Abstract

The ambient air concentrations of particulate matter’s fractions (PM2.5 and PM10) were
determined concurrently at suburban and urban sites in Izmir, Turkey. The sampling season
was between June 2004 and May 2005. The mean concentrations of PM2.5 and PM10 were
24.2 ± 12.2 and 46.9 ± 20.1 µg m
-3
at the suburban site and 64.4 ± 38.5 and 80.0 ± 30.2 µg m
-
3
at the urban site, respectively. The mean summer concentrations of two fractions were
higher than winter ones at the suburban site; on the contrary, the concentrations at the urban
site in winter were higher than in summer. The relationships between meteorological
parameters such as wind direction, wind velocity and precipitation and the PM
concentrations were evaluated. It was obtained that the PM concentrations were notably
influenced by these parameters. It was also seen that PM2.5/PM10 ratio was affected by the
same parameters; and the temporal variation of PM2.5/PM10 ratio was significant, too. The
measured PM10 concentrations were compared to data obtained from four online stations
located in the city. The results indicated that the spatial variation of PM10 at the different sites
of the city was significant.

İZMİR HAVASINDAKİ PARTİKÜL MADDE KİRLİLİĞİ: ÖLÇÜM VE DEĞERLENDİRME

Abstract

İzmir havasındaki partikül madde konsantrasyonları (PM2,5 ve PM10), şehir merkezinde
(Yeşildere semti) ve yarı-kırsal özellikteki Dokuz Eylül Üniversitesi Tınaztepe Yerleşkesi’nde
eş zamanlı olarak bir yıl boyunca ölçülmüştür. Ölçüm dönemi Haziran 2004 ve Mayıs 2005
tarihleri arasıdır. PM2,5 ve PM10 ortalama konsantrasyonları Tınaztepe’de sırasıyla 24,1 ± 12,2
ve 46,9 ± 20,1 µg m-3
, Yeşildere’de 64,4 ± 38,5 ve 80,0 ± 30,2 µg m-3
, olarak ölçülmüştür.
Her iki partikül madde fraksiyonunda yaz konsantrasyonları Tınaztepe’de kış değerlerinden
yüksekken, Yeşildere’de tam tersi olmuştur. Partikül madde konsantrasyonlarının rüzgar
yönü, hızı, yağış gibi meteorolojik değişkenlerle ilişkisi irdelenmiş ve bu etmenlerin etkisinin
önemli boyutlarda olduğu belirlenmiştir.
