İZMİR HAVASINDAKİ PARTİKÜL MADDE KİRLİLİĞİ: ÖLÇÜM VE DEĞERLENDİRME
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.

THE AIR BORNE PARTICULATE MATTER POLLUTION IN İZMİR
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.
