Summary: Selenium is an essential micronutrient that plays an important role in the development and physiological homoeostasis of animals and humans. This review discusses the role of selenium in the environment, plants, and animal bodies and explores different sources of selenium supplementation, focusing on Se-enriched yeast. Other potential sources such as Se-enriched insects and Se-nanoparticles are also examined for their use in animal nutrition. The scientific evidence suggests that sodium selenite and Se-yeast are the main options for inorganic and organic selenium supplementation, but further research is being conducted on alternative sources with high bioavailability and reduced environmental emissions.

Summary: Limited studies have been conducted on the translocation and bioaccumulation of selenium in weak alkaline cultivated Se-enriched soil. This study measured selenium levels in various parts of wheat plants grown in Se-enriched soil in Ci County, China. The results revealed significant bioaccumulation of selenium in the roots, and identified phosphorus, pH, and Fe2O3 as the main factors controlling bioaccumulation. The study also identified the sources of selenium in wheat grains and its potential impact on human health.

Summary: The study found that exogenous Se treatment can increase the selenium content in garlic bulbs, and low concentrations of Se application help improve yield and nutritional quality, while high Se concentrations have negative effects on yield and the content of soluble sugar and allicin in garlic bulbs. AMF inoculation can reduce the inhibitory effect of high Se concentration on garlic, and when combined with 10 mg/L exogenous Se treatment, it promotes Se utilization rate.

Summary: This study found that organic selenium accounted for more than 82% of the total selenium in walnut proteins, with selenocystine and selenomethionine being the major forms. The selenium content in walnut proteins was positively correlated with antioxidant ability, and protein hydrolysates exhibited better antioxidant activities than undigested proteins.

Summary: This article explores the fate of selenium inputs from coal-fired power station operations in a marine dominated estuary, Lake Macquarie NSW, as well as the toxicity of selenium, including sublethal and population effects. The study finds that selenium is rapidly adsorbed to sediments and is remobilised by volatilisation and diffusional processes following bioturbation. It is transferred into food chains via benthic microalgae, deposit feeders, and filter-feeding organisms. The article highlights the historical accumulation of selenium in fish and the reduction of selenium concentrations in sediments and fish after remediation measures were taken. It also discusses selenium cycling and the potential sublethal effects caused by selenium. Understanding the fate of selenium inputs and its remobilisation into food webs is crucial for accurate risk assessments.

Summary: This study found that the three-step sequential extraction method (aqueous solution extraction-pepsin extraction-trypsin extraction) performed the best in extracting selenium from high selenium-enriched Ganoderma lucidum, with a total selenium extraction rate of 65% and a total selenium enzymatic hydrolysis rate of 40%. The selenium speciation in this high selenium-enriched Ganoderma lucidum was determined. This study provides a reliable and efficient method to evaluate the selenium transformation and safety in high selenium-enriched edible fungi.

Summary: This study investigated the tissue-specific bioaccumulation characteristics of 19 antibiotics in maricultured organisms at different growth stages, revealing that the bioaccumulation capacity varies among organisms at different stages. Tetracyclines and fluoroquinolones were found to be the dominant antibiotics, with the total concentrations higher in fish compared to shrimp and sea cucumber.

Summary: Viral infection can lead to an imbalance of trace elements in the brain, increasing neurovirulence and neurotoxicity. Synapse vulnerability has been suggested as a potential mechanism for neurological disorders following viral infection. Trace elements play crucial roles in viral infections, although their specific functions remain largely undefined.

Summary: A highly selective and efficient method using graphene oxide (GO) and a magnetic ionic liquid (MIL) for dispersive micro-solid phase extraction (D-mu-SPE) of inorganic Sb speciation analysis was developed. Sb(III) was complexed with sodium diethyldithiocarbamate (DDTC) and retained on GO, followed by magnetization of the sorbent surface with MIL and separation using a magnetic rod. The aqueous phase containing only Sb(V) was directly analyzed by ICP-MS. The method showed high extraction efficiency, low limits of detection, and good precision for Sb(III) and Sb(V) determination. It was successfully applied in the analysis of inorganic Sb species in tap water, tea infusions, and honey samples. The method also demonstrated good environmental performance according to the Analytical GREEnness calculator (AGREE) with a value of 0.61.

Summary: This study presents a rapid and environmentally friendly synthesis method for thermodynamically stable silica nanoparticles (SiO2-NPs) using microwave irradiation (MW) compared to conductive heating. The synthesis method is 30 times faster, uses 4 times less reagents, and is approximately 18 times cheaper than conventional synthesis. The synthesized SiO2-NPs were characterized and found to be stable, monodisperse, and amorphous. After adding SiO2-NPs to the soil used for cultivating soybeans, the homeostasis of Cu, Ni, and Zn in soy leaves was evaluated, and the nanoparticles were found to have an impact on the elemental distribution.
