Surprisingly, the typical drivers of ozone formation—sunlight and warmth—played minimal roles. Instead, chemical reactions involving alkenes—particularly their ozonolysis—emerged as the ...

In densely populated coastal areas, reactions of polluted air with sea salt aerosol from the ocean can lead to high surface ozone levels that affect air quality. Chlorine has become infamous for ...

The researchers studied heart attack occurrence alongside concurrent levels of ozone and PM2.5 (airborne particles with a diameter of 2.5 micrometers or smaller) near the patients' homes.

The overall research goals are to quantify the emissions of primary pollutants and elucidate the formation mechanisms of secondary pollutants, especially ozone (O 3) and secondary aerosol. Much of ...

Rainfall triggers bursts of natural nanoparticles, which contribute to cloud formation and additional precipitation over the ...

Get Instant Summarized Text (Gist) Increases in methane emissions could significantly impact the recovery of the stratospheric ozone layer, especially in polar regions. Methane, while a potent ...

Ozone season is upon North Texas, meaning air quality will be top of mind for some residents. The season — which marks the window when there’s a greater risk of harmful amounts of ground-level ...
