Lead is a toxic heavy metal that is extremely harmful to the human body and the environment.
On December 25, 2017, the environmental protection organization 'Zero Waste Environmental Public Welfare Development Center' released a survey report on the lead content in paint. The report shows that more than one third of the domestic paint lead content exceeds the standard, shocking. Exceeding the standard paint contains mostly lead. Different lead compounds are added as pigments. For example, lead carbonate will form white or milky white paint, and lead trioxide will form bright red paint.
Lead, a heavy metal additive, will also reduce the time it takes for pigments to dry out, making the pigments more durable and moisture-resistant. There are environmental groups collecting home improvement markets in Beijing, Shenyang, Zhengzhou, Nanchang, Guangzhou, Xiamen, Shanghai and Kunming , Solvent-based enamel paint at retail stores, involving a total of 47 well-known paint companies (Beijing Red Lion, Tianjin Lighthouse, Shenyang Gold Pegasus, etc.) and 47 brands, for a total of 141 cans, of which 37% The upper limit of the standard - 90 mg / kg, the maximum content of 4630 mg / kg.
The person in charge of Zero Waste Environmental Public Welfare Development Center in Shenzhen told Life Times reporter: 'This means that more than one third of the paint products tested in this survey were infringed on the market. In addition, another 48 cans (34% of all coatings) has reached the international level of dangerousness (more than 10000 mg / kg), which seriously jeopardizes human health. 'In 2001, China introduced the regulations on the lead content of indoor coatings and decorative coatings, Lead paint soluble lead content limit of 90 mg / kg.
Industry insiders said that at present, China is the only country that limits the lead content in interior paints in the form of a soluble lead content ceiling, a measure that does not prevent lead exposure or provide health protection and in many cases seriously underestimates Lead and its harm to the body lead poisoning affect the child's intelligence Long-term concern for environmental health Beijing Normal University Ph.D., Beijing zero-waste promoter Mao pointed out: 'Lead-based paint widely exist in ordinary people's families, and lead Exposure can cause lifelong irreversible effects on children's brains and can not be cured. "Lead is extremely harmful to the human body and the environment, leaving children with much lower levels of lead exposure than adults, and younger children are more at risk of lead and nutrition Poor children will take lead more rapidly, and the fetus is the most vulnerable, and pregnant women may transfer lead that accumulates in their body to their children.
Lead can also be transmitted through the breast milk if the mother is breast-feeding, and lead exposure during childhood can lead to mental retardation. Lead poisoning can damage the nervous system and lead to irritability, abdominal pain, loss of appetite, poor concentration and unresponsiveness in children , Memory loss, serious lead poisoning encephalopathy, or even death.While the World Health Organization (WHO) has identified lead as the most toxic toxic chemicals to children.Leaded paint is the main trigger of lead poisoning in children.When the wall , Lead, dust, and soil that lead to paint when windows, doors, or other objects begin to peel or burn lead Children playing indoors or outdoors can get leaded dust or soil from their hands and then touch the hands Lead into heavy metals, which is also the main route of infringement.Products lead should be clear that at present, China and many other countries still sell lead paint, used to decorate homes and schools.World Health Organization called for all countries should be phased out by 2020 lead Paint to protect the health of this and future generations.
The industry suggested that China speed up the phase-out of lead paint, the parties need to work together.The government can encourage all parties involved in the phase-out of lead paint battles to go, such as the relevant departments, coatings and non-governmental organizations, etc .; to develop effective rules and regulations to protect the country Paint lead content control law implementation; revision of the current paint lead content control method, in line with international standards, marked on the paint label lead dust hazard warning.
The paint industry should discontinue the use of lead and lead driers as coating ingredients; provide lead content information on the product label; provide warning labels to alert users to potential lead dust hazards when removing the old finish; Industry associations, raw material suppliers and research institutions with the help of lead-free paint production, strive for a win-win environmental and economic benefits.We suggest that consumers take the initiative to purchase lead-free paint, paint exclusion of lead; Beware of lead paint and lead dust risk, And take precautionary measures to minimize the probability of lead poisoning.If the regular cleaning of the floor every week, windows, children are urged to wash their hands frequently, especially before eating to ensure that children eat more iron and calcium and low fat, both Can make children less absorption of lead in the environment.
Insiders said: 'Currently there is no marking of the amount of lead in the paint sold, the experts called for the addition of lead and other harmful substances, I hope the manufacturer stated. Just as smoking is harmful to health.'
