However, under the socialist system in our country, the party and the state have always been concerned about the health of the people, resolutely implementing the principle of “prevention first” and the directives on environmental protection and are vigorously strengthening their environmental monitoring work.

Therefore, analyzing the mercury content in the hair is very important for understanding the degree of mercury pollution in the human body. Of course, the amount of mercury in the hair reflects only the past mercury load in the body. Analysis of the hair content of mercury, can reflect different
