Photochemical smog is formed when nitrogen oxides and volatile organic compounds react to sunlight, producing harmful pollutants like ozone and PAN.
Essential requirements for the formation of photochemical smog include nitrogen oxides (NOx) and volatile organic compounds (VOCs) reacting to sunlight, resulting in the creation of powerful oxidants like ozone and peroxyacetyl nitrate (PAN). This process leads to the formation of photochemical smog, which is harmful to both plant life and human health.
