TL;DR: It is noted that face masks are easily ingested by higher organisms, such as fishes, and microorganisms in the aquatic life which will affect the food chain and finally chronic health problems to humans, as a result, microplastic from the face mask should be a focus worldwide.

TL;DR: This review quantifies plastic interaction in marine biota by summarized entanglement and ingestion records for all marine birds, mammals, turtles, fish, and invertebrate species, and the frequency of occurrence of ingestion per species (Sp-%FO) was extracted for marine Birds, mammals and turtles.

TL;DR: Quantitative assessments are needed of MP flux rates (g m-2 year-1) in a range of sedimentary environments and Fibres are the dominant MP type and account for 90% of MP on beaches and 49% of particles in tide-dominated estuaries.

TL;DR: The preliminary results indicate that sea ice has the potential to serve as a reservoir for MP debris in the Southern Ocean, which may have consequences for Southern Ocean food webs and biogeochemistry.

TL;DR: The purpose of this review is to analyze the potential impacts of desalination and brine treatment on the environment and suggest mitigation measures.

TL;DR: In this article, a review highlights the toxicity of micro and nanoplastics on marine organisms, biodegradation of plastics and futuristic research needs to solve the issues of plastic pollution in marine environment.

TL;DR: The role of two different wastewater treatment technologies in the abatement of microplastics from the final effluent of an urban wastewater treatment plant (WWTP) is discussed, i.e., membrane bioreactor technology (MBR) and rapid sand filtration (RSF).

TL;DR: People's knowledge and understandings of microplastics; the role of media in framing perceptions and socio-cultural dimensions to popular solutions to reduce single-use plastics are explored; and science communicators, NGOs, industry and policy makers must take account of media representations and the culturally embedded nature of plastics in society.

TL;DR: Th threats of marine microplastics to ocean carbon sequestration are discussed and the potential scale and scope of this impact is explored, and its underlying mechanisms are explored.

TL;DR: This study investigates the presence of microplastics in surface seawater and zooplankton at five different locations off the Terengganu coast in Malaysia, southern South China Sea, finding fibers, which are identified as polyamide are the main type of micro Plastics that dominate in seawater.

TL;DR: How particle size is a key factor in plastic particulate toxicity is highlighted, with microplastics and microfibres observed in the digestive glands with significantly higher plastic concentrations after 7-days exposure, indicative of a heightened immune response.

TL;DR: The diversity of MP shapes and polymeric identities in beluga points to a complex source scenario, and ultimately raises questions regarding the significance and long-term exposure of this pollutant in this ecologically and culturally valuable species.

TL;DR: In the fish group feeding on microplastics, it was found that leukocyte infiltration and hyperemia were more severe in the higher exposure group compared to the lower exposure; and crypt cell loss and villi cell loss increased significantly due to Poly(styrene-co-divinylbenzene) microplastic physical abrasion.

TL;DR: Sediment cores collected from >2000 m water depth in the Rockall Trough revealed a significant negative trend was observed in the frequency of microplastics with increasing sediment age, however there was an increase in polymer diversity, suggesting interstitial transport via pore waters.

TL;DR: Influent and effluent discharges from three WWTPs in Mersin Bay, Turkey were sampled at monthly intervals over a one-year period during 2017, showing that despite their ability to remove 55-97% of microplastics,WWTPs are one of the main sources of micro Plastics to the northeast Mediterranean Sea.

TL;DR: This study investigates the mean concentration and characteristics of macroplastics, mesoplastics and microplastics on eight sandy beaches along the shoreline of Tuticorin, Tamil Nadu, finding correlation established between the degree of recreational activity and the concentrations of meso- and microPLastics.

TL;DR: The present study found that the adsorption processes were following the Freundlich model, and the interaction metal-microplastic was physisorption.

TL;DR: Human intake estimation of MPs showed the possibility of plastics absorption by humans who consume canned fish several times/week, showing the importance of MPs' guidelines for food safety and hygiene.

TL;DR: Microplastics ingested by two bivalve species Perna viridis and Meretrix meretrix collected from three estuaries viz.

TL;DR: Estuaries, mangroves, and seagrass meadows had the highest footprint among the habitats assessed, and a total of 27 threatened coastal species occur within the area impacted by the oil residue.

TL;DR: It is confirmed that, under swash-like mixing with coarse sediments, the MPs tend to burry below the sediment surface, similar to that for MPs floating at the ocean surface.

TL;DR: Assessment of MP levels in the urban coastal environment of Suva, the capital of the Republic of Fiji found that species ingestion of MP was high and associated with MP in sediments, and these MP were associated to land based human activities.

TL;DR: Fourier transform infrared (FTIR) spectroscopy analysis proved the attachment of nanoplastics to microalgae and rearrangement of extracellular polymeric substances and cellular stress appeared as increased cell size, deformed cell wall and increased volume of starch grains.

TL;DR: Nylon, acrylic, and ionomer surlyn were most abundant polymer types in the bay environment, followed by fragment and pellet, and high amount of MP retention was observed in the zooplankton community.

TL;DR: Results show that NPs can adversely affect fish at different stages of development, with reported accumulation in tissues, decreased locomotor and foraging activities, effects on growth and the immune system and alterations on lipid metabolism and neurotoxicity.

TL;DR: Results of the study confirmed prevalence of microplastics in the Persian Gulf, and findings suggested a pressing need to investigate their effects on marine life and human health.

TL;DR: Abundance of the MP was highest in the Wonorejo coast sediment (590 particles/kg dry weight), and the MP particles consisted of 68% large and 25% small sizes and comprised 56.7% polyester, 24.6% low-density polyethylene, and 18.8% polypropylene.

TL;DR: The results showed an early stage of degradation of plastic polypropylene because of abiotic factors, and the surface morphology of plastic changed, indicating the disorientation of the plastic.

TL;DR: The present results revealed an alarming level of microplastics present on Peruvian sandy beaches, but information about the sources, local dynamics and impacts ofMicroplastic pollution in this region are scarce, and thus further research is needed.

TL;DR: Quality assurance measures should be more strictly applied when working with airborne fibers and microplastics, while more research should focus on the factors involved in the variation of concentrations and characteristics of airborne fibers.
