“…o,p'-DDT is reported to show enantioselective oestrogenicity since (-)-o,p'-DDT is a weak oestrogen mimic while (+)-o,p'-DDT is inactive [5,12,13]. These chiral compounds are separated by using columns with a ß-cyclodextrin stationary phase specifically developed for this purpose [7,9,[13][14][15][16][17][18]. However, coelution of compounds in complex environmental mixtures can make forensic determinations difficult.…”

“…To overcome the problem of coelution, chiral analysis of POPs is generally performed by heart-cut multidimensional gas chromatography (MDGC) [7,11,[15][16][17][19][20][21][22] and comprehensive two-dimensional gas chromatography (GC x GC) [11,15,17,19]. An excellent review of multidimensional chromatography in pesticides analysis can be found in Tuzimski [23].…”

In rural parts of South Africa the organochlorine insecticide DDT (1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane) is still used for malaria vector control where traditional dwellings are sprayed on the inside with small quantities of technical DDT. Since o,p'-DDT may show enantioselective oestrogenicity and biodegradability, it is important to analyse enantiomers of o,p'-DDT and its chiral degradation product, o,p'-DDD, for both health and environmentalforensic considerations. Generally, chiral analysis is performed using heartcut multidimensional gas chromatography (MDGC) and, more recently, comprehensive two-dimensional gas chromatography (GC x GC). We developed an off-line gas chromatographic fraction collection (heart-cut) procedure for the selective capturing of the appropriate isomers from a first

“…Timeof-flight (TOF) and Orbitrap analyzers have been used for LC-HRMS screening of compounds such as drugs of abuse, pharmaceuticals, pesticides and their TPs (Leendert et al, 2015;Ibáñez et al, 2008) in waters. Multiclass screening methods based on GC-TOF MS have been also applied for the investigation of persistent organic pollutants (POPs) (Plaza-Bolaños et al, 2013;van Leeuwen and de Boer, 2008) and other nonpolar organic contaminants including several pesticides, PAHs, and octyl/nonyl phenols (Portolés et al, 2011;Portolés et al, 2014). The combined use of LC and GC, both coupled to HRMS, is nowadays the most powerful strategy to investigate large number of contaminants with different polarities and volatilities.…”

The solid-waste treatment plant of RECIPLASA is located in the municipality of Onda (Castellón province), which is an important agricultural area of Spain, with predominance of citrus crops. In this plant, all urban solid wastes from the town of Castellón (around 200.000 inhabitants) and other smaller towns as Almassora, Benicàssim, Betxí, Borriana, L'Alcora, Onda and Vila-Real are treated. In order to evaluate the potential impact of this plant on the surrounding water, both surface and groundwater, a comprehensive monitoring of organic pollutants has been carried out along 2011, 2012 and 2013. To this aim, an advanced analytical strategy was applied for wide-scope screening, consisting on the complementary use of liquid chromatography (LC) and gas chromatography (GC) coupled to mass spectrometry (MS) with quadrupole (Q)-time of flight analyser (TOF). A generic solid-phase extraction with Oasis HLB cartridges was applied prior to the chromatographic analysis. The screening included more than 1,500 organic pollutants as target compounds, such as pesticides, pharmaceuticals, veterinary drugs, drugs of abuse, UV-filters, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), among others. Pesticides, mainly herbicides, were the compounds more frequently detected. Other compounds as antioxidants, cosmetics, drugs of abuse, PAHs, pharmaceuticals and UV filters, were also identified in the screening though at much lower frequency.Once the screening was made, quantitative analysis focused on the compounds more frequently detected was subsequently applied using LC coupled to tandem MS with triple quadrupole analyzer. In this way, up to 24 pesticides and transformation products (TPs), 7 pharmaceuticals, one drug of abuse and its metabolite could be quantified at sub-ppb concentrations. Along the three years of study, ten compounds were found at 3 concentrations higher than 0.1 g/L. Most of them were pesticides and TPs, a fact that illustrates that the main source of pollution seems to be the agricultural activities in this area.

Analytical strategy based on the use of liquid chromatography and gas chromatography with triple-quadrupole and time-of-flight MS analyzers for investigating organic contaminants in wastewater

The presence of a wide variety of organic pollutants with different physico-chemical characteristics has been investigated in wastewater samples from a municipal solid waste treatment plant placed at Castellón, Spain. An advanced analytical strategy has been applied, consisting on the combined used of two powerful and complementary techniques, GC and LC, both hyphenated with tandem mass spectrometry with triple quadrupole analyzers. The GC-MS/MS method was based on sample extraction using The most commonly detected pollutants were herbicides (simazine, terbuthylazine, terbutryn, terbumeton, terbacil and diuron), together with fungicides (thiabendazole and carbendazim) and 4-t-octylphenol. In the light of data obtained, it has been proven that reverse osmosis process used for water treatment was efficient and notably reduced the levels of organic contaminants found in raw leachate samples. 3In order to investigate the presence of other non-target contaminants, water samples were also analyzed by using GC-TOF MS and LC-QTOF MS. Several organic pollutants that did not form a part of the previous list of target contaminants were identified in the samples, thanks to the good sensitivity of TOF MS in full spectrum acquisition mode and the valuable accurate mass information provided by these instruments. The insecticide diazinon, the fungicide diphenylamide, the UV filter benzophenone, N-butyl benzenesulfonamide (N-BBSA), the insect repellent diethyltoluamide, caffeine or pharmaceuticals like erythromycin, benzenesulfonanilide, ibruprofen, atenolol or paracetamol, were some of the compounds identified in the water samples analyzed.
