IMM colloquium October 29: 'Monitoring chemical water quality through integration of non-target and effect-based screening' (Lecture)
- Tuesday 29 October 2019Add to my calendar
- from 16:00
dr. Andrea Brunner (KWR Nieuwegein)
The ever increasing production and use of chemicals augment their occurrence in drinking water and its sources to an extent that monitoring using targeted chemical analyses alone is no longer sufficient. Complementary methods, referred to as suspect and non-target screening, are required that are able to detect a multitude of chemicals simultaneously, including mobile and polar compounds in low concentrations. These methods rely on liquid chromatography coupled to high resolution mass spectrometry in combination with novel data analysis workflows. The range of challenges in their application and strategies to overcome these will be presented in the seminar, such as the identification of “known unknowns” and “unknown unknowns” in different water matrices and the confidence thereof, and the use of cheminformatics and data mining for the prioritization of suspect chemicals. Thereby, the seminar will provide an overview of methods to support the water sector in realistically assessing the human and environmental health risks of (emerging) contaminants.
