Intellectual and emotional development of children can be damaged by the level of lead in blood, although in the threshold that is considered safe. Therefore, the content of lead in blood that is safe (10 micrograms per deciliter) should be lowered below 5 micrograms per deciliter.
Scientists from the University of Bristol, London, as reported by Reuters, studied a sample of 500 children and found a clear relationship between blood lead levels with academic achievement and behavior of children aged 7 and 8 years.
Content of lead in blood is higher in children aged 30 months, causing the child is weak in a good achievement in reading, writing, and spelling in children. Their achievement under the standard assessment tests (Standard Assessment Tests), a recognized standard test in that age group in England.
Bad behavior and hyperactivity are also commonly occur in children with higher lead levels in children are just learning to walk.
The UN World Health Organization (World Health Organization) estimates that half of children under five years of living in cities around the world have lead content in blood above 10 micrograms per deciliter. Researchers found, the content of lead in blood of 5-10 micrograms per deciliter resulted in significantly weaker children in reading (49 percent lower) and writing (51 percent lower).
Children who have blood lead content of more than 10 micrograms per deciliter nearly tripled antisocial behavior and hyperactivity than womb range 0-2 micrograms per deciliter.
The younger the age of the child, the more severe consequences of exposure to lead in the blood. Because the lead more easily absorbed body and destroy tissue berkaibat.
The decline of lead as an environmental toxin is done by changing the use of gasoline or kerosene, which is still found in paint, water pipes, toys, and other sources.
