Abstract

In this study, in seasonal
periods in one year, it was examined the relationship between the particulate
matter (PM₁₀) concentration and meteorological data at the
micro-climate conditions in Iğdır province. For this purpose, it was evaluated
relative humidity, wind direction, wind speed, air pressure and air temperature
as meteorological data. In addition; the concentration of PM₁₀ in
air was taken into account as particulate matter pollution degree. Spearman's
correlation test was applied in the factors, owing to having non-parametric
properties, to determine the relationship between the meteorological factors
and PM₁₀ concentrations. The most effective meteorological
parameters to the PM₁₀ level were determined air pressure and wind
speed 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 PM₁₀
was 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 PM₁₀
level in Iğdır province is much higher than 50 μgm^-3, which is the
24-hour PM₁₀ limit value determined by the air quality assessment and
management regulation. This exceedance was observed during the year.

Mikroklima Özelliğine Sahip İklim Koşullarında Meteorolojik Verilerle İlişkili Partiküler Kirlilik (PM10) Karakteristikleri: Iğdır Örneği

Abstract

Bu çalışmada mikroklima
özelliğine sahip Iğdır ilinde meteorolojik faktörlerin partiküler kirlilik (PM₁₀)
miktarındaki değişimleri bir yıllık zaman periyodunda mevsimsel olarak
incelenmiştir. Araştırmada bağıl nem, rüzgâr yönü, rüzgâr hızı, hava basıncı ve
hava sıcaklığı meteorolojik veriler; atmosferdeki PM₁₀
konsantrasyonu ise partiküler kirlilik düzeyi olarak dikkate alınmıştır.
Faktörler parametrik olmayan özelliğe sahip olması nedeniyle Spearman’s
korelasyon testine tabi tutularak birbirleriyle olan değişimleri belirlenmiştir.
Yapılan korelasyon testi sonuçlarına göre il genelinde PM₁₀
değişimine kış ve sonbahar dönemlerinde; hava basıncı ve rüzgâr hızı,
ilkbaharda; nem ve rüzgâr yönü, yaz periyodunda ise; rüzgâr yönü ve rüzgâr hızı
en çok etkili olan meteorolojik parametreler olarak tespit edilmiştir. Ayrıca
ortalama PM₁₀ miktarının kış, ilkbahar, yaz ve sonbahar
periyotlarında sırasıyla 164.7 μgm^-3, 84 μgm^-3, 117 μgm^-3
ve 181 μgm^-3 ve yıllık ortalama PM₁₀ değerinin 182.23 μgm^-3
olduğu belirlenmiştir. Bu değer dikkate alındığında Iğdır ilindeki PM₁₀
düzeyinin, Hava Kalitesi Değerlendirme ve Yönetimi Yönetmeliğinin belirlemiş
olduğu 24 saatlik PM₁₀ limit değeri olan 50 μgm^-3’den çok
daha fazla olduğu sonucuna varılmıştır. Bu aşım yılın tüm günlerinde
gözlenmiştir.
