Riparian vegetation as a trap for plastic litter
TLDR
In this paper , the authors investigated the role of vegetation as a plastic trap and the possible detrimental effects of plastic on the plant health status in 8 central Italian rivers. And they found that the highest plastic density was found on the shrubby type suggesting that a tree shape retains plastics more easily than all other vegetated and unvegetated types.About:

Rivers as Plastic Reservoirs
TL;DR: In this paper , the authors introduce the concept of river systems as plastic reservoirs, and focus on the retention mechanisms within different river compartments, and their effect on the fate of the plastics that are accumulated on various timescales.

Polyethylene microplastics interfere with the nutrient cycle in water-plant-sediment systems.
TL;DR: In this paper , a simulation study was performed to analyze the influence of polyethylene (PE) microplastics on the morphological, physiological, and stoichiometric (C, N, P) characteristics of submerged plants, and to investigate their effects on the nutrient cycle and microbial community in freshwater sediment.

Riverine macroplastic gradient along watercourses: A global overview
TL;DR: In this article , the authors analyzed and discussed the bibliometric analysis on macroplastics in rivers providing a framework for plastic pollution management, highlighting the importance of a plastic gradient in the horizontal transport along the entire river course (i.e., three river zones).

Temporal changes of plastic litter and associated encrusting biota: Evidence from Central Italy (Mediterranean Sea).
Giulia Cesarini,Silvia Secco,Corrado Battisti,Beatrice Questino,Leonardo Marcello,Massimiliano Scalici +5 more
TL;DR: In this paper , the authors investigated the temporal changes from spring to summer of the stranded litter and the composition of plastic encrusting biota along an Italian beach, highlighting a higher quantity of litter (average value 1510.67 ± 581.27 items) in spring, particularly plastic material with a composition driven by currents, winds and waves transported from rivers to sea.

First insight into the macroplastic storage in a mountain river: The role of in-river vegetation cover, wood jams and channel morphology.
TL;DR: In this article , the storage of macroplastic debris in a mountain river is controlled by channel management style and resultant river morphology, which modulate river hydrodynamics and a longitudinal pattern of the zones of transport and retention of microplastic conveyed by river flow.

Plastic waste inputs from land into the ocean
Jenna Jambeck,Roland Geyer,Chris Wilcox,Theodore R. Siegler,Miriam E. Perryman,Anthony L. Andrady,Ramani Narayan,Kara Lavender Law +7 more
TL;DR: This work combines available data on solid waste with a model that uses population density and economic status to estimate the amount of land-based plastic waste entering the ocean, which is estimated to be 275 million metric tons.
Journal ArticleDOI
Accumulation and fragmentation of plastic debris in global environments.
TL;DR: Global plastics production and the accumulation of plastic waste are documented, showing that trends in mega- and macro-plastic accumulation rates are no longer uniformly increasing and that the average size of plastic particles in the environment seems to be decreasing.

River plastic emissions to the world's oceans.
Laurent Lebreton,Joost Van Der Zwet,Jan Willem Damsteeg,Boyan Slat,Anthony L. Andrady,Julia Reisser +5 more
TL;DR: A global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information is presented to provide baseline data for ocean plastic mass balance exercises, and assist in prioritizing future plastic debris monitoring and mitigation strategies.

Mechanistic implications of plastic degradation
Baljit Singh,Nisha Sharma +1 more
TL;DR: In this paper, the authors have discussed various types of polymeric degradations along with their mechanisms, which include photo-oxidative degradation, thermal degradation, ozone-induced degradation, mechanochemical degradation, catalytic degradation and biodegradation.

Studies of the effects of microplastics on aquatic organisms: What do we know and where should we focus our efforts in the future?
TL;DR: A critical perspective on published studies of MP ingestion by aquatic biota is provided and there are significant mismatches between the types of MP most commonly found in the environment or reported in field studies and those used in laboratory experiments.
