Abstract

Background & Objectives: Silica is one of the most air pollutant in workplaces which long-term occupational exposure to silica is associated with an increased risk for respiratory diseases such as silicosis. Silicosis is an OXIDATIVE STRESS related disease and can lead to the development of lung cancer. This study aims to analysis of ENDOGENOUS ALKANES and aldehydes in the exhaled breath of workers exposed to silica containing dusts.Methods: In this study, the exhaled breath of 20 workers exposed to silica containing dust (case group), 20 healthy non-smokers and 25 healthy smokers (control group) were analyzed. The breath samples using 3-liter Tedlar bags were collected. The volatile organic compounds (VOCs) were extracted with solid phase micro-extraction (SPME) and analyzed using gas chromatography-mass spectrometry (GC- MS).Results: Totally, thirty nine VOCs were found in all breath samples (at least once). Aldehydes and alkanes such as acetaldehyde, hexanal, nonanal, decane, pentadecane, 2-methle propane, 3-methyle pentane and octane were detected in the exhaled breath subjects. Among the these compounds, mean peak area of acetaldehyde, hexanal, nonanal, decane and pentadecane were higher in the exhaled breath of an case group than control groups (Pvalue<0.05). Conclusion: The use of EXHALED BREATH ANALYSIS as well as new media in the occupational toxicology and exposure biomarker assessment studies. It seems that acetaldehyde, hexanal, nonanal, decane and pentadecane can be considered as useful breath biomarkers for exposure assessment of silica containing dust. However, additional studies are needed to confirm thes results.
