What kind of harm will excessive heavy metals in food cause to the human body?

The metabolism of heavy metals in the human body is relatively slow, and heavy metal poisoning can easily cause dizziness and nausea, and damage the human nervous system and central system.

Excessive heavy metals in food will seriously affect the function of the human kidneys, which will cause great damage to the kidneys, and is likely to cause kidney failure, so excessive heavy metals in food is a very serious problem.

If humans consume too much heavy metals, then a series of diseases may occur, such as some vascular diseases or kidney diseases.

Heavy metal contaminants in <> food include lead, arsenic, chromium, cadmium, mercury, cobalt, manganese, etc.

1. Lead is one of the most toxic heavy metal pollutants, which can directly harm human brain cells;

2. Arsenic is carcinogenic, and long-term exposure can easily lead to chronic poisoning;

3. Chromium is easy to cause diarrhea, tuberculosis, bronchitis and dermatitis;

4. Cadmium is mainly accumulated in the kidneys, which can easily lead to functional changes in the urinary system;

5. Mercury is a highly toxic substance, which is extremely damaging to nerves and vision;

6. Cobalt can cause radioactive damage to **;

7. When manganese is excessive, it causes hyperthyroidism and harms the vital organs of the human body.

Hello, the effects of heavy metals on the human body are very slow and long, and once they enter the human body, the metabolism is very difficult. Taking lead as an example, Xinhuanet pointed out that lead accumulates in living organisms, and long-term exposure to low concentrations of lead can affect the development of the cardiovascular and central nervous systems, especially fetuses and infants. Long-term intake of foods with high levels of lead can affect the development of the nervous system and intelligence, and may be dangerous to human health. ”

With the development of modern industry, heavy metal pollution has become one of the environmental problems that people are very concerned about. Heavy metals are an element that is ubiquitous in the natural environment, but they can also be discharged into soil and water by human activities, contaminating food. Food is a necessity in people's lives, and the possibility of heavy metals in food cannot be ruled out.

The harm of heavy metals to the human body is very serious and will also affect people's health.

First of all, heavy metal pollution can cause damage to the nervous system in humans. For example, lead is a heavy metal element, and long-term exposure to lead can cause damage to the human nervous system. The World Health Organization generally believes that the safe concentration of lead in a child's blood should be less than 100 micrograms.

However, the harm of lead to the human body lies in the fact that even very low concentrations can damage children's mental development. Heavy metals such as chromium and cadmium can also have a negative impact on the nervous system. Cadmium is similar to lead but more toxic and can cause severe liver and kidney damage.

Secondly, heavy metal pollution can also have a negative impact on the human reproductive system. This effect may include threats to a person's sexual maturity and reproductive abilities. For example, long-term exposure to lead in women can have an impact on the reproductive system, especially reducing fertility.

Finally, heavy metal contamination may also affect a person's immune system. This effect can threaten the health of the person's immune system, forming diseases that cannot be combated. In addition, the long-term accumulation of heavy metals in food may lead to food poisoning.

In summary, the presence of heavy metal contamination in food has a negative impact on human health. People should pay attention to protecting the environment, mitigating contamination of food, and mitigating the negative impact on the human body and ecosystem.

1. Mercury: It sinks directly into the liver after ingestion, which greatly damages the vision nerve of Dayuan Sizzi's brain. Natural water contains milliliters per liter of water, which can be highly toxic. Drinking water containing trace amounts of mercury can cause cumulative poisoning when consumed for a long time.

2. Chromium: It can cause numbness of limbs and mental abnormalities.

3. Cadmium: causes hypertension and cardiovascular and cerebrovascular diseases; Destroys bone calcium, causing kidney dysfunction.

4. Lead: It is one of the more toxic heavy metal pollution, and it is difficult to eliminate it once it enters the human body. Direct damage to human brain cells, especially the neural plates of the fetus, can cause congenital cerebral sulcus gyrus and mental retardation; It causes dementia and brain death in the elderly.

5. Cobalt: Radioactive damage to **.

6. Vanadium: hurts people's heart and lungs, and leads to abnormal cholesterol metabolism.

7. Antimony: and arsenic can make the silver hand ornament brick red, which has strong damage to the first class.

8. Thallium: It can cause polyneuritis.

9. Manganese: Excessive amounts will cause hyperthyroidism.

10. Tin Hail Wang: It is an important ingredient in the ancient poison 'lury' in the ancient poison, which solidifies into a lump after entering the abdomen, causing death.

11. Zinc: Zinc poisoning can occur in excess.
