中文摘要 | 監測417件米樣品及的件貝類樣品中砷、鎘、鉻、銅、汞、鎳、鉛及鋅八種重金屬含量,米樣中砷、鎘、鉻、鋼、汞、鎳、鉛及鋅平均含量分別為0.08、0.01、0.10、2.22、0.001、0.29、0.01及14.7mg/kg;米樣中八種重金屬平均含量皆較國外者低;所有米樣中鎘及汞含量皆未超過食米衛生標準 (鎘為0.5mg/kg ,汞為0.05mg/kg) 。貝類樣品中砷、鎘、鉻、銅、汞、鎳、鉛及鋅平均含量分別為1.55、0.15、0.18、13.1、0.004、0.37、0.17及50.3 mg/kg;牡蠣中銅及鋅含量顯著高於二枚貝中之銅及鋅含量;貝類中重金屬平均含量皆未超過香港及丹麥、英國、德國等國之管制標準。依據上述資料經由國人對車類及貝介類之取食量,推算國人經由取食米類及貝類而攝入之重金屬量,結果顯示八種重金屬之攝取量皆低於WHO/FAO及USNAS所推薦之法定每人每過可容許攝取量 (Provisional Tolerable Weekly Intake,PTWI) 。 |
英文摘要 | This investigation surveyed heavy metal content of Taiwanese rice and shellfish. A total of 407 rice samples and 83 shellfish samples were collected from various areas of Taiwan. The content of As, Cd, Cr, Cu, Hg, Ni, Pb and Zn in the rice samples was 0.08, 0.01, 0.10, 2.22, 0.001, 0.29, 0.01 and 14.7 mg/kg, respectively. Notably, the Cd and Hg content in the rice samples was found to be below the food sanitary standards of Cd (0.5 mg/kg) and Hg (0.05 mg/kg) in Taiwanese rice. On the other hand, the As, Cd, Cr, Cu, Hg, Ni, Pb and Zn content in shellfish was 1.55, 0.15, 0.18, 13.1, 0.004, 0.37, 0.17 and 50.3 mg/kg, respectively. Notably, oysters had higher content of Cu and Zn than mussels. The average content of heavy metals in Taiwanese shellfish was always below the limits or standards of the UK, Denmark and Germany. To assess the safety of dietary intake, weekly intake of heavy metals by rice and shellfish was calculated based on the intake of a typical Taiwanese. The results indicated that weekly intake of heavy metals from rice and shellfish was below the provisional tolerable weekly intakes recommended by WHO/FAO and USNAS. |
