中文摘要 | 本研究藉由測定空氣中PM10和粒狀污染物中重金屬Pb、Zn及Mn等項的濃度數據, 初步瞭解三至六月教學期間, 大仁藥學專校校區內空氣品質現況:春季(三至五月) PM10 濃度日平均值約 108.9 (μ g/m �纂^, 其中約佔 37.5 %之日數其 PM10 濃度超過 125 (μ g/m �纂^限值,而六月下旬實測平均數值僅 25.5 (μ g/m �纂^,其原因可能是正值 學校期末考試結束前夕,校區內之學生人數顯著減少,教學活動已幾近停止,此一濃度數據 可當作校園空氣背景值;此外,Pb 和 Mn 之含量幾微。 以我國現行之空氣品質標準而言, 推論校區內空氣品質大致能符合需求。但是,三月間 Zn 濃度實測值為 13.00 ∼ 19.87 ( μ g/m �纂^,雖然我國現行之空氣品質標準並未規範其最低閾值, 若與同時期高雄市之楠 梓等六個測站數值比較,則有明顯偏高現象,是否為臨近地區之固定污染源、或是校園內垃 圾焚化之金屬薰煙所導致,仍待後續驗證。 |
英文摘要 | This study was conducted to investigate the air qualities in the campus area of the Ta-Jen Junior College of Pharmacy by measuring the concentration of PM10 and those of lead, zinc and manganese in the particulate phase. The results revealed that the daily mean value of PM10 was 108.9 (μ g/m �� ) in spring (March ∼ May) of 1996. However, nearly 37.5% of the days within the time period were with concentrations of PM10 above the national air quality standard, 125 ( μ g/m �� ). The PM10 values inspected at the end of June were down to 25.5 (μ g/m �� ) and could be presumed as the background value in the ambient air of the Ta-Jen area. Both lead and manganese concentrations in the particulate phase were very low or hardly to be detected. It could be speculated that the air qualities of the Ta-Jen area were not bad in most time when comparing with the national air quality standards. Unfortunately, the concentrations of zinc in the particles of the Ta-Jen area were remarkably higher than those values measured from the six air monitoring stations in Kao-Hsiung City, Taiwan, during the same time period. Although there is not any air quality regulation to specify the limit of zine species in the air in Taiwan, the air with ahigh concentration of zinc species would be a problem to the air quality. Further investigation is suggested to progress for finding out the pollution sources and to reduce the zinc concentration in the air. |
