📚 Understanding Smog and Air Pollution
What is Smog?
Smog is a type of air pollution that occurs when smoke and fog combine with other atmospheric pollutants. The term was first coined in 1905 to describe the smoky fog conditions in London.
Key Components:
- • Particulate Matter (PM2.5, PM10): Tiny particles that penetrate deep into lungs
- • Benzo[a]pyrene: Highly carcinogenic compound from burning fossil fuels
- • Nitrogen Oxides (NO₂): Primarily from vehicle emissions
- • Sulfur Oxides (SO₂): From industrial processes and coal burning
- • Ozone (O₃): Forms through photochemical reactions
Types of Smog
London-Type Smog ❄️
Winter smog in temperate zones, primarily from coal burning and industrial emissions. Contains high levels of particulates and sulfur compounds.
Los Angeles-Type Smog ☀️
Summer photochemical smog in sunny climates, formed when vehicle emissions react with sunlight to create ozone and other compounds.
Health Impact
Air pollution causes 4.2 million premature deaths annually worldwide, contributing to respiratory diseases, cardiovascular problems, and cancer.
