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
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
