摘要


為瞭解臺灣地區生產之食米中重金屬(鎘、汞)含量之現況,衛生署擬定本調查計畫,並由臺灣省各縣市衛生局協助配合抽樣,於民國87年7月至88年6月間至各轄區(包括台北縣、桃園、苗栗、台中、彰化、雲林、嘉義、台南、高雄、屏東、花蓮等區)內,資本額達一千萬以上的碾米廠抽樣一二期作的食米檢體,檢體送至本局並依行政院衛生署公告方法進行分析檢驗。經檢驗91件食米檢體,鎘含量總平均值為0.04ppm個(N.D.~0.10ppm),汞含量總平均值為0.003ppm(N.D.~0.009ppm);第一期作食米44件檢體中,鎘之平均含量為0.04ppm(N.D.~0.10ppm),汞含量平均為0.004ppm(N.D.~0.009ppm);第二期作食米47件檢體中,鎘之平均含量為0.04ppm(N.D.~0.109ppm),汞含量平均為0.003ppm(N.D.~0.006ppm)。檢驗結果均未超出行政院衛生署所公告『食米重金屬限量標準』(鎘0.5ppm以下,汞0.05ppm以下)之規定。顯示臺灣地區食米所含重金屬鎘及汞含量尚低,當可祛除民眾對食米衛生安全之疑慮。

In order to understand the content of heavy metals (cadmium and mercury) in rice in Taiwan, the Department of Health collected samples offered by the rice mills from July 1998 to June 1999. Ninety-one rice samples, including first and second crop rice, were examined. The results showed that the total average content of cadmium of rice was 0.04ppm (N.D.~0.10ppm), and mercury was 0.003ppm (N.D.~0.009ppm). The average content of cadmium of 47 second crop rice samples was 0.04ppm (0.01~0.10ppm), and mercury was 0.003ppm (0.001~0.006ppm). In this investigation, the safety and sanitation for all rice indicated to be under good control. The contents of cadmium and mercury in rice were all below the regulatory limits in Taiwan area.
