“…Different pollutants have different ratios of gas to liquid, so they each travel through the column at different speeds [14]. The separated pollutants are then analyzed by mass spectrometry.…”

“…Owing to their ionic or polar nature, surfactants are mostly analyzed by reversed phase (RP)-or mixed mode (RP combined with polar interactions and ion exchange)-LC. GC is restricted to NP and other alkylphenols, NPEC, and to their non-ionic degradation products (Gallart-Ayola et al 2010;Klontza et al 2010;Luo et al 2010;Sánchez-Avila et al 2010). Bruzzoniti et al (2008) used anion exchange chromatography in combination with SPE-enrichment on an SDB-1 cartridge for the quantification of alkylsulfonic acids, arylsulfonic acids, and alkylsulfates in seawater.…”

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.

“…Multiresidual methods can provide information of multiple compounds simultaneously. They allow the simultaneous identification and quantification of a wide range of organic contaminants in a single analysis [6,26,27]. Traditional extraction methodologies comprise Solid Phase Extraction (SPE) or LiquidLiquid Extraction (LLE).…”

In the present work, a sensitive, simple, and fast method with little sample handling has been developed for the determination of 34 semi-volatile organic xenobiotics from rain, sea and ground waters. The method is based on Headspace-Solid Phase Microextraction (HS-SPME) and Gas Chromatography coupled to Mass Spectrometry (GC-MS/MS). Sixteen Polycyclic Aromatic Hydrocarbons (PAHs), eight Phthalate Esters (PEs), six Polychlorinated Biphenyls (PCBs) and two Alkylphenols (APs) were quantitative analyzed in a single run. The best parameters for extraction were determined, including fiber type, sample volume, salinity and extraction time and temperature. In the optimized procedure, 15 ml of water sample was extracted using a 100 μm PDMS fiber in a 20 ml vial and adding 3 g of NaCl (final NaCl concentration of 20%) during 40 min at 80°C (with 10 min of previous equilibration time). A desorption time of 15 min was shown to eliminate carry-over. The method showed good linearity between 0.01 and 10 μgL -1 (r 2 from 0.987-0.999). Good precision (63-123%) and accuracy were achieved (1.1-21%). The Methodological Detection Limits (MDL) ranged from 0.00001-0.01364 µg L -1 . The method was successfully applied to real samples collected at Ensenada (Mexico). The proposed method represents an effectively and valuable tool for application in environmental water monitoring programs.
