Despite significant progress in understanding carbon persistence and turnover, the underlying mechanisms require further study. A key challenge is visualizing and characterizing the spatial distribution of carbon within intact soil. This study introduces a novel approach to map carbon content at 35 µm resolution and composition at 22 µm resolution in intact environmental samples using synchrotron X-ray spectromicroscopy. X-ray fluorescence maps provided an overview of total carbon distribution, identifying carbon-rich regions. Near-edge X-ray absorption fine structure spectromicroscopy was then used to obtain spatially resolved carbon speciation data within these regions. This method allowed the analysis of relatively large intact samples, of 16 mm in diameter and 15 mm in height, preserving various root and organic matter fragments as well as pores ranging between 35 and 850 µm. Spectral fitting with reference standards revealed distinct spatial patterns of aromatic, aliphatic, and carboxylic carbon compounds associated with different structural features. Aromatic carbon was enriched around root fragments and the soil matrix; while, carboxylic compounds were concentrated at pore–matrix interfaces, indicating a correlation between soil pore structure and carbon chemical composition. This novel approach provides significant insights into the interplay between pore architecture and organic molecular diversity, key factors governing carbon protection and persistence in soils.</p>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"60 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917213","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 chiral neonicotinoids dinotefuran, sulfoxaflor, cycloxaprid, and paichongding, with focus on their chiral characteristics, configuration stability, biological activity, ecological toxicology, and environmental fate. Isomeric separation of chiral neonicotinoids can be achieved by chromatography. The dinotefuran <i>R</i> isomer is less toxic than the <i>S</i> isomer to honeybees and earthworms by a factor of 2.7–145.9, with similar control efficiency of common agricultural pests. The insecticidal activity of (5<i>R</i>,7<i>S</i>)-paichongding are up to 20.1 times higher than that of other isomers, and it is absorbed fastest by crop roots and tends to be preferentially degraded and mineralized in soils. Therefore, formulations containing<i> R</i>-dinotefuran or (5<i>R</i>,7<i>S</i>)-paichongding could decrease ecological damage without compromising food production.

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.

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.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 1","pages":"117 - 138"},"PeriodicalIF":15.0,"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}
