Organic-geochemical investigations on the mode of incorporation of a defined nonylphenol isomer and the herbicide MCPA in soil derived organo-clay complexes
… from soils. It was assumed, that these non-extractable residues are incorporated in the organic matter or constituents of soils as both, the applied parent compound or a transformation product. Incorporation of the so called "bound residues" depends on several factors such as system …

Struktur- und Bindungsuntersuchungen nichtextrahierbarer 15 N- und 14 C-Simazinrückstände im Boden
… of the structure and binding modes of non-extractable residues (NER) of the triazine herbicide simazine. The chemical environments of unaltered as well as metabolized simazine compounds can be observed directly in soil or compost matrix by 15N-NMR spectroscopy. As the 15N-isotope has a …

Comparison of the biodegradation of pharmaceuticals and biocides in water and soil systems
… environmentally relevant pharmaceuticals, the non-steroidal anti-inflammatory ibuprofen and the antibiotic ciprofloxacin were analysed as model compounds for their turnover in water and soil systems. Isotope labelled compounds (13C, 14C) were incubated in mineral medium (OECD test 301) and in …

Einfluss von Mikroorganismen und Organo-Ton-Komplexe auf die Bildung von nicht-extrahierbaren Rückständen im Boden unter Verwendung von 14 C-Nonylphenol und 14 C-MCPA als Modellsubstanzen
… and organo-clay complexes on the formation of non-extractable residues (NER) of soil. For the purpose of these investigations two test chemicals, 4(3’,5’-dimethyl-3’-heptyl)-phenol (p353-NP) and 2-methyl-4-chlorophenoxyacetic acid (MCPA), were used. To understand the fate and behavior of the …
