Air pollution … even dangerous for the baby in the mother’s womb!
Spain: A serious study has revealed that if pregnant women are exposed to air pollution, it can affect the development of their unborn child.
Amaya Loibide, a professor at UPV, EHU University at the University of the Basque Country in Spain, has studied air pollution during pregnancy and the amount of Thai Roxin (T4), a type of thyroid hormone in newborns. The heels were pierced 48 hours after birth and blood samples were taken to measure the amount of Thai Roxin.
Extremely fine particles of nitrogen dioxide and two and a half microns (PM2.5) are extremely harmful, especially to the respiratory tract and lungs. That’s why the study noted an increase in thyroxine levels in newborns with nitrogen dioxide. Thyroxine levels were measured weekly in the first pregnant mothers themselves and the baby’s development was also noted (ultrasound and other methods).
A pre-existing database of PM2.5, nitrogen dioxide and other harmful chemicals was also looked at and its information was put forward. It was found that when the mother was exposed to nitrogen dioxide, the balance of thyroid hormone in the baby deteriorated. That is, the amount of thyroxine in children also decreased. Now a lack of this hormone can affect development and brain development.
But experts also say that air pollution, apart from hormones, can affect a child’s development.
