食米中重金屬（鎘、汞、鉛）含量調查
The Investigation on Heavy Metals (Cadmium, Mercury and Lead) in Rice
摘要
為瞭解臺灣地區生產之食米中重金屬（鎘•汞•鉛）含量之現況，於民國98年5月至10月間，由各縣市衛生局至其轄區，包括台北縣、桃園縣、新竹縣、基隆市、宜蘭縣、花蓮縣、台東縣、苗栗縣、台中縣、彰化縣、南投縣、雲林縣、嘉義縣（市）、台南縣、高雄縣、屏東縣等之碾米廠抽樣一、二期作之食米檢體，分別為77件及84件，共161件，由本局與衛生局（基隆市、南投縣、台南市及雲林縣）依據行政院衛生署公告方法執行檢驗。檢測結果，鎘含量總平均值為0.04 ppm（未檢出～0.37 ppm)，汞含量總平均值為0.002 ppm（未檢出～0.01 ppm），鉛含量總平均值為0.02 ppm（未檢出～0.16 ppm）。其中第一期作食米檢體，鎘之平均含量為0.04 ppm（未檢出～0.17 ppm)，汞之平均含量為0.002 ppm（未檢出～0.007 ppm)，鉛之平均含量為0.02 ppm（未檢出～0.16 ppm)；第二期作食米檢體，鎘之平均含量為O月4 ppm（未檢出～0.37 ppm)，汞之平均含量為0.001 ppm（未檢出～0.01 ppm），鉛之平均含量為0.02 ppm（未檢出～0.14 ppm）。161件食米檢驗之鎘、汞及鉛含量檢驗結果均未超出行政院衛生署公告之『食米重金屬限量標準』（鎘0.4 ppm、汞0.05 ppm及鉛0.2 ppm）。
並列摘要
In order to investigate the contents of heavy metals (cadmium, mercury and lead) in rice in Taiwan, rice samples from the rice millers were collected from March to October, 2009. Seventy-seven samples of the first crop rice and 84 samples of the second crop were analyzed. The results showed that the total average content of cadmium, mercury and lead in rice were 0.04 ppm (N.D.~0.37 ppm), 0.002 ppm (N.D.~0.01 ppm) and 0.02 ppm (N.D.~0.16 ppm), respectively. The average contents of cadmium, mercury and lead for the first crop rice were 0.04 ppm (N.D.~0.17 ppm), 0.002 ppm (N.D.~0.007 ppm) and 0.02 ppm (N.D.~0.16 ppm), respectively. The average contents of cadmium, mercury and lead for the second crop rice were 0.04 ppm (N.D.~0.37 ppm), 0.001 ppm (N.D.~0.01 ppm) and 0.02 ppm (N.D.~0.14 ppm), respectively. All rice samples have shown for good safety and under control. The contents of cadmium, mercury and lead in rice were all in compliance with the regulation set by the Department of Health, Executive Yuan.
