International action week for the prevention of lead poisoning: removing lead from paint international action week for the prevention of lead poisoning: removing lead from paint October 24, 2014

[China paint information] the World Health Organization recently issued a notice. The organization and the United Nations Environment programme launched the "international action week for the prevention of lead poisoning" globally on October this year. The theme is: removing lead from paint. The slogan is: cultivating lead-free children, Create a healthy future

important facts

● lead is a cumulative poison that affects multiple systems of the body, especially young children

● it is estimated that about 600000 children with mental retardation are caused by children's exposure to lead every year

● it is estimated that lead exposure causes 143000 deaths every year, and the large-scale production of complex plastic parts of negative batteries in developing countries bears the heaviest burden

● about one half of the disease burden caused by lead, even in the same shape, occurs in the WHO Southeast Asia region, while the WHO Western Pacific region and the eastern Mediterranean region each account for one fifth

● lead in the body is distributed in the brain, liver, kidney and bone. It is stored in teeth and bones and accumulates over time. Human exposure is usually estimated by measuring blood lead

● there is no known lead exposure level considered safe

● lead poisoning can be completely prevented

lead is a naturally occurring toxic metal in the earth's crust. Its widespread use has caused a wide range of environmental pollution, human contact and public health problems in many parts of the world

important sources of environmental pollution include mining, smelting, production and recycling activities, as well as the continuous use of lead-containing paint and gasoline in some countries. More than three-quarters of the global lead consumption to ensure product quality. The cost of consistency between batches is the production of motor vehicle lead-acid batteries. However, lead is also used in many other products, such as pigments, paints, welding, painted glass, crystal containers, ammunition, ceramic glazes, jewelry, toys, and some cosmetics and traditional medicines. Drinking water delivered through lead pipes or pipes connected with lead containing solder may contain lead. Much of the lead in global commerce is now obtained through recycling

young children are particularly vulnerable to the toxic effects of lead and have to endure serious and sustained health side effects, especially affecting the development of the brain and nervous system. Lead can also cause long-term damage to adults, including an increased risk of hypertension and kidney damage. Exposure of pregnant women to high concentrations of lead can lead to abortion, stillbirth, premature birth, low birth weight and minor deformities

sources and exposure routes

people may be exposed to lead through occupational and environmental sources. This is mainly due to:

inhalation of lead particles produced by burning lead containing materials, such as smelting, informal recycling, stripping of lead containing paint and the use of lead containing gasoline; Ingestion of lead contaminated dust, water (from lead containing pipes), food (from lead glazes or containers welded with lead)

the use of some traditional cosmetics and drugs can also cause lead exposure

young children are particularly vulnerable because they absorb four to five times as much lead from specific sources as adults. The secret is all in carbon fiber composites! In addition, children's natural curiosity and age-appropriate hand and mouth behavior will put lead or lead plated items into their mouth or swallow them, such as contaminated soil or dust and rotten lead paint flakes. This route of exposure has a greater impact on children with pica (who are always forced to eat non food items). For example, they may remove lead paint from walls, door frames and furniture and eat it. Exposure to lead contaminated soil and dust due to battery recycling and mining has resulted in large-scale lead poisoning and multiple deaths among young children in Senegal and Nigeria

once lead enters the body, it will be distributed to the brain, kidney, liver, bone and other organs. The body stores lead in teeth and bones and accumulates over time. Lead stored in bones may re free into the blood during pregnancy, thus exposing the fetus. Undernourished children are more vulnerable to lead because their bodies absorb more lead when they lack other nutrients such as calcium. High risk children belong to very young people (including developing fetuses) and poor groups
