A study carried out by Peking University in China with 80 newborns and fetuses from abortions in which brain and spinal cord failures were recorded (neutral tube defects) has shown that women who are in contact with pregnancy during pregnancy pesticides or chemicals from the combustion of coal have up to three and 4.5 times, respectively, more likely to give birth to babies with serious birth defects, compared to those who have not been exposed to these substances.

The authors of the research detected in the placentas of women who had had babies with congenital malformations very high levels of Polycyclic aromatic hydrocarbons (HAP), coming from inhaling pesticides and burning coal smoke. Tong Zhu, one of the authors of the study, explained that this type of pollutant is able to easily transfer pre-placental structures and causes a potential impact on the development of the embryo.

Babies of pregnant women who have been exposed to pesticides have three times the risk of suffering neural tube defects, which have been to carbon smoke, 4.5 times more than the rest

The so-called neural tube defects (ie, those related to the brain and spinal cord), such as spina bifida or anencephaly, are more frequent than previously thought, since they occur in approximately six out of every 10,000 births. alive in the world.

One of its most common forms is when the spine does not close completely in the first month of gestation, which causes nerve damage to paralysis in the legs. If the end of the tube does not close as it should, the brain remains undeveloped, so that babies are usually born dead or do so shortly after delivery.

Avoid exposure to coal smoke, use cleaner systems for cooking or heating the environment are some of the most recommended preventive measures. On the other hand, eating a balanced diet rich in folic acid can also help prevent these types of complications.
