Monitoring of iodinated X-ray contrast media in surface water.
TLDR
A point source for ICM contamination between the sampling sites in Ulm upstream and Leipheim downstream seems to be the reasonable explanation for peak ICM concentrations.
Removal of Iodinated X-Ray Contrast Media During Drinking Water Treatment
Environmental Context.In recent years, many micro-organic pollutants, e.g. pharmaceuticals and personal care products (PPCP), have been observed to be persisting through wastewater treatment and
Novel applications of highly sensitive liquid chromatography/mass spectrometry/mass spectrometry for the direct detection of ultra-trace levels of contaminants in water.
TLDR
This work demonstrates that for the analysis of a large number of water contaminants, the sample pre-concentration step could possibly be omitted and is demonstrated to be low to moderate in the case of X-ray contrast media.
Treatment Techniques and Analysis of Stormwater Run-off from Roads in Hamburg, Germany
The treatment of stormwater constitutes an integral part of precipitation water management in Germany. This finds its expression in a variety of treatment concepts which in turn form the basis for
Microbiological characterization of aquatic microbiomes targeting taxonomical marker genes and antibiotic resistance genes of opportunistic bacteria.
TLDR
The abundances of most ARG targets were found to be increased in the bacterial population after conventional wastewater treatment, which underlines the necessity of an advanced microbial characterization of anthropogenically influenced environments.
A survey on trace organic chemicals in a German water protection area and the proposal of relevant indicators for anthropogenic influences
TLDR
A set of nine compounds are proposed to be used as indicators for wastewater, untreated wastewater and runoff water from roads for an efficient surveillance to detect anthropogenic influences in surface, ground and drinking water.
Occurrence and fate of amisulpride, sulpiride, and lamotrigine in municipal wastewater treatment plants with biological treatment and ozonation.
TLDR
It could be shown that all three pharmaceutical compounds are efficiently oxidized by ozonation, leading mainly to N-oxide oxidation products, which indicates N-oxides might be appropriate as indicators for post-ozonation as a major technology for the advanced treatment of secondary effluent.
Formation of oxidation by-products of the iodinated X-ray contrast medium iomeprol during ozonation.
TLDR
Investigation of the formation of oxidation by-products of the iodinated X-ray contrast medium iomeprol during ozonation in water treatment revealed that ICM can be partly oxidized during oz onation processes, whereas the ionic diatrizoic acid showed the lowest reactivity.
Integrated Evaluation Concept to Assess the Efficacy of Advanced Wastewater Treatment Processes for the Elimination of Micropollutants and Pathogens.
TLDR
The results demonstrate the suitability of the evaluation concept to assess processes of advanced wastewater treatment including ozonation and GAC by considering chemical, ecotoxicological, and microbiological parameters.
Identification of ozonation by-products of 4- and 5-methyl-1H-benzotriazole during the treatment of surface water to drinking water.
TLDR
The effectiveness of the methodology for identifying relevant oxidation by-products in the laboratory and subsequently detecting them in an industrial-scale process with the industrial chemicals 4- and 5-methyl-1H-benzotriazole as an example is exemplarily demonstrated.
