The exhaled carbon monoxide levels, respiratory function tests and the blood oxidative stress levels of the petrol station workers

Abstract

The aim of the study is to determine the occupational and environmental risk of the petrol station workers due to detecting the exhaled carbon monoxide, blood oxidative stress level and pulmonary function test. This study was carried out in Ankara in Turkey. A total of 98 individuals including 55 pump employees and 43 office employees were included in the study. A questionnaire consists of 25 question filled with participants face to face. Participants9 exhaled carbon monoxide levels were measured with a portable carbonmonoxidemeter, then pulmonary function tests were performed with a portable spirometer. 3 cc blood was taken from each participant to measure levels of oxidative stress. Blood results were compared with the results of 50 individuals without comorbid disease. 98 individuals were included in the study, 91 (%92,9) of whom were male. 55 of these individuals work as pump employees, 43 were working in the office. There was no significant difference between two groups in terms of exhaled carbonmonoxide levels, FEV 1 , FVC, FEV 1 /FVC , PEF and MEF 25-75% and the levels of oxidative stress parameters ; TAS, TOS, PON, SPON, ARE and OSI. Petrol station workers9 blood TAS, TOS and OSI levels were significantly higher than control blood levels (p Results of this study showed that there was no difference between working in the office or at pump at the petrol stations in terms of the levels of exhaled carbonmonoxide , pulmonary function tests and blood oxidative stress. But the levels of TAS and TOS with increased OSI levels in petrol station workers showing increased oxidative stress were measured higher than the control group.
