Toxicity of Peroxyacetyl Nitrate on Human

In recent years, air pollution has been a major threat due to photochemical smog in china, which continuously increases the concentration of photochemical pollutants. Pan is formed by the reaction of nitrogen oxides and hydrocarbon under action of light. Nitrogen dioxides comes from engines of trucks and cars and from power plants that burn coal. It enables passage and release of NOx to the remote troposphere which cause distribution of ozone and OH, main tropospheric oxidants. Pan is secondary pollutants. The toxicity of ozone is more than acute toxicity of pan but pan toxicity is similar to NO₂ and higher than SO₂.Damage to epithelium of respiratory tract and severe lung problems were seen in animals. The pan concentration is well above the maximum ambient concentration. Present ambient concentration would affect pulmonary functions. Lowest level causing eye irritation in human. This review will be helpful to understand the PAN toxicity and also would be capable to minimize the PAN toxicity.
