Determination of Trace Organic Contaminant Concentration via Machine Classification of Surface-Enhanced Raman Spectra [PDF]
Accurate detection and analysis of traces of persistent organic pollutants in water is important in many areas, including environmental monitoring and food quality control, due to their long environmental stability and potential bioaccumulation. While conventional analysis of organic pollutants requires expensive equipment, surface enhanced Raman ...

Rethinking Chlorine: Essential Chemical or Replaceable Risk?
ChemSusChem, EarlyView.Chlorine is essential for the production of plastics and pharmaceuticals but poses significant safety and environmental risks. Herein, processes are presented that substitute chlorine or reduce its demand. Where indispensable, trichloride‐ and bichloride‐based ionic liquids could enhance safety and streamline the integration of renewable energy ...

Environmental Toxicology and Chemistry, EarlyView.Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Food Frontiers, EarlyView.The mechanism of selenium‐regulatory unique metabolism in rare yeast Kazachstania unispora KU2 was explored via joint analysis of genomics, transcriptomics, and metabolomics. Arginine biosynthesis, glutathione metabolism, selenocompound metabolism, and TCA cycle were significantly associated with the selenium enrichment process in Kazachstania unispora

A Ray of Hope: Gamma Radiation for Microplastic Remediation
Global Challenges, EarlyView.Gamma irradiation is a promising method for degrading microplastics in sewage sludge. Cobalt‐60 doses up to 116 kGy are used, achieving over two‐thirds degradation at the highest level. With further optimization, gamma irradiation could improve wastewater treatment sustainability by minimizing microplastic presence in biosolids and protecting ...

The relationship between cellular protein content and selenium accumulation in freshwater microalgae
Integrated Environmental Assessment and Management, EarlyView.Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...
