title: [The concentration of methane and trace organic admixtures in the air expired by submariners during a dive simulation in a hyperbaric chamber].
abstract: The article describes the procedure of determining methane and some organic trace elements in expired air during simulated "dive" in a hyperbaric chamber. Partial pressures of methane breathed out by divers in 29 experiments are reported. Concentrations of 8 trace organic components have been measured in the expired air of two divers. The results obtained show that expired methane increases by 3-10 times during simulated descent down to 80-115 m.
