吉林省水利科学研究院近年在长春市双阳区黑顶子水库、查干湖等多处水域进行水生态系统保护与修复等科研工作时，连连检测发现了微量元素硒含量较高的富硒鱼，每千克中硒含量均大于富硒食品标准，同时小于毒性标准。最高达0．6mg／kg，超过富硒鱼标准200％，最低也达到0．22mg
Jilin Province Institute of Hydraulic Research in recent years in Shuangyang District, Changchun, Heiminzi Reservoir, Chagan Lake and other water areas for ecosystem protection and restoration of aquatic ecosystems and other scientific research, the repeated detection found that the selenium content of selenium-rich fish , Selenium content per kg are greater than the selenium food standards, while less than the toxicity standard. Up to 0.6mg / kg, more than 200% of selenium-enriched fish standard, the lowest reached 0.22mg
