Researchers have linked low IQ levels in children to poor environment for the first time.

Urban smog can seriously harm a child's brain development. American scientists came to this conclusion. The study involved 249 New York women who wore special sensors that detect the presence of harmful substances in the atmosphere during the last few months of pregnancy.

Most women lived on the outskirts of the city in North Manhattan or the South Bronx and were regularly exposed to environmental hazards typical of the city, mainly from car, bus and truck exhausts.

When these women's children were 5 years old and had to go to school, they were asked to take an IQ test. As a result, those children who were in a more harmful ecological environment even before birth had a level of intellectual development that was 4-5 points lower than that of their peers.

"That's a big enough difference that it could affect these kids' success in school," says Frederica Pereira, author of the study.

Researchers have studied sources of pollution that can have a negative impact on a child's development. They turned out to be vehicle exhaust and factory emissions.
