Approximately 81% of the nation’s energy needs, Liden reports, are supported by fossil fuels. Increasingly, those fossil fuels are being supplied through unconventional oil and gas development from shale and tight sand formations. As unconventional oil and gas development has grown, so have concerns about water usage, the volumes of wastewater produced, and the need to dispose of the wastewater. To develop environmentally responsible wastewater reuse options, it is important to understand the constituents in the wastewater, current waste management strategies, and challenges within the various treatment modalities. Comprehensive analysis of the wastewater matrix requires multiple analytical techniques, including inductively coupled plasma–optical emission spectroscopy, total organic carbon measurements, and gas chromatography.
Linking LC-HRMS Features to Aquatic Toxicity: A Nontargeted Approach Without Compound Identification
July 7th 2025A recent study conducted by the University of Amsterdam (Amsterdam, Netherlands) and the University of Queensland (Queensland, Australia) developed a novel prioritization strategy that directly links fragmentation and chromatographic data to aquatic toxicity categories, bypassing the need for identification of individual compounds. LCGC International spoke to Viktoriia Turkina of the University of Amsterdam, lead author of the paper that resulted from this study, about their work.
Detection and Risk Assessment of Mycotoxins in Commercial Tortillas Using HPLC-Based Methods
July 4th 2025A joint study between Selçuk University (Konya, Turkey) and Hitit University (Corum, Turkey) determined the natural occurrence and concentrations of the mycotoxins ochratoxin A (OTA) and deoxynivalenol (DON) in commercially available tortillas in Turkey. Contamination levels were quantified using validated analytical methods based on high-performance liquid chromatography (HPLC) coupled with fluorescence or ultraviolet detectors (HPLC-FLD or HPLC–UV).
