TL;DR: In this review, the key advancement on the preparation and modification of novel adsorbents and their adsorption capacities for dyes removal under various conditions have been highlighted and discussed.

TL;DR: The sorption kinetics and isotherms models indicated that the sorption capacity of aged microplastic is higher than that of pristine microplastics, and their physical interactions, including partitioning, electrostatic interactions, and intermolecular hydrogen bonding, were the dominant mechanism.

TL;DR: It is identified that microplastic used in experiments are often different to those quantified in the marine environment, particularly in terms of concentration, shape, type and age, and it is suggested that future research should include microplastics that are more representative of those found in the Marine environment at relevant concentrations.

TL;DR: The preparation and modification of novel-nanomaterials (e.g., MOFs, nZVI, MXenes, and g-C3N4), the heavy metal ions' sorption properties, and the impact of environmental conditions have been discussed.

TL;DR: The results showed that the biomass and catalase (CAT) enzymes activity of V. faba roots decreased under 5 μm PS-MPs whereas superoxide dismutase (SOD) and peroxidase (POD) enzyme activity significantly increased, and under the 100 nm PS- MPs exposure a significant decrease of growth was observed only at the highest concentration.

TL;DR: Recent progresses in understanding metal-biochar interactions in soils, potential risks associated with biochar amendment, and application of biochar in soil remediation in China indicate that the remediation effect depends on the characteristics of both biochar and soil and their interactions.

TL;DR: In this article, the authors used various microscopic techniques (fluorescence, polarized light, SEM) to quantify and classify microplastics (MPs) and microrubbers (MRs) in urban and industrial environments that are potentially ingestible or inhalable by humans.

TL;DR: The results reveal that whilst marine microplastics have received substantial scientific research, the extent of microplastic pollution in continental environments, such as rivers, lakes, soil and air, and environmental interactions, remains poorly understood.

TL;DR: It is proposed the use of mussels as target species to monitor microplastics and call for a uniform, efficient and economical approach that is suitable for a future large-scale monitoring program.

TL;DR: Results indicated that microplastics in soil, compared with those in aquatic environments, can also act as a distinct microbial habitat, potentially altering the ecological functions of soil ecosystems.

TL;DR: There are still knowledge gaps in the determination and quantification of nanoplastics, as well as their contaminant release mechanisms, degradation rates and process from large plastics to nanoplastic, and the transportation of nanopLastics along food chains.

TL;DR: A number of countermeasures to address soil Cd contamination are proposed, including i) mitigation of Cd transfer from paddy soils to rice grain, and ii) intervention in those farmers who consume home-grown Cd-contaminated rice.

TL;DR: This paper aims to summarize recent research results on the excellent removal ability of GO-based nanomaterials for various heavy metal ions in aqueous solutions and provide some thrilling information for the design and manufacture of GOs for the elimination of heavyMetal ions from wastewater in environmental pollution management.

TL;DR: An investigation of the adsorption of Cd, Co, Cr, Cu, Ni, Pb and Zn by five different types of microplastics was performed in Milli-Q water and natural waters, showing an enhancement of metal Adsorption in waters with high chemical and biological oxygen demands as urban wastewater and irrigation water.

TL;DR: It is demonstrated that rivers in the Tibet Plateau have been contaminated by microplastics, not only in developed areas with intense human activity but also in remote areas, where microplastic pollution requires further attention.

TL;DR: It is demonstrated that microplastic pollution in river environments has progressed more in polluted rivers with poor water quality than in rivers with good water quality, leading to the conclusion that the sources and inflow processes of microplastics inRiver environments are similar to those of other pollutants.

TL;DR: A higher partitioning to MPs of chemical contaminants in soil is expected in comparison to aquatic environments as well as the effects of combined exposure to chemicals and MPs on the toxicity and bioaccumulation in biota are discussed.

TL;DR: The results suggest that MFs have adverse impacts on the fitness of soil organisms, and highlight the ecological risks of microplastic pollution in terrestrial ecosystems.

TL;DR: It is suggested that microplastic pollution is widespread in commercial bivalves and a systematic and integrative market-basket survey is recommended to clarify the current status of human exposure to microplastics.

TL;DR: The results suggest that both the abundance and properties of microplastic pollution varies across different water bodies, and support prioritization of water monitoring for microplastics within entire river networks, instead of single water body surveys.

TL;DR: It is demonstrated for the first time that environmentally relevant concentrations of microplastics had adverse effects on the reproduction of marine medaka and might pose a potential threat to marine fish populations.

TL;DR: The results showed that a 5% concentration of MPs had no significant effect on soil DOC, whereas the formation of aromatic functional groups was accelerated, and smaller MPs increased the community richness and diversity of both bacterial and fungal communities in fertilized soil.

TL;DR: The results indicated that biochar could act as both electron donor and electron shuttle for the reduction of Cr( VI) during the sorption process, making it an alternative for removal of toxic Cr(VI) from wastewaters.

TL;DR: Insight is provided in establishing reuse and resource recovery as the holistic approach towards sustainable AMD treatment and integrated technologies that deserve in depth future exploration are highlighted.

TL;DR: It is suggested that soils may not only represent a sink for MPs, but also a feasible entryway to subsurface receptors, such as subterranean fauna or aquifers.

TL;DR: Black carbon and organic carbon are important detrimental components of PM2.5, while other constituents are probably hazardous to human health, however, more studies are needed to further confirm the results.

TL;DR: Findings of this study suggested that under environmentally relevant conditions, microplastics should not cause significant toxic effects to E. fetida, nor enhance its accumulation of hydrophobic contaminants.

TL;DR: The present research provides evidences that the existence of organic pollutants is capable of influencing the effects ofmicroplastics, and the further research on the joint toxicity of microplastics with different pollutants is urgent.

TL;DR: Findings show that MPs with different particle sizes have vary adsorption behaviors and load capacities for environmental pollutants, which deserve further concerned.

TL;DR: The occurrence of microplastic on Forni Glacier may be due to the gathering of debris coming from the large accumulation area into the relatively smaller ablation area of the glacier, as a consequence of its flow and melting.
