From the link you provided: “Carbon dioxide is produced mainly from six processes… including among others from combustion of fossil fuels
No disagreement there; combustion of any compound containing carbon in an excess of oxygen will lead to the formation of carbon dioxide. Thus, there
is carbon dioxide produced when hydrocarbon fuels (gasoline, diesel fuel, heating oil) or wood (actually any orgabic matter) is burned.
However, in order to get to that toxicity level of 5000 ppmv, it would take a LOT of fuels or wood to be burned. Possibly that amount could be
achieved with engine exhaust, but definitely not with a wood fire. Should the level rise to that point, it would slow the burning process by
But let's take a look at some of the other things you would be breathing:
- Gasoline vapors - including the dreaded Benzene. These are indeed
toxic primarily due to their irritative effects on the mucous membranes and their tendency to combine with ionic compounds in the body, forming
- Carbon monoxide - technically not poisonous, but rather an asphyxiant. It tends to mimic oxygen in the lungs and can attach itself to hemoglobin,
but it doesn't really want to let go like oxygen does. So the victim suffocates to death from an inability of their bloodstream to supply oxygen.
- Sulfur dioxide - a deadly poison that tends to transform into sulfuric acid when in the presence of water, oxygen, and UV radiation. Ironically,
all that is in the air we breath. Can anyone say 'acid rain'?
- Nitrates - the basis for smog. That's what you see hanging over Los Angeles.
- Ozone - normally harmless in small quantities, it is the responsible party for both the fresh smell after a thunderstorm and the sharp biting smell
after a close lightning strike. I understand Sharper Image is selling units that are designed to produce ozone in the home, to make it smell
- Soot - The all-time favorite of chimney sweeps everywhere. It is also a large part of that LA smog, but it at least tends to wash out of the air
easily. It is basically small clumps of unburned solids, mainly carbon.
It would appear to me that if you were sucking on an exhaust pipe, a
little carbon dioxide would be the least of your worries. From Wikipedia
above 5,000 ppm are considered very unhealthy, and those above about 50,000 ppm (equal to 5% by volume) are considered dangerous to animal
5000 ppmv is about 12.5 times
the amount of CO2 in the atmosphere. So if we increase the amount of CO2 by a factor of 12500%, some people will
start getting headaches.
Increase that another 10-fold, a total of 125,000% and it will start becoming life-threatening.
You know, they say water is good for you, but I also know too much can lead to drowning.
The bald fact of the issue is that mankind is destroying the climatic and environmental status quo with our 19th century technologies. I have
no doubt that the earth’s procession and sun cycles have something to do with it as well. However, why do you want to throw gas on the
Because we need more carbon dioxide!
No, seriously, there are plenty of things we can do to make the environment cleaner and easier on us. It's just that society seems to want to forget
about the real dangers and instead focus on a minor condition that isn't that dangerous and is extremely difficult (if not downright impossible) to
Let's talk about not dumping sewage into rivers. Let's talk about not dumping litter in the middle of the Pacific Ocean. Let's talk about
increasing efficiency so cars will burn cleaner and use less gasoline to boot. Let's talk about regulating industrial wastes like HCl or SO2. Let's
talk about minimalizing the amount of packaging being used for products, sometimes more than the product itself. Heck, let's talk about building a
scrubber to clean the air and make it better instead of just not much worse. I'll side with you on these issues, and fight tooth and nail for
What I will not do is lie to myself and others when someone with a lot of money to spend and a lot more to make decides to make it by lying to the
public about a chemical compound that has existed in our atmosphere since life began.
