Questions of the origin and composition of marine macromolecular organic matter continue to challenge us. A key point that has emerged, especially from NMR studies, is that the formation of randomly cross-linked macromolecules...

Interstellar clouds, tlie birthplace of stars and planetary systems, are rich in simple organic materials and radicals in tlie gas phase and may contain more complex molecules and even macromolecular organic matter on grains. Although these complicated molecules have not been observed in interstellar...

Very recently , we have carried out an intercomperison study of hquid-hquid extraction (LLE) and sorption on polyurethane foam (PUF) and Amberlite XAD-2 for the analysis of aliphatic, aromatic and chlorinated hydrocarbons dissolved in seawater. The application of these methods, sampling in parallel the same body of water, has shown significant differences in the recovery of higher molecular weight components in the complex mixtures of both aliphatic and aromatic hydrocarbons. These are attributed to selective associations of these hydrophobic species with macromolecular organic matter such as fulvic and humic acids and to the effects of the dissolved organic molecules on adsorbent properties.

The anthropogenic contribution to the macromolecular organic matter of riverine systems can be generally attributed to three different processes ... 

In summary, anthropogenic activities cause significant alterations of the macromolecular organic matter (MOM) in riverine and lacustrine systems mainly by emission of pollutants and their subsequent incorporation into geopolymers (bound residues).

Hydrolysis and RUO4 oxidation affected the interactions of the associated substances with the macromolecular organic matter and the alteration of the macromolecular matrix on a very similar mode, despite the different selectivity and reactivity of the degradation agents. The BBr3 treatment affected the incorporation of organic contaminants in a rather different way. 

In contrast the occurrence of only a few substances was spatially restricted. Also only few compounds were determined exclusively after application of one degradation method. For these contaminants a more specific interaction with the macromolecular organic matter of the nonextractable fraction has to be assumed. 

Pyrolysis A procedure that uses high temperatures to break apart macromolecular organic matter, which is difficult to analyze, to produce smaller molecules that can be analyzed.
