EGZOS KİRLİLİĞİNE MARUZ KALAN KİŞİLERDE KAN KARBOKSİHEMOGLOBİN DÜZEYİ :

Bu çalışmada, karbonmonoksite (CO) meslekleri nedeni ile maruz kalan trafik polisleri, taksi şoförleri ve benzin dağıtıcılarının kan karboksihemoglobin (COHb) düzeylerinin araştırılması amaçlanmıştır. Kan örneklerinde COHb saturasyon yüzdelerinin tayini için spektrofotometrik yöntem kullanılmıştır. Yapılan analiz sonuçlarına göre; trafik polislerinde sigara içme alışkanlığı olanlarda (n=ll) ortalama %8.5+0.90 COHb, sigara içmeyenlerde (n-10) ortalama %5.32±0.26 COHb; taksi şoförlerinde sigara içenlerde (n=13) ortalama %6.75±0.68 COHb, sigara içmeyenlerde (n=7) ortalama %4.47+0.44 COHb; benzin dağıtıcılarında sigara içenlerde (n=ll) ortalama %7.12±0.58 COHb, sigara içmeyenlerde (n=9) ortalama %5.51±0.30 COHb; kontrol grubunda ise sigara içenlerde (n=30) ortalama %3.43+0.16 COHb, sigara içmeyenlerde (n=20) ortalama %0.88±0.05 COHb bulunmuştur

THE BLOOD CARBOXYHEMOGLOBIN LEVELS OF INDIVIDUALS OCCUPATIONALLY EXPOSED TO EXHAUST POLLUTION

The aim of this study was to determine the blood carboxyhemoglobin (COHb) levels of traffic policemen, taxi drivers and gas station employees who are exposed to traffic-related air pollution. Spectrophotometric method was used for the determination of carboxyhemoglobin saturation percent in blood samples. The mean COHb level of blood samples of traffic policemen was found to be 8.5±0.90 % for smokers (n=ll), 5.32+0.26 % for nonsmokers (n=10). İn taxi drivers, it was found to be 6.75+0.68% for smokers (n=13), 4.47±0.44% for nonsmokers (n=7) and in gas station employees carboxyhemoglobin levels of smokers (n=l 1) and nonsmokers (n=9) vere 7'.12+0.58% and 5.51+0.30%, respectively. Carboxyhemoglobin saturations in control group were 3.43+0.16% for smokers (n=30) and 0.88+0.05% for nonsmokers (n=20). According to the results of statistical evaluation, significant differences were found between COHb values of the control group and policemen, taxi drivers, gas station employees when compared separetely (p<0.001). Carboxyhemoglobin levels found in smokers were consistently higher than those in nonsmokers (p<0.05)
