Smaller particles are harder to measure and can pose greater biological risks. Fine and ultrafine airborne particles can penetrate deep into the lungs, and some can reach the bloodstream. Understanding their chemistry demands spatial resolution, sensitivity and accurate targeting. What…
Tibetan Plateau is receiving an estimated 56 tons of microplastics annually at altitudes above 4000 metres Potentially toxic microplastic and nanoplastic particles are raining down on Mount Everest year-round, scientists warn in a new study. These ultra-small plastic fragments, less than 5mm in…
Laboratory experiments show that UV-aged polystyrene microplastics can reduce toxic hexavalent chromium through two distinct chemical pathways involving persistent free radicals and microplastic-derived dissolved organic matter. Microplastics have long been treated as passive pollutants, drifting through rivers and oceans while…
U.S. Environmental Protection Agency Administrator Lee Zeldin speaks during a roundtable with U.S. Health and Human Services Secretary Robert F. Kennedy Jr. on efforts to combat forever chemicals at EPA headquarters on May 18 in Washington, D.C. LOS ANGELES — Scientists have found microplastics in virtually…
Microplastics and heavy metals are increasingly found together in agricultural soils, where they threaten crop productivity and raise concerns for human health. The researchers set out to test whether biochar modified with calcium oxide nanoparticles, abbreviated NBC, could blunt the…
Material World is a weekly roundup of innovations and ideas that are reshaping the materials sector. It covers the latest developments in how fashion is designed, engineered, and scaled—from emerging biomaterials and next-generation leathers to engineered fibers and sustainable…
Scientists quantify exact amounts, types of plastics in snowfall For the first time, UC Riverside scientists have measured how much microplastic pollution falls on the Sierra Nevada during snowstorms and were surprised to find significant amounts even in the most…
Research conducted by the University of Memphis explores the potential relationship between clothing materials and airborne microplastic concentrations in the personal breathing zone. MEMPHIS, Tenn., Oct. 29, 2026 /PRNewswire/ -- Preliminary findings from a pilot study conducted at the University of Memphis, suggest…
Plastic that enters the environment does not necessarily make its way to the sea via rivers. In fact, only a tiny fraction eventually reaches river mouths. Most plastic remains on land or within river systems. This is the finding of…
Plastic pollution is an increasingly present threat to marine life and one which can potentially impact your dinner table. Oysters, and other economically valuable shellfish, filter their food from the water where they may also inadvertently capture tiny microplastics. The…
Microplastics in oceans, rivers, lakes, soil, snow and air: where they come from, how they are measured and how they can be removed.
