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.
