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99年4至10月間，由各縣市衛生局至其轄區，包括桃園縣、新竹縣、宜蘭縣、花蓮縣、台東縣、苗栗縣、台中縣、彰化縣、南投縣、雲林縣、嘉義市（縣）、台南縣、高雄縣及屏東縣等碾米廠抽樣一、二期作之食米檢體，分別為76及85件，共計161件，由本局與協力衛生局（基隆市、南投縣、台南市）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0.04ppm（未檢出-0.18ppm），汞含量總平均值為0.004ppm（未檢出-0.013ppm），鉛含量總平均值為0.02ppm（未檢出-0.09ppm）。其中第一期作食米檢體，鎘之平均含量為0.04ppm（0.01-0.13ppm），汞之平均含量為0.004ppm（未檢出-0.013ppm），鉛之平均含量為0.02ppm（未檢出-0.09ppm）；第二期作食米檢體，鎘之平均含量為0.04ppm（未檢出-0.18ppm），汞之平均含量為0.005ppm（未檢出-0.013ppm），鉛之平均含量為0.02ppm（未檢出-0.07ppm）。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0.4ppm、汞0.05ppm及鉛0.2ppm）。

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 April to October, 2010. Seventy-six samples of the first crop rice and 85 samples of the second crop were analyzed. The results showed that the total average contents of cadmium, mercury and lead in rice were 0.04 ppm (N.D.-0.18 ppm), 0.004 ppm (N.D.-0.013 ppm) and 0.02 ppm (N.D.-0.09 ppm), respectively. The average contents of cadmium, mercury and lead for the first crop rice were 0.04 ppm (0.01-0.13 ppm), 0.004 ppm (N.D.- 0.013 ppm) and 0.02 ppm (N.D.-0.09 ppm), respectively. The average contents of cadmium, mercury and lead for the second crop rice were 0.04 ppm (N.D.-0.18 ppm), 0.005 ppm (N.D.-0.013 ppm) and 0.02 ppm (N.D.-0.07 ppm), respectively. All rice samples have shown good safety and are 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.
