Carbon Dioxide (CO2)

Health Effects
High concentrations of carbon dioxide can lead to can affect respiratory function and cause excitation followed by depression of the central nervous system and concentrations > 10% result in difficulty breathing, impaired hearing, nausea, vomiting, a strangling sensation, sweating, stupor within several minutes and loss of consciousness.

Properties and Applications:
Carbon dioxide is used to carbonate beverages, decaffeinate coffee, fire prevention, inert atmospheres, aerosol propellant, refrigeration (dry ice). Carbon dioxide is also a product of combustion and biological respiration & fermentation and is a minor component of the atmosphere (~0.035%). Carbon dioxide, > 1000 ppm is used as a marker for poor indoor air quality.
