Abstract
空氣中的生物氣膠無所不在,可能造成感染、過敏、毒性反應等健康危害,是相當重要的職業及環境衛生問題。然而由於生物氣膠種類複雜、無標準化採樣分析方法,各類職業場所或室內環境中的整體生物氣膠評估仍相當缺乏。因此,本研究蒐集彙整國際上現有個人生物氣膠採樣分析方法,針對四種效能較佳的個人採樣器及三種濾紙測試其採樣及分析效率,以評估監測重要生物氣膠(如細菌和真菌)暴露的最佳方法。此外,在具有高濃度生物氣膠暴露的職場進行個人採樣,以驗證其現場應用的適切性,並進行該職場員工的初步個人生物氣膠暴露評估。根據採樣分析結果發現,三種測試的濾紙Gelatin、PTFE以及PC (Polycarbonate)中,以PC濾紙的採集效率較高。在比較個人採樣器部份,三種使用濾紙的採樣器 (Button aerosol sampler、IOM inhalable dust sampler及Filter cassette sampler) 搭配PC濾紙,與NIOSH personal bioaerosol cyclone sampler進行室內外的並排採樣(不同採樣時間15分鐘、2小時、4小時、8小時各進行5次),分析結果發現真菌及細菌的整體採樣收集效率以Button aerosol sampler及IOM inhalable dust sampler最佳,NIOSH personal bioaerosol cyclone sampler次之。在高生物氣膠職場(養豬場)的個人暴露,一個完整班次的可培養真菌濃度為1471 CFU/m3 - 2871 CFU/m3、可培養細菌為9053 CFU/m3 - 54553 CFU/m3、真菌孢子為2461 spores/m3 - 7379 spores/m3、總細菌則為3.7×106 Cells/m3 - 1.0×107 Cells/m3。生物氣膠整體濃度在乾式打掃(簡單打掃豬舍)時較高,濕式打掃(洗豬舍)時較低。工作人員的真菌及細菌暴露量相當高,特別是細菌,因此在工作時應有適當防護以避免健康危害。本研究結果提供了適當的生物氣膠採樣分析方法,進行職場員工個人生物性暴露評估。此方法可用以建立職場生物氣膠的背景資料,以提供未來建立相關暴露建議值或法規標準之依據。
