Scientific paper

Laboratory experiments which simulate the breakdown of organic compounds under Martian surface conditions are reported. It is found that organic compounds are destroyed on Mars at rates far exceeding the rate at which they are deposited by meteorites. Thus, the fact that no organic compounds were found on Mars by the Viking Lander Gas Chromatograph Mass Spectrometer experiment can be explained without invoking the presence of strong oxidants in the surface soils. The organic destruction rate may be considered as an upper bound for the globally average biomass production rate of extant organisms at the surface of Mars.
