Abstract Highly polar, persistent organic trace chemicals (PMOCs - persistent and mobile organic chemicals) can break through natural and technical barriers in the water cycle due to their physicochemical properties. Therefore, they are of particular relevance with regard to water quality and even drinking water production. However, so far there has been little research on this group of chemicals. Their concentrations and behavior in the aquatic environment are largely unknown. This has resulted in knowledge gaps for PMOCs within the PROMOTE project. These gaps were found in three areas. First, there was the analytical gap due to the lack of analytical methods for such highly polar compound. Second, there was the monitoring gap, since there are hardly any usable data of PMOCs in the aquatic environment. Finally, there was the regulatory gap because without data in the environment there is no regulation in the authorization of the trace chemicals concerned under REACH.
The aim of this work was to identify PMOCs in drinking water relevant waters, to determine their concentrations and to give first impressions about their behavior during drinking water treatment. For this purpose, persistent and mobile industrial chemicals were evaluated based on their potential environmental emission using a developed substance prioritization system in the first part of thesis (see publication 1 at chapter 5.1). The potential emission to the environment was calculated for 1,110 PMOCs. This emission estimate was used to select analytes for subsequent screening and water monitoring.   In the second part of the project, a target screening for 64 PMOCs in 20 raw water relevant samples was performed using 20 different analytical method combinations within the PROMOTE project. As a result, 43 PMOCs were detected in at least one sample (see publication 2 at chapter 5.2).   Based on this screening work, for which numerous methods were used, a targeted method development with subsequent validation for 17 PMOCs with a log D between -3.06 and 1.23 was subsequently performed for a selected analytical method. Azeotropic enrichment was performed by supercritical fluid chromatography and high-resolution mass spectrometry (see publication 3 at chapter 5.3).   In the fourth part of the study, this analytical method was applied and used for a monitoring. The behavior of 15 PMOCs in five European regions was investigated in conventional drinking water treatment as well as inside a reverse osmosis pilot plant. It was demonstrated that some substances, such as trifluoromethanesulfonic acid, cyanoguanidine, and melamine as well as the sweeteners saccharin and acesulfame could not be removed by conventional water treatment processes. However, reverse osmosis represented an alternative process in water treatment with potential to remove certain PMOCs, such as trifluoromethanesulfonic acid, from contaminated water (see unpublished work at chapter 6).
