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…
Three cell types—from the liver (HepG2), skin and connective tissue (Fibroblasts), and intestinal lining (Caco-2)—were selected to create a multi-tissue exposure platform based on their roles in the body's defenses against toxin exposure. Each cell type was evaluated under…
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…
Newswise — Washington D.C. -- A newly published study advances our knowledge of how microplastics may age in the environment and whether they stick to other contaminants as they do so. Microplastics (MPs) are tiny plastic pieces that measure less than five millimeters…
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…
In a recent study published in the journal Scientific Reports, researchers investigated associations between seafood intake and persistent chemical burden among Korean adults. In the present study, the researchers assessed associations between seafood intake and persistent chemicals and between these…
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…
A mouse study finds chronic polystyrene nanoplastic exposure promotes colorectal tumorigenesis by depleting a protective gut bacterium and weakening Th17 cell immunity. Polystyrene nanoplastics, among the most pervasive environmental contaminants, may actively promote colorectal cancer rather than merely passing through the…
The answer to both questions was yes, with distinct mutational fingerprints emerging for each material. Mesoporous silica killed cells in a clean, dose-dependent fashion, while graphene oxide produced a messier toxicity profile—but both left measurable scars in a reporter…
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…
Microplastics and nanoplastics found in blood, brains, organs, food and drinking water, and what research says about their effects on health.
