Environmental Pollution
- Definition
- Pollution
- Addition of undesirable material into the
environment as a result of human
activities
- Types of pollution
- AIR
- Presence of any solid, liquid or gaseous
substance including noise and
radioactive radiation in the atmosphere
in such concentration that may be
injurious to humans and plants.
- Suspended
particulate
matter
- Dust and soot from industrial
chimneys, power plants, cars,
construction activities, etc
- Dust and soot from industrial
chimneys, power plants, cars,
construction activities, etc
- Gaseous
- Petrol and diesel as fuel from industries
and cars release gaseous pollutants such
as carbon dioxide, oxides of nitrogen and
sulfur dioxide cause respiratory
problems, and disordes among others.

- Prevention and
control of Air Pollution
- 1. Use cleaner fuels like LNG and biogas.
- 2. Installing devices like filters,
scrubbers,inertial collectors, etc
- 3. Environmental friendly industrial processes to minimize
hazardous waste.

- NOISE
- Any unwanted environmental sound that is generally
considered likely to annoy, distract or even
harm other people. Anything above 80 dB is
hazardous
- Indoors
- Radio, television, electric
fans and family conflict.
- Radio, television, electric

- Outdoors
- Loudspeakers,
automobiles, traffic,
machines and
industrial activities.

- Control and prevention of Noise
Pollution
- 1. Better design and
maintenance of vehicles.
- 2. Sound proofing equipment like
generators in industries.
- 3. Loudspeakers should be prohibited
by night
- 4. Use green belt trees for noise
absorption.

- WATER
- The addition of harmful chemicals to natural
water caused by industrial, agricultural and
domestic activities
- Sewages with human and animal waste, pesticides like
DDT, metals like lead, zinc, arsenic, copper and
accidents of oil tankers.
- Control Water Pollution
- 1. Waste water recycling for certain uses
with or without treatment.
- 2. Do not dispose household chemicals or
cleaning agents down the sink or toilet.
- 3. Run the dishwasher or clothes washer only when you
have a full load to reduce electricity and water usage.

- SOIL
- The contamination of soil with harmful
substances that can adversely affect the quality of
the soil and the health of those living on it.
- Plastic bags, sewages, fly ash, medical
waste, organic matter, etc
- Control of soil pollution
- 1. Stop use of plastic bags, instead use
degradable bags.
- 2. Treat sewages before using
them as fertilizers.
- 3. Biomedical waste separately
collected and incinerated.

- The contamination of soil with harmful
substances that can adversely affect the quality of
the soil and the health of those living on it.
- THERMAL
- The rise in the temperature of rivers
or lakes that is injurious to
water-dwelling life
- Waste heat generated from electric power plants
and run-off stemming from hot paved surfaces. Use
of water as a cooling agent in natural gas, nuclear
and coal power plants.
- Control Thermal
Pollution
- 1. Store hot water in cooling ponds and allow
it to cool before releasing it
- 2. Use cooling towers to transfer waste heat to the
atmosphere through evaporation and heat transfer.
- 3. Recycle waste heat for domestic and industrial heating
purposes. (cogeneration)

- RADIATION
- Increase in over the natural background radiation
- Radioactive minerals, Cosmic rays, Radio nuclides,
Nuclear power plants, Radio-active wastes, Nuclear
explosions, Radio-isotopes, etc
- Control Radiation Pollution
- 1. The disposal of radioactive material must be safe and secure. They
must be stored in the safe places and must be changed into harmless
form.
- 2. The nuclear power plants must follow all the safe instructions
- 3. Production of radio isotopes should be minimised.
