摘 要

利用泡綿(Polyurethane Foam)當做慣性衝擊器收集板時的收集效率較為平緩的原理，本研究設計了一個個人粉塵採樣器，並於實驗室進行校正測試，且於工作場所與其他採樣器進行粉塵濃度比對測試。本採樣器含可吸入性粉塵入口，截取氣動直徑10μm的胸腔區慣性衝擊器，截取氣動直徑4μm的可呼吸性慣性衝擊器。本研究在實驗室進行微粒的收集效率實驗，結果顯示本採樣器採樣流量為3.2 L/min，使用100ppi泡綿為衝擊板時在一倍的噴嘴板—收集板距離(jet-to-plate distance)下，可以符合ISO/CEN/ACGIH的胸腔區及可呼吸性粉塵採樣效率規範，胸腔區粉塵慣性衝擊器和可呼吸性粉塵慣性衝擊器的截取氣動直徑分別為9.6μm�n 及4μm。研究亦發現固體微粒收集效率曲線與液體微粒收集效率曲線十分吻合，證明本研究所使用之泡綿收集板具有抑制固體微粒彈跳的問題。

本研究於A(鉛粉廠球磨機)、B(鉛蓄電池切板區)、C(鑄鐵廠澆鑄區)三個不同工作場所中同時利用個人粉塵採樣器、IOSH 旋風器、Marple個人採樣器和Respicon採樣器進行可吸入性粉塵、胸腔區粉塵和可呼吸性粉塵濃度的比對測試。由現場採樣比對結果可知，在可吸入粉塵方面，A、B、C三個廠的新型採樣器和Respicon採樣器的粉塵濃度均無顯著差異。在胸腔區粉塵方面， A廠和C廠的新型採樣器和Respicon採樣器的粉塵濃度有明顯的測值差異。可呼吸性粉塵方面，C廠的新型採樣器和Respicon採樣器的粉塵濃度有明顯的測值差異。

關鍵詞：個人粉塵採樣器、慣性衝擊器、胸腔區粉塵、可呼吸性粉塵、氣膠採樣
