What is Pollution? Defination:When harmful Substances

Contaminating the Environment is Called Pollution OR

Pollution is anything which harms the environment in any way

Pollution refers to the very bad condition of environment.

Different Types Of Pollution.

Air PollutionWater PollutionNoise/Sound PollutionSoil PollutionPesticides pollutionRadio active Pollution

Introduction Of Air Pollution

Any visible or invisible particle or gas found in the air that is not part of the original, normal composition.

Air pollution is the most harmful form of pollution.It is increases day by day.Indicates whether pollutant levels in air may cause

health concerns.Sulphur oxide, Notrogen oxides & Carbon monooxides

are majorPollutant.

What is Smog Smog (Smoke + Fog=Smog) It is Combination of smoke and fog

Forms when heat and sunlight react gases (photochemical smog)

Occurs often with heavy traffic, high temperatures, and calm winds

Air pollution also responsible for Acid rain.

Sulphur dioxide, hydrogen sulphide, Nitrogen oxides togather they form Acid Rain

Acid rain are great threat to british environment.Acid rain are carried away from wind to another

place

Sources of Air PollutionHigh Proportion of undesirable Gases, such as sulphur dioxide and carbon monoxide

which are released by Industries.Gases released by vehiclesMan-made coal, wood and other fuelsThe pollution also accure by naturally By Volcano &

jungle fireGarbage Cigarette smoking Radio active elements Crackers also causes Air pollution.

Effect of Air pollutionSmog related deaths were in London in 1873;

were total 500 peoples was diedCauses respiratory problems and bronchial related

deathsCarbon monoxide from automobiles emissions can

cause headache at low levels andeven death at higher levels

Acid rain affects on aquatic life & other living organisms

Control MeasuresTo reduce emission of nitrogen oxides water should use in

combustion systemAvoid using and use electric stovesDo not Burst CrackersLearn more; stay up to dateUse bio gas on the place of coal for coockingUse LPG in vehiclesRide your bycicleMake sure your parents get pollution checks on their carsBy adopting cleaner tecnologicsPlant more Trees.

Water Pollution

What is Water Pollution? Presence of harmful substances & toxic materials in water

known as ‘Water Pollution’ Water is a precious natural resource. Water Pollution is Caused by organic and inorganic industrial

wastes and effluents discharged into rivers. Water pollution affects plants and organisms living in these

bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the nature biological communities.

About 40% of Deaths worldwide are caused by Water Pollution

Sources Of Water Pollution Sewage & other waste: Sewage are waterborne

waste derived from home(domestic waste) & animals or food processing plants.

It includes human excreta, paper,cloth, soap, detergents etc.

Industrial effluents: A wide variety of both inorganic & organic pollutants are present in effluents from dying textiles, parer & pulp mills, steel idustries, mining corporation etc.

The pollutants includes oils, greases, plastics, metalic wastes, heavy metals, phenols, toxins, acid, dyes DDT etc.

About 180 mollion liters of toxic effluents are discharged into the Periyar river every day by the industrial units in greater Cochin area.

Agricultural waste: These includes chiefly chemicals used as fertilizers

& pesticides used in disease control. They reaches to water bodies along with irrigation,

rainfall, drainage. Sea accidents: Accidents which happen in seas due to this marine

water life also disturbed.

Effects Of Water Pollution.

About 40% of Deaths worldwide are caused by Water Pollution

People are getting diseases like Cholera, Typhoid, Diarrhoea etc.

Aquatic life gets disturbed & hence it affects on human health.

Water pollution also affects the marine food chain.

Fresh water is not available.

Control Measures• Rivers should not be used for washing clothes or

bathing animals in.• Harvesting of Rainwater to meet water

requirements.• Dams & embankments must be created.• The rivers must not be contaminated.• In sacred river like Ganga the dead bodies shouldn’t

thrown.

Noise Pollution

What Is Noise/Sound Pollution

• Noise pollution is defined as unwanted sound which originates from human activities & which is harmful to us & other living organisms.

• What is the difference between sound and noise• In simple terms, noise is unwanted sound. Noise pollution is very harmful for ears.• Sound is a form of energy which is emitted by a

vibrating body and on reaching the ear causes the sensation of hearing through nerves.

• Noise pollution is very harmful for ears.

• The noise originates from human activities, especially the urbanization and the development of transport and industry.

• The sound is pleasant or not depends upon its loudness, duration, rhythm

• Two basic properties of sound are (i)loudness & (ii)frequency.

• Today all cities are becoming noisy places.• The strength of sound measured in term of decible (db).

(deci = 10 & bel after the name of Scientist, A. Graham bell)

• The movement against noise pollution is weak in India. Most of the people do not consider it a pollutant, and take it as a part of routine life.

Sources Of Noise pollution• Transportation:- aircraft ,bus,trains ,cars traffic jams vehicles’

blowing horn.• Special events:-Loudspeakears• Machines in factories produce a lot of sound.• Loudspeaker, used in functions & meetings.• Air craft Noise• Noise from construction and civil engineering works.• Railway engines.• Festival ‘s noise: Fire crackers• Loud noise in houses: T.V ,Tape recorder,

Effects Of Noise pollution.Noise pollution can cause hearing loss & deafnessSleep DisturbanceNoise also causes visual disturbanceLack in concentrationHeavy feelingsIrritated feelingsHeadachesIncrease in heart beats was found amongst industrial

workers in Russia.Noise also affects on patients

Controll MeasuresAir ports must be away from residential area.Hospitals & School Colleges declared as Silent

Zones.The Government should ensure the new machines

that Should be noise proof.Pleasant HomeSound affects our ears so loud noise should be

avoided.
