Abstract
Naturally occurring organic matter from terrestrial and aquatic environments was isolated and degraded by treatment with permanganate and hydrogen peroxide. The formed aromatic degradation products were then analysed by GC-MS (gas chromatography - mass spectrometry) and GC-AED (gas chromatography - atomic emission detection). The results showed that chlorinated 4-ethoxybenzoic acids were the most prevalent halogenated aromatic degradation products. Brominated and iodinated products were found after degradation of a marine fulvic acid and organic matter leached from a calcareous fen soil. No halogenated products were found after oxidative degradation of base-leached organic matter from fresh spruce wood.
