Photochemical Smog: Rising Challenges

Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight.

Effects and Mitigation of Photochemical Smog

• Photochemical haze has a harmful impact on both the environment and people in a number of ways.
• The molecules produced when the chemicals and hydrocarbons combine to irritate the eyes.
• Because ground-level ozone cannot be eliminated, atmospheric radicals interfere with the nitrogen cycle.
• Ozone has the potential to be extremely ....
