Effects of pollution
- 3. What kinds of pollution are there?
- 6. Air Pollution Air is very essential in every living being’s life. What is air pollution? The presence of contaminants in the atmosphere which pollutes the air and which can also be injurious to health is known as Air Pollution. How Why A cloud of smoke from the exhaust of a vehicle Increasing traffic Smoke from a factory chimney Growing cities Eruption of a volcano Rapid economic development Cigarette smoke Industrialization Burning leaves Apathetic people
- 7. Types of Air Pollutants Natural Contaminants: Eg: Pollen, Products of volcanic activity, etc. Aerosols: Releases small sized pollutants about 2.5 microns. Vapours & Noxious gases: Chemically react to form smog and acid rain, Eg: Nitrogen oxides, carbon Monoxide ,etc Air Pollutants
- 8. Smog And Acid Rain Smog: Fog mixed with dust and smoke. Formed by chemical reactions between automobile exhaust and pollutants. Occurs when air close to the Earth is cooler than the air above it. Acid Rain: occurs when pollutants like sulphuric acid combines with droplets of water in the air. Defects: Damages vegetation Pollutes the soil Making the land unfit for cultivation Endangering aquatic life.
- 9. Effects of Air Pollution • Health problems • Damage to the environment • Damage to property • Thinning of the protective ozone layer of the atmosphere which is leading to climate changes
- 11. WATER POLLUTION What is water pollution? • Water pollution is the contamination of water bodies. This form of environmental degradation occurs when pollutants like oil, phosphates, bacteria, fungi are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.
- 12. Effects of water pollution • Death of aquatic (water) animals • Diseases Eventually, human beings are affected by this process as well. People can get diseases such as hepatitis by eating seafood that has been poisoned. In many poor nations, there is always an outbreak of cholera and other water borne diseases caused due unsafe potable water. • Devastating to people and animals, fish, and birds. • Unsuitable for drinking, recreation, agriculture, and industry. • Destroys water life.

- 15. What happened to my home?
- 16. • Improper disposal of garbage. • Excess usage of pesticides. • Acid rains • Industrial wastes Radioactive substances Released into the soil • Dumping of sewage and domestic wastes.
- 17. Types of waste • Household waste • Industrial waste • Biomedical or hospital waste Why • Population increases • Increased plastics products • Changes in lifestyle • Landfills not well equipped to protect against contamination
