High blood lead levels can easily harm the brain of children

Recent research by American scientists shows that high levels of lead in the blood can damage children's brains and make them more prone to violence when they grow up.

Researchers at the University of Cincinnati recently published a paper in the online edition of the American Journal of Public Scientific Library Medicine that the damage to children's brains caused by excessive levels of lead in the blood is "permanent," and that such damage may make children grow long. After the big, I am impulsive and commit crimes.

The report said that researchers selected 376 pregnant women in the city of Cincinnati to test their blood for lead levels. When the child was born, the researchers followed the blood lead levels of these children until they were 7 years old. When these children grow up, the researchers go to investigate the current state of their lives.

It was found that 55% of children who had high blood lead levels in childhood had been arrested for misconduct. This proportion is much higher than normal.

Experts believe that the high level of lead in children's blood is mainly due to pollution of the living environment, such as contact with colored toys with high lead content in pigments, printed matter, crayons, or consumption of fruits and vegetables contaminated with lead-containing pesticides.
