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.摘要 I Abstract II 目錄 IV 表目錄 VI 圖目錄 VII 第1章 緒論 1 1.1 研究緣起 1 1.2 研究目的 1 第2章 文獻探討 2 2.1 揮發性有機物(VOLATILE ORGANIC COMPOUNDS, VOCS) 2 2.1.1 內生性揮發性有機物(Endogenous Volatile Organic Compounds) 2 2.1.2 甲醛(Formaldehyde,HCHO) 4 2.2 呼出氣體VOCS研究文獻探討 6 2.3 傢俱業VOCS研究文獻探討 7 第3章 研究方法 9 3.1 研究對象 9 3.2 實驗器材與設備 9 3.2.1 藥品和試劑 9 3.2.2 氣體和器材 10 3.2.3 實驗儀器 11 3.3 前處理流程 12 3.3.1 採樣管之填充 12 3.3.2 採樣管之保存 12 3.3.3 採樣管之調態 12 3.3.4 採樣管採樣之流量校正 13 3.3.5 採樣袋淨化 13 3.3.6 問卷設計 13 3.4 採樣流程 13 3.4.1 呼出氣體中VOCs 13 3.4.2 室內空氣之VOCs及甲醛 14 3.4.3 問卷填答 14 3.5 分析流程 14 3.5.1 上機前儀器調態 14 3.5.2 儀器空白之確認 15 3.5.3 分析步驟 15 3.6 儀器條件 16 3.6.1 甲醛分析儀(PPM Formaldemeter 400) 16 3.6.2 熱脫附裝置(O·I·Analytical Model 4560) 16 3.6.3 低溫濃縮捕集裝置(Cryo-Focus Model,CFM) 16 3.6.4 氣相層析儀(HP6890) 16 3.6.5 質譜儀(HP5973) 17 3.7 QA/QC 17 3.7.1 空白樣品(Blank Sample) 17 3.7.1.1 試劑空白(Reagent Blank Sample) 17 3.7.1.2 現場空白(Field Blank Sample) 17 3.7.1.3 運送空白(Trip Blank Sample) 17 3.7.2 重複分析(Duplicate Analysis) 18 3.7.3 品質管制圖 18 3.8 數據收集、處理及統計分析 18 3.9 研究架構 19 第4章 結果與討論 20 4.1 QA/QC 20 4.1.1 空白試驗 20 4.1.2 重複試驗 20 4.1.3 品質管制圖 21 4.2 定性分析 21 4.3 半定量分析(SEMIQUANTITATIVE ANALYSIS) 23 4.3.1 肺泡體積含量梯度(Alveolar Gradients) 23 4.4 個人暴露測定 24 4.4.1 環境空氣 24 4.4.2 呼出氣體 24 4.4.3 問卷調查 28 第5章 結論 30 參考文獻 32 附錄 76923721 bytesapplication/pdfen-US呼出氣體揮發性有機物傢俱業者甲醛肺泡體積含量梯度exhaled airvolatile organic compoundsfurniture sales department clerkformaldehydealveolar gradient傢俱業者呼出氣體中揮發性有機物之分析研究Volatile Organic Compounds in Exhaled Air of Furniture Sales Department Clerksthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/59807/1/ntu-94-R92844016-1.pdf
