Oyster Beds and Reefs of the United Arab Emirates

A survey of oyster habitats in the United Arab Emirates found microplastics present in both sediments and oyster tissue despite otherwise good water quality conditions. Since oysters are filter feeders that accumulate contaminants and are consumed by people, their contamination with microplastics raises direct food safety concerns in this coastal region.

Interactive behavior of cadmium ions onto polyethylene microplastics in aquatic system

The presence of microplastics in fishes of South Maldives

Researchers found microplastics in the gut, gills, and flesh of two fish species collected from South Maldives, with 80% of one species containing plastic particles, indicating widespread ingestion by reef fish in this remote island nation and potential transfer into the human food chain.

How does the concentration of microplastics in recycled toilet paper compare to non-recycled toilet paper when tested in a shredded state and controlled laboratory conditions?

Insights Into the Adsorption Behavior of Polyethylene Microplastics Towards Lead(II) Ions

Researchers investigated the adsorption behavior of lead(II) ions onto polyethylene microplastics in freshwater environments by systematically varying initial Pb(II) concentration, pH, and residence time, using scanning electron microscopy and other characterization methods to elucidate the interaction dynamics and sorption mechanisms between this common metal contaminant and microplastic surfaces.

How does the concentration of microplastics in recycled toilet paper compare to non-recycled toilet paper when tested in a shredded state and controlled laboratory conditions?

Researchers compared microplastic concentrations in recycled versus non-recycled toilet paper under controlled laboratory conditions using a standardized shredding protocol, aiming to determine whether the recycling process reduces or increases microplastic content. The study quantified microplastic particle counts in both paper types, contributing evidence on whether recycled paper products represent a meaningful pathway for microplastic exposure via everyday consumer goods.

Microstructure and Microhardness of Chrome-Oxide Coating Precipitating from Gases Phase Using Liquid of Metal Organic Chrome Compositions

This study analyzed how oxygen-containing additives affect the microstructure and microhardness of chromium oxide coatings deposited from metal-organic precursors. The resulting coatings showed excellent adhesion, high microhardness values up to 22 GPa, and improved microplasticity, corrosion resistance, and wear resistance.
