Understanding Air Pollution

Industrial pollution

Introduction

Air pollution is one of the most pressing environmental issues affecting human health, ecosystems, and climate change. This comprehensive guide explains its causes, effects, and solutions.

Types of Air Pollutants

Primary Pollutants

  • Carbon monoxide (CO) from vehicles
  • Sulfur dioxide (SO₂) from factories
  • Nitrogen oxides (NOₓ) from combustion
  • Particulate matter (PM) from construction

Secondary Pollutants

  • Ground-level ozone (O₃)
  • Acid rain from SO₂/NOₓ
  • Smog from chemical reactions

Major Causes

Factory

Industrial Emissions

Factories release CO, SO₂, and NOₓ contributing to smog

Traffic

Vehicle Exhaust

Cars and trucks emit CO and NOₓ

Deforestation

Deforestation

Reduces CO₂ absorption capacity
