Lead is a multi-system and multi-compound heavy metal poison, and it is also a non-degradable environmental pollutant, which is harmful to human body. Because lead enters the human body through the digestive tract, respiratory tract and skin contact, workers who are often exposed to lead are also the main population of lead poisoning, mostly chronic accumulation poisoning. Mild poisoning can cause neurasthenia syndrome (such as dizziness, insomnia, fatigue and dreaminess) and digestive system symptoms (such as loss of appetite, nausea and abdominal discomfort); Anemia and abdominal cramps occur when poisoning is serious; In severe cases, lead paralysis or toxic encephalopathy occurs. If you don't have any protective facilities at work, the lead dust attached to you at work will inevitably pollute the family environment and affect the health of your family. It is recommended to take your family to the hospital for blood lead test. Supplementing some elements such as iron, calcium and zinc and eating more red meat, such as pork and beef, can reduce the blood lead level, and there is no need to spend money on health care products. Dietotherapy is an ideal way to get rid of lead. Add protein to the diet and eat more foods rich in vitamin C and acid. Garlic, carrot, kelp, mung bean, yogurt, milk tea, tea, dark plum, spinach, cabbage, lettuce, lemon, persimmon, grape, banana, apple, bean products, Smilax glabra, money and other foods or traditional Chinese medicines can be combined with lead to reduce lead toxicity or become non-toxic, while others can promote lead excretion. Here are some recipes for discharging lead and calming the nerves to choose from. The traditional Chinese medicines used are generally available in Chinese medicine shops.

50g of carrot, 50g of milk and 50g of carrot are cooked, taken out and crushed, and taken in 200ml of milk.

Flammulina velutipes 100g, cooked to remove soup, 50g shrimp skin, 200g lean meat slightly washed in warm water. Chop the above three things into mud, add seasoning to make stuffing, and wrap them into jiaozi (or wonton) for cooking, which can be eaten in batches.

50g of seaweed porridge with garlic15g of kelp, chopped and mashed with two cloves of garlic. Boil rice and kelp with appropriate amount of water first, add garlic paste and seasoning after porridge, cook for a while and eat it several times.

Jinmei drinks Lysimachia christinae 10g, Mume 10g, and Glycyrrhiza uralensis Fisch 10g, decocted for about 300ml, and taken in three times.

Licorice and mung bean soup: licorice 10g, mung bean 50g. Cook the soup until the mung beans are crisp and rotten. No sugar, soup and mung beans.

Golden chicken soup with Lysimachia christinae 10g and Smilax glabra 6g. Decoct the juice to 300ml, remove the residue, add chicken 150g (not for the head and claws), cook Tongan seasoning, and eat the soup with the chicken.

The above recipes can be taken alternately for a long time, generally 1~2 months or longer. Children with symptoms of lead poisoning may wish to have a try.

Lead poisoning can be divided into the following grades and treatment methods;

Grade I: 10ug/dl: it is a relatively safe blood lead level; No treatment is needed.

Grade II-A: 10- 14ug/dl, mild lead poisoning, no need for treatment, just leave the lead source.

Grade II-B: 15- 19ug/dl, mild lead poisoning, eating foods rich in zinc, iron, calcium, vitamin B and C to resist lead toxicity and promote lead excretion.

Grade ⅲ: 20-44ug/dl, moderate lead poisoning.

Grade ⅳ: 45-69ug/dl, severe lead poisoning.

Treatment of moderate and severe lead poisoning;

Non-drug lead excretion: metallothionein biological beverage

Drug lead excretion: disodium calcium edetate, dimercaprol, promoting excretion.

You can try Qianguohua oral liquid. In addition, reducing the exposure of lead pollution, eating more fresh vegetables and fruits and keeping the balance of trace elements such as calcium, zinc and iron are also good ways to drive away lead.

Eleven methods to prevent lead pollution

● Children should develop the good habit of washing their hands frequently, paying special attention to washing their hands before eating.

● Children should cut their nails frequently, and it is especially easy to hide lead dust under the nails.

● Always clean children's toys and other items that may be put into children's mouths.

● Bedrooms located near busy roads or industrial areas should be wiped with wet wipes as often as possible to remove dust where children can reach. Put a lid on the nipple of food and bottle.

● Don't take children for a walk and play near busy roads and lead factories.

● Workers directly engaged in lead work must take a shower and change clothes before going home. Workers who may have lead pollution in the workplace and those who work on the roadside all day should also change clothes and wash their hands before leaving work. Don't wash work clothes with the clothes of family and children.

