摘要

本研究以屏東縣長治鄉之一汽車資源回收場為對象，探討大氣中以及作業環境中多環芳香烴化合物之暴露研究。在資源回收廠中採樣點共計4處：包括　A.辦公行政區、B.細部拆解區、C.廢油回收區、D.道路區，於前述四處進行採樣，以個人階梯衝擊式採樣器(Personal Cascade Impactor, Marple) 、個人採樣衝擊器(PM2.5與PM10)上鐵氟龍濾紙以及石英濾紙流量固定在3 ml/min（上午9:00~下午6:00）進行連續四天採樣，大氣部分則以高量採樣器(PS1)參考環檢所 NIEA A102.12A高量採樣法進行總懸浮微粒(TSP)之採樣，並紀錄現場環境因子（溫度、濕度、照度、風速、大氣壓力）採樣結束並進行乾濕調理及秤重後，參考環檢所 NIEA M165.00C 方法進行索氏萃取實驗，並將實驗後樣品以GC/MS並進行PAHs分析。
實驗結果顯示: (1)汽車資源回收廠大氣中平均總懸浮微粒濃度為133.43 μg/m3。 (2)汽車資源回收廠作業環境中懸浮微粒質量濃度平均範圍介於57.75~144.2 μg/m3。 (3)汽車資源回收廠作業環境中以Marple以粒徑(PM14.8~21.3)為最高峰值。(4)汽車資源回收廠作業環境中 PAHs濃度範圍介於1802.1~6606.8 ng/m3。其中最高濃度PAHs採樣點為道路區為主，在汽車資源回收廠中以低分子量(2、3環)PAHs為主。(5)汽車資源回收廠中PAHs暴露量已採樣點細部拆解區為最高19820.41 ng/d。

This study investigated the exposure of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere and the working areas of an automotive dismantler yard in Changjhih Township, Pingtung County, Taiwan. Sampling was administered at four spots in the yard: (a) the office area, (b) dismantling site, (c) waste oil recycling area, and (d) road area. For these four sampling spots, Teflon and quartz filter papers were attached to a personal cascade impactor (Marple) and personal sampling impactor (PM2.5 and PM10) set at a fixed flow of 3 mL/min to collect specimens for 4 consecutive days (9:00 a.m.–6:00 p.m.). For the atmosphere, a high volume sampler (PS1) was used to sample the total suspended particulates (TSP) by employing the NIEA A102.12A high-volume sampling technique established by the Environment Analysis Laboratory of Taiwan. Environmental factors (e.g., temperature, humidity, illuminance, wind velocity, and atmospheric pressure) were recorded on site. After the humidity of the sampled specimens was controlled and the specimens weighed, the specimens were tested in a Soxhlet extraction experiment by using the NIEA M165.00C technique. Finally, the PAHs were analyzed using gas chromatography–mass spectrometry.
The results showed that (a) the average TSP in the automotive dismantler yard was 133.43 μg/m3. (b) The average mass concentration of the TSP in the working areas of the dismantler yard ranged from 57.75 to 144.2 μg/m3 (c) The Marple in the working areas has a peak value at a particle size of PM14.8–21.3, and (d) the PAHs in the working areas ranged between 1802.1 and 6606.8 ng/m3. Among the four sampling spots investigated, the road area has the highest concentrations of PAHs, whereas most of the working area was dominated by low-molecular-weight PAHs (2- and 3-ring). (e) In the automotive dismantler yard, PAH exposure was the highest at the dismantling site, at 19820.41 ng/d.
