Ba sebelisa microscopy le Raman spectroscopy ho ithuta lisampole tse 155 tsa litlhapi tse 10 tsa bohlokoa tsa leoatleng tse ts'oetsoeng lebopong la Otago ka nako e fetang selemo, bafuputsi ba fumane hore karolo ea 75 lekholong ea litlhapi tse ithutoang li na le li-microplastics, karolelano ea 75 tlhapi ka 'ngoe.Ho ile ha fumanoa likaroloana tsa 2.5 tsa microplastic, 'me 99.68% ea likaroloana tsa polasetiki tse khethiloeng li ne li le nyenyane ho feta 5 mm ka boholo.Li-microplastic fibers ke mofuta o tloaelehileng haholo.
Boithuto bona bo fumane maemo a ts'oanang a li-microplastic ho litlhapi tse phelang botebong bo fapaneng metsing a boletsoeng ka holimo, a fana ka maikutlo a hore li-microplastics li fumaneha hohle metsing a ithutoang.Bafuputsi ba re lipatlisiso tse ling lia hlokahala ho fumana likotsi bophelong ba batho le tikolohong ea ho ja litlhapi tse silafalitsoeng ke polasetiki.
Li-microplastics hangata li bua ka likaroloana tsa polasetiki tse nyane ho feta 5 mm ka boholo.Bopaki bo ntseng bo eketseha bo bontša hore li-microplastic li silafalitse tikoloho ea leoatle.Ka mor’a hore litšila tsena li kene ketane ea lijo, li tla khutlela tafoleng ea batho ’me li behe bophelo ba batho kotsing.
