Total I concentrations in 26 seaweed samples from four species ranged from 52.4 to 1322 mg/kg of dry weight. The I RBA varied from 18.5% to 89.0%, significantly influenced by inorganic I percentage (r = 0.50, p < 0.01) and total dietary fiber contents (r = −0.28, p < 0.05) in seaweeds. The I bioaccessibility varied among species and methods and were affected by the pH of gastric solution, as well as the structural changes in seaweed during in vitro extraction. Correlation analysis demonstrated that PBET was the best predictor for I RBA (R2 = 0.64). These results developed an appropriate in vitro method for predicting I bioavailability in seaweeds, which is highly beneficial for the accurate assessment for I dietary intake.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"21 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809843","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}

However, environmental exposure routes from the associated medicinal herb cultivation fields have received little attention. We reveal through liquid chromatography-tandem mass spectrometry analysis of over 400 soil samples collected from three different Aristolochiaceae herb cultivation fields that AAs, which are nephrotoxic and carcinogenic, and aristoloxazines (AXs), a family of recently identified neurotoxic and genotoxic AA analogues, are widespread pollutants in these areas. In particular, aristoloxazine C was detected for the first time in the environment and was found in 318 out of 320 soil samples, at concentrations as high as 2.8 mg/kg, from an Asarum heterotropoides cultivation field. We show that in fact AXs are ecotoxic, inhibiting plant growth and significantly reducing the soil microorganism population. With the extensive cultivation of Aristolochiaceae herbs in order to meet their market demand, we believe our study points to an important environmental hazard that may place food crops and non-AA/AX-producing medicinal herbs at risk of AA/AX contamination.

In this study, we investigated typical electroplating parks in China and conducted the first full-scale removal of PFAS from chromium-plating wastewater using pore-enlarged granular activated carbon (GAC) and hydrophobic anion exchange resin (AER). The results showed that 6:2 fluorotelomer sulfonate (6:2 FTS) gradually replaced perfluorooctanesulfonate (PFOS) in China’s electroplating industry. The conventional reduction-sedimentation process hardly removed 6:2 FTS from chromium-plating wastewater, while the special air flotation process resulted in over 60% of PFOS entering the chromium sludge cake. Based on the full-scale evaluation, GAC and AER adsorption were feasible technologies for removing PFAS from chromium-plating wastewater, among which AER had higher adsorption capacity and removal efficiency for PFAS but poorer selectivity for 6:2 FTS than for PFOS. It is estimated that GAC and AER adsorption have the potential to reduce the discharge of PFAS by 5030–8000 kg/year in China.

However, the interference from chlorine ions (Cl–) can generate reactive chlorine species (RCS), potentially leading to the production of undesirable chlorinated byproducts. A novel approach involving the cathodic oxygen reduction reaction (ORR) for in situ H2O2 production has emerged as a promising strategy to counteract this issue. This study systematically investigated the dynamics and transformation of RCS and reactive oxygen species (ROS) in an ORR/chloride-containing EO (EO-Cl) system, elucidating their respective roles in organic removal and chlorinated byproduct minimization. Distinct generation rates and patterns were observed for free chlorine and H2O2 in the ORR/EO-Cl system. The rapid generation of free chlorine at the anode quickly reached a dynamic equilibrium, which contrasted with the moderate, continuous cathodic production of H2O2, resulting in considerable H2O2 accumulation over time. This difference established kinetics-driven ROS and RCS formation and distribution, influencing the subsequent organic degradation process. Three distinct stages were identified in the degradation process. In stage I, free chlorine was the primary species, along with reactive species including Cl2•–, 1O2, ClO•, HO•, and Cl•. In stage II, the gradual accumulation of H2O2 consumed free chlorine, favoring the formation of 1O2 and HO•. In stage III, excessive H2O2 quenched the free radicals. Insights into these multistage mechanisms reveal that the rapid degradation of chlorinated byproducts by 1O2 and HO• occurs in stage II of the ORR/EO-Cl system.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"14 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809848","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}

