Researchers at Perm National Research Polytechnic University highlight microplastics as a major contaminant affecting water, soil, air, and living organisms. The university’s science team emphasizes that these tiny particles arise from a wide range of sources and pose risks across ecosystems. This assessment is shared by the university’s press service.

Microplastics are tiny particles ranging from about 5 millimeters down to one micron in size. They enter cosmetics and household products as plastics shed from larger items during use, washing, or breakdown. These fragments can persist in the environment for long periods and accumulate in the food chain. Source: Environmental Health Journal.
Experts estimate the largest sources of microplastics are synthetic textiles, which shed about 35 percent during washing; tire wear adds roughly 28 percent; and urban dust contributes about 24 percent. Additional input comes from road markings, coatings on ships, and glittery decorative cosmetics. Source: International Environmental Review.
These particles travel long distances by wind and water. Lightweight polymers like polyethylene tend to float on the sea surface, while heavier fragments settle into sediments. The tiniest particles become airborne and are inhaled by people and animals. Rain and runoff carry plastics from streets into soils, groundwater, rivers, and oceans, spreading contamination far from their original source. Source: Global Plastics Studies.
Marine creatures mistake microplastics for food, from plankton to fish to seabirds. The particles accumulate in their bodies, disrupt digestion, and can lead to illness or death. Humans ingest plastics through seafood, drinking water, and even air. Research has detected microplastics and associated microbes in human lungs, liver, and kidneys. Source: Aquatic Health Journal.
Beyond the physical presence, plastics can carry toxic chemicals and bacteria. Once inside the body, microplastics may trigger chronic inflammation and contribute to disease processes. Some estimates suggest that swallowed plastic fragments from various consumer products can accumulate to thousands of particles in a typical exposure scenario. Source: Health Sciences Review.
Health and environmental experts advise opting for clothing made from natural fibers, avoiding cosmetics containing microbeads, using reusable bags and glass containers instead of disposable plastics, and checking ingredient lists to limit exposure to BPA and other harmful additives.
