本研究目的是以環境參數量測及生物氣膠採樣探討網咖內的空氣品質,提供後續改善的依據。以台南某兩家網咖為研究對象,利用單階、六階衝擊式生物氣膠採樣器、室內空氣品質監測器、光離子化監測器、甲醛監測器、氣膠微粒監測器量測相關參數,所得參數測定結果與台灣室內空氣品質標準作比較,同時以噴灑乙醇的方式搭配光離子化監測器進行量測,評估通風換氣有效性。另外針對禁菸前後網咖空氣品質之差異性進行室內空氣品質評估。結果顯示:(1)網咖吸菸區及非吸菸區環境中CO2濃度絕大多數均超過我國室內空氣品質建議值;(2)真菌的I/O ratio皆小於1,細菌的I/O ratio皆遠大於1;(3)真菌及細菌的粒徑分佈範圍分別介於1.1~2.1 m 及2.1 ~4.7 m之間;(4)懸浮微粒之粒徑以PM2.5及PM1.0為主;(5)禁菸後CO、懸浮微粒濃度皆有下降(p<0.05),但依然超過我國室內空氣品質建議值,且CO2濃度因消費人數增加而上升;(6)網咖內每小時空氣置換次數(ACH)介於1~2次之間,顯示單靠現有空調來進行通風換氣無法提供良好的空氣品質。國內對於娛樂場所的通風換氣規定沒有明確的訂定,只有在建築技術規則中有提及關於酒吧場所所需之通風量,其他場所則無相關的規定,因此建議應訂定娛樂場所所需之通風換氣量,以改善網咖的室內空氣品質及確保消費者之健康。
The purpose of this study was to investigate the indoor air quality (IAQ) in Net-cafés by measuring bioaerosol and environmental parameter, and to propose the strategy of IAQ improvement. The single-stage and six-stage bioaerosol impactors, indoor air quality monitor, photoionization detectors, formaldehyde monitor and aerosol monitor were used to evaluate the indoor air quality of two Net-cafés in Tainan. The results were compared with Indoor Air Quality Standards of Taiwan (IAQST). The air change rate was also measured to study the efficacy of ventilation by using the spray of alcohol and photoionization detector. In addition, the difference of indoor air quality before and after a legislative ban on smoking in Net-cafés was evaluated in this study. The results shown that the concentration of CO2 in smoking area and non-smoking area exceed IAQST. The I/O ratio of fungi measurements were less than 1, but the I/O ratio of bacteria measurements were much greater than 1. Particle size distribution ranges of bacteria and fungi were 1.1~2.1m and 2.1~4.7 m, respectively. Most of the particulate matters were fine particles. After ban in smoking, the concentration of CO and particulate matters decreased (p <0.05), but the values were higher than the standard proposed by IAQST. Due to the increase of consumers, CO2 concentration also increased. Air change rate in Net-café was only about 1~2 ACH (air change per hour). Fresh air exchange rate by HVAC system is apparently insufficient to maintain comfortable indoor air quality. Based on these results, the efficiency of ventilation in Net-cafés needs to be regulated and improved for the IAQ and health of consumers.
