In this study, based on the interaction of NFRs and human serum albumin (HSA), we assessed the differences in potential human accumulation of 8 NFRs including 1,2-Dibromo-4-(1,2-dibromoethyl)cyclohexane (TBECH), tetrabromobisphenol A bis(dibromopropyl ether) (TBBPA-DBPE), 2,4,6-tribromophenol (TBP), pentabromophenol (PBP), tri-n-butyl phosphate (TnBP), triphenyl phosphate (TPP), Tri(2-chloroethyl) phosphate (TCEP), and Tri(1,3-dichloro-2-propyl) phosphate (TDCP). All NFRs could bind to HSA and cause slight damage to its structure, suggesting their potential human accumulation ability. Notably, the binding pocket of site 1 was larger than that of site 2, so TBBPA-DBPE with a larger molecular volume exhibited a preference for binding to site 1 and other NFRs with smaller volume bound to site 2. Binding constant (<em>K</em><sub>A</sub>) analysis revealed that TBP and PBP had strongest potential human accumulation ability (<em>K</em><sub>A</sub>: 6.35 × 10<sup>6</sup>–7.84 × 10<sup>6</sup> L/mol), followed by TnBP, TPP, TCEP, and TDCP (<em>K</em><sub>A</sub>: 3.50 × 10<sup>4</sup>–7.80 × 10<sup>4</sup> L/mol), while TBBPA-DBPE and TBECH presented the lowest ability (<em>K</em><sub>A</sub>: 5.84 × 10<sup>3</sup>–8.05 × 10<sup>3</sup> L/mol). Theoretical calculations demonstrated that the magnitude of <em>K</em><sub>A</sub> was attributed to the molecular volume and the size and distribution of NFRs' molecular surface electrostatic potential (MSEP). TBP and PBP with smaller molecular volumes exhibited evenly distributed positive and negative MSEP, facilitating their entry into the binding site and interact with HSA. In summary, this study elucidates the influence of pollutants' volume and the size and distribution of MSEP on the binding sites and <em>K</em><sub>A</sub>, providing a crucial theoretical basis for understanding the pollutants' potential human accumulation, which contributes to the screening and monitoring of new environmental pollutants.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"963 ","pages":"Article 178542"},"PeriodicalIF":8.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142996675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NNOM has been implicated as a conditioning agent leading to the formation of biofilms such as algae. NNOM is also a responsible in surface waters for facilitated transport of a variety of anthropogenic pollutants. These are NNOM surface-related phenomena, yet the variable surface area and surface composition of NNOM, which can change dependent on shear rate, is not discussed in the literature. NNOM polymer-like dynamics can interact with stream water velocity differences to determine the process and result of aggregation. The fundamental role of post-shear NNOM molecular structure and dynamic aggregation (self-assembly) is examined here alongside fresh (hydrological) versus mined (terrestrial) NNOM. Shear rate can be seen as a change in the velocities of streamlines in hydrology. In this early work, the response to shear rate for three types of NNOM was measured using a stress-controlled rheometer under varying conditions of ionic strength. Samples were studied for rheological response after a variety of pre-shear conditions, and data then coupled with surface composition data from previously reported fluorescence studies. Interestingly, a size class of 5 μm aggregates disappeared when Aldrich humic acid samples were treated with 0.3 M Ca<sup>2+</sup>. Evidence is also presented that the environmental samples flocculated at shear rates up to 400 s<sup>−1</sup>, rather than exhibiting particle breakup, with implications for reducing NNOM surface area. Dynamic response of different NNOM sources was not the same, some sources showing evidence of self-assembly. The molecular response to shear may play an important role in understanding the surface area and composition of NNOM responsible for facilitated transport of pollutants and initiation of biofilms.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"963 ","pages":"Article 178463"},"PeriodicalIF":8.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142996721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By comparing with the free enzymes, the immobilized enzymes were found to have better thermal stability, pH adaptability, reusability, and storage stability. In addition, combined with the LC-MS analysis of the removal products, three removal pathways were postulated, including the reactions of β-lactam ring cleavage, decarboxylation, demethylation, deamidation, and oxidation. Finally, the toxicity of the removal products was evaluated using ECOSAR software, and the results showed that the intermediate products had low toxicity.

Unhealthy trees were enriched selectively in certain plant growth promoting microorganisms such as several ectomycorrhizal fungi (<em>Clavulina</em>) and <em>Streptomyces</em>, while other beneficial microorganisms (<em>Micromonospora</em>) were more abundant in unaffected pines. The rhizosphere of unhealthy trees was richer in secondary metabolites involved in plant defense than healthy pines, while the opposite trend was detected in root samples.

However, the significance of potassium (K), one of the three major nutrients (nitrogen, phosphorus, and K) essential for plant growth, has often been overlooked, particularly in the context of saltmarshes where the mechanisms of K transport via porewater exchange remain poorly understood. To address this knowledge gap, we conducted field observations and laboratory analysis, and developed a <sup>222</sup>Rn mass balance model to quantify K fluxes via porewater exchange under physical, biological, and anthropogenic drivers. Our findings revealed that saltmarshes function as highly effective K sinks, with porewater exchange rates ranging from 12.2 to 44.5 cm d<sup>−1</sup> and related K fluxes spanning −122 to −1260 mmol m<sup>−2</sup> d<sup>−1</sup>. Interestingly, wet season K fluxes were found to be ∼4.3 times higher than those observed during the dry season. Moreover, we observed that wet season K fluxes peaked during the neap tide, while dry season K fluxes reached their maximum during the spring tide. This suggests that K transport via porewater exchange is influenced by both crab burrow bioturbation and spring-neap exchange mechanisms. In addition, anthropogenic activities, such as biomass burning, also impact K dynamics in addition to physical and biological drivers. Overall, our study highlights the pivotal role of porewater exchange in driving the K cycle within saltmarshes. This exchange mechanism not only facilitates plant growth but also contributes to important mineralogical processes, including cation exchange and reverse weathering, occurring within the saltmarsh ecosystems.
