Are all the heavy metals that the human body can't bear toxic?

When it comes to heavy metals, everyone will think of heavy metal poisoning. We often hear about lead poisoning, mercury poisoning and so on. Are heavy metals themselves toxic? That's not the answer. A very small amount of heavy metals is not toxic, but excessive heavy metals can cause poisoning to animals, plants and humans.

This is because excessive heavy metals can react with protein in human body after entering human body. Leading to protein degeneration of human body. Then lose biological activity, and finally cause irreversible harm to the human body. This is the process of heavy metal poisoning. For heavy metals, we usually refer to metal elements with a density greater than 4.5 grams per cubic centimeter. There are more than 40 kinds in the chemical periodic table. These include lead, manganese, copper, mercury, iron, nickel and so on.

Next, let's learn about the effects of these heavy metals on the human body. Let's start with mercury. Mercury is mercury, the only liquid metal element at room temperature. It can also be said that it is a common metal in our lives. It is very unstable. If the temperature is higher, the mercury exposed to the air will evaporate quickly. Don't think it's okay to evaporate. When it evaporates to form mercury vapor, it will do great harm to the visual nerve of the brain. Therefore, if the mercury in the thermometer overflows, it should be absorbed by sulfur and then treated.

Followed by lead. Lead is also a common metal element in our life. Before lithium batteries appeared, we usually used lead batteries, and of course there are now. Lead is also widely used in cosmetics. If lead is difficult to be discharged once it enters the human body, it can directly harm the brain cells of the human body. And the damage is irreversible. So if we use lead-acid batteries, don't bury them in the soil. This will not only pollute the water, but also cause harm to the human body.

Excessive heavy metals will do harm to human body. But a very small amount of heavy metals are indeed trace elements in the human body. Such as iron, copper and manganese. So whether the heavy metal itself is toxic or not depends on the quantity.
