“…This high amount could be evidence that besides sequestration the formation of covalent bonds played a major role in the formation of nonextractable residues . This conclusion is highly supported by stereochemical changes observed in the same course of experiment indicating a high microbial influence on the formation of the hydrolyzable residues . Incorporation into the humic fractions was detected already after one day of incubation.…”

“…37 This conclusion is highly supported by stereochemical changes observed in the same course of experiment indicating a high microbial influence on the formation of the hydrolyzable residues. 19 Incorporation into the humic fractions was detected already after one day of incubation. In FA and HA, radioactivity was released completely after ester (amide) bond cleavage, whereas in humin fraction (HU) the amount released was significantly lower.…”

“…Recently, we demonstrated that nonextractable residues of a specific nonylphenol isomer were preferentially located in soil-derived organo–clay complexes and, in particular, the corresponding humic acid fraction acted as the major sink for this isomer . Furthermore, complementary studies revealed not only a rapid incorporation of the nonylphenol isomer but also an influence of the incorporation process on the stereochemical properties of the contaminant indicating microbial assistance . Following this course of investigations the present study focused on the incorporation processes of the labeled NP isomer in soil-derived organo–clay complexes.…”

For this purpose corresponding incubation experiments of up to 180 days were performed and organo−clay complexes were separated from other soil constituents.…”

The incorporation process of a defined (13)C- and (14)C-labeled nonylphenol isomer (4-(3,5-dimethylhept-3-yl)phenol) into soil-derived organo-clay complexes was investigated. Isolated organo-clay complexes were separated into humic subfractions. Noninvasive ((13)C-CP/MAS NMR) and invasive methods (sequential chemical degradation, pyrolysis) were applied to obtain detailed information about the mode of incorporation, chemical structure, and change of the incorporation character of nonextractable residues in course of incubation. (13)C-CP/MAS NMR measurements of humic acids revealed an increasing incorporation of phenolic compounds during the experimental time which was referred to residues of the introduced (13)C-labeled NP isomer. Detailed investigations by means of sequential chemical degradation indicated a predominant incorporation of nonextractable NP isomer residues via reversible ester (amide) bonds. In course of time, the amount of releasable compounds decreased, pointing to altering processes which affected the mode of incorporation. BBr3-treatment, RuO4 oxidation, and thermochemolysis released only low portions of nonextractable radioactivity giving evidence of strongly incorporated residues. With the comprehensive application of complementary methods (e.g., humic matter fractionation, (13)C-CP/MAS NMR, sequential chemical degradation) it was possible to provide a comparatively detailed insight into the incorporation behavior of the applied NP isomer.

The main objective of this study was the development of simple multi-parameter methods for the analyses of biocides in various environmental matrices (wastewater, surface water, and sewage sludge) for measurement and monitoring activities. Eight target substances (triclosan, methyltriclosan (transformation product of triclosan), cybutryne (Irgarol), and the azole fungicides propiconazole, tebuconazole, imazalil, thiabendazole, and cyproconazole) were chosen for determination in selected sample sets. For surface water and wastewater samples a solid-phase extraction (SPE) method and for sewage sludge samples an accelerated solvent extraction (ASE) were developed. The extracts were analyzed by gas chromatographic-mass spectrometric methods (GC/MS), and the analytical methods were checked to ensure sufficient sensitivity by comparing the limits of quantification (LOQs) to the predicted no effect concentrations (PNECs) of the selected biocides. For quality control, recovery rates were determined. Finally, developed methods were checked and validated by application on sample material from various matrices. Sampling took place in seven urban wastewater treatment plants and their corresponding receiving waters. The results revealed that the developed extraction methods are effective and simple and allow the determination of a broad range of biocides in various environmental compartments.
