which has made up of Smoke and Fog.<\/strong><\/li>\n\n\n\n<li>Photochemical smog, also known as&nbsp;<strong>summer smog<\/strong>, is a type of smog that is&nbsp;<strong>produced when UV light originating from the sun interacts with the oxides of nitrogen present in the atmosphere<\/strong>.\n<ul class=\"wp-block-list\">\n<li>This type of smog usually manifests as a brown haze and is most commonly seen in highly populated cities that are placed in relatively warm climates.<\/li>\n\n\n\n<li>Furthermore, photochemical smog is most prominently visible during the mornings and afternoons.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Traditionally, the smog has resulted from large amounts of coal burning in an area&nbsp;<strong>caused by a mixture of smoke and sulfur dioxide<\/strong>.<\/li>\n\n\n\n<li>Nowadays, the Vehicle emissions and Industrial emissions that are acted on in the atmosphere by ultraviolet light from the sun to form secondary pollutants that also combine with the primary emissions to form photochemical smog.<\/li>\n\n\n\n<li>The major chemical pollutants in&nbsp;<strong>Photochemical smog are NO, NO<sub>2<\/sub>, volatile organic compounds, Ozone,&nbsp;and PAN (Peroxyacetyl Nitrate)<\/strong>.\n<ul class=\"wp-block-list\">\n<li><strong>NO<sub>2<\/sub>&nbsp;decreases visibility due to yellowish
