Mitigation of the ozone-pollution problem is complicated by the fact that ozone (O 3) is a secondary pollutant; that is, it is not emitted directly into the atmosphere, but is produced by ...

Atmospheric ozone, which can regulate the amount of incoming ultraviolet radiation on the Earth's surface, is important for the atmospheric environment and ecosystems. Tropospheric ozone, primarily ...

Observational Constraints Reveal Biases in OVOC-Driven Radical Chemistry. Schematic illustration of how limited OVOC constraints bias simulations of radical (ROₓ) chemistry and ozone formation. When ...

As a result of work on the photochemical chlorine-ozone reaction carried out at King's College, London, 1 experiments have been in progress on the bromine-ozone reaction in the hope of explaining the ...

We know the recent extreme heat is something that we can expect more of as a result of increasing temperatures due to climate change. But a new study warns that there's another impact -- worsened air ...

Despite decades of progress in reducing air pollution, Los Angeles is still the nation's smoggiest city, according to a report released on April 23 by the American Lung Assn. A new study has revealed ...

Researchers have discovered why reducing particle pollution is leading to a rise in photochemical smog in some emerging economies such as India, Africa and China. Researchers from the University of ...
