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.
