摘要

為了解鉛相關工業對附近環境空氣的影響，本研究選擇一廢蓄電池回收工廠之半徑五百公尺範圍為研究對象，在距離工廠不同方位和距離放置七部空氣採樣器，作連續24小時之採樣。並在距離工廠最近採樣點放置三部採樣器，作日、夜和24小時之工廠工作日和休假日之採樣，共得樣本80個，結果如下：
(1)整個研究區之空氣鉛濃度平均值為1.42±1.55μg/立方公尺，懸浮微粒含鉛量為11,640±11,650μg/g，大部分採樣點之濃度，隨著距離工廠愈遠，污染濃度逐漸下降。
(2)在距離工廠56公尺之採樣點，工廠運轉時間內，日、夜之空氣鉛濃度相近，八個採樣天中，有四天其夜間濃度高於白天濃度。其全日平均達7.58μg/立方公尺，是工廠休息時之26倍，工廠休息時之日、夜濃度分別是0.57μg/立方公尺及0.22μg/立方公尺，全日平均為0.28μg/立方公尺。
本研究顯示該鉛工廠對附速環境空氣為全天性污染型，已造成該地區嚴重之空氣污染。

To determine the air concentration of lead in the vicinity of a lead recycling factory, we conducted this study by collecting total suspended particulates with Kimoto high volume air sampler and analyzed by atomic absorption spectrometry with a Hitachi 180/70 instrument. The results showed as follows:
The lead concentration in the area studied was 1.42±1.55 μg/m^3. The lead content in the suspended particulates was found to be 11,640±11,650 μg/g. The lead level in the air decreased by the distance away from the factory.
In average, the lead concentration at night was as high as that in the day time. However, for half of the sampling days, the lead level at night was higher than that of the day time. The average lead concentration for the working day was 7.58 μg/m^3, 26 times that for the holiday.
