Current studies have paid extensive attention to the occurrence of brominated flame retardants (BFRs) in aquatic environments; however, there is a lack exploration BFRs ice media freshwater environments, and are fewer on distribution patterns ecological risks different media. In order fill this gap current research status, study conducted four seasonal samplings Songhua River wetland Northeast China. The risk 14 polybrominated diphenyl ethers (PBDEs) 22 new (NBFRs) water, ice, sediment, soil were analyzed using liquid–liquid extraction sample pretreatment gas chromatography–mass spectrometry instrumentation. A total 18, 5, 8, 19, 18 detected non-ice-covered ice-covered soil, respectively. NBFRs dominated contaminant concentrations each medium. Significant correlations found between subglacial suggesting that sources these two similar an exchange them. enrichment factor (IEF) revealed water–ice mechanism BFRs, indicating acts as temporary sink for 2-(Allyloxy)-1,3,5-tribromobenzene (ATE), 1,2-Dibromo-4-(1,2-dibromoethyl)cyclohexane (α-TBECH), 1,2,5,6-Tetrabromocyclooctane (TBCO), 2-Bromoallyl 2,4,6-tribromophenyl ether (BATE). achieve dynamic equilibrium, profile water sediment requires release into water. quotient (RQ) indicated TBCO poses moderate organisms, its potential impact ecology cannot be ignored.

Status and trends of biosensor technologies for environmental monitoring of brominated flame retardants

Frontiers in Analytical Science, Год журнала: 2025, Номер 5

Опубликована: Март 7, 2025

The persistence of brominated flame retardants (BFRs) in the environment and associated toxicological risks have made development efficient rapid detection methods increasingly urgent. Despite regulatory mitigation action many countries, BFRs such as polybrominated diphenyl ethers (PBDEs) tetrabromobisphenol A (TBBPA) continue to threaten ecosystems due their resistance degradation. persist air, water, soil, sediments, bioaccumulate food chain, leading prolonged exposure for both humans wildlife. Additionally, regions with less stringent regulations, products containing are still being manufactured, posing a challenge customs agencies responsible regulating imports. This scenario underscores urgent need rapid, sensitive, cost-effective monitor commercial environmental matrices. Biosensors present promising solution, offering screening BFR contamination at trace levels. Their ability provide accurate, real-time data makes them invaluable monitoring, product safety, compliance. review explores recent advancements biosensor technology detection, highlighting potential improving human health protection but also underlining specific areas that require further research.

Enhanced Flame Retardancy in PA12 Composites via the Synergy of Aluminum Diethylphosphonate and Melamine Polyphosphate

Journal of Applied Polymer Science, Год журнала: 2025, Номер unknown

Опубликована: Май 3, 2025

ABSTRACT To enhance the flame‐retardant properties of polyamide 12 (PA12) and expand its application range, PA12 composites were developed through melt blending with aluminum diethylphosphonate (AlPi) melamine polyphosphate (MPP). Testing revealed that a 5:1 ratio AlPi to MPP achieved outstanding performance when total content was maintained at 25.0 wt%. The synergistic effect significantly enhances flame retardancy PA12, achieving V‐0 rating in UL‐94 test, limiting oxygen index (LOI) value 30.7%. Additionally, peak heat release rate (PHRR) is reduced by 52.8% compared neat while carbon residue increases 2.82 Scanning electron microscopy (SEM) analysis reveals incorporation improves continuity homogeneity char layer formed during combustion. This enhanced effectively inhibited transfer further degradation material. Furthermore, combination restricted mobility polymer chains, increased viscosity, formation droplets both condensed gas phases contributed forming an effective thermal barrier diluting heat.
