Lead content in wooden door paint
The quality of furniture paint not only affects the aesthetics of the room but whether the product is safe and environmentally friendly directly causes pollution to the indoor environment, and even harms our health. Therefore, you need to pay attention to the lead content when purchasing.
Lead-based paint standards
The U.S. Environmental Protection Agency considers paint that contains 0.5 percent or more lead, or 10 milligrams per square centimeter or more, to be lead-based. my country's "Limits of Hazardous Substances in Interior Decoration Materials and Interior Wall Paints" stipulates that soluble lead in interior wall paints shall not exceed 90 mg/kg.
Dangers of lead-based paint
Once lead in paint enters the human body through the respiratory tract, digestive tract, skin, etc., it will continue to accumulate in the blood, causing toxic reactions such as anemia, memory loss, high blood pressure, and joint pain. It has been determined that a paint chip the size of a fingernail contains 50 milligrams of lead.
Studies have found that infants and young children are the main victims of lead pollution. According to a survey by the Chinese Center for Disease Control and Prevention, one-third of children in my country still have excessive lead intake, and contamination from home decoration items is the most common source of lead contamination for children. Surveys show that at 1 meter above the ground, the lead concentration in the air is 16 times that at 1.5 meters, and children's heights are exactly within this range. Infants and young children often touch the wall with their hands. In addition, they have the habit of sucking their thumbs, so they are prone to ingesting a large amount of lead. In addition, the lead absorption rate of infants and young children is as high as 53%, which is about 5 times that of adults.
Sources of Toxicity of Lead-Based Paint
Lead-based paint is mainly caused by lead compounds contained in paint pigments, such as yellow lead, red lead, and lead white. Because it keeps paint colors bright for a long time, the more brightly colored the paint, the more likely it is to contain large amounts of lead.
Ways to Prevent Lead Poisoning
Some simple ways to prevent lead poisoning include cleaning floors and window sills regularly every week, vacuuming carpets, urging children to wash their hands frequently, especially before eating, and ensuring that children's diets are high in iron and calcium, and low in fat. It can make children absorb less lead from the environment.
Lead-based paint market status
At present, in my country's building materials market, many paints contain organic pigments, and some brands have advertised themselves as "environmentally friendly paints." According to professionals: "Brightly colored lead-based paint still occupies a large market share in China. Although white paint contains meager lead, people prefer bright colors." Therefore, consumers should try to choose environmentally friendly paint, even if they use ordinary paint, and choose lighter colors to minimize lead contamination.
