Summary: Complex chemicals have negative effects on the environment and organisms, and conventional chemical-based quantitative analysis may not fully reveal the main contributors to these effects. Effect-directed analysis (EDA) is a powerful method for identifying these contributors. Recent advancements in combining various sampling and sample preparation strategies with EDA have improved the identification of causative components in samples.

Summary: Single-atom site catalysts (SACs) are promising materials for environmental remediation (ER) due to their ability to maximize the utilization of active metal species and regulate the activity and selectivity of catalytic reactions. SACs minimize metal leaching and environmental risks while exhibiting superior activity in various ER processes. However, a comprehensive review on the mechanism and broad application of SACs-based ER is lacking.

Summary: An increasing amount of organic micropollutants (OMPs) are being detected in aquatic environments worldwide, posing a severe threat to freshwater resources, ecosystems, and human health even at trace concentrations. Compound-specific isotope analysis (CSIA) is a key technique for identifying the origin and fate of environmental pollutants in aquifers and characterizing their transformation processes. However, the technique faces challenges in the context of diffuse pollution for other organic compounds.

Summary: The research indicates that environmental flows research in China has rapidly developed over the past two decades (2005-2019), with Chinese authors being among the most productive in the field (60% of the top 20 authors). However, based on citation numbers, few Chinese articles are among the most highly cited (5 out of 800). The need to minimize parochial boundaries in the field of environmental flows research has been identified, and this analysis reveals a rich, untapped literature to promote scientific integration.

Summary: SUPRASs with increased hydrophilicity were synthesized to enhance the extractability of polar compounds. The aggregates formed by self-assembled double-headed amphiphile in hydro-organic media showed highly hydrophilic microenvironments, leading to increased recovery factors for perfluorinated compounds in natural waters. This work demonstrates that hydrophilicity in SUPRASs can be tailored to improve compound extractability in multi-residue analysis.
