Microplastics pose a serious ecological threat to agricultural soils, as they are very persistent in nature. can enter the soil system different ways and present shapes concentrations. However, little is known about how plants react microplastics with concentrations shapes. To this end, we conducted factorial pot experiment wheat (Triticum aestivum L.) which mixed polystyrene (PS) (bead, fiber powder) at of 0, 1, 3 5%. Although all PS significantly reduced morphological growth traits, powder shape was microplastic that plant height (by 58–60%), fresh biomass 54–55%) dry 61–62%) most, especially 3% 5% compared 0% PS. Similar negative effects were also observed for root length weight concentrations, regardless shape. A concentration-dependent reduction leaf area index (LAI) observed. Interestingly, increasing concentration tended up-regulate activity antioxidant enzymes shapes, indicating potential complexity highly time-dependent response related various reactive oxygen species (ROS). Importantly, caused significant chlorophyll pigmentation photosynthetic rate. For transpiration rate, stomatal conductance intercellular CO2 concentration, on increased increase Overall, concluded higher potentially more devastating physiological biochemical attributes wheat, evidenced by pigments gas exchange parameters We recommend further research experiments not only translocation but tissue-specific retention sizes crops fully understand their impact food safety.

Computational polarized holography for automatic monitoring of microplastics in scattering aquatic environments

APL Photonics, Journal Year: 2025, Volume and Issue: 10(3)

Published: March 1, 2025

Automatic monitoring of microplastic (MP) contamination in aquatic ecosystems is crucial for effective management and mitigation strategies. However, this task presents significant challenges due to the dynamic 3D distribution MPs light scattering aqueous phase. Traditional MP detection methods are limited volumetric imaging anti-scattering capability, often requiring cumbersome manual processing analysis. In study, we develop an integrated system based on computational polarized holography, which offers unique advantages automation, multifunctionality, affordability. As demonstrated with proof-of-concept experiments, our enables accurate efficient tracking across extended volume, facilitating high-throughput addition, proposed hybrid de-scattering algorithm substantially improves image quality even when characterizing milk solutions. Furthermore, unsupervised clustering method developed identify classify different their multimodal features without need annotation. Although experiments were implemented laboratory, results demonstrate robust efficiency material-dependent sensitivity system. It opens up new opportunities on-site continuous pollution ecosystems, contributing significantly sustainable environmental management.

Abstract Microplastic fibers (MPF) are the largest fraction of microplastics in environment by mass. The endpoints these contaminants' movement is generally known at large‐scale (i.e., their origins and where they end up), but mechanics how get to those sinks remains poorly understood. objective this work was improve understanding mechanisms driving MPF migration through terrestrial systems directly imaging motion idealized representations porous media. Monofilament line with 0.3 mm diameter passed a bench‐scale, pseudo‐2d flow cell capture trajectories MPFs three different lengths passive micro‐bead tracers were also captured. Video processing automated image analysis converted video experiments into database trajectories, allowing comparison experimental data various numerical models. Simple advection‐dispersion models adequate for modeling tracer did not provide good description transport. A physics‐based, distributed model able generate realistic domain, speeds initial simulation too fast, despite working well tracer. Adding delay (waiting time) process resulted travel times. specifics could be deduced from experiments, its overall impact on transport provides mechanistic insights. These direct observation moving media show that likely have strong interactions surroundings.
