Abstract: In modern environmental chemistry applications, there are high demands for providing quickly (bio-)analytical results for multiple chemicals or chemical classes for large numbers of samples. Nowadays, an increased interest is raised for accurate determination in biological and environmental media of contaminants and biomarkers of exposure to estimate exposures and associated health risks. My talk will touch upon the advances in biomonitoring applications with convergence and ultraperformance liquid chromatography and how these advances have changed expectations in the analytical chemistry front, while maximizing the valuable analytical output that feeds into the associated scientific disciplines (e.g., epidemiology). Case studies of phthalate metabolites, bisphenols (BPs) and benzophenone UV filters (BP-UV filters), organophosphate flame retardants (OPFRs), novel brominated flame retardants (NBFRs), legacy and novel per- and poly-fluoroalkyl substances (PFAS), and steroid and thyroid hormones will be disseminated to the audience. Moreover, the importance of applying single rapid sample extraction protocols is presented through a case study that involves PFAS, steroids and thyroid hormones. The benefits of solid phase extraction (SPE) and expected developments are demonstrated. The use of mass spectrometry-based methods will be particularly emphasized due to their well-known superiority over sensitivity, selectivity and precision, even in difficult matrices, such as blood plasma and serum.
