Abstract
This study was aimed to analyze volatile organic compounds (VOCs) in exhaled air of furniture sales department clerks, and to observe the variation of VOCs from occupational exposure. In addition to exhaled air VOCs, formaldehyde and VOCs in the environmental air were also measured, and there relationship together with items in the questionnaire were discussed.
The study design was a cross-section study. The furniture sales department clerks were divided into common furniture sales department clerks and systematic furniture sales department clerks. Seventy-four volunteers were participated in this study, including twenty-nine in ordinary furniture sales department、twenty in systematic furniture sales department and twenty-five in control. The VOCs in exhaled air was collected in a Tedlar bag and was analyzed using thermal desorption GC/MS. Each compound was identified based on the mass spectrum using Wiley 275 mass spectra library, and semi-quantitative analysis was used to measure the alveolar gradient of each compound.
More than sixty compounds were detected, including alkanes, alkenes, ketones, furans, aromatics, sulfur-containing compounds, chlorine-containing compounds and nitrogen-containing compounds. Statistical analysis indicated that ten compounds in the exhaled air of non-smoking volunteers were significantly different among the three groups (p<0.05). Twenty-six compounds in the air, including ethylbenzene , 1,3-dimethyl-benzene and formaldehyde, were significantly different among the three groups (p<0.05).
The alveolar gradient of pentane in non-smoking volunteers was significantly different between the furniture sales department clerks and the control volunteers, and was significantly different with the relative abundance of ethylbenzene and 1,3-dimethyl-benzene in air. Thus, exhaled air pentane abundance may be influenced by ethylbenzene and 1,3-dimethyl-benzene in air.