While the existence of free radicals in aged plastics has been known for over half a century, only recently has significant research on a new type of environmentally risky substance, namely environmentally persistent free radicals (EPFRs), present in aged MPs and their environmental effects, been started, but it is still in its infancy. To address these issues, this work examines EPFR generation on MPs and their environmental effect by reviewing publications from 2012 to 2023. The aging processes and mechanisms of MPs in the environment are first summarized. Then, the occurrence and formation mechanisms of EPFRs on aged MPs are specifically discussed. Additionally, the reactivity of EPFRs on aging MPs and their influencing factors are comprehensively considered, such as their physicochemical properties, oxygen content, and coexisting substances. Due to their reactivity, EPFRs can interact directly with some substances (e.g., p-nitrophenol and proteins, etc.) or induce the generation of reactive oxygen species, leading to diverse environmental effects, including pollutant transformation, biotoxicity, and health risks. Finally, research challenges and perspectives for EPFRs formation on aging MPs and related environmental implications are presented. Given the environmental fate and risk of MPs-EPFRs, our urgent call for a better understanding of the potential hazards of aged MPs is to help develop a sustainable path for plastics management.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"233 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804578","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}

In an increasingly populated world with growing food demands, a precise and high-resolution spatial prediction of agricultural N2O emissions becomes essential in reducing global emissions. In this study, an integrated assessment model coupled with the land cover downscaling module is employed to predict crop-specific N2O emissions at a 0.05° resolution under various SSP-RCP scenarios from 2025 to 2100. Our findings show that global agricultural N2O emissions will peak around 2065, ranging from 5.2 to 6.6 Tg N a–1. Corn cultivation is the primary N2O contributor, while rice production will produce fewer emissions and peak before 2025. The emission hotspots are concentrated in western Europe, India, eastern China, and the west coast and east-central region of the USA. By 2100, the crop-specific N2O emissions in China are predicted to decrease below the levels observed in 2015, while the emissions in the USA and India may double in some socio-economic pathways. Our projection of N2O emission patterns is supportive of implementing targeted policies and strategies to achieve global emission reduction targets.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"10 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804635","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}

However, accurately quantifying regional rice methane emissions is often challenging due to highly heterogeneous emission fluxes and limited measurement data. This study attempts to address this issue by quantifying regional methane emissions from rice cultivation with a high-resolution inversion of satellite methane observations from the Tropospheric Monitoring Instrument (TROPOMI). We apply the method to the largest rice-producing province (Heilongjiang) in China for 2021. Our satellite-based estimation finds a rice methane emission of 0.85 (0.69–1.03) Tg a–1 from the province or an average emission factor of 22.0 (17.8–26.6) g m–2 a–1 when normalized by rice paddy areas. The satellite-based analysis reveals a 2 to 4 times lower bias in widely used global and national inventories, which lack up-to-date regional information. The inversion reduces the uncertainty of regional rice emissions by 73% relative to bottom-up estimates based on field flux measurements. The satellite inversion also shows that the highest rice methane emissions occur in June during the tillering stage of rice, decreasing toward ripening, indicating that the predominant water management practice in the region involves drainage and intermittent flooding after initial flooding. Process-based modeling further suggests that this practice can lead to a reduction of methane emissions by more than 50% compared to continuous flooding of rice paddies and natural wetlands.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"15 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810013","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}

Flue gas from steam injection boilers typically contains 10–15% CO2 and 80–85% N2, both of which serve as effective gas displacement agents. Injecting flue gas or CO2/N2 mixtures into reservoirs can reduce carbon emissions, sequester CO2, and enhance recovery. Therefore, this study proposes a concept of enriching rather than capturing flue gas for storage, with a focus on how N2 as an impurity affects the safety of CO2 storage. This study examines interactions between gas mixtures with varying CO2 enrichment rates (with N2 impurities) and minerals. It performs microarea analyses of aged rocks using ultradepth-of-field microscope and atomic force microscopy (AFM), assesses calcite wettability via contact angle tests, and evaluates CO2 storage column height under experimental conditions. Results indicate that with a CO2 enrichment of at least 50%, adding N2 creates additional dissolution pits on calcite surfaces. The calcite matrix exhibits optimal water-wettability at 50–75% CO2 enrichment, facilitating greater CO2 storage column heights. This suggests coinjecting N2 and CO2 can enhance long-term CO2 storage safety and reduce capture costs.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"21 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810010","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}

ChemNTP integrates a comprehensive representation of chemical structures and biological targets, improving upon traditional methods that are limited to single targets and mechanisms. By leveraging these structural representations, ChemNTP enables rapid screening across 199 potential neurotoxic targets or key molecular initiating events (MIEs).

Additionally, ChemNTP’s attention mechanism highlights critical residues in binding targets and key functional groups or atoms in molecules, offering insights into the structural basis of interactions. Experimental validation through in vitro enzyme activity assays and molecular docking confirmed the binding of eight polybrominated diphenyl ethers (PBDEs) to acetylcholinesterase (AChE).
