由於人們每日長時間於室內空間活動,且目前建築物皆採用密閉式之設計,因此室內空氣污染物容易累積造成室內空氣品質惡化進而影響人體健康。研究指出車廂內所測得之污染物濃度高於車廂外之濃度,因此污染物極可能蓄積於車廂內,進而提高車廂內駕駛與乘客之暴露程度,若在交通尖峰時段車輛緩慢移動時將會更加嚴重。 本研究針對地下停車場及國道客運車廂現場進行PM10、PM2.5、粒徑分佈、BTEX(苯、甲苯、乙苯、二甲苯)、TVOC、甲醛、一氧化碳、二氧化碳之調查。客運車輛方面以往返台南與台北兩地之三家國道客運為對象,量測時間自上車開始至抵達目的地為止,車程約四至六小時。地下停車場方面以台南市兩家百貨公司與航空站為對象,量測時間由早上九點至晚上十點。 監測結果:客運方面,客運車廂內市區道路懸浮微粒濃度比高速公路時略高,除去二氧化碳(CO2)以外,懸浮微粒(PM)、一氧化碳(CO)、甲醛(HCOH)皆符合台灣、香港與WHO之建議值。 地下停車場方面,懸浮微粒濃度接近出入口之濃度比停車場中心點要高,懸浮微粒濃度在開店之前濃度較高,而氣狀污染物濃度則較低,開店之後因為通風系統的開啟懸浮微粒濃度開始下降但氣狀污染物濃度則應位車輛逐漸增加而開始增加。甲醛(HCOH)之濃度有出現高於台灣建議值的現象而懸浮微粒(PM)、二氧化碳(CO2)而一氧化碳(CO)、TVOC之濃度皆符合台灣建議值。
People long hours every day activities in the indoor space, buildings are currently designed using closed. Therefore, accumulation of pollutants in indoor air, resulting in deterioration of indoor air quality affect human health. Pollutants likely to accumulate in the cabin, raise the car driver and passenger cabin of exposure. If traffic is slow moving rush hour traffic will be more serious. In this study, long-distance buses, underground parking and PM10, PM2.5, particle size distribution, BTEX (benzene, toluene, ethylbenzene, xylene), TVOC, formaldehyde, carbon monoxide, carbon dioxide investigation.Long-distance buses to Taipei from Tainan and three long-distance bus companies as the target. Measurement time on the bus began to arrive at the destination stop, the journey takes about 4-6 hours.Underground parking to two department stores and an airport in Tainan City for the object, measuring time from 9:00 to 22:00 am. Monitoring Results: The long-distance buses, in addition to carbon dioxide (CO2) than, suspended particulate (PM), carbon monoxide (CO), formaldehyde (HCOH) are in compliance with Taiwan, Hong Kong and WHO recommended value of. Underground parking, formaldehyde (HCOH) higher than the concentration recommended values in Taiwan, and suspended particulate (PM), carbon dioxide (CO2) and carbon monoxide (CO), TVOC concentrations are in compliance with recommended values in Taiwan.
