This document discusses various types of environmental pollution including air, noise, light, land, thermal, plastic, and water pollution. It outlines the causes and sources of different types of pollution as well as their effects such as global warming, ocean acidification, smog formation, and damage to ecosystems. The document also presents some control measures that can help mitigate pollution like recycling, waste minimization, and using environmentally friendly products. In conclusion, it states that pollution is one of the largest global public health issues, affecting over 100 million people each year and that plastic pollution is a major problem with over 1 trillion plastic bags used worldwide annually.

3. Pollution is the introduction of
contaminants into the natural
environment that cause adverse change
Pollution started from prehistoric times
when man created the first fires.

4. Types
Air pollution
Noise pollution
Light pollution
Land pollution
Thermal pollution
Plastic pollution
Water pollution
Radioactive pollution

5. Air Pollution
Release of chemicals and particulates
into the atmosphere.
Pollutants produced by industry and
motor vehicles.
carbon monoxide, sulphur
dioxide, chlorofluorocarbons (CFCs)
and nitrogen oxides
.
.

6. Noise Pollution
roadway noise, aircraft noise, industrial noise

7. Light Pollution
light trespass
over illumination
astronomical interference

8. Land Pollution
Chemicals are
released by spill or
underground leakage
Hydrocarbons
Heavy metals
Herbicides
Pesticides

9. Thermal Pollution
temperature change in natural bodies caused by human
influence

10. Plastic Pollution
Accumulation of plastic products in the
environment that adversely affects wildlife,
wildlife habitat, humans

11. Water Pollution
Discharge of waste waters from commercial and industries into water sources
Discharges of untreated domestic sewage and chemical contaminants
Leaching into ground water eutrophication and littering.

12. Radioactive Pollution
nuclear power generation
nuclear weapons research
manufacture and deployment

14. EFFECTS
• Biomagnification
passing of heavy metals
through trophic levels.
• Ocean acidification
Carbon dioxide emissions
decrease the pH of the
Earth's oceans
• Global warming
The emission of
greenhouse gases affects
ecosystems
• Smog and haze can reduce
the amount of sunlight
received by plant to carry
photosynthesis which
damages plants.
• Soil can become infertile
• Acid rain

15. Recycling
Reusing
Waste minimisation
Mitigating
Preventing
Compost
PREVENTIVE MEASURES

16. Conclusion
Caused by contamination of pollutants
Pollution is one of the biggest global killers,
affecting over 100 million people.
Over one trillion plastic bags are used each year
around the world.
Use environmentally friendly products.
