中文摘要	本計畫研究對象為戴奧辛及重金屬，主要工作內容包括：排放清冊更新，排放檢測及環境監測、法規檢討與研訂及提供行政與技術支援；針對各項工作成果說明如下：戴奧辛部份，推估94年度戴奧辛排放總量為101.9 g I-TEQ/年，較93年度減少42.1 g I-TEQ/年，減少29%；最大污染源仍為台灣鋼聯公司。「煉鋼業集塵灰高溫冶煉設施戴奧辛管制及排放標準」於94年10月12日發布實施，95年度稽查結果顯示戴奧辛排放濃度皆符合排放標準；預期國內戴奧辛排放量將會持續下降。總計完成全國62站次、兩次環境空氣戴奧辛監測工作(分別於95年8月至95年10月、95年12月至96年1月)，監測結果戴奧辛平均濃度分別為0.032 pg I-TEQ/m3及0.043 pg I-TEQ/m3(不含國家公園測站)，環境空氣戴奧辛濃度以中部空品區及高屏空品區較高；國家公園測站濃度最低。由於國內戴奧辛排放量持續下降，環境空氣戴奧辛濃度與91、92年度調查數據相較(平均值0.089 pg I-TEQ/m3)，也已經明顯降低許多。排放稽查部份，共完成燃煤電廠、電弧爐、焚化爐及台灣鋼聯公司等五座次污染源戴奧辛排放稽查檢測，稽查結果皆可符合排放標準值。重金屬部份，推估94年度各類別重金屬排放量發現，.鉛排放量為24.3噸/年；最大排放源為二級鉛冶煉製程，排放量為8.93噸/年。其他業別依據實際檢測數據推估發現，主要排放源為燃煤發電、燃煤汽電共生鍋爐、電弧爐和水泥窯。鎘排放量為0.946噸/年；燃煤發電鍋爐和燃煤汽電共生鍋爐是主要排放源，其次是水泥窯和電弧爐。汞排放量約為1.36噸/年；以水泥窯及垃圾焚化爐為主，各佔26.0%及20.0%，其次是電弧爐、燃煤發電鍋爐。砷排放量約為5.64噸/年；燃煤發電及燃煤汽電共生鍋爐為主要排放源，其次是水泥窯。研擬「半導體及光電業重金屬砷排放及管制規範」部份，以風險評估為基準，推估最大容許排放濃度並考量控制技術可行，建議砷排放標準為0.0015 mg/Nm3；檢討「固定污染源重金屬排放標準」部份，建議各類別重金屬排放標準分別為鉛及其化合物1.5 mg/Nm3、鎘及其化合物0.6 mg/Nm3、汞及其化合物1.6 mg/Nm3，及砷及其化合物重金屬排放標準值為0.1 mg/Nm3。
