Bu çalışmada, İstanbul'un kentsel bir yerleşim
bölgesinde gaz ve partikül fazında ortam havası organoklorlu pestisit (OCP)
seviyeleri araştırılmıştır. Örnekler, kış aylarında on dört gün boyunca yüksek
hacimli örnekleyici kullanılarak toplanmıştır. Bireysel OCP konsantrasyonları partikül
fazı için 13 ila 593 pg.m-3 ve gaz fazı için 14 ila 1.748 pg.m-3
arasında değişmiştir. Gaz ve partikül fazlarındaki her OCP'nin ortalama konsantrasyon
toplamı sırasıyla 3,219 ve 2,746 pg.m-3 olarak tespit edilmiştir.δ
–HCH’nin en yüksek bireysel konsantrasyona sahip olduğu gözlemlenmiştir.
DDT'lerin bulunma oranları şu sırada olduğu görülmüştür: 4.4'-DDT>
4.4'-DDD> 4.4'-DDE. Σ (gaz + partikül) OCP konsantrasyonları 1,845 ila 10,196
pg.m-3 arasında değişim göstermiştir. Yüksek konsantrasyonların
gözlemlendiği günlerde hava kütlelerinin yörüngeleri HYSPLIT modeli ile
incelenmiştir.Gaz/partiküldağılımınınakıbetini belirlemek üzere logKp-logPL0
modeli uygulanmıştır.Regresyon eğrisinin ortalama eğimi -0.35 iken, kesim noktası
-2.89 olarak bulunmuştur.
In this study, gas and particle phase ambient
organochlorine pesticide (OCP) levels were investigated atan urban site in
Istanbul. Samples were collected by a high-volume sampler for fourteen days in
winter. Individual OCP concentrations were between13 and 593 pg.m-3 for
particle phase and 14 and 1,748 pg.m-3 for
gaseous phase. The sums of the average concentration of each OCP in gaseous and
particle phases were 3,219 and 2,746 pg.m-3,
respectively. δ-HCH had the highest individual concentration. The abundance of DDTs followed the order 4.4'-DDT
> 4.4'-DDD > 4.4'-DDE.The Σ(gas+particle)OCP
concentrations ranged between 1,845 and 10,196 pg.m-3. On the
days when high concentrations were observed, the trajectories of air masses
were investigated by the HYSPLIT model. logKp
versus logPL0 model was applied in order to determine the
fate of gas/particle partitioning. The average slope of the regression line was
-0.35, whereas the intercept was -2.89.
