How to remove lead from children

Lead is very harmful to human health. Lead poisoning not only exists in the air, but may also be hidden in some older houses, garden land, etc. Sometimes it may be hidden in children's toys, which can easily lead to lead poisoning in children. If the lead content in a child's body is too high, it will seriously affect the child's physical and mental health. In daily life, how can we help children remove lead?

How to remove lead from children?

1. Foods rich in vitamin C

Vitamin C combines with lead to form a substance that is insoluble in water and is then excreted from the body with feces. Vitamin C is widely present in fruits, vegetables and the leaves of some plants. Sour fruits such as oranges, lemons, pomegranates, hawthorns, especially sour dates, are the richest in them. Apples, strawberries, fresh peppers, cabbage, garlic sprouts, snow vegetable, tomatoes, cauliflower, etc. also contain vitamin C.

2. Foods rich in protein and iron

Protein and iron can replace lead and bind to organic matter in tissues, accelerating lead metabolism. Foods containing high-quality protein include eggs, milk and lean meat. Green leafy vegetables and fruits rich in iron include spinach, celery, rapeseed, radish tops, amaranth, shepherd's purse, tomatoes, citrus, peaches, plums, apricots, pineapple and red dates.

Where does the lead in children's bodies come from?

1. Soil

Under normal circumstances, the lead content in soil is 10-50 mg/kg, but the lead content in soil in urban areas may be hundreds or even thousands of times higher. In addition to children directly touching the soil with their hands, the soil stuck to the soles of their shoes can also easily be brought into the room.

2. Dust on the indoor floor

Airborne lead dust that settles on floors or carpets is also an important source of lead exposure for children.

3. Water pipes in old houses

Although the lead content in tap water is not high, its bioavailability is often higher than that of lead in food. Lead contamination is usually more likely to occur in tap water pipes in old homes.

4. Home decoration materials

The main components of paints, coatings and wallpapers in home decoration materials are lead salts, cadmium, chromium oxide, lead yellow, lead white, red lead, etc. Many decorative materials such as wood coatings and interior wall coatings contain lead. Some families like to decorate their rooms, especially children's rooms, in colorful colors, which can more easily cause lead pollution in the room air.

5. Daily necessities

Cigarette smoke, cosmetics, lead-containing containers, tableware made of colored glaze ceramics, milk bottles and water cups printed with various bright patterns, etc.

6. Jewelry

Especially jewelry with painted surfaces, such as necklaces, jewelry, etc., children like to play with them and even put them in their mouths.
