Abstract Microplastic (MP) pollution has emerged as a global environmental concern due to its ubiquity and harmful impacts on ecosystems human health. MP assessment therefore become increasingly necessary common in experimental samples. Microscopy spectroscopy are widely employed for the physical chemical characterization of MPs. However, these analytical methods often require time-consuming pretreatments samples or expensive instrumentation. In this work, we develop portable cost-effective polarization holographic imaging system that prominently incorporates deep learning techniques, enabling efficient, high-throughput detection dynamic analysis MPs aqueous environments. The integration enhances identification classification MPs, eliminating need extensive sample preparation. simultaneously captures interference patterns states, allowing multimodal information acquisition facilitate rapid detection. characteristics light waves registered, birefringence features leveraged classify material composition structures Furthermore, automates real-time counting morphological measurements various materials, including sheets additional natural substances. This innovative approach significantly improves monitoring provides valuable their effective filtration management.

Abstract As an emerging pollutant in the life cycle of plastic products, micro/nanoplastics (M/NPs) are increasingly being released into natural environment. Substantial concerns have been raised regarding environmental and health impacts M/NPs. Although diverse M/NPs detected environment, most them display two similar features, i.e.,high surface area strong binding affinity, which enable extensive interactions between surrounding substances. This results formation coronas, including eco-coronas bio-coronas, on different media. In real exposure scenarios, corona is inevitable often displays variable complex structures. The coronas found to impact transportation, uptake, distribution, biotransformation toxicity particulates. Different from conventional toxins, packages rather than bare particles more dangerous. We, therefore, recommend seriously consideration role safety assessments. review summarizes recent progress eco–coronas bio-coronas M/NPs, further discusses analytical methods interpret structures, highlights provides future perspectives.

Nano/microplastic (NP/MP) pollution is a growing concern for the water environment. Wastewater treatment plants (WWTPs) are considered major recipients of MP before discharging into local waterbodies. MPs enter WWTPs mainly from synthetic fibers through washing activities and personal care products. To control prevent NP/MP pollution, it essential to have comprehensive understanding their characteristics, fragmentation mechanisms, effectiveness current processes used in removal. Therefore, objectives this study (i) understand detailed mapping WWTP, (ii) mechanisms NP, (iii) investigate removal efficiency by existing WWTP. This found that fiber dominant shape MP, polyethylene, polypropylene, polyethylene terephthalate, polystyrene polymer type wastewater samples. Crack propagation mechanical breakdown due shear forces induced facilities (e.g., pumping, mixing, bubbling) could be causes NP generation Conventional ineffective complete MPs. Although these capable removing ∼95% MPs, they tend accumulate sludge. Thus, significant number may still released environment on daily basis. suggested using DAF process primary unit can an effective strategy initial stage goes secondary tertiary stage.

The production and disposal of plastics have become significant concerns for the sustainability planet. During past 75 years, around 80% plastic waste has either ended up in landfills or been released into environment. Plastic debris environment breaks down smaller particles through fragmentation, weathering, other disintegration processes, generating microplastics (plastic ≤ 5 mm size). Although marine aquatic ecosystems primary focus microplastic pollution research, a growing body evidence suggests that terrestrial are equally at risk. Microplastic contamination reported various environments from several sources such as mulch, pharmaceuticals cosmetics, tire abrasions (tire wear particles), textiles industries (microfibers), sewage sludge, dumping. Recent studies suggest soil sink pollutants is often contaminated with mixture organic inorganic pollutants. This gradually caused adverse impacts on health fertility by affecting pH, porosity, water-holding capacity, microbial enzymatic activities. Microplastics can interact co-existing adsorbing contaminants onto their surfaces intermolecular forces, including electrostatic, hydrophobic, non-covalent, partition effects, van der Waals microporous filling mechanisms. subsequently delays degradation process existing contaminants, thereby ecological activities ecosystem. Thus, present article aims to elucidate deleterious impact interactions review also addresses disrupting

The analysis of microplastics (MPs) in terrestrial environments and the evaluation their environmental risk has gained great attention, owing to increasing evidence for widespread presence soils freshwater sediments globally. Once environment, MPs undergo abiotic biotic processes which alter properties integrity: this process is called "aging" implications fate these contaminants, morphology surface chemistry. Aging may also affect analytical assessment samples: samples likely contain aged MPs, while methods are generally established using pristine plastics validation. This can lead uncertainties quantification characterization. critical review summarizes current trends simulation characterization MP aging laboratory conditions, highlighting limitations knowledge gaps. It discusses challenges induced by samples, providing directions toward possible solutions.

BackgroundMicroplastic (MP) pollution has emerged as a significant environmental concern worldwide. While extensive research focused on their presence in marine organisms and ecosystems, potential impact human health, particularly the circulatory system, remains understudied. This project aimed to identify quantify mass concentrations, polymer types, physical properties of MPs thrombi surgically retrieved from both arterial venous systems at three anatomically distinct sites, namely, cerebral arteries brain, coronary heart, deep veins lower extremities. Furthermore, this study investigate association between levels disease severity.MethodsThrombus samples were collected 30 patients who underwent thrombectomy procedures due ischaemic stroke (IS), myocardial infarction (MI), or vein thrombosis (DVT). Pyrolysis–gas chromatography spectrometry (Py-GC/MS) was employed concentrations MPs. Laser direct infrared (LDIR) spectroscopy scanning electron microscopy (SEM) used analyse Demographic clinical information also examined. A rigorous quality control system eliminate contamination.FindingsMPs detected by Py-GC/MS 80% (24/30) obtained with IS, MI, DVT, median 61.75 μg/g, 141.80 69.62 respectively. Among 10 target types MP polymers, polyamide 66 (PA66), polyvinyl chloride (PVC), polyethylene (PE) identified. Further analyses suggested that higher may be associated greater severity (adjusted β = 7.72, 95% CI: 2.01–13.43, p < 0.05). The level D-dimer MP-detected group significantly than MP-undetected (8.3 ± 1.5 μg/L vs 6.6 0.5 μg/L, 0.001). Additionally, LDIR analysis showed PE dominant among 15 identified MPs, accounting for 53.6% all mean diameter 35.6 μm. shapes polymers using SEM found heterogeneous.InterpretationThis presents qualitative quantitative evidence thrombotic diseases through use multimodal detection methods. Higher increased severity. Future larger sample size is urgently needed sources exposure validate observed trends study.FundingThis funded SUMC Scientific Research Initiation Grant (SRIG, No. 009-510858038), Postdoctoral (No. 202205230031-3), 2020 Li Ka Shing Foundation Cross-Disciplinary 2020LKSFG02C).
