摘要

本研究是抽煙者對家庭內空氣品質及其家人暴露於呼吸性微粒與尼古丁的影響，1991年夏季及冬季在臺灣鄉村地區，選取七個抽煙家庭每天測量呼吸性微粒及尼古丁濃度，各為期一個星期。從這七個家庭中又找出14個人做抽煙家庭呼吸性微粒及尼古丁濃度暴露量評估。呼吸性微粒是利用以旋風式集塵器為採樣頭的個人呼吸採樣幫浦（流量為1.91/min）收集在聚氯乙烯濾紙，而尼古丁是利用有玻璃纖維的鐵氟龍濾紙裱敷硫酸氫鈉加以收集，經氨化庚烷萃取後，以氣相層析儀－氮磷偵測器分析。研究結果顯示兩季的室內呼吸性微粒濃度(44-107µg/立方公尺)都比室外(27-92µg/立方公尺)高，夏季室內尼古丁濃度平均為0.7±0.6µg/立方公尺，個人尼古丁暴露量則為0.5±0.5µg/立方公尺，冬季室內尼古丁濃度平均為0.7±1.1µg/立方公尺，個人尼古丁暴露量則為0.4±0.5µg/立方公尺。相關性分析顯示，室內呼吸性微粒是趨向由室外道路粉塵產生而較少來自二手煙。

This study examines smoker's impact on his indoor air quality and his relative exposure to respirable particulate and nicotine. The daily indoor/outdoor respirable particulate and nicotine concentrations of seven smoker's homes were concurrently measured over a week in a rural area of Taiwan in the summer and the winter. Personal exposures to respirable particulate and nicotine of sixteen members from these seven families were also measured. Respirable particulate samples were collected on PVC filters by personal pumps with cyclone (flow rate=1.9l/min). Nicotine samples were actively collected on the teflon coated glass fiber filters impregnated with sodium bisulfate, extracted by ammoniated heptane, and analyzed by the gas chromatographic method. Indoor respirable particulate concentrations (44 to 107µ/m^3) were higher than outdoor (27 to 92µ/m^3) in both the summer and winter. In summer, the nicotine concentrations averaged at 0.7±0.6µ/m^3 indoors and about 0.5±0.5µ/m^3 for personal exposure. In winter, the nicotine concentrations averaged 0.7±1.1µ/m^3 indoors and about 0.4±0.5µ/m^3 for personal exposure. From correlation analysis, the indoor respirable particulates appeared to be generated from outdoor road dust rather from environmental tobacco smoke.
