利用室內植物減低醫療院所密閉空間空氣污染物監測評估及宣導推廣專案工作計畫
| 中文摘要 | 本計畫蒐集彙整醫療院所內各空間空氣污染物相關資訊，並實際測量植物改善空氣品質之能力。於台北市某教學級醫院公共空間，包括醫護人員工作區、病房區家屬休息區、醫院大廳掛號區及領藥區等四處進行二氧化碳、甲醛及懸浮微粒濃度取樣及數據分析；於春、夏、秋三季各進行一次。結果顯示醫院室內二氧化碳濃度以醫護人員工作區濃度較低，並四場所二氧化碳濃度受季節影響，以秋季濃度較高，四場所平均測值皆超過環保署公告之醫院等第一類場所建議值600 ppm。醫護人員工作區及病房家屬休息區之甲醛濃度較高，然四場所平均測值皆未超過環保署公告之醫院等第一類場所建議值0.1 ppm。醫院大廳之懸浮微粒濃度較高，尤以掛號區較領藥區高，但四場所平均測值皆未超過環保署公告之醫院等第一類場所建議值。 於擺放植物前一周及放置當周連續測量前述四場所之空氣品質。綜合三季節結果顯示於醫療院所擺放植物降低環境二氧化碳及甲醛濃度之效果有限，但可降低平均總懸浮微粒濃度，及些微降低平均PM2.5及PM10濃度。 利用儀器實際測量25種室內植物放置於前述四場所中當日及一星期後之光合作用參數。結果顯示除醫院大廳領藥區外，25種室內植物於其餘三場所擺放當日及一周後之淨光合作用速率皆偏低或為負值。在四場所仍可維持較高淨光合作用值之植物種類為袖珍椰子及常春藤，於光線較不足場所仍可維持較高淨光合作用值之植物種類為粗肋草‘銀后’及黃金葛。臺灣原生植物中以羅漢松及竹柏有較佳表現，但建議放置於明亮處才能有較佳淨化空氣效能。根據試驗結果建立醫療院所中不同場所植栽選擇、配置資料庫及示範。於101年8月9日、8月16日及8月23日三天，辦理「種子教師」研習，推廣環境綠化以期提升市民生活品質。三場研習會學員人數分別為65、72及60人，皆踴躍參與課程，積極提問，課後測驗僅7人未通過。研習會成員中社區管委會及鄰里長辦公室人員佔53%，一般民眾佔35%，其餘分別為社區大學或環保綠化相關單位成員。 | ||

Reduce air pollutants of interior places in the hospital by using indoor plants
| 英文摘要 | The aim of the project was to study the air pollutants in four locations of a hospital building, and the ability of the plant species to reduce air pollutants. Carbon dioxide (CO2), formaldehyde, particulate matter (PM) concentrations were monitored at medical working area, family salon, register area, and pharmacy. Each location were monitored for seasonal effect (spring, summer and autumn). Results showed that CO2 concentration was lower at the medical working area compared to other locations. All locations had higher CO2 concentrations in autumn. Throughout monitoring period, average CO2 concentrations exceed 600 ppm as recommended by EPA. Medical working area and family salon had higher formaldehyde concentrations than the other two locations. Neither locations exceed 0.1 ppm formaldehyde as recommended by EPA. Hospital lobby had higher PM concentrations than the other two locations, especially at register area. Neither locations exceed PM concentration as recommended by EPA. Plant installation had little effect on CO2 and formaldehyde concentrations of the four locations tested. However, plant installation did reduce total suspended particulate matter concentrations, and slightly reduce PM2.5 and PM10 concentrations. Twenty-five indoor plant species, including six Taiwan-native species, were placed in the hospital areas. Results showed that, except at pharmacy, many plant species had low or negative net photosynthetic rate on day 7 after placing in the hospital areas. Recommended plant species for all four locations were parlour palm (Chamaedorea elegans) and English ivy (Hedera helix). Plants with higher net photosynthetic rates under low light conditions were Aglaonema ‘Silver Queen’ and golden pothos (Epipremnum aureum). Among Taiwan-native plant species tested, Podocarpus macrophyllus and Nageia nagi had better performance, but the plants should be placed at brighter sites. Three tutor conferences were held on Aug 9th, 16th, and 23rd for promoting community greening. | ||
