Urine beryllium

There are more than 30 elements in nature, and more than 60 can be detected by the human body. Among them, there are 11 kinds of macroelements necessary for human body, and there are more than 50 kinds of trace elements less than 0.1% of body weight. There are currently 14 types of essential trace elements known to the human body, but they do not contain urinary beryllium. Therefore, the study of trace elements has become one of the important foundations of cutting-edge sciences such as biogeochemistry, inorganic biochemistry, molecular biology, and origin of life.
