There are several major types of pollution that can harm the environment and human health. Air pollution is released directly into the atmosphere from burning fossil fuels and causes issues like acid rain and health problems. Soil pollution results from industrial waste and activities like mining contaminating the ground. Water pollution involves hazardous materials polluting oceans, lakes, and rivers from industry and other sources. Noise pollution is caused by loud vehicles, machines, and music negatively impacting human hearing. Various methods can be used to control and reduce pollution through practices like recycling, reducing waste, and using pollution treatment devices.

2. BURNING TOPIC
• Pollution is the introduction of contaminants into a natural
environment that causes instability, disorder, harm or discomfort to
the ecosystem i.e. physical systems or living organisms.

3. Pollution can take the form
of chemical substances or energy,
such as noise, heat or light.
Pollutants, the components of
pollution, can be either foreign
substances/energies or naturally
occurring contaminants.

4. TYPES OF POLLUTION:-
There are major
following types of
pollution including:
Air Pollution
Water Pollution
Soil Pollution
Noise Pollution

5. Air Pollution
Air pollution is perhaps the most common and the most
dangerous type of pollution. It involves the direct release of
chemicals into the environment.
Causes-
Basically, the air pollution is caused by the burning of fuel
that directly releases hazardous chemicals into the air.
For example, the burning of coal releases sulphur dioxide,
a poisonous gas which is responsible for acid rain.

6. Soil Pollution
Soil pollution involves the contamination of soil by the release of
harmful substances into the soil. Unlike air pollution, which has a
direct affect on human lives
Causes Of Soil Pollution:
Soil pollution is mainly caused by the release of industrial waste.
This waste is directly incorporated into the soil by large industries
and factories. Soil pollution is also caused by human acts as
mining and deforestation etc.

7. Water Pollution
o The 75% of the earth’s surface is covered with water and more that
half of the total population of earth’s species resides in water.
Cause Of Water Pollution
o Just like air and soil pollution, water pollution is caused by the
direct incorporation of hazardous pollutants.
o The sources of these pollutants are yet again the large industries
and factories that dispose off their waste in lakes and ponds.

8. Noise Pollution
o Noise is defined as an unpleasant sound that has an adverse affect
on the human ear.
Cause Of Noise Pollution
o Noise pollution is caused by the moving vehicles, man made
machines and loud music. Other than that noise can be caused by
anything, but these three sources are the main reasons for the noise
pollution around us.

9. POLLUTION CONTROL
Practices
Recycling
Reusing
Reducing
Preventing
Pollution control devices
• Scrubbers
– Baffle spray scrubber
– Cyclonic spray scrubber
– Ejector venturi scrubber
• Industrial wastewater treatment
– API oil-water separators
– Biofilters
– Dissolved air flotation
– Ultrafication systems
