“…Some studies have reported non-targeted screening for EOCs by gas chromatography (Slobodnik et al 2012) and liquid chromatography (Hernández et al 2014). Comprehensive two-dimensional gas chromatography -time-of-flight mass spectrometry (GC×GC-TOFMS) has also been recently utilized to enable automated comparison of environmental samples and blanks to identify EOCs as outliers of the normal sample matrix (Prebihalo et al 2015). Non-targeted analysis has previously been carried out in Finland by Nurmi et al 2012and Jernberg et al (2013a, 2013b.…”

Emerging organic contaminants in wastewater are usually analyzed by targeted approaches, and especially estrogens have been the focus of environmental research due to their high hormonal activity. The selection of specific target compounds means, however, that most of the sample components, including transformation products and potential new contaminants, are neglected. In this study, the fate of steroidal compounds in wastewater treatment processes was evaluated by a nontargeted approach based on comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry. The potential of the nontargeted approach to generate comprehensive information about sample constituents was demonstrated with use of statistical tools. Transformation pathways of the tentatively identified compounds with steroidal four-ring structure were proposed. The purification efficiency of the wastewater treatment plants was studied, and the distribution of the compounds of interest in the suspended solids, effluent water, and sludge was measured. The results showed that, owing to strong adsorption of hydrophobic compounds onto the solid matter, the steroids were mostly bound to the suspended solids of the effluent water and the sewage sludge at the end of the treatment process. The most abundant steroid class was androstanes in the aqueous phase and cholestanes in the solid phase. 17β-estradiol was the most abundant estrogen in the aqueous phase, but it was only detected in the influent samples indicating efficient removal during the treatment process. In the sludge samples, however, high concentrations of an oxidation product of 17β-estradiol, estrone, were measured.

“…They also reported that compared to commonly used cyanopropylphenyl polysiloxane, the SLB‐IL111 column showed a shorter analysis time for the baseline separation and quantification of nitrosamines. Prebihalo et al used two‐dimensional gas‐chromatography coupled with time‐of‐flight mass spectrometry (GC × GC‐TOFMS) for analyzing ECs in WW. They reported that the analytical technique permitted the identification of halogenated benzotriazoles in WW and the use of the GC × GC‐TOFMS technique proved to be a valuable tool in resolving complex matrices, as it allows the analyst to separate target compounds.…”

The scarcity of industrial and domestic use water has become an important issue as industrial operations and localized pollution have burgeoned over the last decade. Wastewater (WW) treatment for recycling and reuse is gaining importance as an alternate source of water supply to circumvent water shortages. Wastewater treatment requires thorough planning, design, construction, and management of treatment facilities in order to discharge the treated water to the aquatic environment or for recycling and reuse. One detrimental effect of growing populations and urbanization has been the release of many persistent emerging contaminants (ECs) to the environment, mainly detected in WW. The entry of these ECs to the aquatic environment through wastewater treatment plants (WWTPs) may cause different ecological risks such as reproductive toxicity, endocrine disruption, and microbial resistance. The quantification of ECs (in ng or pg level) in complex matrices, such as WW samples recognized through non-target screening approaches, has played a key role in the planning and design of water treatment facilities. The purpose of this review is to provide information about advancements in wastewater treatment technologies such as constructed wetland (CW) and advanced oxidation processes (AOPs) and the fate of emerging contaminants during these treatments. Further, this review also reports the ecological effects of these contaminants and their by-products formed during various advanced WW treatment processes. The review also discusses advancements in different analytical techniques for the analysis of ECs in WW.
