Haufinyane tjena, phuputso e tsoang Univesithing ea McGill e Canada e bontšitse hore mekotla ea tee e lokolla likaroloana tsa polasetiki tse mashome a libilione mochesong o phahameng. Ho hakanngoa hore kopi e 'ngoe le e' ngoe ea tee e entsoeng ka mokotla o mong le o mong oa tee e na le li-microplastic tse limilione tse likete tse 11.6 le likaroloana tsa nanoplastic tse limilione tse likete tse 3.1. Boithuto bona bo phatlalalitsoe ho American Journal of Environmental Science and Technology ka la 25 Loetse.
Ba khethile mekotla e mene ea tee ea polasetiki ka mokhoa o sa reroang: mekotla e 'meli ea nylon le tse peli tsa PET. Haholo-holo, PET e ka sebelisoa maemong a mocheso a 55-60 ℃ nako e telele, 'me e khona ho mamella mocheso o phahameng oa 65 ℃ le mocheso o tlase oa - 70 ℃ ka nako e khuts'oane,' me e na le tšusumetso e nyane ho thepa ea eona ea mochini. mocheso o phahameng le o tlase. Lahla tee, hlatsoa mokotla ka metsi a hloekisitsoeng, ebe u etsisa mokhoa oa ho ritela tee, 'me u kolobise mokotla o se nang letho ka metsi a chesang a 95 ℃ metsotso e 5. Ho hlakile hore metsi ao re etsang tee ke metsi a belang, 'me mocheso o phahame haholo ho feta mefuta e mengata ea tšebeliso ea PET.
Ho lemoha ha McGill ho bontša hore palo e kholo ea likaroloana tsa polasetiki e tla lokolloa pele. Komiki ea mokotla oa tee e ka lokolla li-micron tse ka bang limilione tse likete tse 11.6 le li-nanometer tse limilione tse likete tse 3.1 tsa likaroloana tsa polasetiki! Ho feta moo, hore na likaroloana tsena tsa polasetiki tse lokolotsoeng li chefo ho lintho tse phelang. E le ho utloisisa chefo ea likokoana-hloko, bafuputsi ba ile ba sebelisa li-fleas tsa metsi, invertebrate, e leng sebōpuoa sa mohlala se sebelisetsoang ho hlahloba chefo e teng tikolohong. Ha mokotla oa tee o le ngata haholo, letsetse la metsi le sesa ha le sese haholo. Ha e le hantle, tšepe e boima + ea polasetiki e mpe ho feta likaroloana tsa polasetiki tse hloekileng. Qetellong, letsetse la metsi ha lea ka la shoa, empa le ne le holofetse. Boithuto bona bo fihletse qeto ea hore na likaroloana tsa polasetiki tsa mokotla oa tee li ama bophelo ba motho li hloka lipatlisiso tse ling.
