Boosted antibiotic degradation using magnetite nanoparticles doped ultrafine activated charcoal powder to activate HO: Insights into mechanisms and competitive kinetics.
Environ Res

Department of Civil and Environmental Engineering, School of Environment and Society, Institute of Science Tokyo, Meguro-ku, Tokyo, 152-8552, Japan.
The treatment of antibiotic wastewater often faces the challenge of simultaneously and effectively degrading multiple components under complex conditions. To address this challenge, magnetite nanoparticles doped ultrafine activated charcoal powder (MNPs/UACP), which effectively catalyzed the decomposition of HO into •OH and HO•, was prepared using chemical co-precipitation. Under optimum conditions (i.

Antibiotics and antibiotic resistance genes (ARGs) are severe refractory pollutants in water. However, the effect of an intermittent electrical stimulation on the removal of antibiotics and ARGs from saline wastewater remains unclear. An anaerobic-aerobic-coupled upflow bioelectrochemical reactors (AO-UBERs) was used to treat tetracycline (TC) and quinolone (QN) in saline wastewater.

A new, effective powdered adsorbent (CMCFe) for removing oxytetracycline (OTC) was synthesized successfully in an acidic environment using a thermal fusion technique. CMC-Fe underwent comprehensive SEM, EDS, FT-IR, XRD, XPS, TGA, and BET analyses before and after adsorbing OTC. These studies systematically examined preparation variables such as CMC and FeCl ratios, acetic acid quantity, reaction duration, and temperature.

Department of Implementation Science, Division of Public Health Sciences, Wake Forest University School of Medicine, Winston-Salem, NC, USA.
Background: Over-the-counter (OTC) naloxone became available for sale at community pharmacies in September 2023. This study examines whether naloxone availability and cost are associated with pharmacy type (independent vs chain), pharmacy rurality, and their interaction.
Methods: Using a cross-sectional secret shopper study design, data were collected by phone from a stratified random sample of 600 community pharmacies in North Carolina from November 2023 to January 2024.
Ecodevelopmental influences on latent classes of substance use among urban American Indian adolescents.
J Ethn Subst Abuse
January 2025
Arizona State University, Tempe, Arizona.
Unlabelled: The large majority (over 70%) of American Indian adolescents who reside in cities rather than tribal lands or rural areas report relatively earlier onset of substance use and more harmful associated health effects, compared to their non-Native peers.
Objective: This study investigated multilevel ecodevelopmental influences on empirically derived patterns of substance use among urban American Indian adolescents.
Method: Data came from 8th, 10th, and 12th grade American Indian adolescents ( = 2,407) in metropolitan areas of Arizona.
