The Oxygen Problem - Bonphul Air Products

Ideally, air should have 21% Oxygen, 78% Nitrogen, and 1% other gases; this is the air you breathe in the mountains or open fields. Unfortunately, the oxygen level in our cities is low, and it is even lower in our homes and offices. Hence, we are all living with oxygen deficiency.

1. The Oxygen Problem.

You breathe in oxygen and exhale carbon dioxide. Oxygen is used in our cells
as the fuel that transforms the food we eat into energy.

3. Your diaphragm expanded allowing you to inhale. The air you inhaled was filtered
through your nostrils before reaching your lungs. The alveoli in your lungs exchanged
oxygen from the inhaled air and helped release carbon dioxide from your blood to
oxygenate it. The diaphragm then contracted to help you flush out the used air. This
oxygenated blood was supplied to various body parts by circulation of blood.

5. What is Air Quality Index?
Air Quality Index(AQI) is a number used by government agencies to communicate
to the public how polluted the air currently is or how polluted it is forecast to
become. As the AQI increases, an increasingly large percentage of the population is
likely to experience increasingly severe adverse health effects.
What is Air Pollution?
Air pollutionconsists of gaseous, liquid, or solid substances that, when present in
sufficient concentration, for a sufficient time, and under certain conditions, tend to
interfere with human comfort, health or welfare, and cause environmental damage.

7. How we try solve this problem?
We control the air in our immediate surrounding (indoors) by keeping all doors and
windows closed –essentially creating an air bubble in our indoor space. The quality
of this indoor air is measured by Indoor Air Quality Index.
The indoor air at most of our homes is then treated with the help Air purifiers to
minimize the PM particle concentration.
oIndoor air up to 5 times worse than outdoor (EPA)
oAir quality is the single biggest environmental hazardin the world( WHO)
o72% of the toxic chemicals are indoor (UL)
oMore than 9 million in India die due to pollution and more than 1.2 million die
due to bad indoor air.
oPollution kills more people than wars and terrorism today.
Just imagine what this air does to your health and body!

9. The problem we create.
The flame of the candle under the glass jar extinguishes after the oxygen in it
is depleted. In our enclosed spaces (homes/offices/schools/cars) we are like
this candle.
Wherever there are people or animals in an enclosed space there is a
progressive decrease in Oxygen levels.

Ideally, air should have 21% Oxygen, 78% Nitrogen, and 1% other gases; this is the
air you breathe in the mountains. Unfortunately, the oxygen level in our cities is low,
and it is even lower in our homes and offices.

14. Oxygen (O) has an atomic number of eight. This odorless, colorless gas has eight
protons in the nucleus, and is pale blue in its liquid and solid states.
What is the source of Oxygen?
71% of the earth's surface is taken up by water.
The seas are an important source of
oxygen.National Geographicclaims that

The other half, they claim, is produced on land
by trees, shrubs, grasses, and other plants.

atmosphere.

17. How much oxygen do we consume?
An adult male’s average oxygen consumption:
Per Hour –96 Litres
Per Day –2310 Litres
Per Year –843,150 Litres [0.84 Million Litres]
In an average lifetime [75 Years] –63,236,250 Litres [63 .2 Million Litres]
Average human beings roughly take 23000 breaths per day. Average adult at rest inhales
and exhales approximately 7 to 8 litresof air per minute. That totals to around 11,000
litres of air in a day. The air inhaled is about 21-percent oxygen, which means
approximately 2310 litres of oxygen per day.
If you are sitting in an oxygen zone of 17% concentration, it means your intake of oxygen is
1870 litres, a deficit of 440 litres of oxygen.
Air exhaled is about 15-percent oxygen [provided you get air at 21 % oxygen], so about 5-
percent of the volume of air is consumed in each breath and converted to carbon dioxide.
Therefore, a human being uses about net 550 litres of pure oxygen per day.

18. How much oxygen do we consume?
A 12-meter tree weighing about 2 tonnes and significant girth generate approximately
260 pounds /118 KG/ 82,517 litres of oxygen per year as per various reports. So every
Adult needs at-least 10 fully grown trees just to supplement their breathing
requirements.
The tree per person ratio in Delhi NCR : 0.3trees per person!

19. Why aren’t we bothered?
Oxygen deficiency in outdoor air is primarily associated with rapid urbanization,
depleting green cover, and increased usage of combustible engines. This
phenomenon is observed mostly in developing countries on a high growth trajectory.
Oxygen deficiency in indoor air is an indirect result of keeping indoors airtight
because of air conditioning [AC only re-circulates the indoor air, and have no
provision of taking outdoor air], and increased number of people in a closed
environment. So, the deficiency of oxygen is a localized problem for developing
countries /geographies.
Other global issues drive most of the time the media attention. We do hope to see
more media attention towards oxygen deficiency in times to come.
The reason there is a green tribunal is only to protect the green cover and prevent
the erosion of oxygen wealth.
