According to the latest research, babies in the womb can get affected with the environmental pollution, researchers portended. Scientist found the level of pollution exposure of mother, especially in first and last trimester, is directly proportional to the birth weight of the baby

The data of 336,000 babies showed the trend, which were born in the New Jersey in the period of 1999 to 2003. More research is needed to explain the connection.

Researchers also analyzed the complete history of the mother on the basis of factors such as smoking, marital status, race, education, and the place where they spent their gestation period.

Researcher noted the level of pollution in the surrounding area in the all three trimester of pregnancy. They found the mothers of underweight babies were relatively younger, less educated, smoker or African-American.

But above all of these factors pollutants suspended in the air limit the foetal growth in the womb. The two pollutants, micro sooty particles and nitrogen dioxide emitted in the car smoke, were found guilty for inhibiting the feotal growth in the womb.

Even with the fractional increase of nitrogen dioxide in the air, in which mother breath, can increase the risk of low birth weight baby.

“These findings suggest that car’s smoke can affect the fetal growth and those pregnant women who live near to the roadway are on greater risk,” lead researcher Professor David Rich said.
