Toward Better and Healthier Air Quality: Global PM_2.5 and O₃ Pollution Status and Risk Assessment Based on the New WHO Air Quality Guidelines for 2021.

ABSTRACT: To reduce the high burden of disease caused by air pollution, the World Health Organization (WHO) released new Air Quality Guidelines (AQG) on September 22, 2021. In this study, the daily fine particulate matter (PM_2.5) and surface ozone (O₃) data of 618 cities around the world is collected from 2019 to 2022. Based on the new AQG, the number of attainment days for daily average concentrations of PM_2.5 (≤ 15 µg m^-3) and O₃ (≤ 100 µg m^-3) is approximately 10% and 90%, respectively. China and India exhibit a decreasing trend in the number of highly polluted days (> 75 µg m^-3) for PM. Every year over 68% and 27% of cities in the world are exposed to harmful PM_2.5 (> 35 µg m^-3) and O₃ (
