What are the heavy metals that are harmful to the human body

Heavy metals are substances that are harmful to the human body, and there are a lot of such metals. We also come into contact with them in our daily lives. As we all know, many children have high lead content, which is also a situation caused by heavy metals. It has a serious impact on the growth of children. Generally, lead is mainly caused by automobile exhaust emissions, so we must pay attention to it in our lives. Let’s take a look at what heavy metals are harmful to the human body?

In chemistry, metals are divided into heavy metals and light metals according to their density. Metals with a density greater than 5g/cm3 are often called heavy metals, such as gold, silver, copper, lead, zinc, nickel, cobalt, chromium, mercury, cadmium, etc., about 45 types.

Among them, there are five types that are most harmful to the human body: lead, mercury, chromium, arsenic, and cadmium. These heavy metals cannot be decomposed in water and combine with other toxins in the water to form more toxic organic matter. Other elements that are harmful to the human body include: aluminum, cobalt, vanadium, antimony, manganese, tin, thallium, etc.

Common harms of heavy metals to the human body include:

Lead: damages human brain cells, causes cancer and mutations, etc.

Mercury: After ingestion, it sinks directly into the liver and causes serious damage to the brain, nerves and vision. If natural water contains 0.01 mg per liter, it will cause severe poisoning.

Chromium: can cause numbness of the limbs and mental abnormalities.

Arsenic: It can cause skin pigmentation and lead to abnormal keratinization.

Cadmium: causes high blood pressure and cardiovascular and cerebrovascular diseases; destroys bone calcium and causes kidney dysfunction.

Aluminum: When accumulated for a long time, it will cause mental retardation in children, memory loss in middle-aged people, and dementia in the elderly.

Cobalt: Can cause radioactive damage to the skin.

Vanadium: damages the heart and lungs, and causes abnormal cholesterol metabolism.

Antimony: It and arsenic can turn silver jewelry into brick red and cause radioactive damage to the skin.

Selenium: Excessive intake can cause staggering.

Thallium: It can cause multiple neuritis.

Manganese: Excessive intake can cause hyperthyroidism.

Tin: It is an important component of the ancient poison "Jiu" along with lead. After entering the stomach, it solidifies into

Through the above introduction, we know that there are heavy metals that are harmful to the human body, and there are a lot of such metals. Generally, they will cause serious effects on the human body and even cause diseases. We must pay attention to prevention in our daily lives, especially try to avoid walking on the road frequently, and also pay attention to exercising the body in daily life.
