Determination of Atmospheric Concentrations of Benzo [a] Pyrene with Active Sampler in Erzurum City Center

Öz

Fifty one atmospheric air samples were collected from sampling station installed in a point where domestic heating was intensive at the city center of Erzurum from February 5 to April 7 in 2008. The atmospheric gas and particle phase concentration of Benzo [a] Pyrene (BaP) of which carcinogenic effect is more than the other PAH compounds were investigated by using Tecora hi-vol sampling instrument (average 0.320 m3 min-1). The rst 28 days of sampling period were between February 5 - March 15, while the other part, 23 days, were between March 16 - April 7. The average concentration of total (gas+particle) amount of BaP in the period of February- March was measured as 10.25 ± 9.18 ng m3, whereas it was measured as 4.45 ± 1.47 ng m3 in the period of March- April. Furthermore, the values of the daily and monthly concentration of BaP were compared with the literature and it was observed that the present values were close to the values in the regions with the same characteristics.

Erzurum Kent Merkezinde Aktif Örnekleyici ile Benzo [a] Pyrene’ nin Atmosferik Konsantrasyonlarının Belirlenmesi

Öz

Erzurum kent merkezinde yoğun evsel ısınmanın olduğu bir noktaya kurulan örnekleme istasyonundan 2008 yılının Şubat, Mart ve Nisan ayları arasında toplam 51 adet atmosferik hava örnekleri toplanmıştır. Tecora hi-vol örnekleme cihazı (ortalama 0.320 m3 dak-1) kullanılarak toplanan atmosferik hava örneklerinde PAH bile- şenlerinden kanserojenik etkisi diğerlerine göre daha fazla olan Benzo [a] Pyrene’ nin (BaP’ nin) Erzurum kent merkezinde atmosferik gaz ve partikül faz derişimleri araştırılmıştır. Örneklemenin 28 günü 5 Şubat - 15 Mart ayları arasında, 23 günüde 16 Mart - 7 Nisan ayları arasında yapılmıştır. BaP’ nin Şubat-Mart dönemi ortalama top- lam (gaz+partikül) konsantrasyon değeri 10.25 ± 9.18 ng m3 iken, Mart-Nisan örneklemesinde ise ortalama toplam (gaz+partikül) konsantrasyon değeri 4.45 ± 1.47 ng m3 ölçülmüştür. Ayrıca BaP’ nin günlük ve aylık konsantrasyon değişimleri literatürdeki diğer kent merkezleri ile karşılaştırılmış ve bulunan değerlerin aynı karakteristik özellik- lere sahip bölgeler için yakın değerler aldığı görülmüştür.
