The document discusses different types of environmental pollution including air, water, soil, noise, and their causes. It provides details on major air pollutants like sulfur and nitrogen oxides, carbon monoxides, and chlorofluorocarbons which can cause respiratory issues. Water pollution is discussed in context of rivers and lakes, noting it can spread diseases and harm aquatic animals. Soil pollution has industrial and agricultural sources, and can lower soil fertility. Noise pollution over 80-90dB can damage hearing. Suggestions to reduce pollution include use of renewable energy, waste treatment, reducing pesticides and recycling.

2. The contamination of
environment with harmful
(toxics and poisonous)
substances due to
certain natural
phenomena and human
activities is called
environmental pollution or

5. 1. Oxides of sulphur: Sulphur oxides are highly
suffocating gases. These gases respiratory
problem and damage lungs, produce acid rain
and causes corrosion.
2. Oxides of nitrogen: Oxides of nitrogen causes
lung congention,and produce smog.
3. Carbon monoxides: Carbon monoxides is a
highly poisonous gas. If inhaled, it causes
nausea, headache and giddiness. Inhalation of
carbon monoxides leads to death in a few
minutes time.
4. Chlorofluorocarbons: Chlorofluorocarbons are
used in sprays, shaving forms and as
refrigerant in old model refrigerator in old

6. For big,cities,rivers or
lakes are the sources of
water. In the last few
decades, the quality of
water in many rivers and
lakes has deteriorated
water becomes unfits for

7. 1) Polluted water can cause many
diseases like cholera, dysentery,
typhoid, gastroentritis, hepatitis
(jaundice), and skin diseases in
human beings.
2) Contamination of rivers, lakes etc.
with heavy metals likes lead,
mercury, copper, nickel etc.,can
harm both aquatic animals and

8. Soil pollution is located to
smaller areas as compared
to the air and water
pollution.
Two main causes of soil
pollution are,
Industrial pollution
Agricultural activities.

9. Polluted water affect the soil. The
chemical pollutant get absorbed by the
soil, generally decreasing its fertility.
Even the prolonged use of some
fertilizers reduces the fertility of the
soil by rendering it acidic or basic.
Pesticides absorbed by the soil get
transferred to the plants and then to
animals which eat these plant. Acid rain
renders the soil acidic and unfit for
cultivation. Harmful chemicals from open

10. Noise is not only unpleasant to
the cars. It can also cause
stress, anxiety, sleep
disturbance and permanent
damage to the hearing. It is the
loudness of sound that is
relevant in the context of noise
pollution, or the harmful effect

11. The loudness of a sound is measured
in decides (symbol: dB). Very loud
(140-150 dB), that produced when a
jet plane takes off, can burst the
eardrum. A noise level of 120-140 dB
(not uncommon in a rock concert)can
hurt the ears. Even a noise level of
80-90dB (as in factories and busy
streets) can damage the hearing if

12. Use of energy sources other than fossil
fuels .
Treatment of garbage and sewages.
Reduces the waste of Pesticides and
Recycling and recovery of waste
materials.
Vehicular horns should be used only
when necessary & Machines should be
maintained in a good condition to
reduces industrial noise. People working
