Outdoor Pollution
But indoor
air can
be polluted
too . . .
Causes
Fuel burning (wood ,charcoal & animal dung)
Absence of proper ventilation
Smoking (Inhaling secondhand smoking still
take over 4,000 chemicals)
Asbestos, formaldehyde, varnish, paints
Causes
=
1 75-137Amount of
Particulate mass
One burning mosquito coil produces the same
amount of particulate mass (diameter up to 2.5 μm) as
75-137 burning cigarettes
Causes
=
1 51Emission of
Formaldehyde
The emission of formaldehyde from one burning coil
can be as high as that released from 51 burning
cigarettes
Effects
Short term effect – Eye , throat irritation
Long term effect – Respiratory disease , cancer
Expose to high level pollutant such as Carbon
monoxide ,can even result in immediate death
Effects
Outdoor-
5,00,000 deaths/year
Indoor-
22,00,000 deaths/year
(16,00,000 deaths/year Indoor fuel
burning)
Greater impact on developing
countries(INDIA)
Control
Proper ventilation should have to be
provided
Then must have to be plant some indoor
plant …
Control
It can filter benzene,
formaldehyde.
Requires a lot of sunlight.
Aloe Vera
Control
Best indoor plant to remove
formaldehyde from indoor
plant.
It also battles benzene,
carbon monoxide.
Spider Plant
Control
Have bright and colorful
flowers.
Filter carbon monoxide
and benzene.
Gives off oxygen at night.
It is ideal for bed room.
Gerbera
Control
Known as mother-in-law
tongue.
Can filter formaldehyde,
nitrogen dioxide.
At night takes CO2 and
releases O2.
Requires minimal sunlight
& water.
Snake Plant
Control
It can filter formaldehyde.
It grows in any type of light
with an exception to sunlight
(100% artificial lighting).
Very easy to maintain.
Golden pothos
Control
It can filter formaldehyde,
benzene and
trichloroethylene.
Does not need too much
light to grow and thrives in
room temperature.
