A subject that could concern us in the Antilles, when we know that the Arc is also faced with air pollution with the current passage of sand mist.

The pollutants studied were fine particles: PM2, PM10, as well as nitrogen dioxide. The research was carried out in urban, peri-urban and rural areas.

The scientists concluded that these pollutants caused epigenetic modifications of the placenta, that is to say by having an impact on the behavior of genes. These disturbances are directly linked to the development of the child, concerning weight, birth size, head circumference or even the duration of the pregnancy.

Nervous and immune system

The study also deals with consequences on the development of the nervous and immune system leading to the occurrence of neonatal diabetes and obesity.

This pollution affects girls and boys differently. First, the placenta is particularly exposed in the first trimester of pregnancy for boys, and in the third trimester for girls. In boys, genes involved in the nervous system and intellect are most affected. In girls, disruption of gene activity increases the risk of “developing chronic metabolic diseases (hypertension, diabetes, obesity, etc.) later in life,” the researchers further indicate.
