維尔納法斯基于1922年首先指出钴在动物体內的存在,但是微量元素的生理作用那时依然沒有研究出来。維尔納法斯基于1940年第一次提出了微量元素的生物学作用問題。但鈷在动物有机体生活中所起的极其重要的作用,还是在近几年才有比較丰富的研究,科瓦里斯基在罗曼諾夫羊的工作上查明:在钴盐不足时所表現的特有征候(貧血,食慾消失等)可以用 Werner Fazs first pointed out the existence of cobalt in animals in 1922, but the physiological role of trace elements was still not studied at that time. Werner Fazs first proposed the biological role of trace elements in 1940. However, cobalt plays an extremely important role in the life of animal organisms, or has only been relatively abundant in recent years. Kovaresky’s work on the Romanovs found that: Special signs (anemia, loss of appetite, etc.) can be used
