Grain, flour and milk samples were collected in spring 1980 and analysed for selenium. The selenium content of flour was approximately 10 times higher than in 1975-1977, and that of milk twice as high. The increase in the selenium content of flour is a reflection of the massive grain imports in 1979/80. The increased selenium level in milk was more unexpected, and may at least partly be due to the increased use of fodders enriched with selenium. The average intake of selenium in 1980 may have been between 50 and 60 micrograms/d/person, while the mid seventies it was found to be substantially lower, about 30 microns/d.
1980年春季采集了谷物、面粉和牛奶样本并分析其中的硒含量。面粉中的硒含量比1975 - 1977年高出约10倍，牛奶中的硒含量则高出两倍。面粉中硒含量的增加反映了1979/80年大量的谷物进口。牛奶中硒水平的升高则较为意外，这可能至少部分归因于富含硒的饲料使用增加。1980年硒的平均摄入量可能在每人每天50至60微克之间，而在七十年代中期发现其摄入量要低得多，约为每天30微克。
