The extensive use of plastic products by people has led to the prevalence microplastics (MPs) in aquatic and terrestrial ecosystems. MPs will be able undergo multiple aging processes release dissolved organic matter (DOM) environment, thereby further affecting ecosystem. Therefore, this thesis systematically investigated photo-aging properties polyvinyl chloride (PVC), characterized changes physicochemical properties; addition, DOM composition fluorescence characteristics leachate were using TOC 3D-EEMs. Our results showed that O/C ratio can quantitatively characterize surface MPs. Furthermore, We chose Malachite green (MG) Sulfamethoxazole (SMX), which are abundantly present aqueous as target pollutants, through adsorption experiments we established regression equations equilibrium capacity with or CI mean particle size. Exploring relationship between help predict degree accumulation hydrophilic contaminants natural environment.

The production and consumption of disposable face masks (DFMs) increased intensely during the COVID-19 pandemic, leading to a high amount them being found in terrestrial aquatic environment. main goal this research study is conduct comparative evaluation water-leachability microplastics (MPs) chemical additives from various types surgical/medical (MM DFMs) filtering pieces (FFPs). Fourier-Transform Infrared Spectroscopy was used for MPs analysis. Liquid Chromatography/High Resolution Mass Spectrometry analyse analytes presented water-leachates DFMs. FFPs released 3-4 times more microplastic particles compared MM release into water all tested DFMs without mechanical stress suggests potential MP contamination originating DFM process. Our first time identified bisphenol B (0.25-0.42 μg/L) 1,4-bis(2-ethylhexyl) sulfosuccinate (163.9-115.0 as leachables vary size, with predominant <100 μm, order MMIIR > MMII FFP3>FFP2>MMI. type leachates investigated polypropylene, accounting 93-97% 82-83% FFPs. Other polymers such polyethylene, polycarbonate, polyester/polyethylene terephthalate, polyamide/Nylon, polyvinylchloride, ethylene-propylene copolymer were also identified, but smaller amounts. wider variety higher percentage (17-18%) other (3-7%). Fragments fibres water-leachate samples, fragments, particularly debris polypropylene fibres, most common morphotype. findings are important contributing additional data develop science-based policy recommendations on health environmental impacts associated originated

Rhamnolipid: Nature-based solution for the removal of microplastics from the aquatic environment

Integrated Environmental Assessment and Management, Год журнала: 2025, Номер unknown

Опубликована: Янв. 6, 2025

Abstract Over the past two decades, research into accumulation of small plastic particles and fibers in organisms environmental settings has yielded over 7,000 studies, highlighting widespread presence microplastics ecosystems, wildlife, human bodies. In recent years, these contaminants have posed a significant threat to human, animal, health, with most efforts concentrated on removing them from aquatic systems. Given this urgency, purpose study was investigate potential rhamnolipid, biosurfactant, for removal water. Specifically, evaluates effects water matrix, initial pH solution (7.0, 7.5, 8.0, 8.5, 9.0, 9.5, 10.0), concentrations alum (5, 10, 20, 30, 40, 50 mg/L), rhamnolipid (1, 5, 80, 100 mg/L). Optimum achieved at 5.0 mg/L 1.0 mg/L, respectively, 8.0. both types tested, efficiency about 74% determined, indicating as nature-based control microplastic pollution surface waters.
