Researchers from the University of York have discovered why reducing particle pollution is actually increasing surface ozone pollution in some emerging economies, negatively impacting health, ...

Diazo compounds, characterised by a diazo functional group (–N₂), serve as versatile precursors to carbenes upon exposure to light. Photochemical activation of these species enables clean N₂ extrusion ...

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 ...

Surface ozone levels are expected to be high in polluted regions during summer months. Observations from Wyoming in February 2008 indicate that equally high concentrations of ozone can be produced ...

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 ...
