What does Pan mean in chemistry?

Peroxyacetyl nitrate, or PAN, is an oxidant that is more stable than ozone. Hence, it is more capable of long-range transport than ozone. It serves as a carrier for oxides of nitrogen (NOx) into rural regions and causes ozone formation in the global troposphere.

What is Pan environmental studies?

PAN (Peroxyacytyl nitrate) is a kind of air pollution. It is part of smog. PAN makes people’s eyes hurt and it is bad for your lungs. It also damages plants. PAN forms when some other kinds of chemicals get together in the air.

What is ozone and pan?

Peroxyacetyl nitrate (PAN) and ozone are the two important secondary photochemical air pollutants found in the urban at- mosphere (1-3). the magnitude of primary pollutant emissions and mete- orological parameters such as temperature, mixing volumes, and ventilation rates.

What is structural formula of Pan?

C2H3NO5
Peroxyacetyl nitrate/Formula

Why is pan a secondary pollutant?

PANs are a secondary pollutant since they form in the atmosphere after the emission of primary pollutants. Sources of the pollutants required to create PANs include motor vehicles, tobacco smoke, and the burning of fossil fuels.

How is pan formed?

PAN is formed by oxidation of non-methane volatile organic compounds (NMVOCs) in the presence of NOx. NMVOCs and NOx have both natural and anthropogenic sources. Fossil fuel combustion is the principal NOx source, with additional contributions from biomass burning, light- ning and soils (van der A et al., 2008).

How are PANs produced?

Peroxyacyl nitrates or PANs, which are also referred to as acyl peroxy nitrates or APN, are a component of photochemical smog, produced in the atmosphere when oxidized volatile organic compounds combine with nitrogen dioxide ().

How is a pan formed?

PAN is formed by oxidation of non-methane volatile organic compounds (NMVOCs) in the presence of NOx. NMVOCs and NOx have both natural and anthropogenic sources. The organic side of PAN formation involves many stages of NMVOC oxidation.

What is Pan in zoology?

PAN (Peroxyacytyl nitrate) is a toxic chemical that is an important component of smog. PAN is a gas at normal temperatures and pressures. Its chemical formula is C2H3O5N. PAN molecules are composed of carbon, hydrogen, oxygen, and nitrogen atoms.

What is Pan and what are its effect?

Peroxyacyl nitrates (also known as Acyl peroxy nitrates, APN or PANs) are powerful respiratory and eye irritants present in photochemical smog. They are lachrymators, causing eye irritation at concentrations of only a few parts per billion. At higher concentrations they cause extensive damage to vegetation.
