Confined Fe(III) in carbon nitride shifted peroxymonosulfate activation from radical to high-valent iron pathways for efficient dioxin degradation
Fe-doped carbon matrices have garnered significant attention as peroxymonosulfate (PMS) activators for the removal of refractory organic pollutants. However, the role of Fe dopant in PMS activation remains unclear, especially concerning the relative contributions and reaction pathways of…

Oxidation of polyaniline-derived carbon using microwaves for adsorptive removal of pharmaceuticals with an amino group
Carbonaceous materials, especially oxidized ones, have been frequently used as adsorbents. Oxidation of carbons has usually been carried out using ammonium persulfate/H2SO4 solution under electric heating. In this work, polyaniline-derived carbons were oxidized with both the conventional method and…

Versatile TOP assay surrogates for evaluating oxidation efficiency in complex environmental samples
Accurate assessment of total per- and polyfluoroalkyl substance (PFAS) contamination remains limited because conventional targeted analyses do not capture unknown precursor compounds. The total oxidizable precursor (TOP) assay has been widely used to address this gap; however, previous studies have…

Synergistic enhancement of uranium phytoremediation by a PGPR consortium (Microvirga sp. M2 and Bacillus cereus B6) in Sorghum sudanense: From pot to field evidence
Uranium (U) contamination poses serious environmental risks, but phytoremediation efficiency is often limited. This study evaluated single and combined inoculation of two U-tolerant plant growth-promoting rhizobacteria (PGPR) strains (Microvirga sp. M2 and Bacillus cereus B6) on Sorghum sudanense…

Evaluation of capping technologies for remediation of PFAS-contaminated sediments
Per- and polyfluoroalkyl substances (PFAS), including perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), and perfluorobutanesulfonic acid (PFBS), are a critical class of emerging environmental contaminants. The continuous release of PFAS from land surfaces into water creates…

Enhanced PFAS remediation of AFFF-contaminated soil by foam injection
Aqueous film-forming foams (AFFF) are extensively used in firefighting and are composed of a mixture of per- and polyfluoroalkyl substances (PFAS), including anionic, cationic, and zwitterionic compounds. Remediating soils contaminated by these emerging compounds is challenging due to their…

Field-scale evidence of PFAS pollution potential from municipal landfills
Leachate from municipal landfills is a major source of per- and polyfluoroalkyl substances (PFAS) to groundwater. This study presents field-scale evidence of PFAS generation, release, and downward migration in a closed landfill comprising a 15 m waste body overlying a 16 m sandy unsaturated zone…

Di(2-ethylhexyl) phthalate exposure disrupts intestinal microbiota and activates immune signaling pathways in zebrafish intestine
Di(2-ethylhexyl) phthalate (DEHP), a common plasticizer, exhibits environmental persistence and multisystem toxicity. With plastic production continually rising, China’s annual output exceeded 77 million tons in 2024, reflecting a 2.9 % year-on-year increase (Ministry of Industry and Information…

Granular activated carbon reduces PFAS bioavailability and protects ant colony growth in soil
Per- and polyfluoroalkyl substances (PFAS) are persistent contaminants that pose risks to ecological and human health. Soil stabilisation using sorbents such as granular activated carbon (GAC) can reduce PFAS mobility and bioavailability. Previous studies have focused on plants and earthworms, but…

Copper and cadmium toxicity affecting in vitro growth and Scopelophila cataractae development
The effects of copper (Cu) and cadmium (Cd) accumulation on growth and development of Scopelophila cataractae (Mitt.) Broth., Pottiaceae, were investigated over 24 weeks. Moss samples were grown on modified hydroponic medium supplemented with Cu and Cd. Cu markedly promoted the transition from…

Development of a silica gel chromatography-based cleanup method for quantification of polystyrene nanoplastics in tissue samples via pyrolysis–GC/MS
Nanoplastics (NPs) are cause for increasing concern due to their ability to cross biological barriers, enhanced reactivity, and potentially greater toxicity than microplastics. However, their quantification in biological samples such as animal tissues remains challenging, primarily due to complex…

Emerging contaminants in stormwater: Tire-derived chemicals, pharmaceuticals, and heavy metals detected in a United Arab Emirates extreme weather event
Climate change is associated with the intensification of weather patterns, including extreme weather events of historically arid regions such as the United Arab Emirates (UAE). On April 16–17, 2024, the UAE experienced a severe storm with unusually heavy precipitation, which resulted in widespread…

A laser-enabled low carbon emission pyrometallurgical approach to recycle Li-ion batteries via silicothermic reductions
In response to the growing shift from graphite to silicon in Li-ion battery anodes, we propose a novel low-carbon pyrometallurgical recycling method that uses silicon as the reducing agent. Silicon was chosen as the reductant because, as the emerging high-capacity anode material, it not only…

Mesophilic compostability of polylactic acid and the associated microbiome as revealed by metagenomics
Polylactic acid (PLA), the most popular bioplastic, has high sustainability potential as it is bio-sourced and also harbors biodegradability. A form of its biodegradability is via composting, and it was previously established that thermophilic temperatures are needed for PLA breakdown in composts…

PFAS in biosolids: Insights into current and future challenges
Biosolids, valued as nutrient-rich soil amendments, are now approached cautiously by farmers due to growing public concern, and increasingly stringent and varying per- and poly-fluoroalkyl substances (PFAS) regulatory standards across jurisdictions. PFAS concentrations in biosolids vary widely…

Substantially underestimated PFAS pollution in diverse Ghana’s land-use types revealed by a refined TOP assay
Per- and polyfluoroalkyl substances (PFAS) research in developing countries has largely focused on imported sources such as e-waste, but contributions from local land-use activities remain poorly understood. This study selected Ghana as a model to investigate PFAS contamination in sediments from…

Ingestion of microplastics during chewing gum consumption
Chewing gums typically contain plant-based or synthetic plastic polymers to improve their texture and flavor retention. These polymer fragments or microplastics can be released into the environment when disposed of improperly or ingested while chewing gums. Yet, how many microplastics a person may…

Micropellets of Pleurotus ostreatus for copper removal: Influence of nutritional conditions and laccase activity on adsorption
Pleurotus ostreatus has emerged as a promising model for heavy metal bioremediation. Given the known role of laccases in copper oxidation, it was hypothesized that higher laccase activity would correlate with increased copper removal. This study evaluated how the composition of the culture medium…
