Chitosan Oligosaccharide Cross‐Linked Piperazine Pyrophosphate/Melamine Polyphosphate Modified Silicone‐Acrylic Emulsion‐Based Flame‐Retardant Coating

Safety Science and Technology, EarlyView.
Chitosan oligosaccharides, as the modifier, significantly enhances the crosslinking degree of piperazine pyrophosphate and melamine polyphosphate, enabling the composite coating to form the interpenetrating network integrating Si‐P‐C‐N during combustion.

Engineering Phosphorus–Iron Coordination Complexes for Simultaneously Fire‐Retardant and Enhanced Epoxy Resins

Safety Science and Technology, EarlyView.
This flame‐retardant epoxy composite realizes synergistic fire suppression via gas‐phase and condensed‐phase dual mechanisms. In the gas phase, phosphorus‐containing radicals trap active H· and OH· radicals to interrupt flame combustion chain reactions. In the condensed phase, Fe species act as Lewis acid co‐catalysts to promote char formation, and the

Enhanced Flame Retardancy and Mechanical Properties of Thermoplastic Vulcanizate by a Multi‐Piperazine/Melamine Vinylphosphonate System

Safety Science and Technology, EarlyView.
Novel vinyl‐containing intumescent flame retardants NV and MV were applied to TPV. The optimized 6NV/4MV system forms dense char layers to boost fire safety, and maintain mechanical performance without compatibilizers. ABSTRACT To meet the dual demands for flame retardancy and mechanical performance of thermoplastic vulcanizate (TPV), two ...

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.
