英文摘要	Two new methods for analysis of sedimentary sulfur employing sensitive flame photometric detection have been developed and applied to a study of marine, estuarine and freshwater sediments. Volatile organosulfur compounds generated from freeze-dried sediments upon heating in a H2 atmosphere reflect the distribution and extent of degradation of detrital organic matter. Regions of biogeochemical sulfur transformations, as characterized by the presence of SO2 progenitors, sulfite and thiosulfate, are also depicted. Scrubbing of sediment slurries treated with the reducing agent, acidic Cr(II) solution, releases H2S and CH2SH from their metal-complexed forms. CH3SH is a common constituent of marine and estuarine sediments at sub-ppm concentrations.
