mikroplastiks
Microplastics are plastic particles smaller than five millimeters in size. They are typically divided into primary microplastics, manufactured at small sizes such as microbeads used in cosmetic products and plastic pellets, and secondary microplastics, produced by the breakdown of larger plastic items through weathering and abrasion.
Environmental presence and fate: Microplastics have been detected in oceans, rivers, soils, sediments, and even the
Sources: Major sources include primary microplastics such as cosmetic beads and plastic pellets; synthetic textile fibers
Biological and health aspects: Many marine and freshwater organisms ingest microplastics, which can cause physical harm
Measurement and regulation: Researchers report concentrations as particles per liter or per kilogram of material; unit
Knowledge gaps: Standardized sampling and analysis, long-term ecosystem and health effects, and fate in soils and
