In this study, in seasonalperiods in one year, it was examined the relationship between the particulatematter (PM10) concentration and meteorological data at themicro-climate conditions in Iğdır province. For this purpose, it was evaluatedrelative humidity, wind direction, wind speed, air pressure and air temperatureas meteorological data. In addition; the concentration of PM10 inair was taken into account as particulate matter pollution degree. Spearman'scorrelation test was applied in the factors, owing to having non-parametricproperties, to determine the relationship between the meteorological factorsand PM10 concentrations. The most effective meteorologicalparameters to the PM10 level were determined air pressure and windspeed in the winter and autumn, air humidity and wind direction in the spring,and also wind direction and wind speed in the summer. In addition, average amount of PM10was found 164.7 μgm-3, 84 μgm-3, 117 μgm-3,and 181 μgm-3 in winter, spring, summer and autumn periods,respectively, and also, the mean annual PM10 value was 182.23 μgm-3.When this value is taken into consideration, it is concluded that the PM10level in Iğdır province is much higher than 50 μgm-3, which is the24-hour PM10 limit value determined by the air quality assessment andmanagement regulation. This exceedance was observed during the year.

Bu çalışmada mikroklimaözelliğine sahip Iğdır ilinde meteorolojik faktörlerin partiküler kirlilik (PM10)miktarındaki değişimleri bir yıllık zaman periyodunda mevsimsel olarakincelenmiştir. Araştırmada bağıl nem, rüzgâr yönü, rüzgâr hızı, hava basıncı vehava sıcaklığı meteorolojik veriler; atmosferdeki PM10konsantrasyonu ise partiküler kirlilik düzeyi olarak dikkate alınmıştır.Faktörler parametrik olmayan özelliğe sahip olması nedeniyle Spearman’skorelasyon testine tabi tutularak birbirleriyle olan değişimleri belirlenmiştir.Yapılan korelasyon testi sonuçlarına göre il genelinde PM10değişimine kış ve sonbahar dönemlerinde; hava basıncı ve rüzgâr hızı,ilkbaharda; nem ve rüzgâr yönü, yaz periyodunda ise; rüzgâr yönü ve rüzgâr hızıen çok etkili olan meteorolojik parametreler olarak tespit edilmiştir. Ayrıcaortalama PM10 miktarının kış, ilkbahar, yaz ve sonbaharperiyotlarında sırasıyla 164.7 μgm-3, 84 μgm-3, 117 μgm-3ve 181 μgm-3 ve yıllık ortalama PM10 değerinin 182.23 μgm-3olduğu belirlenmiştir. Bu değer dikkate alındığında Iğdır ilindeki PM10düzeyinin, Hava Kalitesi Değerlendirme ve Yönetimi Yönetmeliğinin belirlemişolduğu 24 saatlik PM10 limit değeri olan 50 μgm-3’den çokdaha fazla olduğu sonucuna varılmıştır. Bu aşım yılın tüm günlerindegözlenmiştir.
