White paint is safer than bright colors

Many families choose bright colors when they decorate their new homes in order to achieve satisfactory decoration effects, but such paints often harbor health hazards.

Lead paint standard

The US Environmental Protection Agency treats paints that contain or exceed 0.5% lead, or 10 mg or more per square centimeter, as lead paint. China's "Limits of Hazardous Substances in Interior Finishing Materials Interior Wall Coatings" stipulates that soluble lead in interior wall coatings shall not exceed 90 mg/kg.

The danger of lead paint

Experts said that once the lead in the paint enters the human body through the respiratory tract, digestive tract, skin, etc., it will continue to accumulate in the blood, causing anemia, memory loss, high blood pressure, joint pain and other toxic reactions. It has been determined that nail-sized paint debris contains 50 mg of lead.

Studies have found that infants and young children are the main victims of lead pollution. According to the China Center for Disease Control and Prevention, there are still one third of children in China who consume excessive lead, and home decoration pollution is the most common source of lead pollution for children. According to the survey, the lead concentration in the air is 16 times that at 1.5 meters from the ground. The height of the child is just in this range; infants often touch the wall with their hands, and they have the habit of rubbing their fingers. Ingest 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.

Toxic source of lead paint

Experts say that lead paint is mainly caused by lead compounds contained in paint pigments, such as yellow dan, red dan and lead white. Because it keeps the color of the paint bright and durable, the more vivid the paint, the more likely it is to contain a lot of lead. Wang Yiqiang introduced that there was a test conducted by the agency. Among the 23 samples containing lead paint, the orange paint had the highest lead content, followed by yellow, green and brown.

Method for preventing lead poisoning

There are some simple ways to prevent lead poisoning, such as cleaning the floor, window sill, and carpet regularly every week; urging children to wash their hands frequently, especially before eating; ensuring high levels of iron and calcium and low fat in children's diets. It can make children less absorbed in the environment.

Lead paint market

At present, in the building materials market in China, many paints include organic pigments, and some brands have branded “green paint”. According to professionals, “Colorful lead paints still have a large market share in China. Although white paints contain very low levels of lead, people prefer bright colors.”

Expert reminder

Consumers should try to use environmentally friendly paints, that is, use ordinary paints, and choose a lighter color to minimize lead pollution.
