A recent study from the All India Institute of Medical Sciences (AIIMS) in Delhi highlights the detrimental effects of air pollution on pregnancy and fetal health. The research, published in EMBO Molecular Medicine, indicates that fine particulate matter, specifically PM2.5 and PM10, can breach the placental barrier, leading to inflammation and oxidative stress. This can impair the placenta's ability to supply oxygen and nutrients to the fetus, resulting in complications such as low birth weight and preeclampsia. Animal studies showed that pregnant rats exposed to urban pollution had smaller litters and abnormal placentas, while human data involving 994 pregnancies confirmed that higher exposure to PM2.5 was linked to adverse outcomes. Furthermore, the study identified toxic metals accumulating in placental tissue, which may disrupt fetal growth and neurological development. The findings underscore the urgent need for improved pollution control measures to safeguard maternal and child health, indicating that air pollution poses significant risks beyond respiratory issues.
