| 目的 获得我国当前食物中元素浓度和成年男子膳食摄入量,为参考人元素摄入量参数提供依据和进行有关卫生学评价。方法 以总膳食研究混合食物样品法,用NAA、ICP-MS、ICP-AES、AAS等技术和必要QA措施测定我国4个不同膳食类型地区膳食的各类食物中元素浓度,估算日摄入量和卫生学评价,并将所获摄入量与有关国际资料进行比较。结果 获得了我国12类食物中42种元素浓度和成年男子摄入量及其卫生学评价。结论 更新和拓展了我国食物中元素浓度和摄入量国情资料,为我国参考人摄入量参数确定提供新依据,揭示了当前我国卫生问题,如从营养卫生角度,我国参考人Ca、Zn和Cu摄入量偏低,而从食品卫生而言,Pb、Cd、Mn和Na摄入量过高,尤其是近年Pb、Cd和Hg摄入量升高,Pb和Cd平均摄入量已超过ADI,应引起重视。 |

| Objective To obtain concentrations of elements in Chinese current foods and their dietary intakes by adult man in order to provide a basis on intake parameters of Chinese Reference Man and make related hygienic evaluation. Methods With mixed food sample method of total diet study, determination of element concentrations in constitent foods of diets for 4 areas with different diet types was carried out by using NAA, ICP-MS, ICP-AES, AAS and necessary QA measures, and estimation of their daily intakes and hygienic evaluation were also made. Results The concentrations of 42 elements in 12 categories of foods, their intakes and hygienic evaluation for adult man were obtained. Conclusion The data on element concentrations in Chinese foods and their dietary intakes were updated and widened.These data provided a new basis for developing the parameters of Chinese Reference Man and revealed some current hygienic problems.For example, from viewpoint of nutrition hygiene the Ca, Zn, and Cu intakes for Chinese Reference Man are insufficient, and from consideration of food hygiene the intakes of Pb, Cd and Na are excessive..Especially, the and Cd average daily intakes of Pb, Cd and Hg have been increased during recent years, those of Pb exceed their ADIs, which should be paid attention to. |
