【摘要】 <正> 十多年来,国内外对辐照食品进行了大量的工艺条件和卫生安全性的研究。系统地收集和评述辐照食品作为人类食品时,对人体健康有否影响的资料是辐照保鲜技术推广应用的一个极重要的工作。本工作在文献[1]、[2]的基础上,开展了人群摄食辐照食品卫生安全性评价研究,叙述了血清中微量元素分析法和研究结果,为辐照食品卫生安全性提供了依据。更多还原

【Abstract】 A method of trace element analysis by ICP-AES in serum from human eating food preserved by irradiation is described. Trace element analysis in human serum is one of the research projects concerning the wholesomeness78 serum samples of the human eating food preserved by irradiation were collected. After ashing and solving ICP-AES analysis of serum is performed for detection of 12 trace elements in specimen solution. The detection limitations are in the range of 10-2-10-3 ppm for different elements. The recoveries of elements are over 73%.Concentrations of 12 trace elements in 78 human serum has been calculated with F and t tests at PDF 11/70 computer and it was concluded that there is no significant difference between testing group and control group更多还原
