This document discusses the three main types of pollution: air pollution, water pollution, and land pollution. It provides information on the sources and effects of each type. Air pollution results from outdoor sources like insecticides and herbicides as well as indoor sources like pollen and mold. It harms human health and the environment by causing issues like acid rain, ozone depletion, and global warming. Water pollution changes water quality and harms ecosystems, wildlife, and humans. It can come from point sources like discharge or nonpoint sources like agriculture. Land pollution degrades the earth's surface from improper waste disposal, mineral exploitation, and agriculture, harming wildlife and vegetation.

2. Air Pollution
o What is air pollution :
contamination of the air by noxious gases
and minute particles of solid and liquid
matter (particulates) in concentrations that
endanger health

3. Air Pollution
o Sources of Outside Air Pollution
1- Insecticides 3- Livestock feedlots
2- Herbicides 4 - Everyday radioactive fallouts
o Sources of Indoor pollution
1- pollen 3- Molds and mildews
2- house dust 4- animal dander and cat saliva

4. Air Pollution
o Effects on the environment
1- Acid rain
2- Ozone depletion
3- Global warming
4- In human population- respiratory
problems, allergies, strengthens lugs, and a risk
for cancer

5. Air Pollution

6. Water Pollution
Water pollution is any chemical, physical or
biological change in the quality of water
that has a harmful effect on any living thing
that drinks or uses or lives (in) it. When
humans drink polluted water it often has
serious effects on their health. Water
pollution can also make water unsuited for
the desired use.

7. Water Pollution
o Point sources
1- Discharge at specific locations
2- Easier to identify, monitor, regulate
o Nonpoint sources
1- Agriculture
2-Runoff of chemicals and sediment

8. Water Pollution
o Effects on the environment
1- Spread of disease
2- Flooding
3- Harms the food chain
4- Harms animals

9. Water pollution

10. Land pollution
Land pollution is the degradation of Earth's
land surfaces often caused by human activities
and their misuse of land resources. It occurs
when waste is not disposed properly. Health
hazard disposal of urban and industrial
wastes, exploitation of minerals, and improper
use of soil by inadequate agricultural practices
are a few factors

11. Land pollution
o Causes of land pollution
1- Increase in urbanization
2- Increase in agricultural land
3- Domestic waste
4- Agricultural activities
5- Industrial activities

12. Land pollution
o Effects on the environment
1- exterminates wildlife
2- acid rain kills trees and other plants.
3- vegetation that provides food and
shelter is destroyed.
