Pharmaceuticals in the environment are a global concern, with studies all continents highlighting their widespread occurrence and potential ecological impacts, revealing presence, fate, associated risks aquatic ecosystems. Despite typically occurring at low concentrations (ranging from ng/L to µg/L), advancements analytical methods more sensitive equipment have enabled detection of higher number pharmaceuticals. In this study, surface wastewater samples were extracted using solid phase extraction analyzed ultra-high-performance liquid chromatography tandem mass spectrometry. Among therapeutic classes investigated, nonsteroidal anti-inflammatory drugs/analgesics, antibiotics, psychiatric drugs showed detected Concentrations ranged below method limit (<MDL) 3.20 µg/L (caffeine) <MDL 639 (hydroxyibuprofen) 2018, 0.848 (diclofenac) 53.0 2019 for river water samples. Temporal analysis an increase sum pharmaceutical over study years, importance monitoring pharmaceuticals accumulation time.

Heterogeneous catalyst-mediated sulfate radical-based advanced oxidation processes (SR-AOPs) showed excellent performance during antibiotics degradation. Spinel was a promising catalyst for SR-AOPs, but the secondary contamination due to metal ions leaching needed be addressed. And destruction of structure could lead reduction catalytic activity and difficulty recovery. Thus, novel nitrogen-doped carbon (NC)-supported CoFe

Abstract Pharmaceuticals as an important group of contaminants emerging concern (CECs) are unintentionally discharged into the aquatic environment due to lack advanced treatment classical wastewater plants (WWTPs). Therefore, detection and monitoring studies pharmaceuticals personal care products (PPCPs) in getting more well definition their ecological risks ecosystem. To conduct these successfully, it is necessary develop sensitive, robust, selective, reliable methods be able analyze PPCPs. This study was carried out biological WWTP (BWWTP) Erzurum City, Türkiye, investigate efficiency plant assess for Karasu River where treated it. For this purpose, a wide range pharmaceutical classes influent (IWW) effluent samples taken from BBWWTP, Türkiye simultaneously identified quantified with liquid chromatography coupled tandem mass spectrometry following phase extraction sample preparation. A total 55 active groups 25 general drug (29 subgroups) were detected, highest average ratios being 82.459%, 7.306%, 4.949%, 2.145% analgesic-anti-inflammatory, antiepileptic, diabetic, antipyretic groups, respectively, IWW. Although flurbiprofen analgesic-anti-inflammatory 66.13% during 12-month period, had high risk quotient very initial concentration WWT 809.01–22,901.10 µg/L.

Bioelectroremediation of a Real Industrial Wastewater: The Role of Electroactive Biofilm and Planktonic Cells through Enzymatic Activities

Toxics, Год журнала: 2024, Номер 12(8), С. 614 - 614

Опубликована: Авг. 20, 2024

Bioelectrochemical processes are emerging as one of the most efficient and sustainable technologies for wastewater treatment. Their application industrial treatment is still low due to high toxicity difficulty biological effluents. This especially relevant in pharmaceutical industries, where different solvents, active pharma ingredients (APIs), extreme pH, salinity usually form a lethal cocktail bacterial community bioreactors. work evaluates impact anode architecture on detoxification performance analyzes, first time, profile some key bioremediation enzymes (catalase esterase) reactive oxygen species (ROS) during operation microbial electrochemical cells treating real wastewater. Our results show existence oxidative stress loss cell viability planktonic cells, while electrogenic bacteria that biofilm maintain their biochemical machinery intact, observed bioelectrochemical response. Monitorization electrical current flowing system showed how electroactive biofilm, after short adaptation period, started degrade effluent. The biofilms responsible this type
