Metformin Contamination in Global Waters: Biotic and Abiotic Transformation, Byproduct Generation and Toxicity, and Evaluation as a Pharmaceutical Indicator

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(19), P. 13528 - 13545

Metformin is the first-line antidiabetic drug and one of most prescribed medications worldwide. Because its ubiquitous occurrence in global waters demonstrated ecotoxicity, metformin, as with other pharmaceuticals, has become a concerning emerging contaminant. subject to transformation, producing numerous problematic transformation byproducts (TPs). The occurrence, removal, toxicity metformin have been continually reviewed; yet, comprehensive analysis pathways, byproduct generation, associated change adverse effects lacking. In this review, we provide critical overview fate during water treatments natural processes compile 32 organic TPs generated from biotic abiotic pathways. These occur aquatic systems worldwide along metformin. Enhanced several compared through organism tests necessitates development complete mineralization techniques for more attention on TP monitoring. We also assess potential indicate overall contamination pharmaceuticals environments, previously acknowledged ones, found be robust or comparable indicator such pharmaceutical contamination. addition, insightful avenues future research

Benchmarking tertiary water treatments for the removal of micropollutants and pathogens based on operational and sustainability criteria

Journal of Water Process Engineering, Journal Year: 2022, Volume and Issue: 46, P. 102587 - 102587

In a context of increasing water scarcity, it is essential to ensure an integrated watershed management, savings in the consumption as finite resource and improve performance wastewater treatment plants guarantee quality treated effluents. Therefore, advanced technologies for tertiary have been widely studied recent decades. These treatments reviewed over years mainly providing comparisons from technical perspective. However, there lack holistic evaluation considering environmental economic aspects together with aforementioned aspects. this review, alternatives micropollutant pathogen abatement identified based on implemented large scale (ozonation, ultraviolet treatment, adsorption activated carbon or membrane filtration) well those process implementation, such electrochemical, Fenton-based photocatalytic techniques. Thus, systematic bibliographic search was performed works applying pilot full-scale equipment, leaving lab-scale results out analysis. The description each allowed identification feasibility, operating costs associated impacts, comparative assessment that will help decision-making development application different technologies. benchmarking reveal selected should be chosen source specific pollutants present wastewater, no single solution micropollutants pathogens. addition, recommendations are presented publication reliable process-related data facilitate comparison between scenarios.
