1817年,瑞典化学家柏采利乌斯在研究硫酸厂铅室中沉淀的红色淤泥的性质时,发现了一种性质与碲相似的新元素。柏采利乌斯将这种新发现的元素命名为硒(Se)。在随后的一百多年里,人们发现这种在地壳中含量极微的稀有元素对人体有很重要的作用,它既是人体不可或缺的微量元素,但摄入过量也会引起中毒。这种让人“又爱又恨”的元素,到底与我们的身体有什么样的关系呢?
In 1817, the Swedish chemist Paceylius discovered a new element similar in properties to tellurium when investigating the nature of red mud that precipitated in the lead-acid chamber of a sulfuric acid plant. Perseus named the newly discovered element selenium (Se). In the following hundred years, it was discovered that this rare element in the earth’s crust is very important to the human body. It is not only an essential trace element for the human body, but it can cause poisoning if it is taken in excess. This kind of people “love and hate ” elements, in the end with our body what kind of relationship?
