Air Pollution: Foul Air May Affect Foetal Heart Development

As per a recent study published in the journal Cardiovascular Toxicology, the cardiovascular system in foetus of the pregnant mothers exposed to particulate matters may get negatively impacted resulting in further consequences throughout the child’s life

Air Pollution: Foul Air May Affect Foetal Heart Development

New York: Pregnant mothers exposed to particulate matters may experience damage to the developing cardiovascular system in their foetuses, finds a study. Exposures to these microscopic materials early in the gestation period significantly impact foetal heart development, especially the main artery and the umbilical vein. A single exposure during the third trimester could restrict maternal and foetal blood flow, resulting in further consequences throughout the child’s adulthood, the study said.

Late exposures mostly impact the foetal size as it restricts blood flow from the mother and deprives the foetus of nutrients in the final stages. Phoebe Stapleton, Assistant Professor at Rutgers University said,

Pregnant women should also consider monitoring their indoor air quality.

What a mother inhales affects her circulatory system, which is constantly adapting to supply adequate blood flow to the foetus as it grows. Ms. Stapleton said,

These findings suggest that pregnant women, women of child-bearing age and those undergoing fertility treatments should avoid areas with high air pollution or stay indoors on high-smog days.

Air pollution exposure constricts blood vessels, restricts blood flow to the uterus and deprives the foetus of oxygen and nutrients, resulting in delayed growth and development. It can also lead to common pregnancy complications, such as intrauterine growth restriction, she explained.

The study, published in the journal Cardiovascular Toxicology, looked at how the circulatory systems of pregnant rats’ foetuses on a single exposure to nanosized titanium dioxide aerosols – a surrogate for particles found in typical air pollution – during their first, second and third trimesters.

The results were compared to pregnant rats that were exposed to high-efficiency filtered air. In non-pregnant animals, even a single exposure to these nanoparticles was linked to the impaired function of the arteries in the uterus.

Helmed by Campaign Ambassador Amitabh Bachchan, the campaign aims to spread awareness about hygiene and sanitation, the importance of building toilets and making India open defecation free (ODF) by October 2019, a target set by Prime Minister Narendra Modi, when he launched Swachh Bharat Abhiyan in 2014. Over the years, the campaign has widened its scope to cover issues like air pollutionwaste managementplastic banmanual scavenging and menstrual hygiene. The campaign has also focused extensively on marine pollutionclean Ganga Project and rejuvenation of Yamuna, two of India’s major river bodies.
