Unexpected Polymerization Pathway in the Carbocatalysts/Permanganate Processes for Water Decontamination [0.03%]
Zhengwei Zhou,Yue Wang,Guojie Ye et al.
Zhengwei Zhou et al.
Permanganate (KMnO4) is widely used in water treatment but is often limited by its moderate oxidation potential for the deep decomposition of contaminants. Here, we found that multiple conductive carbocatalysts (e.g., carbon nanotube (CNT),...
Using a Multi-Tracer Approach to Examine Perfluoroalkyl Substance Sources and Dietary Exposure Pathways in Pacific Bald Eagles [0.03%]
Robert Kesic,John E Elliott,Myles Lamont et al.
Robert Kesic et al.
Perfluoroalkyl substances (PFAS) are globally distributed contaminants that bioaccumulate in avian apex predators, yet species-specific bioaccumulation processes and links to dietary sources remain poorly resolved. Using an integrative, mul...
Bacterial Transformation Products from Organophosphate Esters and Their Elevated Environmental Risks in Soil and Groundwater Surrounding a Chemical Industrial Park [0.03%]
Yixiang Chen,Kun Wang,Xinfei Ge et al.
Yixiang Chen et al.
Organophosphate esters (OPEs) are chemicals of emerging concern that pose risks to human and wildlife health. Soil microorganisms transform OPEs into diverse biotransformation products (BTPs), thereby broadening the exposure beyond the pare...

Sana M James et al.
Biogenic volatile organic compounds (VOCs) play important roles in atmospheric chemistry, yet most studies have focused on canopy emissions. Decomposition of forest litter, a major below-canopy VOC source, can substantially influence atmosp...
An Overlooked Chemical Conversion Pathway of Glyphosate: Ferrous-AMPA Complex-Mediated Oxygen Activation [0.03%]
Yiyi Shu,Biao Zhou,Haoqi Zhang et al.
Yiyi Shu et al.
The widespread use of glyphosate (PMG), the most abundant herbicide globally, poses substantial ecological risks owing to the persistence of both PMG and its toxic metabolite, aminomethylphosphonic acid (AMPA). While ubiquitous transition-m...

Rongrong Xuan et al.
Per- and polyfluoroalkyl substances (PFASs) are persistent pollutants that cross the placental barrier, yet their transfer dynamics and developmental impacts remain unclear. We quantified 16 PFASs in maternal serum, cord serum, and maternal...
Optimizing Cryo-Focused Pyrolysis GC/MS for Tracing Soil Organic Matter Across Diverse Ecosystems [0.03%]
Abrar Shahriar,Mavrik Zavarin,Erin E Nuccio et al.
Abrar Shahriar et al.
The cycling of organic matter in terrestrial soils and sediments is central to a range of biogeochemical processes that regulate nutrient cycling, crop productivity, trace gas emissions, and contaminant transport. Pyrolysis-gas chromatograp...

Prakash Dangal et al.
Environmentally Persistent Free Radicals (EPFRs) pose potential environmental and health risks, yet their behavior remains insufficiently characterized. This study investigates the influence of pH on EPFRs activation during redox cycling, f...
Precipitation-Driven Shifts in Organic Sulfur Decomposition and Oxidation State along Rainfall Gradients [0.03%]
Mengqiang Zhu,Than T N Dam,Oliver Chadwick et al.
Mengqiang Zhu et al.
The decomposition of organic sulfur (S) influences S availability to plants and trace metal dynamics in soils. While temperature effects on decomposition rate are known, the influence of precipitation remains less understood. We examined or...
Elevated Temperature Promotes Metal Clearance in Chaeturichthys stigmatias with Glycolysis-Linked Signatures [0.03%]
Jianning Wang,Tao Yang,Haozhong Tian et al.
Jianning Wang et al.
Elevated temperature reshapes physiological processes in aquatic ectotherms, yet how warming influences metal retention and clearance remains insufficiently resolved in fish. Here, we examined temperature-linked variation in tissue metal bu...
