对以稻谷为主食的国家来说,镉摄入的主要来源是稻。在印度尼西亚,镉日摄入量中约50%来自稻谷,日本约为40～60%。稻谷中的镉来自土壤,通过稻的根部吸收。因此,稻谷可能是监测环境镉的最好样品。全世界稻谷主要生产国为印度、中国、孟加拉国、泰国、印度尼西亚、菲律宾、日本、朝鲜、巴西、马来西亚和新加坡。本研究旨在确定上述国家稻谷中的镉含量,并根据测定数据,计算出每日从 For countries where rice is the staple food, the main source of cadmium intake is rice. In Indonesia, about 50% of the daily intake of cadmium comes from rice, while Japan is about 40-60%. Cadmium from the soil from the soil, through the roots of rice absorption. Therefore, paddy may be the best sample for monitoring environmental cadmium. The main rice producing countries in the world are India, China, Bangladesh, Thailand, Indonesia, the Philippines, Japan, North Korea, Brazil, Malaysia and Singapore. The purpose of this study was to determine the cadmium content of rice in the above countries and to calculate the daily
