This document discusses the different types of environmental pollution: air, water, soil, noise, thermal, and radioactive. It defines each type of pollution, discusses their causes, and provides examples of their negative impacts on the environment and human health. The document also suggests some methods to reduce each type of pollution, such as using public transit and renewable energy to improve air quality, proper waste management and sewage treatment to protect water sources, and reducing pesticide and fertilizer use to prevent soil contamination. The overarching message is that pollution poses serious threats but concerted efforts are being made to address the problems.

2. ENVIRONMENTAL POLLUTION
 INTRODUCTION
 DEFINITION & CAUSES
 TYPES:
1.AIR POLLUTION
2.WATER POLLUTION
3.SOIL POLLUTION
4.NOISE POLLUTION
5.THERMAL POLLUTION
6.RADIOACTIVE POLLUTION.

3. INTRODUCTION
 Pollution is the introduction of contaminants into the natural
environment that cause adverse change.
 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.
 The combustion of fossil fuels pollutes the air, the soil and the
water with noxious gases such as CO2 and CO. Agricultural
waste: Fertilizers and pesticides used in agriculture are
key causes of environmental pollution.

4. DEFINITION & CAUSES
 Pollution is the contamination of the environment by
introduction of contaminants that can cause damage
to environment and harm or discomfort to humans or other
living species.
 Smokes from the industries, house chimneys, vehicles, and
fuels causes air pollution. Wasted industrial solvents, plastics,
and other wastes, sewage etc., causes water pollution. Use of
pesticides and deforestation are the major causes of
soil pollution.

5. AIR POLLUTION Air pollution is a mixture of natural and man-made substances
in the air we breathe.
 Air pollution is caused by solid and liquid particles and certain
gases that are suspended in the air. These particles and gases
can come from car and truck exhaust, factories, dust, pollen,
mold spores, volcanoes and wildfires.
 High levels of air pollution can cause an increased risk of heart
attack, wheezing, coughing, and breathing problems, and
irritation of the eyes, nose, and throat. Air pollution can also
cause worsening of existing heart problems, asthma, and other
lung complications
 Air pollution can be significantly reduced by expanding access
to clean household fuels and technologies, as well as
prioritizing: rapid urban transit, walking and cycling networks;
energy-efficient buildings and urban design; improved waste
management; and electricity production from renewable power
sources.

6. WATER POLLUTION
 Water pollution is the contamination of water bodies, usually as a result of
human activities. Water bodies include for example lakes, rivers, oceans,
aquifers and groundwater. Water pollution results when contaminants are
introduced into the natural environment.
 Domestic sewage- These wastes are generated from household activities.
Industrial wastewater- These are wastewater generated through industrial
processing. Agricultural waste- These include pesticide, chemical fertilizer,
manure, etc. Acid rain.
 Water pollution may not damage our health immediately but can be harmful
after long term exposure. Different forms of pollutants affect the health
of animals in different ways Microbial pollutants from sewage often result
in infectious diseases that infect aquatic life and terrestrial life through
drinking water.
 Ensure minimal use of bleach or detergents, Reduce the use of herbicides,
pesticides, and fertilizers, Proper sewage treatment and management.

7. SOIL POLLUTION
 Soil pollution is defined as the buildup in soils of persistent toxic
compounds, chemicals, salts, radioactive materials, or disease-causing
agents, which have adverse effects on plant growth and animal health.
 Industrial waste,Deforestation, Excessive use of fertilisers and
pesticides,Garbage pollution,Climate change,Loss of soil
fertility,deforestation.
 soil pollution increase the salinity of the soil making it unfit for vegetation,
thus making it useless and barren. Soil pollution can have a number
of harmful effects on ecosystems and human, plants and animal health.
... Soil pollution can also cause neuromuscular blockage as well as
depression of the central nervous system, headaches, nausea, fatigue, eye
irritation and skin rash.
 The best way to reduce the use of these chemicals and reduce soil
pollution is by organic farming. In organic farming in place of chemical
fertilizers, insecticides and weeds, bacterial fertilizer nutrients Contribute
less waste to help prevent soil pollution. Purchase glass and other reusable
containers instead of throwing away plastic or paper regularly.

8. NOISE POLLUTION
 Noise pollution, also known as environmental noise or sound
pollution, is the propagation of noise with harmful impact on
the activity of human or a
 Noise pollution can come from a variety of sources, but the
three most damaging sources are industrial machinery,
vehicles, and construction
 occurrence of aggressive behavior, disturbance of sleep,
constant stress, fatigue, and hypertension can be linked to
excessive noise levels.
 Turn off Appliances at Home and offices ,Use Earplugs,
 Lower the volume, Stay away from Noisy area,Follow the
Limits of Noise level,Control Noise level near sensitive areas.

9. THERMAL POLLUTION
 Thermal pollution is the harmful release of heated liquid into a
body of water or heat released into the air as a waste product of
a business.
 Water as Cooling Agent in Power, Manufacturing and
Industrial plants ,Soil Erosion, Deforestation,Runoff from
Paved Surfaces .
Thermal pollution damages water ecosystems and reduces
animal populations. Plant species, algae, bacteria, and multi-
celled animals all respond differently to significant temperature
changes.
 Cooling towers and artificial lakes, Use of alternative cooling
agents- other than water, Release heated water in less
vulnerable regions,Circular plowing to prevent erosion,Reuse
of heated water,Tree planting along the shorelines.

10. RADIOACTIVE POLLUTION
 The radioactive pollution is defined as the physical pollution of
living organisms and their environment as a result of release
of radioactive substances into the environment during nuclear
explosions and testing of nuclear weapons, nuclear weapon
production.
 Mining for nuclear fuel, nuclear waste, nuclear power plant mishaps
and nuclear weapons are all possible sources of radioactive pollution.
Improperly handled material used in nuclear medicine is also another
possible radioactive pollutant.
 Acute health effects such as skin burns and acute radiation syndrome
(“radiation sickness"). It can also result in long-term
health effects such as cancer and cardiovascular disease.
 Radiation Pollution can be controlled and prevented at various
levels, including the handling and treatment of radiation waste,
control and mitigation of nuclear accidents, as well as the control and
minimization of personal exposure to radiation at an individual level.

11. CONCLUSION
 Much is being done to control, monitor and rectify
damage done by pollutants. The problems are diverse
and some are only being recognised but it is important
to keep a close control over pollutants so that we can
maintain the environment in an acceptable condition
for future generations.
