Halogenated structures in natural organic matter

Abstract [en]

Chloroorganics have long been assumed to be almost exclusively of anthropogenic origin, and this assumption has played an important role in the public debate regarding the use of chloriue and emissions of chlorine-containing organic compounds. However, studies undertaken during the past decade have demonstrated that, in general, the total amounts of organically bound chloriue in soil and water by far exceed the possible anthropogenic input.

The results presented in this thesis establish a link between the widespread occurrence of chloroorganics in the environment and the existence of chlorinated aromatic structures in natural organic matter. High molecular weight organic matter was subjected to different degradation methods, and the products of such treatment were then analysed by gas chromatography with atomic emission detection and mass spectrometry. Chlorinated aromatic structures were identified in organic matter derived from seawater, freshwater, groundwater, sediment, soil, and decaying plant material. Several of the identified structures were found to be identical to chlorinated, aromatic structures present in effluents from pulp bleacheries. Brominated and iodinated aromatic structures were detected in all analysed samples from marine environments.

Some of the identified chlorinated structures can be used to distinguish between naturally chlorinated organic matter and organic matter that has been chlorinated in industrial processes, such as bleaching of pulp.
