Abstract: More than 80,000 chemicals are used in commercial products today and many of them eventually find their way into our environment. While modern analytical tools, such as liquid-chromatography mass spectrometry, are able to detect an increasing number of chemicals in environmental samples, little is known about the fate of these compounds in the natural and built environment. In addition, limited information is available about potential toxic effects of most chemicals.
New approaches are needed that link exposures and effects and that ultimately allow for a prioritization of chemicals that are of highest concern. The presentation will discuss how mass spectrometry-based approaches can be used for i) the detection of previously unknown chemicals, ii) the identification of the transformation products that are formed in the natural and built environment and iii) the determination of toxic effects on a molecular level.
