Of lead paint is the largest source of pollution

United States researchers study published on 27th results said, a person in the fetal or childhood lead contamination, suffered permanent brain damage, adult criminal actions that might arise.

The conclusion from two study on lead pollution and its effects on brain injury. Research published in the journal public library of Science Medicine.

United States Jin·ditelixi of the University of Cincinnati, Ohio, said lead pollution and crime, and even United States town centre crime in many cities of the culprit, because most downtown old house using lead-containing coatings paint job.

From 1979 to 1984, Dietrich and his colleagues recruited 250 living in Cincinnati lead contaminated pregnant women participating in the home. Their testing of pregnant women and their newborn infants blood lead concentration and growth of newborn follow-up.

In the study, they put the child\'s blood lead concentrations associated with its adult criminal records and discovered, from the prenatal period to higher childhood blood lead concentrations of people illegal and more. Respondents of the research group of Dietrich, 55% at least one illegal record, 28% personal depression and drug-related crime, 27% who has a serious traffic violation.

Blood lead damages brain cells

Research shows that high childhood blood lead concentrations of people grew up part of the brain cell is missing, so the more the tendency for crime, particularly violent crime.

Use of magnetic resonance imaging technology, Cincinnati Children\'s medical center of Dr Jin·saixier with Dietrich on the targets of brain scans. They found that these people lack of brain gray matter by 1% or more.

Cecil\'s research report wrote: \"most seriously affected parts including the prefrontal gray matter, specifically is the anterior Cingulate Cortex. \"This region is a region of the brain responsible for emotion and judgment. Study finds that effects men than women are more vulnerable to loss of brain gray matter.

Research also shows that this structural change will be persisted. Dietrich said: \"the impact of serious, irreversible because most cases of lead poisoning injuries. ”

Of lead paint is the largest source of pollution

Dietrich said that as of now, the lead containing lead paint is the largest source of pollution. In the object of investigation, from childhood, mothers are likely to suffer from lead contamination, high lead content in the body. Then, when their pregnancy, abdominal fetuses will be in lead pollution. Also, most of these children still grew up in a home in those contaminated by lead.

Dietrich believes that, subject to environmental constraints, low-income families and children are more vulnerable to lead pollution in the city centre. Downtown old house used often with lead paint, lead greater impact on the crime rate in these areas. He said: \"some data show that in the past decades, affecting the same proportionate to the crime rate of lead. ”

He said: \"despite much progress has been made in reducing lead pollution, but research shows that people should make greater efforts to reduce child lead pollution, this may be important in curbing violent crime and implementation methods. ”
