食物是人的主要镉摄入源。镉的日摄入量因地理区域、饮食习惯和污染源而异。进食的食物量和类型可能对镉的摄入量有很大影响,例如蚝、肾脏和肝脏含镉就很高。作者于1987～1989年调查了古巴哈瓦邪市幼儿园儿童、高中生、大学生和年轻士兵的膳食镉摄入量。总膳食(早、中、晚餐)样品和各种食物样品采自加工这些膳食和食物的厨房,每周取样2次,为期6个月。用原子吸收分光光度法分析测定样品的镉含量,分析结果列予表1。从表1的结果来看,镉的平均摄入量低于丹麦、荑目,日本、荷兰、西班牙和波兰与表2中的其它国家的近似或高于这些国家。此次调查只在集体食堂采集了样品,被调查对象
Food is the main source of human cadmium intake. Daily intake of cadmium varies by geographical area, eating habits and sources of pollution. The amount and type of food you eat may have a significant impact on your intake of cadmium, such as oysters, kidneys and liver cadmium. The author investigated the dietary cadmium intake of children, high school students, college students and young soldiers in KwaZuy-e-kindergarten from 1987 to 1989. The total diet (breakfast, lunch and dinner) samples and various food samples are taken from the kitchen where these meals and foods are processed, sampled twice a week for six months. The content of cadmium in the sample was determined by atomic absorption spectrophotometry. The results of the analysis are listed in Table 1. From the results in Table 1, the average cadmium intake is lower than that of Denmark, Japan, the Netherlands, Spain and Poland and other countries in Table 2 at or above these countries. The survey only collected samples in the collective canteen, the surveyed
