微量元素的主要来源系通过食物经消化道进入体内,因此某地区食物中微量元素含量有直接影响该地人群的摄入量及贮存量。为了合理调配膳食,保证机体合理供给某些微量元素,我们于1986年采用原子吸收法对苏州郊区50余种常见食物作了铜、锌、锰、铁、镍含量的检测;样品除绿豆、黄豆、赤豆分别来自四川、东北、启东外,其余食物均来自苏州郊区。为了防止污染,凡能洗涤的食品均用自来水,蒸馏水,去离子水反复 The main source of trace elements through the food through the digestive tract into the body, so a region of food trace elements in the population has a direct impact on the population intake and storage. In order to rationally formulate the diet and ensure that the body supplies some trace elements reasonably, we detected the contents of copper, zinc, manganese, iron and nickel in more than 50 kinds of common foods in the suburbs of Suzhou by atomic absorption spectrometry in 1986; , Red beans were from Sichuan, northeast, Qidong, the rest of the food from the suburbs of Suzhou. In order to prevent pollution, all foods that can be washed with tap water, distilled water, deionized water repeatedly
