ENVIRONMENTAL POLLUTION II
Consequences of pollution
Control measures of pollution

It can lead to respiratory diseases (when smoke, soot and dust is inhaled)
Smog can reduce visibility and cause respiratory diseases
High concentration of carbon (ii) oxide can cause brain damage
It can cause cancer
Effects of soil pollution
Ill-health to man and terrestrial animals
Stunted growth in plants
Barrier to water passage
Changes in soil structure
Offensive odour
Effects of water pollution
Untreated sewage in water causes diseases such as cholera, dysentery etc.
It leads to the death of aquatic animals
Offensive odour
Oil spillage destroys farm land
Pesticides and herbicides makes the water poisonous
Fertilizers can lead to overgrowth of aquatic plants which blocks water way
Taking in radioactive wastes can bring about genetic mutation
CONTROL MEASURES OF POLLUTION
Control of air pollution
Locating industries far from human habitation
Educating people on the dangers of air pollution
Keeping houses well ventilated
Using tall chimneys to discharge waste gases high up in the sky
Burning of refuse in incinerators
Control of soil pollution
There should be refuse recycling
Organic fertilizers should be used effectively not excessively used
Government should create an avenue for proper refuse and sewage disposal
Control of water pollution
Proper disposal of sewage
Refuses can be buried
Oil spillage should be prevented
Sewage should be converted fertilizers
Educating the public on the danger of water pollution
Fishing with chemicals should be discouraged
Oil pipeline vandalisation should be curbed.
