NEW DELHI: In a pioneering scientific development, researchers at the All India Institute of Medical Sciences (AIIMS), Delhi, have unveiled precisely how ambient air pollution, particularly fine particulate matter ($PM_{2.5}), physically targets and damages developing foetuses.

While medical consensus has long associated toxic air quality with adverse pregnancy outcomes, this breakthrough study maps the exact cellular and biological pathways, showing how these microscopic particles cross crucial maternal-foetal barriers to disrupt intrauterine growth.

particles bypass the respiratory filtering mechanisms, invading her bloodstream. Once in the circulatory system, these microscopic toxins migrate directly to the placenta the vital organ responsible for supplying oxygen and essential nutrients from the mother to the baby triggering localized tissue inflammation, oxidative stress, and blood coagulation.
