Gold is very low in activity and is usually present in seawater and soil in the form of nanoparticle. Plants and animals absorb these golden nanoparticles and then enter the body along the food chain.
Therefore, there are about 2 milligrams of gold in the human body. If it is extracted, the value is about 0.5 to 0.6 yuan. Our body carefully adjusts the concentration of bioactive metals and removes excess metal through the skin and hair.
Small babies less than three months have higher levels of gold in their hair than adults, mainly from breast milk, often at concentrations up to twice the average concentration of the crust.
