TLDR
The uptake and tissue accumulation of polystyrene microplastics in zebrafish were detected, and the toxic effects in liver were investigated, showing that both 5 μm and 70 nm PS-MPs caused inflammation and lipid accumulation in fish liver.Abstract:
Microplastics have become emerging contaminants, causing widespread concern about their potential toxic effects. In this study, the uptake and tissue accumulation of polystyrene microplastics (PS-MPs) in zebrafish were detected, and the toxic effects in liver were investigated. The results showed that after 7 days of exposure, 5 μm diameter MPs accumulated in fish gills, liver, and gut, while 20 μm diameter MPs accumulated only in fish gills and gut. Histopathological analysis showed that both 5 μm and 70 nm PS-MPs caused inflammation and lipid accumulation in fish liver. PS-MPs also induced significantly increased activities of superoxide dismutase and catalase, indicating that oxidative stress was induced after treatment with MPs. In addition, metabolomic analysis suggested that exposure to MPs induced alterations of metabolic profiles in fish liver and disturbed the lipid and energy metabolism. These findings provide new insights into the toxic effects of MPs on fish.read more

Distribution and importance of microplastics in the marine environment: A review of the sources, fate, effects, and potential solutions
TL;DR: The sources and global distribution of microplastics in the environment, the fate and impact on marine biota, especially the food chain are described and the control measures discussed are those mapped out by both national and international environmental organizations for combating the impact from microplastic pollution.

Microplastics in freshwater systems: A review on occurrence, environmental effects, and methods for microplastics detection.
TL;DR: There is still no universal accepted quantification and qualification tools of microplastics in fresh waters, and more work is anticipated to obtain accurate information on microplastic in freshwater, which can then be used for the better assessment of the environmental risk.

TL;DR: Analysis of zebrafish Danio rerio and nematode Caenorhabditis elegans used as model organisms for microplastic exposure in freshwater pelagic and benthic environments suggests intestinal damage is a key effect of microplastics; and that the toxicity ofmicroplastics is closely dependent on their size, rather than their composition.

Accumulation of Microplastic on Shorelines Woldwide: Sources and Sinks
Mark Anthony Browne,Mark Anthony Browne,Mark Anthony Browne,Phillip Crump,S. J. Niven,Emma L. Teuten,Andrew Tonkin,Tamara S. Galloway,Richard C. Thompson +8 more
TL;DR: It is shown that microplastic contaminates the shorelines at 18 sites worldwide representing six continents from the poles to the equator, with more material in densely populated areas, but no clear relationship between the abundance of miocroplastics and the mean size-distribution of natural particulates.

TL;DR: It is shown that microplastics are ingested by, and may impact upon, zooplankton, and imply that marine microplastic debris can negatively impact upon zoopLankton function and health.

TL;DR: The data indicate as plastic fragments into smaller particles, the potential for accumulation in the tissues of an organism increases and further work using a wider range of organisms, polymers, and periods of exposure will be required to establish the biological consequences of this debris.

Uptake and effects of microplastics on cells and tissue of the blue mussel Mytilus edulis L. after an experimental exposure
TL;DR: Proof of principle is provided that microplastics are taken up into cells and cause significant effects on the tissue and cellular level, which can be assessed with standard cytochemical biomarkers and polarized light microscopy for microplastic tracking in tissue.
