| 中文摘要 | 台灣是海島國家,漁獲取得容易。為了解國民所攝食之魚肉是否遭受污染,本研究針對市售海洋魚類100件檢體,分析其中重金屬鎘(Cd)、鉻(Cr)、銅(Cu)、鎳(Ni)、鉛(Pb)、錫(Sn)、鋅(Zn)及汞(Hg)之含量。另外為同時分析多種元素,縮短分析時間並能精確檢測微量的重金屬含量,本研究建立濕式消化法之樣品前處理,並配合石墨爐式原子吸收光譜儀及火燄式原子吸收光譜儀同時檢測七種重金屬之含量;汞則以微波消化法配合汞原子螢光光譜儀分析。經取魚肉、魚肝及貽貝粉等標準參考物質(certified reference materials) 適量,以硝酸5 mL濕式消化分解完全後,定容至10 mL分析定量;並另取適量標準參考物質以微波消化法分析汞元素,三重複結果都能符合標示值。將方法應用於各魚市、傳統市場及超級市場所抽購之100件魚類檢體,包括白帶魚,嘉臘,秋刀魚,白鯧,青衣,旗魚,鮪魚,鯊魚,鮭魚,鱈魚等10類魚種各7件,及其他魚類30件,結果鎘含量總平均值為0.007 μg/g (N.D. ~ 0.067 μg/g)、鉻含量總平均值為0.011 μg/g (N.D. ~ 0.082 μg/g);銅含量總平均值為0.270 μg/g (N.D. ~ 1.954 μg/g);鎳含量總平均值為0.022 μg/g (N.D. ~ 0.112 μg/g);鉛含量總平均值為0.016 μg/g (N.D. ~ 0.087 μg/g);錫含量總平均值為0.019 μg/g (N.D. ~ 0.330 μg/g);鋅含量總平均值為2.909 μg/g (1.097 ~ 6.366 μg/g);汞含量總平均值為0.188 μg/g (0.001 ~ 1.515 μg/g)。 |
| 英文摘要 | In order to analyze heavy metals in fish samples, a simple and rapid wet digestion method was developed for complete destruction of the marine fish tissue samples, as opposed to the conventional dry-ashing procedures. An atomic absorption spectrometer equipped with Zeeman background correction was used for the determination of heavy metals of Cd, Cr, Cu, Ni, Pb, and Sn. Zn was analyzed by a flame atomic absorption spectrometer. Hg was determined by a mercury atomic fluorescence spectrometer after the microwave digestion pretreatment. The method was evaluated using certified reference materials. The developed method was applied to analyze 100 marine fish samples, including hairtail, porgy, Pacific saury, pomfret, parrotfish, swordfish, tuna, shark, salmon, cod, and other specimens. The results showed that average content of Cd, Cr, Cu, Ni, Pb, Sn, Zn, and Hg was 0.007 mg/g (N.D.~0.067 mg/g), 0.011 mg/g (N.D.~0.082 mg/g), 0.270 mg/g (N.D.~1.954 mg/g), 0.022 mg/g (N.D.~0.112 mg/g), 0.016 mg/g (N.D~0.087 mg/g), 0.019 mg/g (N.D.~0.330 mg/g), 2.909 mg/g (1.097~6.366 mg/g), and 0.188 mg/g (0.001~1.515 mg/g) , respectively. |
