Insecticide
threat to children's brain development
A new U.S. study shows that pregnant women who are subjected to rates, although moderate, of insecticide commonly used expose their children to permanent changes in the brain lead to retarded growth.
The study, published in the journal "Brosidings Of The National Academy of Sciences", pregnant women of New York had experienced "chlorpyrifos - ethyl", an insecticide commonly used in fields and parks.
The researchers compared 20 children aged between 5 and 11 years whose mothers were exposed to high levels of pesticide in question, and 20 other mothers were exposed to lower rates of it, They observed "significant disabilities" in the first group.
Said study author Virginia Roh that "this study shows that the prenatal period essential for the growth of the fetus," and that exposure "to toxic substances during that period may affect the growth of the brain and behavioral functions."
The study was based on magnetic resonance images showed that some areas in the brain of children is larger than normal because of the insecticide.
The researchers explained that other studies have shown that the rates "chlorpyrifos - ethyl" in urban areas have declined since the United States imposed restrictions on the use of this insecticide, but the danger still exists because of this article used even today in agriculture and golf courses and other
