In particular, mud crabs, with an annual global landing of over 100,000 metric tons, are crucial for the economic livelihoods and food security of millions of small-scale fishers in Southeast Asia. Here, we review the impact of pollutants on mud crab populations in mangrove ecosystems, with emphasis on pollutant sources, toxic effects on crabs, and remediation using microbes and biochar. Pollutants include microplastics, per- and polyfluoroalkyl substances, pesticides, polycyclic aromatic hydrocarbons, and heavy metals. Pollution originates from agricultural runoff, industrial discharges, mining activities, urbanization, and domestic waste. We present the use of biochar for pollutant remediation and enhancing carbon sequestration. We observe that heavy metals, pesticides, and microplastics induce oxidative stress, disrupt antioxidant defense mechanisms, and impair the growth, reproduction, and survival rates of mud crabs. Microbial bioremediation can remove more than 90% of polycyclic aromatic hydrocarbons. Biochar application reduces by 87% the bioavailability of heavy metal in contaminated soils.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"83 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874097","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}

Production of petrochemical plastics is also reaching 400 million metric tons in 2023. The lack of effective thermochemical processes for converting wet feedstocks and complex residues such as plastics is calling for hydrothermal gasification as an efficient approach to producing syngas. The demand for hydrogen production through greener approaches is also rising to compete with the commercial steam reforming of natural gas. Here, we review the conversion of biomass and plastics by hydrothermal gasification into hydrogen-rich syngas with a focus on the process parameters influencing the conversion of a variety of feedstock types. Parameters influencing hydrothermal gasification of biomass and plastics include temperature, pressure, reaction time, feedstock concentration, catalysts and reactor types. Several synergetic effects also influence product distribution during the co-processing of biomass and plastics during hydrothermal gasification. Processes that impact biomass conversion to syngas are hydrolysis, water–gas shift, methanation, hydrogenation, steam reforming and polymerization.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"20 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849320","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}

Here we review the use of advanced oxidation processes-based treatment of water, wastewater, and sludge, with focus on singlet oxygen production, reactivity mechanisms, and applications. Processes for single-oxygen production include photochemical production, decomposition of hydrogen peroxide, ozonides, endoperoxides, and sulfate radical-based advanced oxidation. Singlet oxygen is one of the main non-radical reactive oxygen species that are generated during advanced oxidation processes. It is less reactive but highly selective toward electron-rich organic compounds, compared to hydroxyl and sulfate radicals. When generated in large quantities, singlet oxygen can be the dominant reactive oxygen species responsible for the degradation of targeted pollutants. Singlet oxygen is less affected by water matrix components including dissolved organic matter and scavenging by anions.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"16 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816237","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}

Iron-modified biochar, synthesized from agricultural waste, is proposed as an efficient and sustainable media for removal of ciprofloxacin and amoxicillin from wastewater. Iron-modified biochar was synthesized using a simple pyrolysis process with corn and ferrous sulfate as feedstock. Adsorbents were characterized by fourier transform infrared spectroscopy, X-Ray diffraction, and scanning electron microscopy. Removal performance of antibiotics was evaluated under different conditions, including antibiotic dosage, concentration of hydrogen peroxide, pH, and amount of humic acid. The results demonstrated high removal efficiencies of 87% for ciprofloxacin and 83% for amoxicillin within 25 min. Mechanistic studies revealed the generation of hydroxyl radicals (•OH) and singlet oxygen (1O₂), and confirmed the activation of hydrogen peroxide in the system. These findings highlight the potential of iron-modified biochar as a sustainable and effective catalyst for antibiotic removal, offering a promising solution for reducing pharmaceutical contamination in wastewater.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"417 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142598235","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}

Long-lived photo-oxidants are reactive species formed when the chromophoric dissolved organic matter absorbs sunlight, and they are involved in the degradation of contaminants. Previous works identified long-lived photo-oxidants with phenoxy radicals, which could be formed upon oxidation of natural phenols by the excited triplet states of chromophoric dissolved organic matter. Here, we generated reactive phenoxy radicals by direct ultraviolet-A photolysis of 2-nitrophenol and 4-nitrophenol. We measured the second-order rate constants for reaction of these phenoxy radicals with 2,4,6-trimethylphenol, a model electron-rich phenol. Results show rate constants of 9.39 × 108(M−1s−1) for the 2-nitrophenoxyl radical, and 1.56 × 108(M−1s−1) for the 4-nitrophenoxyl radical. These values are slightly lower than the typical rate constant of the reaction between 2,4,6-trimethylphenol and the excited triplet states of chromophoric dissolved organic matter, of 3 × 109(M−1s−1). This means that 2,4,6-trimethylphenol would not be degraded to comparable extents by the excited triplet states of chromophoric dissolved organic matter and by long-lived photo-oxidants, if long-lived photo-oxidants were generated solely by the triplet states of chromophoric dissolved organic matter. Overall, findings suggest the occurrence of new pathway involving the direct photolysis of organic matter phenols that generates long-lived photo-oxidants.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"10 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142580235","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}
