4. Classification of Pollution
• Sources
– Point Source
– Non Point
• Forms
• Causes
• Pollutants
• Hazardous effects

5. Major types of Pollution
• Air Pollution
• Water Pollution
• Environmental or Soil Pollution
Other types of Pollution
• Noise Pollution
• Radioactive Pollution

6. Air Pollution
• Machinery emits harmful chemicals as wastes.
• Chemicals contains mostly poisonous and toxic
gases
• E.g of air pollutants includes benzene, methane CO
etc.
• The chemical company permits these toxins to be
released without treating them.
• The untreated, toxic chemicals are released directly
into the air and causes different types of effect
spanning from the environment to the human
health.

10. Environmental or Soil Pollution
• Polluting the Environment in diffrent forms
• A good example is a mechanical motor garage
that work on cars accumutaling waste oil on
the soil
• Pollutants are absorbed by plants
• Toxic absorbed chemicals enters the nutrient
cycle, food web, or food chain.

11. Effects of Pollution
1. Environmental Degradation
2. Health Effects
3. Effects on Global Warming
4. Ozone Layer Depletion

12. Environmental Degradation
– Increase in CO, CO2 causes smog
– Smog reduces the sunligh that reaches plants
– Plants cannot process photosynthesis with
reduced Sunlight
– Smog reduces transperancy in water
– Oxides of Sulfur causes Acid rain

13. – Increase in CO, CO2
reduces O2 availability

14. Global Warming Effect of Pollution
• Increase of Earth's average
surface temperature.
• Increases in gaseous
pollutants especially CH4,
Oxides of Nitrogen, CO and
CO2 Increases global warming

15. Effect of Global Warming
• These images show the five-year average variation of global surface
temperatures in 1884, 1927, 1969 and 2012. Dark blue indicates areas
cooler than average. Dark red indicates areas warmer than average.

16. Ozone Layer Depletion Effect
• Ozone Layer is the thin shield high up in the sky
that stops ultra violet rays from reaching the
earth.
• Pollutants such as CFCs, CH4, CO CO2 were
released in to the atmosphere which
contributed to the depletion of ozone layer.

17. Pollution Prevention and Its Social Values
• It means the control of emissions and
effluents into air, water or soil.
• Without pollution control, the waste
products will degrade the enviroment for
the public use.
• Pollution prevention are more desirable
than pollution control in the society

18. Socials Values in Preventing Pollution
• Social Value: is created when resources,
inputs, processes or policies are combined to
generate improvements in the lives of
individuals or society as a whole.
• The following slides will showcase examples of
social values in Preventing pollution

23. Our Recommendations
• Educational programes and awereness advert
on T.V, bilborad etc should increase.
• More researches equating the amout of waste
to substacial values or materials so the lay man
can understand the great demage he his
causing by polluting the environment
• Usage of biodegradable products
• Laws and legistalations against pollution
