Heavy metals refer to metals with greater density, including gold, silver, copper, iron, mercury, lead, cadmium, etc., which accumulate in the human body to a certain extent, causing chronic poisoning.
In terms of environmental pollution, heavy metals mainly refer to heavy elements with significant biological toxicity such as mercury, cadmium, lead, chromium and arsenic.
Heavy metals are very difficult to biodegrade, but on the contrary, they can be enriched thousands of times by the biomagnification of the food chain and finally enter the human body. Heavy metals can interact strongly with proteins and enzymes in the human body, making them inactive, and may also accumulate in some organs of the human body, causing chronic poisoning.

There are 5 kinds of people who are most harmful to the human body: such as lead, mercury, chromium, arsenic, cadmium, etc. These heavy metals cannot be broken down in water and combine with other toxins in the water to form more toxic organic matter.
Other hazards to the human body are: aluminum, cobalt, vanadium, antimony, manganese, tin, thallium, etc. Well.
-
The heavy metal elements that are harmful to the human body mainly include lead, mercury, cadmium, and chromium. Copper, iron, manganese and zinc exceeding the standard are harmful to the human body, and there are many other harmful elements, but they are not heavy metals.

It can make people more beautiful, of course, not only because the decoration makes people look more beautiful. **Because the internal molecular structure is very stable, it has a certain degree of oxidation resistance.
It can help inhibit the body's absorption of more peroxidation, thereby slowing down the rate of aging.
Disadvantages: jewelry dermatitis, some women wear rings, necklaces and other parts of the neck and fingers contact dermatitis, itching, erythema, peeling, pimples.
In severe cases, asthma may even be induced.
or generalized urticaria.
**Jewelry care precautions.
**Soft and easy to deform, so try to avoid colliding with sharp objects when wearing, do not pull necklaces and other jewelry to avoid deformation, and avoid wearing **jewelry, especially wearing rings when doing heavy work.
Gold has a comparatively low hardness. For example, when jewelry, clothing, food, housing and skin care products such as clothing, food, housing and transportation, chemical elements such as mercury or chlorine are found in organic chemical utensils.
After contact, it can form an attachment of white alloy on its surface, which will be mistaken for a discoloration of **. When you don't wear a ** ring for a long time, you should use flannel first.
Wrap it and put it in a jewelry box so that it doesn't rub against and damage other jewelry.

Lead, mercury, chromium, arsenic, cadmium, aluminum, cobalt, vanadium, antimony, selenium, thallium, manganese, tin, etc. From the aspect of environmental pollution, heavy metals refer to heavy metals with significant biological toxicity such as mercury, cadmium, lead, chromium and arsenic.
Lead: harms human brain cells, causes cancer and mutagenesis, etc.
Mercury: It sinks directly into the liver after ingestion, and damages the brain's mental eyesight. Natural water, which contains milligrams per liter of water, can be highly toxic.
Chromium: It can cause numbness of the limbs and mental abnormalities.
Arsenic: can cause hyperpigmentation and lead to abnormal keratinization.
Cadmium: causes high blood pressure, causes cardiovascular and cerebrovascular diseases; Destroys bone calcium, causing kidney dysfunction.
Aluminum: When it accumulates a lot, it causes mental retardation in children; Causes memory loss in middle-aged people; Dementia in the elderly, etc.
Cobalt: It can cause radiation damage to **.
Vanadium: hurts people's hearts and lungs, and causes abnormal cholesterol metabolism.
Antimony: and arsenic can make silver hand ornaments brick red, and have radioactive damage to **.
Selenium: When the amount is excessive, people can get stumbling disease.
Thallium: It can cause more and more neurosis in people.
Manganese: When excessive, it can cause hyperthyroidism.
Tin: and lead are important components in the ancient giant poison & dove, which solidified after entering the abdomen.

This problem is too wide, there are many, many metals, and in reality, alloys are used more. Common metals and their uses are as follows:
1。Silver is used as a filling agent for silver coins, electronic devices, and dentists;
2。Gold is used as ornaments and gold coins;
3。Aluminum is used for cables, aluminum cans, and aluminum windows;
4。Copper is used for wires, musical instruments, and water pipes;
5。Iron is used for railways, ships, iron bridges, and railings;
6。Zinc is used to plating the surface of iron, so that the iron is not easy to rust;
7。Tin is used to plating mild steel to prevent it from coming into contact with oxygen and people. Slows down the rate at which steel rusts.
Metal is a substance with shiny, malleable, easy to conduct electricity, heat and other properties.
The vast majority of metal elements on Earth exist in nature in a chemical state. This is because most metals are chemically active, and only a very small number of metals such as gold and silver exist in a free state.
Metals are widely present in nature and are extremely common in life, and are a very important and most widely used class of substances in modern industry.

The harm of heavy metals to the human body, heavy metals mainly refer to mercury, cadmium, lead, chromium and arsenic and other metals with significant biological toxicity, heavy metals are very difficult to be biodegraded, on the contrary, they can be enriched thousands or hundreds of times under the biomagnification of the food chain, and finally enter the human body. Heavy metals can have strong interactions with proteins, enzymes, etc. in the human body, making them inactive, and may also accumulate in some organs of the human body, causing chronic poisoning.
Heavy metals are commonly harmed to the human body such as mercury, food mercury directly sinks into the liver, the optic nerve of the brain is extremely damaging, containing trace amounts of mercury drinking water, long-term use will cause cumulative poisoning. Chromium can cause numbness and mental abnormalities in the limbs; Cadmium can cause high blood pressure, cause cardiovascular and cerebrovascular diseases, destroy bone calcium, and cause kidney dysfunction. Lead is a kind of heavy metal pollution that is relatively toxic, once it enters the human body, it is difficult to eliminate, directly injure human brain cells, especially the neural plate of the fetus, which can cause congenital cerebral sulcus shallowness, mental retardation, and dementia and brain death to the elderly.

Heavy metals are extremely harmful to the human body. The common ones are:
Mercury: It sinks directly into the liver after ingestion, and is extremely damaging to the brain, nerves, and vision. Natural water contains milligrams per liter of water, which can cause poisoning in people.
Cadmium: causes high blood pressure, causes cardiovascular and cerebrovascular diseases; Destroying bones, liver and kidneys, and causing kidney failureLead: one of the most toxic heavy metal pollutions, once it enters the human body, it will be difficult to eliminate. It can directly harm human brain cells, especially the nervous system of the fetus, and can cause congenital mental retardation.
Cobalt: It can cause radiation damage to **.
Vanadium: hurts people's hearts and lungs, and causes abnormal cholesterol metabolism.

What are the dangers of heavy metals to people? There are many harms to people, which can cause damage to liver and kidney function, cause liver disease or kidney disease, and seriously cause organ failure.
It's harmless and unhelpful, it's just some glue.
Copper is a heavy metal, and the trace elements required by the human body are iron, zinc, copper, iodine, lead, etc., so the human body is within the allowable content range, and the copper element is beneficial to the human body, but if it exceeds the standard, it will be poisoned.
1. If the copper is several times higher, copper poisoning may occur. Hemolysis and hemoglobin may occur in copper poisoning. >>>More
Argon itself is not toxic, but it has a suffocating effect at high concentrations. There is a risk of suffocation when the concentration of argon in the air is higher than 33%. When the concentration of argon exceeds 50%, severe symptoms appear, and when the concentration reaches more than 75%, death can occur within minutes. >>>More
