Recently, the United States today Medical News Network reported that a study from the University of Cincinnati, United States found that China, India, Malaysia and other countries are still producing and selling paint with high lead content, and this paint has long been banned in the United States. Therefore, the university urged all countries in the world to stop using paint containing lead. This news once again led to "lead paint" into the people's attention.
Lead paint is harmful to children What kind of paint is lead paint? The U.S. Environmental Protection Agency treats paints that contain 0.5% or more of lead, or 10 mg per square centimeter, 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.
Speaking of the hazards of paint containing lead, Wang Yiqiang, deputy secretary-general of the China Building Decoration Association, 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, and 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, in 1990, 57.5% of children aged 2 to 7 years old in China had excessive lead intake, and in 2000 the number rose to 62.1%. Currently, one third of children are still taking excessive lead. . Among them, home furnishings pollution is the most common source of lead for children. The survey showed that at a distance of 1 meter from the ground, the concentration of lead in the air is 16 times that of 1.5 meters. Children's height is exactly within this range. Infants and young children often touch the wall with their hands, and they have the habit of picking up their fingers. Into 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.
Where does the toxicity of lead paint come from? Wang Yiqiang said that it 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.
The United States has long prohibited the use of lead paint. The United States was one of the countries that earlier realized the danger of lead pollution. The U.S. federal government stipulated as early as 1978 that it prohibited the production and use of lead paint. The Chinese master Shen, who has long been engaged in home decoration, told reporters that at present, the American market has not been able to buy lead-based paints. They are generally replaced by resin paints and other environmentally-friendly paints, which makes them feel at ease during the renovation.
The U.S. Environmental Protection Agency also made recommendations to residents of old houses living before 1978, including: It is recommended that parents bring 1-2 year-old children to check the lead content in the blood, and ask professionals to sample and analyze the paint in the house. To determine if lead contamination has occurred. In addition, there are some simple methods, such as regularly cleaning the floor, window sill, and absorbing carpets every week; urging children to wash their hands often, especially before eating; ensuring that the children's diet contains high levels of iron and calcium and low fat, Can make children absorb less lead in the environment.
The U.S. Environmental Protection Agency had stipulated that painters must be trained before using paint, including when to allow painting, warning signs before painting, dust in the work area, thorough cleaning after painting, and work stoppage when children are present. And advised him to leave.
Both China and India are using leaded paint in several Beijing building materials markets visited by reporters. Many of the paint ingredients include organic pigments. There are also some brands that display the signs of “green paintâ€. Mr. Wang, editor-in-chief of China Paint Information Network, revealed to reporters: “The brightly colored lead-based paint still has a large market share in China. Although the white paint has very low lead content, there are not many people who use it. People prefer bright colors. Color.†Wang Yiqiang, deputy secretary-general of the China Building Decoration Association, also stated that due to process restrictions, Chinese paint products are still difficult to meet international standards, but fortunately, some manufacturers are aware of the pollution problems of lead paint and are actively developing. Green paint made with natural pigments.
Sunil, the head of a non-governmental organization called Pollution Prevention Association in Delhi, India, told reporters that lead contamination of paint is “very serious†in India, especially in schools and public facilities. Red and other bright colors paint. However, so far, the Indian government has not imposed any restrictions on lead paint.
Wang Yiqiang reminded 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.
