What are the effects of high lead levels on children?

In life, people need to pay attention to the effects of some elements on the body. For example, metal elements can bring many side effects to the body, especially the impact on children is the greatest. For example, lead is a heavy metal. Excessive intake by the human body can cause serious health problems. Let’s take a look at the impact of extremely high lead content on children. I hope everyone can understand it.

Infants and young children are in a critical period of brain development. Excessive exposure to lead can cause brain damage that is often irreversible, and some of the harmful health effects will be long-term or even lifelong.

According to the relevant regulations of the Ministry of Health of my country on the classification of children's hyperleademia and lead poisoning, a child's blood lead content of 100ug/L--199ug/LL is considered hyperleademia (internationally considered to be mild lead poisoning within this range); lead content greater than or equal to 200ug/L is lead poisoning.

Among them, lead poisoning is divided into three levels: mild, moderate and severe, which are blood lead levels of 200ug/L--249ug/L, 250ug/L--499ug/L and blood lead levels greater than or equal to 450ug/L.

Excessive blood lead levels can cause many kinds of harm to children's health, and the degree of harm is proportional to the blood lead level in the body.

What lead-containing items do children come into contact with in daily life?

1. Stationery

When we hear the word "lead type", we naturally think of pencils. However, the pencil lead does not actually contain lead, but the colored paint on the outside of the pencil does contain lead. Children usually put pencils in their mouths and can easily swallow a lot of lead.

In addition to pencils, oil pastels or crayons used by children for drawing also contain lead. Newly bought oil pastels and crayons are wrapped in a layer of paper to prevent children from direct contact with the lead, so parents should pay attention to prevent children from tearing off the outer wrapping paper.

2. Furniture

Furniture in your home also contains a lot of lead because lead is an additive in many paints. In particular, parents like to buy brightly colored furniture for their children, and even paint their children's rooms in colors, which invisibly exposes their children to more lead.

3. Toys

Many toys also use paint on their eyes, mouths, hands and feet. If children like to sleep with their toys in their arms, they will inadvertently inhale more lead.
