Enviromental Pollution II JSS1 Basic Science Lesson Note

ENVIRONMENTAL POLLUTION II

CONSEQUENCES OF POLLUTION

Effects of air pollution

1. It can lead to respiratory diseases (when smoke, soot, and dust are inhaled)
2. Smog can reduce visibility and cause respiratory diseases
3. High concentration of carbon ii) oxide can cause brain damage
4. It can cause cancer

Effects of Soil Pollution

1. Ill health to man and terrestrial animals
2. Stunted growth in plants
3. Barrier to water passage
4. Changes in soil structure
5. Offensive odour

Effects of water pollution

1. Untreated sewage in water causes diseases such as cholera, dysentery, etc.
2. It leads to the death of aquatic animals
3. Offensive odour
4. Oil spillage destroys farmland
5. Pesticides and herbicides make the water poisonous
6. Fertilizers can lead to the overgrowth of aquatic plants, which blocks waterways.
7. Taking in radioactive wastes can bring about genetic mutation

CONTROL MEASURES OF POLLUTION

Control of air pollution

1. Locating industries far from human habitation
2. Educating people on the dangers of air pollution
3. Keeping houses well ventilated
4. Using tall chimneys to discharge waste gases high up in the sky
5. Burning of refuse in incinerators

Control of soil pollution

1. There should be refuse recycling
2. Organic fertilizers should be used effectively, not excessively.
3. The government should create an avenue for proper refuse and sewage disposal

Control of water pollution

1. Proper disposal of sewage
2. Refuses can be buried
3. Oil spillage should be prevented
4. Sewage should be converted into fertilizers
5. Educating the public on the danger of water pollution
6. Fishing with chemicals should be discouraged
7. Oil pipeline vandalism should be curbed.

CLASSWORK 3

1. Highlight three controls of air pollution
2. Enumerate two effects of water pollution
