Siv microscopy thiab Raman spectroscopy los kawm 155 cov qauv ntawm 10 cov ntses tseem ceeb hauv kev lag luam tau ntes tau tawm ntawm ntug dej hiav txwv Otago ntau tshaj li ib xyoos, cov kws tshawb fawb pom tias 75 feem pua ntawm cov ntses kawm muaj microplastics, qhov nruab nrab ntawm 75 ib tus ntses.2.5 microplastic hais tau raug kuaj pom, thiab 99.68% ntawm cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj yog me dua 5 hli.Microplastic fibers yog hom ntau tshaj plaws.
Txoj kev tshawb nrhiav pom cov qib zoo sib xws ntawm microplastics hauv cov ntses nyob ntawm qhov tob sib txawv hauv cov dej tau hais tseg, qhia tias microplastics muaj nyob thoob plaws hauv dej kawm.Cov kws tshawb fawb hais tias kev tshawb fawb ntxiv yog tsim nyog los txiav txim siab txog kev pheej hmoo rau tib neeg kev noj qab haus huv thiab kev noj qab haus huv los ntawm kev noj cov ntses uas muaj kab mob.
Microplastics feem ntau xa mus rau cov khoom yas me me dua 5 hli.Ntau thiab ntau cov pov thawj qhia tau hais tias microplastics tau ua phem rau thaj chaw marine ecological.Tom qab cov khib nyiab no nkag mus rau hauv cov khoom noj, lawv yuav ntws rov qab mus rau tib neeg lub rooj thiab ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.
Cov txiaj ntsig kev tshawb fawb tau luam tawm nyob rau hauv qhov teeb meem tshiab ntawm UK's Marine Pollution Bulletin.
