TL;DR: This manuscript aims to reach a consensus on a definition for microplastics which can be useful for research, reporting and legislative purposes and considers physical and chemical defining properties.

TL;DR: It is demonstrated that all ecosystem services are impacted to some extent by the presence of marine plastic, with a reduction in provision predicted for all except one, which is evidenced to have implications for human health and wellbeing.

TL;DR: This review mainly summarized the interactions of organic pollutants and metals with microplastics based on environmental monitoring results and laboratory results reported by literatures.

TL;DR: It is argued that a large fraction of plastic waste accumulates here, as only thick-walled, larger plastic debris from low-density polymers are transported through currents from rivers to ocean, while the larger fraction is likely retained in sediments or beaches.

TL;DR: This study investigated the removal of microplastics from different treatment stages in three WWTPs and examined the performance of tertiary treatment that was done by coagulation and different technologies such as ozone, membrane disc-filter, and rapid sand filtration.

TL;DR: SEM images show microplastic surfaces with characteristic cracks, suggests their polymer aging, mechanical and oxidative weathering, which was found highest for the microplastics collected from Mumbai.

TL;DR: It is demonstrated that polyvinyl chloride, polypropylene, polyethylene, polyamides and polyformaldehyde could adsorb lead, copper and cadmium in the simulating solution, and the heavy metals showed higher adsorbance on PVC and PP particles compared with PA, PE and POM.

TL;DR: This article focuses on global microfiber generation and its sources, pathway of its entry into the environment and food chain, potential threat to aquatic animals and humans, present treatment technologies, and future challenges.

TL;DR: Using well-controlled aquatic biodegradation experiments it was shown that cotton and rayon microfibers are expected to degrade in natural aquatic aerobic environments whereas polyester microf fibers areexpected to persist in the environment for long periods of time.

TL;DR: The present note addresses the role of microplastics as vectors of contaminants in water bodies, stressing the need for future investigations on this hot topic.

TL;DR: The idea that blue mussels are a promising sentinel species for MPs (<200 μm) is supported, suggesting its importance as a MPs entry route into the marine coastal environment.

TL;DR: How chronically exposed species may suffer from microplastics-induced gut dysbiosis, deteriorating host health, and corresponding future directions of research are summarized.

TL;DR: The load of microplastics in the Western Mediterranean Sea is determined and microplastic aggregation potential was determined by inspecting formed biogenic aggregates either during sample collection or in the laboratory, indicating longer exposure times in the environment.

TL;DR: KOH is recommended as the most viable extraction method for exposure risk studies, due to microplastics recovery from bivalve tissues of single-digit micrometre size.

TL;DR: The results indicated that the mixed order (MO) model provided good prediction for the kinetics data and the linear isotherm represented adequately the sorption equilibrium data in freshwater.

TL;DR: The recreation, religious and fishing activities are the major contributors to plastic pollution in these beaches, which is borne out by the high abundance of MPs in the study sites, which requires a regular and permanent waste management system for the protection of beaches.

TL;DR: The highest number of ingested microplastics was measured in Eleutheronema tridactylum and Clarias gariepinus, suggesting their potential as indicator species to monitor and study trends of ingested marine litter.

TL;DR: Preliminary results represent a baseline for the implementation of the Marine Strategy Framework Directive descriptor 10 in Italy as well as an important step for detecting microplastics in bioindicator species from different GSAs.

TL;DR: There is a pressing-need to investigate the distribution of microplastics in sediments and biota of this Bay as well as their effects on marine life and human health, according to current study.

TL;DR: For the first time, pollution by marine litter and microplastics were evaluated in mangrove soils of the Ciénaga Grande de Santa Marta, where 540 ± 137 and 31‽±‽23 items/ha of marine litter were determined inMangroves near and away from populated centers respectively.

TL;DR: It is suggested that MP pollution was widespread and exhibited a relatively high level in commercial molluscs collected from Bizerte lagoon, suggesting trophic transfer in the food web and human exposure risks by diet.

TL;DR: The first estimates of floating macro-litter in surface waters from the Rhone River are presented, based on monthly visual observations during 1-year period (2016-2017), confirming its predominance in riverine floating litter.

TL;DR: The role of microplastics as vectors for organisms should be further evaluated in the future research and could accelerate the diffusion of organisms in the environment, which may result in biological invasion and increase the gene exchange between attached biofilm communities.

TL;DR: There is a pressing need to include microplastics in the ballast water management convention as a hazardous material and efficient on-board water treatment strategies and effective limits for microplastic in ballast waters need to be developed.

TL;DR: S sulfamethazine sorption onto microplastics decreased when pH and salinity increased and the main mechanisms involved in sorption are electrostatic and Van der Waals interaction.

TL;DR: This study is the first to report concentration ranges of identified plastic particles from a Norwegian fjord, down to sizes below the limit of visual identification, which provides a baseline for future comparison, and point at relevant sizes for environmental risk assessments.

TL;DR: The present study provides the first microplastic field assessment of low-density tire wear particles in estuarine tributaries within the Charleston Harbor estuary.

TL;DR: The results suggest that MP pollution is ubiquitous in the East China Sea, and it is suggested that marine organisms which occupy higher trophic levels might be suitable MP indicator species.

TL;DR: This method was used to test the efficacy of two technologies marketed to reduce microfiber emissions: the Cora Ball and Lint LUV-R filter, and found both significantly reduced the numbers of microfibers from fleece blankets in washing effluent.

TL;DR: It was determined that the mean rate of biodegradation of PHA in the marine environment is 0.04-0.09 mg·day-1·cm-2 (p = 0.05) and that, for example, a PHA water bottle could be expected to take between 1.5 and 3.5 years to completely biodegrade.
