Study Notes
Air and Water Pollution
- Air and water are essential for life
- Pollution is the unwanted and harmful changes in the environment
- Pollution can be caused by physical, chemical, or biological factors
- Pollution harms both living and non-living things
- Air pollution is a significant problem in urban and rural areas
Types of Air Pollution
- Primary Pollutants: Substances emitted directly into the air from sources
- Examples include volcanic ash, smoke from burning coal, and carbon monoxide and dioxide
- Secondary Pollutants: Result from the interaction of primary pollutants with other substances in the atmosphere
- Examples of secondary pollutants are formed when sulfur dioxide reacts with air to produce sulfuric acid
- Based on Source:
- Industrial emissions
- Vehicle exhaust
- Burning of fossil fuels
- Agricultural activities
- Based on the Form of Pollutant:
- Gases
- Particulate matter
- Chemicals
Air Composition
- Air is a mixture of gases, including oxygen, carbon dioxide, nitrogen, and others
- The proportions of these gases in the atmosphere are mostly stable
