The research highlights the severe health impacts of air pollution and underscores the urgent need for interdisciplinary research and evidence-based interventions to mitigate these effects, particularly in vulnerable populations and low- and middle-income countries.
By Dr. Sanchari Sinha Dutta, Ph.D.Jul 28 2024 In a review article published in the journal Science, the authors discuss the health effects of air pollution and challenges associated with monitoring population exposure to air pollution , particularly in low—and middle-income countries and among vulnerable populations.
Non-communicable diseases are associated with a significant percentage of global mortality and disability, accounting for almost 41 million deaths per year, with 77% occurring in low- and middle-income countries. About 99% of the global population is continuously exposed to poor-quality air that exceeds the AQG limits. Populations with increased vulnerability due to age, sex, and disease status are at higher risk from the damaging effects of air pollution exposure.
Currently, most countries worldwide routinely monitor ambient air pollution for regulatory purposes. Although levels of PM and ozone have decreased in high-income countries in recent times, air pollution exposure levels remain high in many countries, especially in South Asia.

Ultrafine particles are associated with severe health adversities as they can enter deep into the lung, translocate into the systemic circulation, and subsequently reach the brain.
