Decoration repair paint more fresh lead containing more

Many families choose colorful paints to decorate their new homes in order to achieve a satisfactory decoration effect. However, such paints are often buried with hidden dangers.

Standards for Lead Paints The U.S. Environmental Protection Agency treats paints with lead levels of 0.5% or more, or 10 mg/cm2 or more as leaded paint. China's “Restrictions on Harmful Substances in Interior Decoration Materials for Interior Wall Coatings” stipulates that soluble lead in interior wall coatings should not exceed 90 mg/kg.

Hazard of paint containing lead indicates that once the lead in the paint enters the body through the respiratory tract, digestive tract, and skin, it will continue to accumulate in the blood, causing anemia, memory loss, hypertension, joint pain and other toxic reactions. According to the test, the size of the paint on nails contains 50 mg of lead.

Studies have found that infants and young children are the main victims of lead pollution. According to a survey conducted by the Chinese Center for Disease Control and Prevention, there is still one third of children in China who consume excess lead, and home furnishings are the most common sources of lead pollution. According to the survey, the concentration of lead in the air is 16 times that of 1.5 meters at a height of 1 meter from the ground, and the height of children exactly falls within this range. Infants and young children often touch the wall with their hands, and they have the habit of picking up their fingers, making it easy to take in a lot of lead. In addition, the absorption rate of lead in infants and young children is as high as 53%, which is about 5 times that of adults.

Lead sources for the toxicity of lead paints indicate that lead paints are mainly caused by lead compounds contained in paint pigments, such as yellow dan, red dan and lead white. Because it can keep the paint color bright and long-lasting, the more colorful the paint, the more likely it is to contain a large amount of lead. Wang Yiqiang introduced that some institutions had done a test. Of the 23 samples containing lead paint, the orange paint had the highest lead content, followed by yellow, green and brown.

There are simple ways to prevent lead poisoning. There are some simple ways to prevent lead poisoning, such as periodically cleaning floors, windowsills, absorbing carpets, urging children to wash their hands frequently, especially before eating, and ensuring that children’s diets contain high levels of iron and calcium. As well as low fat, children are less likely to absorb lead from the environment.

Leading paint market status At present, in China's building materials market, many of the paint ingredients include organic pigments, and some brands have played the "green paint" signs. According to professional sources, “The brightly colored lead-based paint still has a large market share in China. Although white paint has a very low lead content, people prefer bright colors.”

Experts remind consumers that they should use green paint as much as possible, that is, use ordinary paint, but also choose a lighter color to minimize lead pollution.
