Types of Pollution
Air Pollution

Air pollution occurs when gases, dust particles, fumes (or smoke) or odour are introduced into the atmosphere in a way that makes it harmful to humans, animals and plant. This is because the air becomes dirty (contaminated or unclean).

Causes: Partially combusted exhaust gases released from internal combustion engines add poisonous gases into the atmosphere.

Effects: Air pollutants can be in the form of particulate matter which can be very harmful to our health.

Noise Pollution

There are different qualities of sounds. The sounds which are not pleasant to hear are called ‘Noises’. So an excess of noise in the outdoors leads to “Noise Pollution”.

Causes: Some cause are; too many vehicles honking on the roads, heavy machinery being operated in the open; jackhammers, trains, clubs, over populated crowds and many more.

Effects: Noise pollution is known to cause mental stress and depression. It can also cause damage to the ear drum which can cause deafness.

Land pollution

Land pollution is the contamination and deterioration of the earth’s land surfaces, often directly or indirectly as a result of man’s activities and their misuse of land resources.

Causes: Improper disposal of waste

Effects: Causes problems to the human respiratory system

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.

Causes: Dumping solid wastes and littering by humans in rivers, lakes and oceans.

Effects: Water pollution causes flooding due to the accumulation of solid waste and soil erosion in streams and rivers.
