However, the key parameters governing the reactivity of RHS via the SET pathway remain unclear. This study comprehensively investigated the SET pathway of the RHS with 51 aromatic contaminants by quantum-chemical calculations. The calculated free energy changes of the SET pathway (Δ<i>G</i>_aq,SET^R) followed the order Cl^• &lt; Cl₂^•– &lt; Br^• &lt; Br₂^•–, which was consistent with the order of their reduction potentials. However, the free energy of activation of the SET pathway (Δ<i>G</i>_aq,SET^⧧) followed a different order of Cl^• &lt; Br^• &lt; Cl₂^•– &lt; Br₂^•–, which agreed with the order of their rate constants. This inconsistent trend between Δ<i>G</i>_aq,SET^R and Δ<i>G</i>_aq,SET^⧧ for RHS reactions was attributed to the difference in reorganization energy, which is essentially related to the vertical electron affinity and radius of RHS. Therefore, the rate constants of SET reactions of RHS depend not only on their reduction potential but also on their vertical electron affinity and radius. These findings unravel the key factors determining the reactivity of RHS via the SET pathway and have profound implications for understanding other SET processes in water.</p>","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 6","pages":"761–767 761–767"},"PeriodicalIF":8.9,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144238352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study investigated the compositions, formation pathways, and sources of OSs at a coastal site of the South China Sea in summer. Thirty-three OS species were quantified by using an UHPLC-Orbitrap MS and were assessed under marine and terrestrial air mass origins. iOSs (isoprene-derived OSs) ranked the highest, followed by C2/C3 OSs (OSs with two or three carbon atoms). The formation of iOSs was influenced by aerosol pH and their major precursor (isoprene), with photochemical processes playing a significant role in terrestrial transport. Different from urban conditions, sea breezes favored the formation of 2-MAS (C₄H₇O₇S^–) over 2-MTS (C₅H₁₁O₇S^–) even under low NO_<i>x</i> levels, mainly attributed to the high temperature and dominance of aqueous oxidation. Compared to terrestrial transport, the formation of C2/C3 OSs was more favored than that of iOSs under the influence of sea breezes. Marine biogenic emission was quantified as an important source of C2/C3 OSs. This study enhances our understanding of the influence of both terrestrial and marine factors on the formation pathways of atmospheric OSs and emphasizes the significant contribution of marine biogenic sources to OSs.</p>","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 6","pages":"739–746 739–746"},"PeriodicalIF":8.9,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144238734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Previous high-throughput phenotypic profiling (HTPP) studies using the Cell Painting assay in the RTgill-W1 rainbow trout cell line have demonstrated that 6PPD-quinone toxicity occurs at much lower concentrations than the 6PPD parent molecule, which is consistent with available <i>in vivo</i> toxicity data in rainbow trout. Current research efforts include identifying alternative antiozonant compounds to potentially replace 6PPD in tire manufacturing. To fill bioactivity data gaps for potential 6PPD alternatives, 18 compounds including other substituted <i>p</i>-phenylenediamines (PPD) and PPD-quinones were assayed using HTPP in RTgill-W1 cells. 7PPD-quinone and 77PD-quinone produced changes in cellular phenotype similar to those of 6PPD-quinone at comparable concentrations. IPPD-quinone produced changes in cellular phenotype at higher concentrations than 6PPD-quinone, with a phenotypic profile that was most similar to its parent molecule IPPD. These findings suggest that 7PPD-quinone and 77PD-quinone may exhibit similar effects in rainbow trout and potentially other 6PPD-quinone sensitive salmonids. In contrast, IPPD may be less toxic to salmonids than 6PPD, given the relative lack of bioactivity of IPPD-quinone compared to 6PPD-quinone.</p>","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 6","pages":"695–701 695–701"},"PeriodicalIF":8.9,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144238928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
