How to tackle and reduce Air Pollution ?

[Kashmiri Pandit]

The O-O and N-N bonds do not have the same specific absorption regime for long wave radiation as the C-O bonds (and others like H-O and C-H). They are not greenhouse gases....their effects are minimal given the emission spectra of our star.

No I mean , any biological effect on living beings .
Some one told me that high oxygen percentage will cause Fire in an instant .

The concrete were going to be used for building purposes, thus no matter what, they will be used. But mixing them with this layer, will benefit the environment. Meaning buildings that reduces pollution rather than just buildings.

Yes. i agree with that part.
but i am referring to the contribution of concrete and cement in global warming and "asked" for thinking about this issue "also" ...

I am tackling alcohol and drug issue in and around NCR right now.

That will require a massive increase in oxygen which is very unlikely to happen.

It depends on how long such an increase would take (i.e enough times for humans to adapt).

If overnight its going to double to say 40%, we would face health effects (faster heart rate etc) + greater oxidation which is generally a bad thing for biological systems.

If Nitrogen increases, it would displace the Oxygen (since 100% is the total right?) so that would also be bad for obvious reasons (the start of suffocation).

If we are talking about minute changes in % over long periods of time for both gases, it would be some very long term chronic problems for some sections of the population and it would take hundreds of years or longer for our bodies to adapt.

I am not sure where the % sensitivities lie regarding health problems. Lets just say not too high, not too low is what we prefer since we are used to the current level (though it has not always been this level on Earth, but that was a long time before Humans arrived).

We can't decrease our demand for concrete, it's better to have concrete that help reduce pollution than just having concrete.

I have a question .

Current levels

Nitrogen = 78 %
Oxygen = 20
Carbon Dioxide = 0.04

We all know , That increase in percentage of Carbon Dioxide will adversely affect the Planet .
But what will happen , If levels of Oxygen and Nitrogen Changes .
Example:

Oxygen = 30-40 %
Nitrogen = 60-70 %

"I THINK""" you will not be able to breath. see, there must be some logic of using only 21% oxygen in oxygen tanks. those tanks used for sea divers and mountaineers.

that's not what i am talking about.
See. you cut 100 trees for paper industry. and then you plant 100 trees next day... at the end of day number's remain same =100

but.
if you do not cut those 100 trees . and still plant 100 trees next day.. what will be the outcome ? it can improve things in a more good, feasible and healthy way.

Yes but then you have to find land suitable for growing trees etc. Its not as easy as it sounds given land use and the overall economics of such operations. Trees naturally grow where they do for some very important reasons.

Your intention is definitely good though and governments/societies must definitely spend more time and resources in looking into the problem as a whole.

Ya ! That is what I wanted to know .
DO U think , Level of Gas/Air in atmosphere defines the kind of life exists on Earth or What kind of Evolution may occur ? @RealNapster @Providence @Nilgiri @zebra7

DO U think , Level of Gas/Air in atmosphere defines the kind of life exists on Earth or What kind of Evolution may occur ?

Definitely since these gases are inputs and outputs for the natural biology "equilibrium" that exists in the environment.

It is truly a chicken and the egg situation.

Higher levels of oxygen contrary to our peception will have an adverse effect on humans and other species. Our metabolism rate might increase which can make the other biological processes go for a toss !

someone about 3000 years ago may have said something like that about "mud and soil" ... there is always an option.
first we used rocks.
then we start using wood also.
then we start using binding agent in shape of lime.
then we discovered Portland cement and we start using it.
may be in year 2200 we have 70 % of houses made of plastic.

WTF? NO i work more on a personal level. One bottle at a time.

That's what I thought when I read your previous post.

"I THINK""" you will not be able to breath. see, there must be some logic of using only 21% oxygen in oxygen tanks. those tanks used for sea divers and mountaineers.

You will be able to breathe with no problems....pure oxygen. In fact there are oxygen "bars" in Bangkok that give pure oxygen breathing for some time....and pure oxygen rebreathers are a staple in shallow diving operations.

Prolonged breathing of oxygen is definitely bad, just like prolonged lack of sleep. You put excessive stress on your heart and blood vessels and lung muscles over time. The exact time that is bad varies from person to person and the enrichment of the oxygen.

Yes. i agree with that part.
but i am referring to the contribution of concrete and cement in global warming and "asked" for thinking about this issue "also" .

The catalytic technology will obviously be a net gain for the environment as a whole when you "sum it all up" to find the net contribution. In fact probably many severalfold gain.....similar to a catalytic convertor in a car paying off its environment "damage" (from production) quite quickly and then being a net positive for its duration of life.

Paper is using let say 40-45 % of trees. and they replant them. BUT what about those trees cut by timber mafia's for making furniture, burning wood, etc etc ""?? do they replant trees there ? Still we have that 50-60 % land suitable for trees.

what we lack ?? "Initiative"
