Ozone pollution around a coastal region of South China Sea: interaction between marine and continental air [PDF]

Atmospheric Chemistry and Physics, 2018
Marine atmosphere is usually considered to be a clean environment, but this study indicates that the near-coast waters of the South China Sea (SCS) suffer from even worse air quality than coastal cities.

Short-term exposure to wildfire-related PM2.5 increases mortality risks and burdens in Brazil

Nature Communications, 2022
To assess mortality risks and burdens associated with short-term exposure to wildfire-related PM2.5, the authors collect daily mortality data from 2000 to 2016 for 510 immediate regions in Brazil, the most wildfire-prone area.
