In a new study of daily ambient fine particulate matter (PM2.5) across the globe, a new study has found that only 0.18% of the global land area and 0.001% of the global population are exposed to levels of PM2.5 — the world’s leading environmental health risk factor — below levels of safety recommended by Word Health Organization (WHO). Importantly while daily levels have reduced in Europe and North America in the two decades to 2019, levels have increased Southern Asia, Australia, New Zealand, Latin America and the Caribbean, with more than 70% of days globally seeing levels above what is safe.
