在自然界存在的近百种元素中,有60余种已在机体內发現。可以根据它們在机体內含量的多少分为多量元素、微量元素和超微量元素话闶墙参锾鍍群可儆?毫克%的各种元素称之为微量元素。属于这一类的有銅、鋅、錳、锶、詁、碘和氟等多种元素。含量更少的只有几微克%或还要少即称之为超微量元素,如汞、金、鉛、鐳等。这些元素在机体內虽含量极微但对机体的生命活动却有着巨大的作用孀湃藗冎R的进展,微量元素对机体的重要意义已愈来愈被人們所重視。
More than 60 kinds of nearly one hundred kinds of elements existing in nature have been found in the body. According to their content in the body can be divided into many elements, trace elements and trace elements words 闶 wall parameters 锾 plating group can 儆?

Less content only a few micrograms% or even less known as ultra-trace elements, such as mercury, gold, lead, radium and so on.

The progress of trace elements, the importance of trace elements to the body, has drawn more and more attention.
