The fate of ubiquitous microplastics (MPs) is largely influenced by dissolved organic matter (DOM) in aquatic environments, which has garnered significant attention. reactivity DOM reported to be greatly regulated molecular weights (MWs), yet little known about the effects different MW on MP aging. Here, aging behavior polystyrene MPs (PSMPs) presence fulvic acids (FAs) and humic (HAs) was systematically investigated. Under ultraviolet (UV) illumination, O/C PSMPs aged for 96 h surged from 0.008 0.146 lower FA (FA<1kDa) treatment, suggesting PSMP However, exhibited a stronger effect facilitating photoaging than HA, can attributed fact that FA<1kDa contains more quinone phenolic moieties, demonstrating higher redox capacity. Meanwhile, compared other fractions, actively involved increase reactive species yields 50–290%, including •OH, plays key role photoaging, contributed 25% electron-donating capacity (EDC). This study lays theoretical foundation better understanding environmental MPs.

With the widespread use of plastic products, microplastic (MP) pollution has become an important factor threatening water environment and human health. Ultrafiltration (UF) technology, based on organic polymer membranes, is a common method to remove MPs in treatment processes, offering high removal efficiency scalability. However, plants (WTPs), oxidation pretreatment often applied before UF, presence oxidants can affect membrane performance. In this study, we constructed polyvinylidene fluoride (PVDF) ultrafiltration for gravity filtration system investigate impact sodium hypochlorite polystyrene (PS) under filtration. As result, pre-chlorination reduced PS deposition membranes by improving flux stability (15.1%) but significantly decreased rate (from 36.6% 22.6%). Pre-oxidation facilitated shift fouling behavior toward intermediate blocking while reducing standard enhancing irreversible recovery. continuous chlorine exposure increased porosity pore size, substituted fluorine with chlorine, led carbon leaching, indicating pre-oxidation jeopardizes separation These findings provide insights into development novel strategies aimed at sustainability processes WTPs.

Microplastic, which is of size less than 5 mm, gaining a lot attention as it has become new arising contaminant because its ecophysiology impact on the aquatic environment. These microplastics are found in freshwater or drinking water and major carriers pollutants. Removal this microplastic can be done through primary treatment process, secondary tertiary process. One approach for remediation ultrafiltration technology, involves passing membrane with small pores to filter out microplastics. However, efficiency technology affected by structure type present water. New strategies created improve increase efficacy removing from knowing how various types shapes react during ultrafiltration. The filter-based technique, that is, achieved best performance removal microplastic. But ultrafiltration, too some sizes passes enters food chain. Accumulation also leads fouling. Through review article, we have assessed structure, size, MPs remediation, these factors affect filtration process challenges occur filtration.

Microplastics (MPs), defined as plastic particles smaller than 5 mm, are increasingly recognized environmental contaminants with potential health risks. These emerge breakdown products of larger plastics and omnipresent in marine, freshwater, terrestrial ecosystems. They primarily composed polymers such polyethylene, polypropylene, polystyrene, additives that enhance their performance. MPs also adsorb harmful chemicals like persistent organic pollutants heavy metals, posing risks to human health. Human exposure occurs mainly through ingestion inhalation, detected food products, water, even the air. have been shown accumulate gastrointestinal tract, disrupting gut microbiome, causing dysbiosis-a imbalance between beneficial bacteria. This disruption has linked various issues, including disorders, systemic inflammation, chronic diseases. Furthermore, gut-brain axis may be affected, neuroinflammatory consequences. As research continues unravel impacts MP exposure, understanding mechanisms accumulation broader implications on is crucial. review highlights effects health, emphasizing impact microbiome. We discuss connections cardiometabolic inflammatory diseases, disorders related Gut-Brain Axis.
