Lancet Planetary Health study says almost no one is safe from PM2.5
99% of the world's population is exposed PM 2.5 at unhealthy levels according to Lancet Planetary Health's recently released study. The Washington Post author Kasha Patel highlights:
In 2019, they found 0.001 percent of the global population is exposed to levels of PM 2.5 pollution that the World Health Organization deems safe. The agency has said annual concentrations higher than 5 micrograms per cubic meter are hazardous.
Additionally, the study found that across the globe, 70 percent of days in a year were above recommended PM 2.5 levels.
The study describes the knowledge gained from being able to collect data on PM 2.5 daily worldwide. Read the article to learn more about what the results mean for air pollution across the world.
