Assessment of the Respiratory Disease Mortality Risk from Single and Composite Exposures to PM_2.5 and Ozone - Guangzhou City, Guangdong Province, China, 2018-2021.

ABSTRACT:

What is already known about this topic?

Fine particulate matter (PM_2.5) and ozone (O₃) are prevalent pollutants in the atmosphere, which threaten human health, especially the respiratory system.