● Families using coal as fuel should open windows for ventilation as much as possible.

● Children should eat less foods with high lead content, such as preserved eggs and popcorn.

● When tap water is used every morning, the tap should be turned on for about 1-5 minutes, which will discard some water that may be contaminated by lead the night before (the lead content of tap water pipe materials was high in earlier years). Never use the tap water in the first paragraph of the morning to cook and prepare milk for children.

● Children should have a regular diet, and the absorption rate of lead in the intestine increases exponentially on an empty stomach.

● Ensure that children's diets contain enough calcium, iron and zinc. Foods rich in calcium are: dairy products, bean products, animal bones and so on. Foods rich in iron are: animal liver, animal blood, meat, eggs and so on. Foods rich in zinc include meat and seafood (especially shellfish).

At present, there are no effective drugs and foods to expel lead. There is a truth that parents need to master: because lead and calcium are divalent ions, they may compete for receptors after entering the human body. From this point of view, children with calcium deficiency are vulnerable to lead pollution. Pay attention to calcium supplementation for children.

Studies have shown that the possibility of lead poisoning in children is more than 30 times that of adults.

Reference article: Why are children prone to lead poisoning?

Usually people consume a lot of lead in the form of lead dust. Inhaled lead dust adheres to the respiratory mucosa, and adults can excrete most of it through normal physiological reaction-spitting, while children cannot form this reaction because they are immature and are completely absorbed into the human body.

The characteristics of children's growth and development determine that children absorb more lead and excrete less lead:

1, children's hands and mouth move more, and lead enters through the mouth;

2. Children have a high demand for food and oxygen and a high intake of lead;

3. Children's tissues are immature, and lead poisoning is easily absorbed into the blood through the lungs and gastrointestinal tract;

More than 4.80% lead flows below the ground 1 m, which is the life circle of children;

5. Children can only get rid of 2/3 lead through the kidney.

Children are very sensitive to the harmful effects of lead poisoning. Because children's blood-brain barrier is underdeveloped and has strong permeability, blood lead can easily poison the brain through the brain barrier. Studies have shown that under the same conditions, the amount of lead that children pass through the blood-brain barrier is 18 times that of adults. One of the serious consequences of blood-brain barrier dysfunction caused by lead poisoning is that the water in blood vessels penetrates into the interstitial space of human brain, causing brain edema, thus making brain cells return to zero and causing mental retardation. If lead poisoning is not eliminated in time, with the development of blood-brain barrier, it is difficult to eliminate lead stored in the brain. The most terrible thing is that this kind of injury is irreversible and permanent.

Regular consumption of the following foods can effectively remove toxic substances from the human body:

1. Fungal foods: such as auricularia auricula, tremella, mushrooms and shiitake mushrooms.

These fungi are rich in selenium. Regular administration can lower blood pressure and cholesterol, prevent arteriosclerosis and improve immune function.

Increase the content of immunoglobulin in the body, stimulate the hematopoietic function of bone marrow, smooth intestines, clear blood, remove toxins and increase intelligence.

2. Kelp: The fucoidan in kelp can treat arteriosclerosis, prevent the human body from absorbing heavy metals such as lead and cadmium, and eliminate radioactive elements in the human body. Because of the high water content of fucoidan, it can form gel-like substances in the intestine, so it is helpful to eliminate toxic substances and prevent constipation and intestinal cancer.

3. Pig blood: After the plasma protein of pig blood is decomposed by gastric acid and digestive juice, it can produce a substance with intestine moistening and detoxification effects. This substance can react chemically with dust and harmful metal particles attached to the gastrointestinal wall, so that these toxic and harmful substances are excreted.

4. Fresh fruit juice and vegetable juice: Fresh fruit juice and vegetable juice can make the blood alkaline after entering the human body, thus dissolving the toxins accumulated in cells and then discharging them from the body.

5. Foods containing more carotene: These foods include laver, pumpkin, melon, carrot, orange, sweet potato, pumpkin, persimmon, papaya, Gan Lan, orange, liver, milk, egg yolk and fish.

6. Mung beans: Mung beans can relieve alcoholism, wild mushroom poisoning, arsenic poisoning, organophosphorus pesticide poisoning, lead poisoning, erysipelas poisoning and rodenticide poisoning. Chinese medicine believes that mung bean can treat all kinds of poisons, help the excretion of poisons in the body and promote the normal metabolism of the body.
