pressure was examined and discussed. The pollutants concentrations started to rise in the morning and evening hours (excluding O3) when the traffic was at its peak and was in the highest level between 10:00 -14:00 and 22:00-02:00. It was seen at the lowest values (excluding O3) during daylight hours. A strong positive correlation was reported between PM10 and both PM2.5 and CO. Also, it was positive between NO and CO and NOX. On the other hand, negative correlation was reported between O3 and all other parameters. Moreover, paired comparisons of the selected parameters during the seasons were investigated. A statistically significant difference was found between different paired parameters namely CO/NOX, SO2/NOX and PM2.5/PM10. The results revealed that the changes in the meteorological parameters during the mentioned seasons has a significant impact on the behavior of air pollutant parameters.

ANKARA’DA BAŞLICA HAVA KİRLETİCİ SEVİYELERİNİN VE METEOROLOJİK PARAMETRELERLE ETKİLEŞİMLERİNİN DEĞERLENDİRİLMESİ

Abstract

Bu çalışmanın amacı, Ankara'daki başlıca hava kirleticilerin seviyelerini, zamansal değişimlerini ve meteorolojik değişkenlerle etkileşimlerini incelemektir. Başlıca hava kirleticilerinden olan PM10, PM2.5, SO2, NO, NO2, NOX, O3, CO seviyeleri 2019 yılı boyunca aylık, mevsimsel ve yıllık olarak değerlendirilmiştir. Hava kirleticileri ile ortam sıcaklığı, bağıl nem ve hava basıncı arasındaki istatistiksel ilişki incelenmiş ve tartışılmıştır. Kirletici konsantrasyonları trafiğin en yoğun olduğu sabah ve akşam (O3 hariç) saatlerinde yükselmeye başlamış ve en yüksek düzeyde 10:00 -14: 00 ile 22: 00-02: 00 arasında olmuştur. Gündüz ise en düşük değerler (O3 hariç) görülmüştür. PM10 ile hem PM2.5 hem de CO arasında güçlü bir pozitif korelasyon rapor edilmiştir. Ayrıca NO ve CO ve NOX arasında pozitif korelasyon görülmüştür. Diğer yandan O3 ile diğer tüm parametreler arasında negatif korelasyon rapor edilmiştir. Ayrıca mevsimlerde seçilen parametrelerin ikili karşılaştırmaları da incelenmiştir. CO/NOX, SO2/NOX ve PM2.5/PM10 gibi farklı eşleştirilmiş parametreler arasında istatistiksel olarak anlamlı bir fark bulunmuştur. Sonuçlar, söz konusu mevsimlerde meteorolojik parametrelerdeki değişikliklerin hava kirletici parametrelerinin davranışı üzerinde önemli bir etkiye sahip olduğunu ortaya koymuştur.
