Current research

In general, emerging compounds are present at low concentrations in the sources of drinking water. Therefore, concentration of samples is required to overcome sensitivity problems of (bio)analytical tools. The topic research is focused on the development of hybrid sample preparation techniques for polar emerging compounds as present in sources of drinking water. A sample preparation method based on Solid Phase Extraction (SPE) suitable for both chemical analysis and bioassays of a wide variety of organic compounds will be developed. An array of extraction materials and organic solvents will be applied in parallel to extract a wide variety of compounds. Sorption mechanisms of target compounds with a wide variety of properties will be elucidated including organic neutral compounds, organic zwitterions and organic ions. Recovery tests of target compounds in source surface water will be carried out in column studies. The performance of selected and validated sorbents will be tested with field samples. The extracts obtained from the SPE procedure selected applied on source water will be used both for the chemical analysis (broad target screening) and bioassays (CALUX, ames, micronucleous).The concentration levels of target compounds determined will be correlated with the bioassay responses.
