摘要
分布特征和相关性分析表明皖南茶叶中的硒来源于石煤。皖南茶叶的较高硒含量平均值为0.4ug/g,硒浸出率低于30%,因此实际上补硒的价值不高。硒的来源警示石煤中的有害元素也可能转移到茶叶中。
Distribution characteristics and correlativity analysis of selenium in tea, soil and rock indicate that the source of selenium in tea from South Anhui is come from stone coal. The average value of selenium content for higher selenium tea is 0.4 ug/g, the leaching rate of selenium is lower than 30%, so in fact,the tea is valueless for supplementing selenium. In addition, the research on source of selenium gives us a warning that the harmful elements could also be transferred from stone coal to tea.
