Decades of research demonstrated that microbes can remediate petroleum-contaminated environments through biodegradation of hydrocarbons. Recent studies have applied signature metabolite analysis to investigate hydrocarbon-contaminated sites, focusing primarily on aquifer systems and metabolites of relatively water-soluble monoaromatic hydrocarbons. However, the number of studies involving non-targeted analysis and identification of individual metabolites in environmental samples is limited.

Although proteins in snake venoms have been extensively studied and characterized, low-mass molecules remain relatively unexplored, mainly due to their low abundance, secondary role in envenomation, and some analytical technique limitations. However, these small molecules can provide new important data related to venom toxins' molecular structure, functions, and evolutionary relationships. This research aimed to characterize molecules below 10 kDa in the venoms of snakes from the Viperidae families (Bothrops, Agkistrodon, and Bitis) and compare two chromatographic approaches: reverse-phase chromatography (RP), a classic technique, and hydrophilic interaction liquid chromatography (HILIC), an alternative technique, both coupled with high-resolution mass spectrometry (HRMS).

Benzophenone derivatives (BPs), as synthetic chemicals widely used in personal care products, have drawn increasing attention due to their potential health risks. However, monitoring BPs in biological samples remains challenging due to their complex matrices and the deficiency in sensitivity and selectivity in current methods. Herein, a method combining hierarchically flower-like hollow covalent organic frameworks (HFH-COFs) with high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was established for the enrichment and detection of BPs in serum samples.

The recent unauthorization of antiviral drugs in food-producing animals according to Commission Delegated Regulation (EU) 2022/1644 have increased the need for food control laboratories to develop analytical methods and perform official controls. In this work, a simple and fast analytical methodology was developed for the simultaneous determination of 21 antiviral drugs in chicken muscle and liver by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Chromatographic separation was achieved by an HILIC BEH amide column; followed by detection with a electrospray ionization source in positive and negative modes.

The extensive application of cement kiln industry results in substantial stack gas emissions, posing a potential risk of discharging organic pollutants. Cement industry is not considered as a primary contributor to persistent organic pollutants like polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), owing to its extremely low emission factor. However, knowledge on the previously unrecognized chemicals that may possess higher emission factors from cement industry is lacking.
