 What are the different types of pollution?
There are a few types of pollutions known to man and they are, air pollution, land pollution, water pollution, thermal pollution, noise pollution, personal pollution, light pollution, visual pollution and radioactive pollution but mainly air pollution, land pollution, water pollution, thermal pollution, noise pollution and radioactive pollution results in a large impact on animal and human life.

Air pollution is caused when harmful gases or small particles are released into the environment, causing detrimental health effects. When such gases or particles are inhaled by human, their health will be affected, showing signs of medical damage. Gases such as sulfur dioxide and nitrogen oxides not only pollutes the air but also causes acid rain which harms the environment even further. While gases such as carbon monoxide and methane causes global warming by excess greenhouse effect.

Land pollution refers to the pollution of soil which renders it useless for sustaining natural growth, be it for animals or plants. Land pollution is either caused deliberately or by accident for example landfills which is deliberate and sewage and toxic spill which are by accident.

Water pollution occurs when foreign harmful substances enter a clean source of water, reducing its purity and quality. An example of such would be fecal pollution where the water source is contaminated with disease carrying organisms which causes many diseases to the human who drinks the water, and as different water sources flow together, pollution can spread very quickly.

Thermal pollution is excess heat which generates negative effects for a long period of time. Power plants and factories produce heat in a large amount which is released to the environment, this causes the surrounding temperature to increase by a bit which accumulates to a large amount of heat in due time. This large amount of heat accumulated also contributes to global warming which is deadly to the whole of humanity.

Noise pollution is the high level of noise produced by a source which is not needed and not wanted. Noise sources are usually caused by human activity such as traffic, constructions and railroads. This may in time cause induced hearing loss and wildlife disturbance, causing a general impact on our lifestyle.

Radioactive pollution rarely occurs, but it is very deadly and difficult to remedy. It is usually caused from nuclear power plant accidental leakage or improper nuclear waste disposal. Radioactive pollution can cause birth defects, cancer and other health problems for human and wildlife populations. It can also pollute the soil and contribute to water and air pollution.
Pollutants?

Pollutants are mainly inorganic compounds, organic compounds, microorganisms and gaseous compounds. For example metals such as copper and lead, petrochemicals, Escherichia Coli and sulfur dioxide and methane.
