This is the first study dealing with removal of pharmaceutical substances in municipal wastewater treatment plants (MWWTPs) from Peru and impact these compounds surface waters receiving treated wastewater. To this aim, samples MWWTP Lima (Peruvian Coast), Cusco, Puno Juliaca Highlands), as well water (confluence Torococha Coata rivers Juliaca) were analyzed. A total 38 target pharmaceuticals included determined by Liquid Chromatography coupled to tandem Mass Spectrometry (LC-MS/MS). Around 60% 75% could be quantified MWWTPs, respectively. Acetaminophen was drug found at highest concentration, it present all reaching average values above 100 μg/L department Puno. The gabapentin anti-epileptic (up 11.85 Lima) antibiotics clarithromycin, trimethoprim, ciprofloxacin, sulfamethoxazole azithromycin (1.86 4.47 also moderate concentrations In water, concentration corresponded acetaminophen (28.70 μg/L) followed (4.36 μg/L). As regards removal, data work showed that Cusco (aerobic biologic process synthetic trickling filters secondary treatment) more efficient than (a preliminary combines grilles, sand trap, degreaser-aerated sieved 1.0 mm). However, many (around 50% investigated) presented similar or even higher influent environmental ecological risk assessed based on calculated Risk Quotient (RQ) samples. According our data, three (clarithromycin, clindamycin) analgesic posed high (RQ ≥ 1) aquatic environment. river, (except norfloxacin) analgesic-anti-inflammatory acetaminophen, diclofenac a 1). Based reported for time Peru, can deduced processes applied important cities are not enough remove consequence, severe risks associated presence expected; so complementary should implemented MWWTPs elimination compounds.

The role of emerging organic contaminants in the development of antimicrobial resistance

Emerging contaminants, Journal Year: 2021, Volume and Issue: 7, P. 160 - 171

Published: Jan. 1, 2021

Antimicrobial resistance (AMR) threatens human and ecological health worldwide. Unless major changes occur across the human, animal environmental sectors, problem will continue to expand. An important component of AMR that deserves greater attention is influence emerging organic contaminants (EOCs) – ubiquitous compounds found, amongst others, in pharmaceuticals, personal care products, food, industrial agricultural plastics building materials. EOCs are widely used can accumulate environment from varied sources, predominantly via waste streams. interact with microbial communities potentially leading emergence spread AMR. Biocides pharmaceuticals have been demonstrated promote development. a multi-faceted requires input all robust strategies policies needed make headway solving issues this threat.

Activation of Peroxymonosulfate by Phosphate and Carbonate for the Abatement of Atrazine: Roles of Radical and Nonradical Species

ACS ES&T Water, Journal Year: 2022, Volume and Issue: 2(4), P. 635 - 643

Published: March 29, 2022

While the activation mechanisms of peroxymonosulfate (PMS) by various homogeneous and heterogeneous catalysts have been reported, chemistry PMS in a catalyst-free system its interactions with background oxyanions are still poorly understood. This paper demonstrated two prevalent (phosphate carbonate) revealed for enhanced atrazine (ATZ) degradation at neutral pH. Both activated to produce sulfate radical (SO4•–), which reacts ATZ rapidly, but phosphate exhibited stronger effect than carbonate. The reaction between SO4•– produced other possible radicals presence dissolved oxygen (e.g., ATZ–O–O•), subsequently generated singlet (1O2) superoxide (O2•–) as precursor. However, their contributions were minimal. formation species PMS–ATZ–phosphate was supported selective quenching electron paramagnetic resonance measurements under different conditions [oxic, anoxic, solvents (H2O D2O)]. Direct oxidation also observed. Overall, direct accounted 75–78% 22–25% degradation, respectively.
