The ban/elimination of legacy per- and polyfluoroalkyl substances (PFASs) has led to a dramatic increase in the production use various emerging PFASs over past decade. However, trophodynamics many aquatic food webs remain poorly understood. In this study, samples seawaters marine organisms including 15 fish species, 21 crustacean two cetacean species were collected from northern South China Sea (SCS) investigate trophic biomagnification potential PFASs. Bis(trifluoromethylsulfonyl)imide was...
Per- and polyfluoroalkyl substances (PFASs) have been manufactured widely used for over 60 years. Currently, there are thousands of marketed PFASs, but only dozens them routinely monitored. This work involved target, nontarget, suspect screening PFASs in the liver Indo-Pacific humpback dolphin (Sousa chinensis) finless porpoise (Neophocaena phocaenoides), two resident marine mammals South China Sea, stranded between 2012 2018. Among 21 target perfluorooctane sulfonate 6:2 chlorinated ether...
Atomically dispersed metal-nitrogen sites show great prospect for the oxygen reduction reaction (ORR), whereas unsatisfactory adsorption-desorption behaviors of oxygenated intermediates on metal centers impede improvement ORR performance. We propose a new conceptual strategy introducing sacrificial bonds to remold local coordination Fe-Nx sites, via controlling dynamic transformation Fe-S in Fe-N-C single-atom catalyst. Spectroscopic and theoretical results reveal that selective cleavage...
Liquid crystal monomers (LCMs), commonly used in screens of electronic devices, have recently been identified as a group emerging chemicals concern associated with e-waste. They are potentially persistent, bioaccumulative, and toxic substances, may pose threat to the marine ecosystem. The Pearl River Estuary (PRE) receives organic contaminants discharged from Delta region, where primitive handling e-waste is widespread. However, information on pollution status LCMs PRE absent. Herein, rapid...
Transformation of organophosphate esters (OPEs) in natural ambient air and potential health risks from coexposure to OPEs their transformation products are largely unclear. Therefore, a novel framework combining field-based investigation, silico prediction, target suspect screening was employed understand atmospheric persistence impacts OPEs. Alkyl-OPE ubiquitously occurred urban air. The ratios tris(2-butoxyethyl) phosphate were size-dependent, implying that processes may be affected by...
Stereoisomers of 1,2,5,6,9,10-hexabromocyclododecane (HBCD) and 1,2-dibromo-4-(1,2-dibromoethyl)-cyclohexane (TBECH) were determined in sediments 30 marine species a food web to investigate their trophic transfer. Lipid content was found affect the bioaccumulation ΣHBCD ΣTBECH these species. Elevated biomagnification each diastereomer from prey mammals observed. For HBCD, biota samples showed shift γ- α-HBCD when compared with technical mixtures; magnification potential (−)-α- (+)-α-HBCD...
Restrictions on legacy per- and polyfluoroalkyl substances (PFASs) have led to the widespread use of emerging PFASs. However, their toxicokinetics rarely been reported. Here, tissue-specific uptake depuration kinetics perfluoroethylcyclohexanesulfonate (PFECHS) 6:2 8:2 chlorinated ether sulfonates (Cl-PFESAs) were studied in marine medaka (Oryzias melastigma). The fish exposed these for 28 days (0.2 μg/L), followed by a clearance period 14 days. constant (kd) PFECHS [0.103 ± 0.009 day–1...
Per- and polyfluoroalkyl substances (PFAS) have been applied in numerous industrial consumer products, the majority of which flow into waste management infrastructures (WMIs) at end their life cycles, but little is known about atmospheric releases PFAS from these facilities. In this study, we addressed key issue by investigating 49 PFAS, including 23 ionic 26 neutral precursor potential sources (n = 4; within or adjacent to WMIs) reference sites 2; coastal natural reserve sites) urban rural...
Due to their prevalence in urban contaminated water, the driving factors of organophosphate esters (OPEs) need be well examined, and related ecological impacts should include that transformation products (TPs). Additionally, a robust framework needs developed integrate multiple variables for improving health assessment. Therefore, OPEs TPs stormwater wastewater Hong Kong were analyzed fill these gaps. The results revealed total concentrations positively correlated with area transportation...
Amphibians are sensitive biomonitors of environmental pollutants but reports regarding per- and polyfluoroalkyl substances (PFAS), a class synthetic organofluorine substances, limited. In this study, samples water Chinese toads (Bufo gargarizans) were collected in Chaohu Lake, China. Tissue-specific bioaccumulation characteristics 39 PFAS, including 19 perfluoroalkyl acids (PFAAs), 8 emerging 12 PFAA precursors, investigated, the levels some biochemical indicators determined. The highest...
