Abstract Three different molecular weight fractions of fulvic acid from Tjeukemeer, sampled monthly between January and September 1978, were studied by Curie-point pyrolysis-mass spectrometry. The winter samples apparently differed markedly in composition from the summer samples. These differences, which were particularly striking in the pyrograms of the high molecular weight fraction, can be explained in terms of fragment molecules attributable to polysaccharides, proteins and/or phenolic polymers.
