POLLUTION
What is
Pollution happens when the environment is contaminated or
dirtied by waste, chemicals, gases and other harmful substances.
There are four main forms of pollution
Pollution
Noise pollution
Water pollution
Air pollution
Land pollution
Air Pollution
Air Pollution
Air pollution is actually harmful substances in the atmosphere which damages the environment. With the development of industries, came along the increase in
air pollution.
Form CausesA cloud of smoke from the exhaust of a vehicle
Increasing traffic
Smoke from a factory chimney
Growing cities
Eruption of a volcano Rapid economic development
Cigarette smoke IndustrializationBurning leaves Apathetic people
Effects of Air Pollution-Health problems
-Damage to the environment-Damage to property
-Thinning of the protective ozone layer of the atmosphere which is leading to
climate changes
Birth defects
cancerRespiratory
problems Heart disease Asthma
Tuberculosis Immune system
damageIntellectual disorders
Some Solutions to Air Pollutionshould / share vehicles or use public transport to go to
workshould / get a regular pollution check for our vehicles
should / walk or use bicycles to go to near placeschimneys of factories should be fitted with proper
filters to prevent smokes from coming out and effect the atmosphere
conserve energy:switch off fans and lights when you are going out
Water Pollution
Water Pollution
Water pollution is the contamination of water bodies
(e.g. lakes, rivers, oceans, groundwater). Water pollution occurs when pollutants are
discharged directly or indirectly into water bodies without adequate treatment to remove harmful
compounds.
Form Cause
Toxic substances dissolve in water or gets deposited on the
bed.
City sewage
Toxic substances enter lakes, rivers, streams, etc.
Industrial waste
Pollutants go down into the ground.
Agricultural run-off
Effects of Water PollutionDevastating to people and animals,
fish, and birds.Unsuitable for drinking,
recreation, agriculture, and industry.
Destroys water life.
Diarrhea Vomiting Typhoid Diphtheria
Hepatitis Kidney Damage Nerve Disorders Skin Lesions
Some Solutions to Water PollutionFactories should not throw their
wastes in water bodiesPeople should not bath or wash
clothes in rivers or lakesPeople should not take their animals
to bath in riversor lakes
Land Pollution
Land Pollution
is the degradation of Earth's land surfaces often caused by human activities and their misuse of land resources. It occurs when waste is not disposed properly. Health
hazard disposal of urban and industrial wastes, exploitation of minerals, and improper use of soil by inadequate agricultural practices are a few factors.
Types of wasteHousehold
wasteIndustrial wasteBiomedical or hospital waste
Causes Population increases
Increased plastics products
Changes in lifestyleLandfills not well
equipped to protect against contamination
Effects of Land PollutionOver a long period of time, landfills start to emit landfill gases. Landfill gas is produced due to the
anaerobic conditions that organic wastes decomposed in.
Most waste buried in landfills give rise to hazardous and toxic liquids known as leachates. These leachates
contaminate water sources, like the ground water below the landfills, leading to water pollution.Besides the points mentioned above, it is also
important to note that these over-crowded dumps, contaminated sites and careless disposal of waste also contributes to air and water pollution, as well as, acid
rain.
Since direct impacts of land pollution are air pollution
and water pollution, the key health problems caused by land pollution are same as those of air pollution and water pollution and the additions are increased human injuries, from
syringes, broken glass and cans washing onto river
banks and beaches.
Some Solutions to Land Pollution
People should plant more treesPeople should not throw rubbish in the streets , instead they should use
litter binsIndustries should not throw their
wastes on land
Noise Pollution
Noise Pollution
Sound is essential to our daily lives, but noise is not. Noise is generally used as an unwanted sound, or sound which produces unpleasant
effects and discomfort on the ears.
Causes-Road traffic
-Factories-Loud speakers and other
loud speaking things-Jet planes
-Cinema halls-Household equipments
-Plumbing, boilers, generators…
EffectsTemporary or
permanent deafnessHeadaches and earaches
The physiological manifestations are stress,
irritability and nervousness, feeling of fatigue and decreases
work efficiency.
Some Solutions to Noise Pollution
People should not use lous speakersFactories should be made out of the
citiesThere should not be more noise
making vehicles on the roads
