The significant excretion of LORA (approximately 40 % in urine and 42 % in feces) contributes to its frequent occurrence in wastewaters and subsequently in aquatic environments, where it is typically detected at ng/L levels. This study investigates the possible formation of LORA degradation byproducts (DBP) under neutral hypochlorination, a common water disinfection process. Eight DBPs were generated, and they were isolated via HPLC and fully characterized by nuclear magnetic resonance (NMR) and mass spectrometry (MS). Among them, 5 compounds have been reported here for the first time. Formation pathways were proposed for all identified DBPs. The acute and chronic toxicity of LORA and its DBPs was evaluated using ecotoxicological assays with freshwater species representing different trophic levels: the microalga Raphidocelis subcapitata (primary producer) and the rotifer Brachionus calyciflorus (primary consumer). Acute effects of the DBPs occurred at concentrations of hundreds of μg/L. Regarding chronic toxicity, algae showed low sensitivity to both LORA and its derivatives, while rotifers were more susceptible to the DBPs, with effective concentrations ranging from a few ng/L to hundreds of ng/L range. Conversely, LORA induced only a 38 % effect at 2000 ng/L, indicating higher chronic toxicity of DBPs compared to the parent compound. These results underscore the environmental relevance of LORA DBPs, which may pose a higher chronic risk to aquatic organisms than the parent compound, especially under typical water treatment conditions.</p>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1004 ","pages":"180753"},"PeriodicalIF":8.0,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145353443","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}

Therefore, AE can cause significant errors in quantitative retrieval of surface reflectance in high-contrast environments and further derived information, such as pixel-based chlorophyll-a concentration. This review aims to make the niche topic of AE in optical remote sensing more accessible to a broader audience.

We applied both methods to a case study of the Osterseen Lake District south of Munich (Germany), demonstrating their application and effectiveness in correcting AE in the near-infrared (NIR) while identifying room for improvement in the visible light (VIS).

Concerns about CIP are ascribed to its persistence and incomplete degradation in the environment, which could lead to the spread of drug-resistant bacterial strains. Adsorption of CIP has played a remarkable role in the treatment of CIP-laden (waste)water, and the role of clay adsorbents has increasingly emerged. However, limited studies have been reported on the use of clay-based adsorbents for CIP adsorption, compared to the use of other adsorbents. Second, the lack of understanding of interaction pathways and the effectiveness of clays might limit its practical application in wastewater treatment. Given this gap, this paper present state-of-the-art review on the adsorption of CIP using clay-based adsorbents. Our findings revealed that composite of graphene oxide-kaolinite and activated montmorillonite-kaolin are synergistically effective to remove CIP sorption with demonstrated sorption capacities of 408.16 mg/g and 344.82 mg/g, respectively. Bentonite-based composites showed the best performance, particularly ZnO/CuO-bentonite, with 451 mg/g experimentally and about 1249.3 mg/g calculated capacity, with a removal efficiency of nearly 99 %. Overall, pH was found to play dominant role in controlling CIP adsorption as well as the electrostatic attraction as dominant mechanism of uptake. Isotherm modelling suggested that the best fit model was Langmuir isotherm (r<sup>2</sup>>0.96-0.99) which confirms chemisorption as the dominant mechanism.

To address this knowledge gap, this study investigated agricultural systems in naturally Se-Cd-rich areas within the Wumeng Mountain region of Guizhou, China. Samples of roots, stems and leaves, along with the corresponding rhizosphere soils of corn (Zea mays L.) in the grain-filling stage, were collected and analysed for Se and Cd concentrations and speciations. Results demonstrated significant inverse relationships among rhizosphere-soil Cd bioavailability, Cd accumulation in corn plant compartments, and increasing bioavailable Se:Cd molar ratios in soil (p < 0.05). Notably, the soil Se:Cd molar ratio was inversely correlated with Cd translocation from soil to roots (p < 0.01) while showing no significant effects on aboveground translocation (root-to-stem and stem-to-leaf, p > 0.05). These outcomes suggest that the soil Se:Cd molar ratio primarily regulates Cd accumulation at the soil-root interface, with limited impact on subsequent translocation within plant compartments. Moreover, the transformation of Cd into Cd-SeCys and Cd-SeMet occurred more frequently in the stem and leaf compared with that in the root. Furthermore, the underlying mechanism was conceptualised as comprising 'three barriers': SeCd complex formation in the rhizosphere (Barrier 1), Cd sequestration by the selenohydryl group (-SeH) in plant cells (Barrier 2) and Cd inhibition by phloem and nodes (Barrier 3). These findings support the use of Se:Cd molar ratios as indicators for sustainable crop safety in SeCd co-contaminated regions. This study advances the understanding of the potential mechanisms underlying the Se:Cd molar ratio and its influence on Cd toxicity in natural environments. Based on these findings, the Se:Cd molar ratios serve as an effective indicator for sustainable management of Cd contamination in agriculture.</p>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1004 ","pages":"180758"},"PeriodicalIF":8.0,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145353328","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}
