Microplastics in Polar Samples [PDF]

, 2020
Microplastics are increasingly recognized as being globally widespread, but relatively little is known about the presence and abundance of microplastics in samples collected in Polar Regions. Here we review the current knowledge about microplastic occurrence and distribution in polar environments, with a particular focus on the relevance of the data ...

Microplastics and their environmental effects

Environmental Toxicology and Pharmacology, 2023
Microplastics (MPs) are acknowledged as emerging contaminants that pose a substantial threat to the environment. The adverse impacts of MP pollution extend across marine, freshwater, and terrestrial ecosystems, covering regions from the Tropics to the Poles. Although our comprehension of MP behavior has progressed in recent years, it is still difficult

Microplastic and charred microplastic in the Faafu Atoll, Maldives

Marine Pollution Bulletin, 2018
Microplastics are recognized as a growing threat for the marine environment that may even affect areas generally considered pristine. In this work we surveyed the microplastic contamination in the Faafu Atoll (Maldives, Indian Ocean) across twelve sampling station, located either inside or outside the reef rim.

Microplastics and Nanoplastics in Atheromas and Cardiovascular Events.

New England Journal of Medicine
BACKGROUND Microplastics and nanoplastics (MNPs) are emerging as a potential risk factor for cardiovascular disease in preclinical studies. Direct evidence that this risk extends to humans is lacking.

Microplastic debris in sandhoppers

Estuarine, Coastal and Shelf Science, 2013
Adults of the sandhopper Talitrus saltator were fed with dry fish food mixed with polyethylene microspheres (diameter 10-45 mu m). Observations of homogenized guts revealed the presence of microspheres independently of their dimensions. The gut resident time (GRT) was recorded and most of the microspheres are expelled in 24 h.

Microplasticity in Elgiloy [PDF]

Journal of Materials Science, 1985
The room temperature microstrain characteristics of Elgiloy (composition in wt%, 40 Co, 20 Cr, 15 Ni, 7 Mo, 2 Mn, 0.1 C, balance Fe) have been determined for a range of microstructures corresponding to various alloy treatments reported previously. The friction stress was found to be constant (σ F=12±3 MN m−2) for the solution treated (after prestrain),
