City lights make air pollution worse
(PhysOrg.com) -- A new study by scientists in Los Angeles, California has found that bright city lights makes air pollution worse because the glare of the lights interferes with chemical reactions that clean ...
Switching from coal to natural gas would do little for global climate, study indicates
Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. The study appears ...

Nitrogen oxide
The term nitrogen oxide typically refers to any binary compound of oxygen and nitrogen, or to a mixture of such compounds:
(Note that the last three are unstable.)
Chemical reactions that produce nitrogen oxides often produce several different compounds, the proportions of which depend on the specific reaction and conditions. For this reason, secondary[clarification needed] production of N2O is undesirable, as NO and NO2 — which are extremely toxic — are liable to be produced as well.
