Peroxyacetyl nitrate is a peroxyacyl nitrate. It is a secondary pollutant present in photochemical smog. It is thermally unstable and decomposes into peroxyethanoyl radicals and nitrogen dioxide gas. It is a lachrymatory substance.

Peroxyacetyl nitrate, or PAN, is an oxidant more stable than ozone. Hence, it is better 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.

The formation of PAN on a secondary scale becomes an issue when ethanol is used as an automotive fuel. Acetaldehyde emissions increase, which subsequently react in the atmosphere to form smog. Whereas ethanol policies solve domestic oil supply problems, they drastically exacerbate air quality conditions.^{[citation needed]}

Athletic performance and urban air pollution.

Shephard RJ.AbstractAir pollution may affect athletic performance. In Los Angeles, contaminants include carbon monoxide, ozone, peroxyacetylnitrate (PAN) and nitrogen oxides, whereas in older European cities, such as Sarajevo, "reducing smog" of sulfur dioxide is the main hazard. The carbon monoxide and ozone levels expected in Los Angeles this summer could affect the athletes' performance in endurance events at the Olympic Games. Carbon monoxide may also impair psychomotor abilities, and PAN causes visual disturbances. The only likely physiologic consequence from reducing smog is an increase in the workload of the respiratory system and thus a decrease in endurance performance. While carbon monoxide has been blamed for myocardial infarctions, nitrogen oxides for pulmonary edema and sulfur dioxide for deaths due to respiratory failure, the only illnesses that are likely to be more frequent than usual among young athletes exposed to high levels of these pollutants are upper respiratory tract infections. Therapeutic tactics include the avoidance of pollution, the administration of oxygen, vitamin C and vitamin E, and general reassurance.
