In-sewer stability assessment of 140 pharmaceuticals, personal care products, pesticides and their metabolites: Implications for wastewater-based epidemiology biomarker screening

Environment International, Journal Year: 2024, Volume and Issue: 184, P. 108465 - 108465

Published: Jan. 30, 2024

The monitoring of pharmaceuticals, personal care products (PCPs), pesticides, and their metabolites through wastewater-based epidemiology (WBE) provides timely information on pharmaceutical consumption patterns, chronic disease treatment rates, antibiotic usage, exposure to harmful chemicals. However, before applying them for quantitative WBE back-estimation, it is necessary understand stability in the sewer system screen suitable biomarkers thereby reducing research uncertainty. This study investigated in-sewer 140 typical PCPs, across 15 subcategories, using a series laboratory sediment biofilm reactors. For first time, results 89 these compounds were reported. Among target compounds, 61 demonstrated high all reactors, while 41 significantly removed merely by processes. exhibiting notable attenuation, influence processes was generally more pronounced than biofilm, due its stronger microbial activities diffusion or adsorption Adsorption emerged as predominant factor causing biomarker removal compared biodegradation diffusion.

Response of Microbial Communities to Antiviral Drug Stress in Surface Water in Beijing

Water, Journal Year: 2025, Volume and Issue: 17(1), P. 118 - 118

Published: Jan. 4, 2025

The environmental persistence of antiviral drugs poses serious safety hazards to aquatic ecosystems through their selective pressure on microorganisms, yet the understanding drugs’ impact microbial community structures remains limited. In this study, surface water samples from Beijing were analyzed for drug concentrations using UPLC-MS/MS, and abundance was assessed via 16S amplicon sequencing. Employing these methods, we investigated mechanisms which may exert ecological risks communities. Our findings reveal that significantly increase Enhydrobacter Nitrospira microbiota. concentration DNA polymerase inhibitor is positively correlated with Peredibacter, Enterococcus, Aeromonas, Aquabacterium, Alloprevotella, Ruminococcus.

Efficient Removal of Emerging Contaminant Sulfamethazine in Water by Fe₂O₃: Roles of Morphological Features and Oxygen Vacancies

Applied Organometallic Chemistry, Journal Year: 2025, Volume and Issue: 39(3)

Published: Feb. 16, 2025

ABSTRACT The inability to recycle Fenton reagents and a narrow pH range restricts hematite (Fe 2 O 3 ) application in the actual photo‐Fenton system. engineering of surface structures is identified as an effective approach for enhancing activity material. In this work, three different morphologies (nanosheet, cube, ring) Fe materials containing oxygen vacancies (OVs) were synthesized by hydrothermal method, novel system degradation sulfamethazine was examined. presence oxalic acid, /oxalic acid heterogeneous catalytic demonstrated situ generation H facilitated Fenton‐like reactions. as‐prepared nanosheet‐Fe showed highest efficiency. free radical capture experiment investigated using sacrificial agents, results suggested that superoxide radicals principal active species involved. Ecotoxicity assessments utilizing toxicity prediction software assessed reaction intermediates generated during via quantitative structure–activity relationship indicating these exhibited reduced developmental toxicity. possible pathways mechanism synergistic effect between proposed. This research presents strategy design synthesis photocatalysts with various vacancies, suitable catalysis related environmental contexts.
