Micropollutants monitoring in wastewater can serve as a picture of what is consuming society and how it impact the aquatic environment. In this work, suspect screening approach was used to detect known unknown contaminants samples collected from two treatment plants (WWTPs) located Basque Country (Crispijana Alava, Galindo Vizcaya) during weekly sampling campaigns, which included months April July 2020, part confinement period caused by COVID-19. To that aim, high-resolution mass spectrometry collect full-scan data-dependent tandem spectra water using database containing >40,000 chemical substances. The presence > 80 confirmed (level 1) quantified both WWTP samples, while at least 47 compounds were tentatively identified (2a). Among concern, an increase occurrence some for COVID-19 disease treatment, such lopinavir hydroxychloroquine, observed lockdown. A prioritization strategy environmental risk assessment carried out considering only effluents Crispijana WWTPs. scored based on removal efficiency, estimated persistency, bioconcentration factor, mobility, toxicity potential frequency detection samples. With approach, 33 (e.g. amantadine, clozapine or lopinavir) found be considered key analyzed their concentration, toxicity. Additionally, antimicrobial (RQ-AR) antiviral (EDRP) certain evaluated, where ciprofloxacin fluconazole represented medium antibiotic resistance (1 RQ-AR 0.1) ecosystems. Regarding mixture toxicity, computed sum toxic unit values different (> suggest interactions between need future assessments.

The SARS-CoV-2 pandemic had huge impacts on global urban populations, activity and health, yet little is known about attendant consequences for river ecosystems. We detected significant changes in occurrence risks from contaminants of emerging concern (CECs) waterways across Greater London (UK) during the pandemic. were able to rapidly identify monitor large numbers CECs n = 390 samples 2019-2021 using novel direct-injection liquid chromatography-mass spectrometry methods scalable targeted analysis, suspect screening prioritisation CEC risks. A total 10,029 measured environmental concentrations (MECs) obtained 66 unique CECs. Pharmaceutical MECs decreased lockdown 2020 R. Thames (p ≤ 0.001), but then increased significantly 2021 0.01). For tributary rivers, Lee, Beverley Brook, Wandle Hogsmill most impacted, primarily via wastewater treatment plant effluent combined sewer overflows. In particular, pharmaceutical MEC trends generally correlated with NHS prescription statistics, likely reflecting limited dilution. Suspect ∼ 1,200 compounds tentatively identified 25 additional at five impacted sites, including metabolites such as O-desmethylvenlafaxine, an EU Watch List compound. Lastly, risk quotients (RQs) ≥ 0.1 calculated 21 whole freshwater catchment, which seven medium (RQ 1.0) three high-risk category 10), imidacloprid 19.6), azithromycin (15.7) diclofenac (10.5).
