Samples were pyrolyzed at 700ªC for 10 sec, and low boiling point compounds were separated in a Chromosorb 102 column. Peaks were identifies with a mass spectrometer coupled to the gas chromatograph. Major components from soil humic acids were related to proteins, namely methane, ethene, ethane, propene, propane, butene, acetonitrile, benzene, pyridine, pyrrol, toluene, and phenol, and to polysaccharides, such as acetaldehyde, acetone, furan, methylfuran, 2-butanone, and furfural. Soil fulvic acids gave pyrograms with major peaks of methane, ethene, acetaldehyde, acetone, furan, acetic acid, 2-butanone, benzene, toluene, and furfural, which are characteristic for soil polysaccharides. Bromomethane, an unusual compound, was found in the humic fractions from podzolic soils.Peer reviewedSoil Science Society of America201320131977info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/71741reponame:DIGITAL.CSIC.
