Many families will choose bright colors when decorating their new homes in order to achieve a satisfactory decoration effect. However, such paints often have hidden health risks.
Lead paint standard
The U.S. Environmental Protection Agency treats paints that contain 0.5% or more of lead, or 10 mg/cm2, 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.
Lead paint hazards
Experts said 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, high blood pressure, 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. The survey showed that at a distance of 1 meter from the ground, the concentration of lead in the air is 16 times that at 1.5 meters. Children's height is within this range; infants and young children often touch the wall with their hands, and they have the habit of picking up their fingers. Ingest large amounts 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.
Toxic Sources of Lead Paint
Experts said that lead paint is mainly caused by lead compounds contained in paint pigments, such as Huangdan, Hongdan 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.
Prevention of lead poisoning
There are simple ways to prevent lead poisoning, such as cleaning the floor, windowsill, and carpet regularly every week; urge children to wash their hands often, especially before eating; ensure that the children’s diet contains high levels of iron and calcium and low fat. Can make children absorb less lead in the environment.
Lead paint market status
At present, in the building materials market in China, many of the paint ingredients include organic pigments, and some brands have used the signs of “green paintâ€. According to professional sources, “The brightly colored lead-based paint still occupies a large market share in China. Although white paint has a very low lead content, people prefer bright colors.â€
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.
