Pollution occurs when contaminants are introduced into the natural environment. There are several types of pollution including air, water, soil, noise, radioactive, light, and thermal pollution. Air pollution is caused by the combustion of fossil fuels and other emissions releasing gases like carbon dioxide and sulfur dioxide. Water pollution occurs when harmful substances enter water bodies. Soil pollution involves harmful substances mixing into the soil. Noise pollution is mainly an urban issue caused by modernization. Radioactive pollution results from nuclear power plant malfunctions. Light pollution stems from unnecessary outdoor lighting. Thermal pollution contributes to global warming by increasing surface temperatures.

1. POLLUTION
BY: LEO LAURENCE MALLARI

2. •Pollution is the process of making land, water,
air or other parts of the environment dirty and
not safe or suitable to use. This can be done
through the introduction of a contaminant into
a natural environment, but the contaminant
doesn't need to be tangible. Things as simple
as light, sound and temperature can be
considered pollutants when introduced
artificially into an environment.

8. •TYPES OF POLLUTION

9. AIR POLLUTION
Air is the foremost important component of man’s
environment. Causes Of Air Pollution: The combustion
of fossil fuels, biomass, automobile exhaust and many
others have released carbon dioxide, carbon mono
oxide, Sulphur dioxide and also many other
components of toxic gases in the air. Some of the
sources of air pollution are natural and some are made
of pollutants

10. WATER POLLUTION
•Water is one of the basic necessities of life.
Though about three-fourths of the Earth
surface covers with water bodies, but the
availability of fresh water to us is of a serious
issue. Water pollution is another main type of
pollution. It gets polluted when harmful
substances enter the water bodies or seep
down the water table. It has the unique feature

11. SOIL POLLUTION
• Among the many other types of pollution, soil
pollution or land pollution is the next one. Soil is one
of the important natural resources. The soil provides
shelter to many animals and supports the growth of
plants from which we obtain our basic needs. Soil also
gets harmful and polluted when some harmful
substances mix with the soil.

12. NOISE POLLUTION
•Noise causes another means of pollution in our
recent times. This one is mainly an urban
pollution. Due to modernization and
development, there are serious environmental
repercussions. Noise is an unwanted sound in
our environment. This causes adverse effects
on humans.

13. RADIOACTIVE POLLUTION
• One of the most hazardous and dangerous types of
pollutions is radioactive pollution. Radioactive
pollution is caused by a nuclear power plant. Causes
Of Radioactive Pollution: If there is no proper
protection in a a nuclear power plant, or when the
power pants malfunctions, it gives rise to radioactive
pollution. In nuclear power plant, nuclear fission of
radioactive substances is done

14. LIGHT POLLUTION
• This pollution occurs from the unnecessary light in
our surroundings. Unnecessary lights and using more
energy to light up instead of using minimum light
energy for the work need to be done cause light
pollution. Causes Of Light Pollution: Brightening of
sky during nights makes the star and planets visible
by improper lighting

15. THERMAL POLLUTION
• It may also be termed as heat pollution. This mainly
leads to global warming by increasing the temperature
of the Earth’s surface
