Challenging tasks, increasing demands, and new generations of powerful analytical instruments initiated considerable progress in aquatic environmental analysis and led to a considerable improvement of analytical performance during the last few years. The ever growing number of emerging pollutants is tackled by specific and highly sensitive analytical methods with detection limits of a few nanogram per liter and even lower. Wide-scope monitoring techniques and multiclass and multiresidue analysis allow for the simultaneous determination of hundreds of compounds. The high mass resolution capability and mass accuracy of advanced mass spectrometric instruments, i.e., time-of-flight (TOF) MS or Fourier transform (FT)-Orbitrap MS, enable combined target and non-target analysis, including the identification of metabolites and abiotic degradation products. This minireview highlights some of the most recent developments in the trace analysis of important organic water pollutants and focuses on some specific groups of emerging contaminants, i.e., pharmaceuticals, flame retardants, disinfection by-products, surfactants, per- and polyfluorinated compounds, benzotriazoles, and benzothiazoles, as well as on the identification of transformation products and on non-target analysis. References were selected according to their exemplary and innovative character and to their practical relevance.
