In a comprehensive global study spanning nearly two decades, researchers have revealed the staggering toll of short-term exposure to fine particulate matter (PM2.5) on human health.
Drawing from extensive data on PM2.5 concentrations, population figures, mortality rates, and exposure-response functions, the researchers estimated that approximately 1 million premature deaths annually between 2000 and 2019 can be attributed to short-term PM2.5 exposure. This grim statistic represents over 2% of total global deaths or 17 premature deaths per 100,000 individuals each year.
Moreover, the study identified urban areas as particularly vulnerable, with around 0.23 million deaths annually attributable to short-term PM2.5 exposure, accounting for over 20% of total global deaths linked to this cause. Asia and Africa bore the brunt of this burden, 65.2% and 17% respectively, highlighting the urgent need for mitigation strategies in these regions.
The robustness of these findings was confirmed through sensitivity analyses, reaffirming the severity of the global mortality burden associated with short-term PM2.5 exposure.
Air pollution continues to be a major contributor of morbidity and mortality around the world. There are absolutely no excuses from governments and industries to delay action on mitigating pollution output. The absolute danger from the lack of prioritizing transitioning to clean solutions comes from the fact that often pollution is not felt or seen like war or it’s apparentness is very fleeting despite that it is present all the time.
There are no solutions from the healthcare nor pharmaceutical sectors that can counter act the immense harm created by the industrial sectors, and the solution must be tackled at the roots.
