Starting in the mid-1990s liquid-chromatography electrospray ionization mass spectrometry has revolutionized organic trace analysis in several ways: (i) it made polar and non-volatile contaminants and their transformation products detectable, (ii) it provided both high sensitivity and high selectivity by so-called tandem mass spectrometry, (iii) with high mass resolving power it delivers molecular formulas for unknown compounds, and (iv) today virtually any mixtures of seemingly unlimited complexity can be resolved by ultrahigh resolution mass spectrometry.

Some example of our work will be presented that illustrate how the application of modern mass spectrometry contributes to our understanding of the behaviour of chemicals in the environment. These examples may include a multimethod for the determination of pesticide metabolites from water, the uptake of contaminants into and transformation in biota and the application of LC-MS for human biomonitoring.
