Carbon dioxide on our planet is one of the main components of the environment. In large numbers carbon dioxide contains, for example, in air and mineral underground waters. Without this gas the photosynthesis of plants is impossible, and at living organisms it is the most important component of a metabolism.
In the conditions of the atmospheric pressure of CO2 most often is in gaseous aggregate state. However under special conditions, and in particular at the lowered temperatures (from -78 °C), carbon dioxide is capable to turn into dry ice.
Whether the smell has CO2
One of features of carbon dioxide is that it weighs more air. Also CO2 is very well dissolved in water. This gas belongs to typical acid oxides and can interact with alkalis or water.
In addition, CO2 is not combustible gas and does not even sustain combustion. Unlike the closest relative of carbon monoxide (SO), carbon dioxide is not poisonous and does not represent too big danger to the person in respect of poisonings.
Smell carbon dioxide, as well as charcoal, has no absolutely. And it concerns both its gaseous form, and firm.
Carbon dioxide of people cannot find presence in the room, thus. The only thing, in large numbers of CO2 sometimes begins to irritate mucous a nose.
Whether can cause poisonings
So artfully on a human body as carbon, carbon dioxide does not work. However it is necessary to treat it nevertheless more carefully.
As CO2 more air weighs, indoors it always falls down. And if there will be too much it, it will force out from a floor oxygen because of what at the people who are in the room the hypoxia or an anoksemiya can begin.
Force of impact on a human body of carbon dioxide is low. But at its long inhalation at the victim, in addition, also symptoms of intoxication can develop. In this case everything depends on that how many carbon dioxide will get to an organism.
The scuba divers or people swimming under water with too long tube for breath often face CO2 poisoning problem, for example. Miners, electric welders, workers of the productions specializing in production of sugar, beer, dry ice also get into risk group.
In excess quantities in a human body carbon dioxide begins to connect hemoglobin. As a result at the victim as a special case of a hypoxia, the giperkapniya which is followed by such symptoms as nausea, bradycardia or even paralysis of a respiratory system can develop. Doctors in such cases usually prescribe the victim the medicine "Atsizol" capable, in addition, to expel CO2 from an organism.
