Irak-Duhok'ta Petrol İstasyonların Çalışan İşçilerinin Mikronükleus Frekansı Üzerine Benzenin Etkisi

Amaç: Benzen başlıca organik ürünlerden biridir, bu organik ürüne kronik maruz kalan insanlar çeşitli sağlık sorunlarına maruz kalmaktadır. Bu çalışmanın amacı, Duhok eyaletindeki benzin istasyonu çalışanları arasında mesleki benzene maruz kalma ile ilişkili mikronükleus sıklığını değerlendirmektir. Materyal ve Metot: Çalışma gruplarına mesleki olarak maruz kalan 25 benzin istasyonu çalışanı dahil edildi ve aynı sayıda yaş olarak eşleştirilmiş kontrol alındı ve genetik hasar açısından değerlendirildi. Pul pul dökülmüş Buccal hücreleri her iki gruptan steril fırça kullanılarak toplandı. Etanol içinde sabitlenen ve Giemsa boyası ve 1000 hücre ile boyanmış lamlar bir ışık mikroskobu altında incelenmiştir. Student t - testi ve P

The Effects of Benzene on Micronuclei Frequency of Workers in Petrol Stations in Duhok- Iraq

The aim of this studywas to evaluate the micronuclei frequency associated withoccupational exposure to benzene among petrol stationworkers in Duhok Province.Materials and Methods: The study groups includedtwenty-five occupationally exposed petrol station workersand twenty five age matched controls were recruited andevaluated for genetic damage. Exfoliated Buccal cellswere collected from both groups by using the sterile brush.Slides fixed in ethanol and stained with Giemsa stain and1000 cells were studied by using a light microscope. Statistical analysis for data interpretation performed by Student’s t‑test, and P < 0.05 was considered statisticallysignificant. In this study, both Control and workers withhistory of Tobacco smoking and alcohol were excluded.Results: As compared to control subjects, significant highlevel of micronuclei frequency was found in the workersexposed to benzene (4.65±2 and 1.22±7 respectively).Period of exposure also showed considerable effects(P0.05).Conclusions: The results of our study concluded that benzene have the potential to increase micronuclei frequencyin the exposed subjects.nzene among petrol station workers in Duhok Province.Materials and Methods: The study groups included twenty-five occupationally exposed petrol station workers and twenty five age matched controls were recruited and evaluated for genetic damage.
