The increase of micro- and nano-plastics (MNPs) in aquatic environments has become a significant concern due to their potential toxicological effects on ecosystems, food web dynamics, human health. These plastic particles emerge from range sources, such as the breakdown larger waste, consumer products, industrial outputs. This review provides detailed report transmission dangers MNPs environmental behavior, interactions within webs, emphasizing toxic impact marine life. It explores relationship between particle size toxicity, distribution different tissues, process trophic transfer through web. MNPs, once consumed, can be found various organs, including digestive system, gills, liver. Their consumption by lower level organisms facilitates progression up chain, potentially leading bioaccumulation biomagnification, thereby posing substantial risks health, reproduction, behavior species. work also how persistence bioaccumulation, pose biodiversity disrupt relationships. addresses implications for particularly contaminated seafood, highlighting direct indirect pathways which humans are exposed these pollutants. Furthermore, highlights recommendations future research directions, integration ecological, toxicological, health studies inform risk assessments develop mitigation strategies address global challenge pollution environments.

Impact of Microplastics on Forest Soil Properties in Pollution Hotspots in Alluvial Plains of Large Rivers (Morava, Sava, and Danube) of Serbia

Forests, Journal Year: 2025, Volume and Issue: 16(2), P. 363 - 363

Published: Feb. 17, 2025

Plastic pollution has become a major environmental problem, while the products of its degradation, microplastics (MPs), appear everywhere on Earth. Data MPs in agricultural soils have appeared lately, but significant knowledge gap exists regarding forest soils. In Serbia, municipal waste is often dumped forests, creating problems that not been documented. To explore impact dumping and fluvisols, we evaluated from topsoils three dumps adequate visibly plastic non-contaminated sites located alluviums largest rivers Serbia. For assessing influence factors soil MPs, samples were taken vegetational seasons, two years. The structure, chemistry, microbial respiration (MR) was examined. Undisturbed columns uncontaminated with added known MP particles used to estimate dynamic transfer through topsoil. Large aggregate formation, coarse sand content, specific mass, porosity, available P, MR affected by contamination. Seasonal annual changes significantly influenced behavior luvisols. effectively penetrated deeper layers within 3 months, strong accumulation 0–10 cm layer.

Diffusion plays a crucial role in the mass transfer and migration of coalbed methane within coal-rocks. The diffusion coefficient is key parameter that influences CH4 porous media, including coal-rock. Conventional experimental approaches, reliant on theoretical solutions for determination, exhibit inherent limitations constraints, protracted procedures, susceptibility to errors. Addressing these shortcomings, this study introduces numerical method based inverse problem calculation, core lies an optimization process adjusts model parameters by minimizing error between observed data predictions, ensuring output closely matches actual values. Building traditional isothermal adsorption experiment CH4, we use pressure fluctuation as penalty factor, techniques are employed determine coal particle coefficient. results indicate during initial stage, molecules rapidly penetrate into particles, followed process. flow sequence over different time periods adheres sequential transport mode “free flow, permeation, diffusion, adsorption.” Using model, determined particles be 1.295 × 10−13 m2/s through reverse optimization. fitting accuracy (R2) with was 0.973, which indicates reliability results.
