What is smog, its types and what are the major impacts of smog
What is smog:
Smog is a type of air pollution caused by a mixture of smoke and fog, typically formed when sunlight reacts with pollutants such as nitrogen oxides (NOₓ) and volatile organic compounds (VOCs) in the atmosphere. The result is a thick, hazy air that can be dangerous to health and the environment.
Two Main Types of Smog:
Photochemical Smog – Found in sunny, urban areas; created by sunlight reacting with vehicle emissions (common in cities like Los Angeles).
Sulfurous Smog (Industrial Smog) – Caused by burning coal and fossil fuels; contains sulfur dioxide (common in older industrial areas).
Major Impacts of Smog:
Human Health:
Respiratory issues (asthma, bronchitis, lung irritation)
Worsening of heart disease.
Eye and throat irritation.
Increased hospital visits and premature deaths.
Environment:
Damage to crops (reduces photosynthesis in plants).
Forest decline.
Soil and water pollution from deposited chemicals.
Visibility and Quality of Life:
Reduced visibility leading to traffic accidents.
Unpleasant outdoor conditions.
Negative impact on tourism and outdoor work.
Buildings and Materials:
Corrosion and damage to buildings, statues, and infrastructure.
Staining of surfaces from acidic particles.
