How much carbon dioxide would kill you?
CO2 is toxic in higher concentrations: 1% (10,000 ppm) will make some people feel drowsy.
- If exposed at a level of 2% for several hours, minimal "acidosis" (the acid condition of the blood) may occur (cf. hyperventillation prevention).
- Breathing rate doubles at 3% CO2 and is four times the normal rate at 5% CO2.
- Toxic levels of carbon dioxide: at levels above 5%, concentration CO2 is directly toxic. [At lower levels we may be seeing effects of a reduction in the relative amount of oxygen rather than direct toxicity of CO2.]
- Symptoms of high or prolonged exposure to carbon dioxide include headache, increased heart rate, dizziness, fatigue, rapid breathing, visual and hearing dysfunctions.
- Exposure to higher levels may cause unconsciousness or death within minutes of exposure.
- Concentrations of 7% to 10% cause dizziness, headache, visual and hearing dysfunction, and unconsciousness within a few minutes to an hour.
First, all of the plants would die out. Plants need carbon dioxide to survive. Second, carbon dioxide helps keep our planet warm, and without carbon dioxide the planet would be much colder. Too much carbon dioxide, though, increases the planet's temperature. Third, there would be no soda. The bubbles in the soda that raise are actually carbon dioxide.
Photosynthesis, the process plants use to convert carbon dioxide and sunlight into carbon for the plant's use (releasing free oxygen from the carbon dioxide molecules, essentially eliminating the carbon dioxide). Carbon emissions caps, which would reduce how much carbon dioxide humans put into the atmosphere; by reducing the rate of emission, a new lower equilibrium would be achieved and the total volume of carbon dioxide would reduce (if the emissions were lowered to a cap…
Yes it can. We breathe in response to having carbon dioxide in our bloodstream. When the carbon dioxide levels go up, the brain sends a signal that it needs more oxygen, so we take a breath. If you are being given 100% oxygen, after a while, there will be no more carbon dioxide in the bloodstream, so your brain would not know to send a signal to make you breathe.
The organs and cells in your body give off carbon dioxide into your blood as exhaust. The problem is when you inhale high amounts of carbon dioxide in the air so that your blood is overloaded with carbon dioxide. At this point your body temperature would go down and you would die of hypothermia, if not treated immediatly.
Green plants use carbon dioxide as part of the process of photosynthesis. In addition, while we are presently concerned that too much carbon dioxide is resulting in too much greenhouse effect and global warming, it is equally true that too little carbon dioxide would result in global cooling. A certain amount of carbon dioxide is helpful in maintaining the kind of temperature range that we want.
The medulla oblongata is located in the brain, this detects how much carbon dioxide in the blood stream. Too much carbon dioxide can raise the pH and denature enzymes which will essentially kill you :) So the medulla oblongata sends an impulse through the nerves to the diaphragm (which causes us to breath) which makes us breathe faster to get rid of the carbon dioxide.
What would happen if the carbon dioxide in blood reactants with water to form carbonic acid was not catalyzed?
When solar energy hits Earth, a small part of it is absorbed by the ground. Most of it is reflected. If there was no atmosphere, that energy would just go out into space, and earth would be much colder. What greenhouse gases like carbon dioxide do is reflect that energy back to earth, keeping much more heat stay inside. The problem is that lately too much carbon dioxide has led to too much heat.
