Effective management of water resources is crucial for global food security and sustainable development. In this Review, we explore the potential benefits challenges associated with treated wastewater (TW) reuse irrigation. Currently, 400 km3 yr−1 generated globally, but <20% treated, that TW, only 2–15% reused irrigation depending on region. The main limitation TW inability current treatment technologies to completely remove all micropollutants contaminants emerging concern, some which have unknown impacts crops, environment health.

Scarcity of freshwater for agriculture has led to increased utilization treated wastewater (TWW), establishing it as a significant and reliable source irrigation water. However, years research indicate that if not managed adequately, TWW may deleteriously affect soil functioning plant productivity, pose hazard human environmental health. This review leverages the experience researchers, stakeholders, policymakers from Israel, United-States, Europe present holistic, multidisciplinary perspective on maximizing benefits municipal use irrigation. We specifically draw extensive knowledge gained in world leader agricultural implementation. The first two sections work set foundation understanding current challenges involved with TWW, detailing known emerging agronomic issues (such salinity phytotoxicity) public health risks contaminants concern pathogens). then presents solutions address these challenges, including technological management-based well control policies. concluding section suggestions path forward, emphasizing importance improving links between policy, better outreach practitioners. this platform call action, form global harmonized data system will centralize scientific findings agronomic, effects Insights such collaboration help mitigate risks, facilitate more sustainable food production future.

Exploration of novel solid-phase extraction modes for analysis of multiclass emerging contaminants

Analytica Chimica Acta, Journal Year: 2024, Volume and Issue: 1319, P. 342955 - 342955

Published: July 9, 2024

Solid-phase extraction (SPE) has gained an essential role in environmental analytical chemistry. Classic off-line SPE coupled with LC-MS/MS systems creates powerful procedures for ultratrace analysis of contaminants emerging concern (CECs) water. But, being associated tedious work and large consumption materials, alternative modes are becoming interesting. As so, the study focuses on development, evaluation, overall comparison established novel modes. Off-line SPE, dispersive micro (DMSPE), 'fast' single-pump on-line were explored, using commercially available sorbents. Their efficiency was evaluated their performance water 20 multiclass CECs.

Presence of Micropollutants and Transformation Products During Subsurface Irrigation with Treated Wastewater Assessed by Non-Target Screening Analysis

ACS ES&T Water, Journal Year: 2025, Volume and Issue: 5(2), P. 891 - 901

Published: Jan. 15, 2025

While wastewater treatment plant (WWTP) effluent offers a potential alternative source for irrigation, the fate of organic micropollutants (OMPs), including transformation products (TPs), in effluent-irrigated fields remains largely unknown. Using non-target analysis (NTA), we investigated OMPs WWTP and their distribution throughout full-scale subsurface irrigation (SSI) field where was used irrigation. Our results indicate that TPs accounted approximately 80% detected OMPs. Weather SSI hydrology seem to influence OMP transformation. Wetter conditions promoted deeper leaching soil, drier favored capillary rise biotransformation, as shown by detection 37% more rhizons during dry year. On average 45 OMPs, at least 50% with logD <3, were −2.3 m depth, highlighting reach groundwater importance further risk assessment. This approach demonstrates how NTA subsequent data tools can support identification (unknown) contribute understanding under conditions, which is first step an exposure-driven environmental Overall, our study emphasizes carefully considering responsible reuse.

Multiclass screening methods involving hundreds of structurally unrelated compounds are becoming essential in many control labs and research areas. Accurate mass a theoretically unlimited number chemicals can be undertaken using liquid chromatography coupled to high resolution spectrometry (LCHRMS), but the lack comprehensive sample treatments hinders this potential. In research, capability supramolecular solvents (SUPRAS) for making liquid-liquid microextraction (LLME) multiclass based on LCHRMS was firstly explored. For purpose, SUPRAS made up 1,2-hexanediol, sodium sulphate water synthesized directly urine applied compound extraction interference removal eighty prohibited substances sports by LC-electrospray ionization-time flight spectrometry. Selected included wide range polarities (log P from -2.4 9.2) functionalities (e.g. alcohol, amine, amide, carboxyl, ether, ester, ketone, sulfonyl, etc.). No interfering peaks were observed any 80 investigated. Around 84-93% drugs efficiently extracted (recoveries 70-120%) 83-94% analytes did not show matrix effects (±20%) ten tested urines. Method detection limits interval 0.002-12.9 ng mL-1, which accordance with Minimum Required Performance Levels values established World Anti-Doping Agency. The applicability method evaluated thirty-six blinded anonymized samples, previously analyzed gas or chromatography-triple quadrupole. Seven samples lead an adverse analytical finding line results obtained conventional methods. This proves that LLME constitutes efficient, economic, simple treatment methods, application is unaffordable organic solvents.
