ABSTRACT

ABSTRACT: If the biological decomposition becomes non-reactive to standard treatment, a special programme of combined biological and chemical tests must follow to find out whether or not the decomposition has been interrupted by the influence of toxic compounds or unfavourable mechanic conditions. When an interruption has been proved unlikely it is possible and effective to characterize the stability of the organic material using a combination of the Curie-Point Pyrolysis Gas Chromatography/Mass Spectrometry (Py-GC/MS) with the Pyrolysis Field Ionization Mass Spectrometry (Py-FIMS).
