Nitrous acid (HNO 2) is an unstable weak acid. It cannot be isolated and is known only in aqueous solution and in the gas phase. In both media, it disproportionates: in solution, to nitric oxide, ...

Heterogeneous chemistry of atmospheric nitrous acid (HONO) encompasses the set of processes occurring at the interface of gas phase and condensed matter—surfaces, aerosols and ground substrates—that ...

Atmospheric nitrous acid (HONO) is an important source of tropospheric hydroxyl radicals (OH). During daytime, sunlight turns HONO into hydroxyl radicals. This process may make up as high as 60% of ...

Researchers have found that one method of reducing greenhouse gas emissions is available, affordable, and capable of being implemented right now. Nitrous oxide, a potent greenhouse gas and ...

The high-quality development of a country cannot be separated from environmental protection and improving water use efficiency, among which sustainable wastewater management plays an important role.

A dump truck drives up a road in an open pit mine. The Fimiston Open Pit in Australia’s Goldfields–Esperance region produces roughly 24,000 kg of gold per year. Metal mining uses large amounts of ...

Ozone pollution is a global environmental concern that not only threatens human health and crop production, but also worsens global warming. While the formation of ozone is often attributed to ...
