Regional Distribution of Dioxin/Dioxin-like PCBs in Foodstuffs around Taiwan

為瞭解我國食品中戴奧辛及戴奧辛類多氯聯苯背景值分布情形，依據行政院環境保護署空氣品質監測區，將全台灣劃分為八大地區，於102－108年度分年執行各地區食品中戴奧辛及戴奧辛類多氯聯苯背景值含量調查。綜整102－108年822件食品中戴奧辛含量調查結果，各類食品戴奧辛毒性當量平均濃度（pg WHO05-TEQ wet weight）（範圍，件數）分別為：全穀雜糧類0.017（0.002－0.05，66件）、乾豆堅果類0.012（0.002－0.07，23件）、油脂類0.063（0.01－0.189，24件）、家禽類及其製品類0.040（0.007－0.181，47件）、家畜類及其製品類0.032（0.003－0.265，87件）、魚水產類0.268（0.005－2.32，175件）、蛋類0.057（0.011－0.202，32件）、乳品類0.024（0.002－0.117，57件）、水果類0.004（0.001－0.027，58件）、蔬菜類0.010（0.0005－0.233，98件）、糖及糖果零食類0.017（0.007－0.024，8件）、飲料類0.005（0.003－0.006，5件）、調味料類0.025（0.002－0.245，29件）及複合食品、湯品及其他類0.020（0.004－0.12，113件）。除103年及106年各發現1件鴨肉及1件雞蛋樣本之戴奧辛／呋喃（Polychlorodibenzo-p-dioxins and dibenzofurans／Furans, PCDD／Fs）超出我國規範之限值，其餘上述各類食品皆符合我國「食品含戴奧辛及戴奧辛類多氯聯苯處理規範」食品中戴奧辛及戴奧辛類多氯聯苯含量總和之限值。

During 2013-2019, the background levels of PCDD/Fs and DL-PCBs in selected foods in the air quality regions (AQRs), including North AQR (Taipei, New Taipei, Taoyuan City), Chu-Miao AQR(Hsinchu and Miaoli Country), Central AQR (Taichung, Changhua, and Nantou City), Yun-ChiaNan AQR (Yunlin, Chiayi, and Tainan City), Kao-Ping AQR (Kaohsiung and Pingtung County), HuaTung AQR (Hualien and Taitung City), YiLan AQR (Yilan County) and Offshore Islands AQR (Kinmen, Penghu, Lianjiang County) had been monitored respectively. A total of 822 food samples were collected for PCDD/Fs and DL-PCBs levels monitoring from 2013 to 2019. Based on per gram of wet weight, PCDD/Fs/DL-PCBs levels (pg WHO05-TEQ wet weight) of all kinds of food samples were as follows, cereals: 0.017 (0.002-0.05, N=66), nuts and beans: 0.012 (0.002-0.07, N=23), fats and oils: 0.063 (0.01- 0.189, N=24), poultry products: 0.040 (0.007-0.181, N=47), livestock products: 0.032 (0.003-0.265, N=87), fish and seafood: 0.268 (0.005-2.32, N=175), eggs: 0.057 (0.011-0.202, N=32), milk: 0.024 (0.002-0.117, N=57), fruits: 0.004 (0.001-0.027, N=58), vegetable: 0.010 (0.0005-0.233, N=98), candy: 0.017 (0.007-0.024, N=8), drinks: 0.005 (0.003-0.006, N=5), seasoning: 0.025 (0.002-0.245, N=29) and complex /others: 0.020 (0.004-0.12, N=113). Only one duck meat and one chicken egg were substandard in 2014 and 2017, respectively. All of the other 820 food samples were below the maximum residue levels (MRLs) of PCDD/Fs/DL-PCBs announced by Taiwan Food and Drug Administration.
