Microplastics

noun (usually plural; the singular "microplastic" also functions attributively as a modifier, e.g. "microplastic pollution")
/ˌmaɪkroʊˈplæstɪks/
Tiny plastic particles less than 5 millimetres in diameter, originating from the fragmentation of larger plastic debris, industrial processes (plastic pellets or "nurdles"), synthetic textile fibres released during washing, and microbeads in cosmetics -- pervasive in marine environments, freshwater systems, soil, and even the atmosphere, ingested by organisms at every trophic level and entering the human food chain.

✍️ Usage in a UPSC answer

India's accession to the global plastics treaty negotiations will ring hollow unless domestic regulation moves beyond visible litter to confront microplastics, which now permeate the food chain, drinking water and even human placental tissue, demanding an integrated response spanning environmental governance, public health policy and extended producer responsibility.

🔡 Root

Greek mikros (μικρός) = small; micro- prefix; Greek plastikos = capable of being moulded

📜 Etymology

From Greek mikros (μικρός, "small") + English plastics (from Greek plastikos, "capable of being moulded"); the term gained scientific and public attention in the early 2000s when marine researchers documented the ubiquity of microscopic plastic fragments in ocean samples, leading to growing concern about their ecological and human health impacts.

🧠 Memory Hook

"Micro" (tiny) + "plastic" — picture plastic ground so small it slips through every filter, into the fish, into your water. "Micro = too small to see, too widespread to escape."
