Summary: This study investigated the bioaccumulation of monomethylmercury (MeHg) in deep-sea fish from the Southeast Atlantic Ocean, revealing that muscle tissue is the main storage site for MeHg, while liver tissue contains the highest total mercury concentrations. The research also highlights the promotion of mercury biomagnification in a tropical upwelling ecosystem, suggesting that upwelling areas may serve as hot spots for monitoring MeHg in marine biota.

Summary: The organomercurial lyase enzyme MerB is capable of MeHg demethylation without subsequent reduction of Hg(II) by the mercuric reductase enzyme MerA. Demethylation of MeHg without Hg(II) reduction leads to increased cytotoxicity and cell lysis. Microbes carrying only MerB have been recently identified but not characterized. Our findings suggest that mer operons encoding MerB but not MerA put the cell at a disadvantage in the context of MeHg exposure, unless additional mechanisms of reduction or Hg(II) sequestration exist.

Summary: This study aimed to determine the mass fractions of inorganic mercury and methyl mercury in soil certified reference material EnvCRM 03 with a complex matrix composition. The contents of inorganic mercury and methyl mercury were established using species-specific isotope dilution inductively coupled plasma mass spectrometry combined with on-line high-performance liquid chromatography or classical off-line chromatography. Different extraction protocols were verified, and both sequential extraction and one-step extraction showed promising results. The developed analytical methodologies were found to be equally sensitive and suitable for speciation analysis of mercury species in complex matrix samples.

Summary: Iron sulfide nanoparticles (FeSNp) have shown to significantly reduce the bioavailability of both Hg(II) and MeHg in aquatic environments, inhibiting MeHg production and integration into food webs, although there is a potential risk of release when the sorbed contaminants are oxidized, increasing exposure risk to aquatic organisms. These findings provide valuable information for the development of in situ Hg remediation systems.

Summary: Micronutrients are vital nutrients that the body needs in small quantities daily to prevent deficiencies. Selenium (Se) is a natural mineral found in foods and is essential for the functioning of selenoproteins, which are crucial for maintaining human health. Monitoring dietary selenium levels and using certified reference materials (CRMs) are important for quality assurance. This review highlights the need for more certified CRMs for selenium species in food analysis laboratories to meet validation requirements and bridge the gap between available food matrix materials.

Summary: The main goal of this study is to determine the sources of methylmercury (MeHg) for high fish-consumption populations, using the Portuguese population as a showcase. Cooked and raw samples of codfish, hake, octopus, horse mackerel, and sardine were considered. The results showed that the loss of moisture during cooking increases MeHg and total mercury concentrations in fish, and the ratio of MeHg to T-Hg in grilled sardines was determined to be 0.43.

Summary: Understanding the uptake and fate of mercury compounds in biota is crucial for understanding the global mercury cycling and its transfer through food chains. This study analyzed mercury concentrations in Scottish birds of prey and found the presence of mercury selenide nanoparticles in the liver of some golden eagles, which has not been observed in terrestrial birds of prey before. The study suggests that these nanoparticles may be formed as a detoxification mechanism or accumulated through foraging on stranded cetaceans or seabirds.

Summary: The availability of electron donors and acceptors in peatlands is closely related to the net formation of MeHg, with differences in younger peatlands potentially contributing to increased Hg(II) solubility and methylation. Understanding these processes can assist in mitigating aquatic MeHg biomagnification in peatland-dominated landscapes.

Summary: Understanding the content of inorganic and organic mercury in organisms or the environment requires speciation analysis. Traditional chromatographic methods coupled with atomic spectrometry have been commonly used, but non-chromatographic atomic spectroscopy methods have also been developed as efficient alternatives in recent years. These methods offer advantages such as time saving, cost-effectiveness, and high detection power compared to chromatographic techniques.

Summary: This study investigated the relationship between hgc genes and MeHg in the redox-stratified water columns of the Baltic Sea. The findings showed that hgc transcript abundance and the concentration of dissolved Hg-II-sulfide species were strong predictors of Hg-II methylation rate and MeHg concentration. The study also highlighted the versatility of putative Hg-II methylators in the water column of the Baltic Sea through genome reconstruction.

Summary: The elemental composition of different processing stages in the production of sparkling wine (cava) has been analyzed using ICP techniques. The data obtained has been used to characterize the wines and identify key elements in the winemaking process. Cu and K were found to be abundant in musts and their concentrations decrease throughout the production process, while S levels increase at the base wine step due to the addition of sulfites. Na, Ca, Fe, and Mg concentrations increase after the first fermentation due to the addition of clarifying agents. PCA was used to efficiently analyze trends and chemical markers within the samples.

Summary: Food safety and quality are increasingly important in our society, driving the development of novel optical food sensing technologies. However, current optical sensing technologies are often limited in their sensitivity and product variability. In this study, we developed a novel pistachio nut screening methodology using fluorescence spectroscopy and advanced chemometrics to simultaneously detect shells, tree parts, and aflatoxins. By optimizing hardware and software parameters, we achieved a high classification accuracy for healthy pistachio kernels.

Summary: This study used bibliometric visualisation map analysis to explore the publication outputs, trends, and hotspots for endocrine disruptors (EDMs) biosensor development in relation to mycotoxins. The analysis showed that the current literature primarily focuses on developing biosensors for detecting highly toxic and widely distributed mycotoxins in food, but there needs to be more focus on biosensors for detecting mycotoxins known as endocrine disruptors.

Summary: Food spoilage is primarily caused by microbial contamination. Curcumin has shown moderate antimicrobial activity as a food preservative. This study formulates curcumin with zinc acetate to enhance its efficacy, resulting in Cur-Zn with increased antimicrobial activity against multiple food-contaminating bacteria and fungi. With light illumination, the antimicrobial activity of Cur-Zn is further enhanced due to the photodynamic inactivation (PDI) effect.
