摘要：

Selenium is an essential nutrient trace element for human with established recommended dietary intake levels for different age groups. Low Se status has been reported to be a contributing factor in a number of deficiency diseases, of which the best doucumented is Keshan disease, a cardiomyopathy occurring in certain regions of China. By now,there are still new Keshan disease patients occuring in some area of China such as Zhangjiakou district. In order to assess and monitor the selenium nutrient status in human health, it is necessary to precisely quantify selenium in environment materials especially low Se level materials. This paper reports the analysis method on determination Se in low Se grain samples by continuous flow hydride generation atomic absorption spectrometry (HGAAS).
