The discovery of the significant lethal impacts tire additive transformation product N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine quinone (6PPD-Q) on coho salmon has garnered global attention. However, bioaccumulation and trophic transfer additives their products (TATPs) within food webs remain obscure. This study first characterized levels compositions 15 TATPs in Pearl River Estuary, estimated potential 21 estuarine species, identified priority contaminants. Our observations indicated that were prevalent environment. Eight, six, seven, 10 quantified shrimp, sea cucumber, snail, fish samples, with total mean 45, 56, 64, 67 ng/g (wet weight), respectively. N,N′-Diphenyl-p-phenylenediamine (DPPD) N,N′-bis(2-methylphenyl)-1,4-benzenediamine (DTPD) exhibited high bioaccumulation. Significant biodilution was only for benzothiazole, while DPPD DTPD displayed biomagnification trends based Monte Carlo simulations. mechanisms trophodynamics could be explained by chemical hydrophobicity, molecular mass, metabolic rates. Based a multicriteria scoring technique, DPPD, DTPD, 6PPD-Q as work emphasizes importance biomonitoring, particularly specific hydrophobic additives.

This study attempted to integrate contents emissions OPEs from building materials assess human effects. Thirteen were investigated in 80 pieces six categories materials. ubiquitous ∑13OPE varied significantly (p < 0.05) 72.8 ng/g (seam agent) 109,900 (wallpaper). Emission examined based a microchamber method. Depending sample category, observed initial area-specific rates ∑13OPEs 154 ng/m2/h (carpet) 2760 (wooden floorboard). Moreover, rate model was developed predict release levels individual OPEs, quantify source contributions, associated exposure risks. apportionments exhibited heterogeneities multiple environmental media. The joint OPE contribution wallpaper wooden floorboard dust up 94.8%, while latex paint main contributors air (54.2%) surface (76.1%), respectively. Risk assessment showed that carcinogenic tris(2-chloroethyl) phosphate (3.35 × 10–7) close acceptable level (1 10–6) deserved special attention.

Organophosphate esters (OPEs) are increasingly recognized as pervasive environmental contaminants, primarily from their extensive application in flame retardants and plasticizers. Despite widespread presence, the intricacies of OPE bioaccumulation within aquatic ecosystems remain poorly understood, particularly determinants influencing distribution dynamics across food chains. Here we show that water temperature plays a crucial role modulating dispersion environment Poyang Lake. We quantified concentrations various matrices, uncovering levels ranging 0.198 to 912.622 ng L−1 water, 0.013–493.36 per g dry weight (dw) sediment, 0.026–41.92 wet (ww) plankton, 0.13–2100.72 dw benthic invertebrates, 0.31–3956.49 wild fish, highlighting pronounced gradient. Notably, intestines emerged principal site for absorption, displaying highest among seven tissues examined. Among OPEs, tris(chloroethyl) phosphate was distinguished by its significant potential web, suggesting need heightened scrutiny. The propensity accumulation markedly higher invertebrates than indicating differential vulnerability biota. This study lays foundational basis risk assessment OPEs emerging contaminants underscores imperative prioritize examination effects, inform future safeguarding strategies.

Hydrophobic organic contaminants (HOCs) are conventionally screened by matching electron ionization (EI) mass spectra acquired using gas chromatography–mass spectrometry (GC–MS) to reference spectra. However, extensive in-source fragmentation hampers de novo structure elucidation of novel substances that absent from EI databases. To address this problem, a new method based on GC-atmospheric pressure chemical (APCI) coupled ion mobility-high resolution (IM-HRMS) was developed for simultaneous target, suspect, and nontarget screening HOCs. Of 102 target chemicals, 85.3% produced (quasi-)molecular ions as base peaks, while 71.6% displayed detection limits lower than those GC-EI-low MS. The optimized applied standard sediment sediments the Baltic Sea, an Arctic shelf, Norwegian lake. In total, we quantified 56 chemicals with concentrations ranging 4.86 pg g–1 124 ng dry weight. Further, combination full scan spectrum, retention time, collision cross section (CCS), total 54 suspects were identified at Confidence Level (CL) 2. Among remaining features, 169 prioritized halogen-selective CCS cutoff (100 Å2 + 20% mass), leading annotation (CL ≤ 3). Notably, suite fluorotelomer thiols, disulfides, alkyl sulfones in 1–2) first time. Overall, work demonstrates potential GC-APCI-IM-HRMS next-generation technique resolving complex HOC mixtures environmental samples through exploitation molecular ions.
