Abstract This review explores the hidden hazards associated with reuse of treated wastewater and sewage sludge in agriculture while proposing mitigation strategies. It examines origins pathways microplastics (MPs) treatment plants how these pollutants infiltrate agricultural ecosystems. The assesses effectiveness MP removal from its fate soil after reuse, highlighting contamination dynamics need for proactive measures. Introducing remediation methods is crucial addressing this issue. Alarming evidence MPs human blood, testis, semen, placenta underscores urgency solutions, revealing significant threats to health, particularly reproductive health. advocates sustainable practices effective strategies mitigate contamination, promoting environmental preservation, food safety, health protection.

Microplastics (MPs) increase global awareness due to their ubiquity, high concentration levels, and devastating effects on the aquatic environment. Wastewater treatment plants (WWTPs) are recognized as a significant source of microplastics in terrestrial environments, particularly for plastics used personal care products textile fibers from clothing industry. The focus present study was determination MP wastewater sewage sludge samples WWTP Ioannina city, according shape, size, concentration, polymer type. A wet peroxide oxidation (WPO) method using 30% H2O2 0.05 M ferrous (II) solution applied water effluent, while an enzymatic digestion combined with WPO employed eliminate organic matter extract MPs samples. Micro-Raman spectroscopy coupled appropriate software detect quantify microplastic particles. outcomes this showed that most representative shape effluent fragments (66.7% 75%, respectively), followed by fibers, spheres, films. Polyamide (PA), p -acrylic acid (PAA), -acrylamide-co-p (PAM-co-PAA) were abundant polymers (100% frequency detection), -vinyl chloride (PVC), -butyl methacrylate (PBMA), -ethylene (PE), -styrene (PS), -propylene (PP), alcohol (PVA), butyral (PVB) (20%-80% detection). mean five sampling campaigns 5.8 ± 0.6 particles/L secondary effluents 33.3 8 particles/g sludge. This focused monitoring campaign, order better understand occurrence, impact, risks associated WWTPs.

Microplastics are pollutants formed from fragmented plastics and also industrially manufactured for personal care cosmetic products. They range 1 µm to 5 mm ubiquitous in the environment due their tiny size, lightweight, wide applications. Ecotoxicological studies have shown that they can induce multiple harmful effects on exposed organisms humans. Wastewater treatment plants (WWTPs) drawn interest of researchers regulatory bodies worldwide as a point source microplastics discharge environment. In absence standardized methodology, microplastic monitoring WWTPs has been marked by distinct variations sample processing analytical procedures which limit comparison results. This review provides detailed analysis methods patterns, analytical, size characterization, quantification WWTPs. According procedural steps extraction reported reviewed studies, 12 patterns three categories approaches (single, dual, multiple) were identified. quantified using gravimetry method, mass sub-sample method (based extrapolation) with latter being most applied technique. Microplastic characterization accomplished two main methods: sieve-based technique computing-based

Transport and Deposition of Microplastics at the Water–Sediment Interface: A Case Study of the White River near Muncie, Indiana

Hydrology, Год журнала: 2024, Номер 11(9), С. 141 - 141

Опубликована: Сен. 6, 2024

Microplastics, plastic particles smaller than 5 mm, pose a significant environmental threat due to their persistence and distribution in aquatic ecosystems. Research on the dynamics of microplastics within freshwater systems, particularly concerning transport deposition along river corridors, remains insufficient. This study investigated occurrence at water–sediment interface White River near Muncie, Indiana. Sediment samples were collected from three sites: Woods (upstream), Westside Park (midstream), Morrow’s Meadow (downstream). The microplastic concentrations varied significantly, with highest concentration recorded upstream, indicating strong influence agricultural runoff. types identified predominantly fragments (43.1%), fibers (29.6%), films (27.3%), being consistently most abundant all sampling sites. A polymer analysis selected using Fourier-transform infrared (FTIR) spectroscopy revealed that common polymers polyethylene (PE), polypropylene (PP), terephthalate (PET). hydrodynamic conditions played crucial role microplastics. statistical demonstrated positive correlation between flow velocity downstream site, suggesting lower velocities contribute accumulation finer sediments Conversely, upstream midstream sites exhibited weaker correlations, other anthropogenic factors, such as land use sediment texture, may retention transport. provides valuable insights into complex interactions dynamics, characteristics, systems. These findings growing body knowledge pollution can help guide mitigation strategies aimed reducing contamination riverine
