Puas yog Daim Npog Ncauj Ncauj Ncauj Ntau Ntawm Cov Teeb Meem Ua paug ntau dua li cov hnab yas?

Cov kev tshawb fawb tsis ntev los no kwv yees tias ntau li 129 billion lub ntsej muag lub ntsej muag tau siv thoob ntiaj teb txhua lub hlis, lossis 3 lab txhua feeb. Feem ntau ntawm cov no yog cov npog ntsej muag uas siv tau los ntawm cov yas microfibers.

"Raws li ntau thiab ntau cov ntawv ceeb toom ntawm mishandled lub qhov ncauj qhov ntswg tshwm sim, muaj ib qho kev xav tau ceev rau tib neeg kom paub txog qhov muaj peev xwm ntawm ib puag ncig kev hem thawj thiab tiv thaiv nws los ntawm kev ua cov teeb meem yas tom ntej," cov kws tshawb fawb tau hais hauv cov lus tawm tswv yim luam tawm hauv phau ntawv xov xwm tshawb fawb Frontiers hauv Environmental Science thiab Engineering.

Cov kws tshawb fawb yog Elvis Genbo Xu, tus kws tshaj lij ntawm ib puag ncig toxicology los ntawm University of Southern Denmark, thiab Jason Ren, tus xibfwb ntawm pej xeem thiab ib puag ncig engineering ntawm Princeton University.

Tsis muaj cov txheej txheem rau kev rov ua daim npog ntsej muag

Cov qhov ncauj qhov ntswg pov tseg yog ib hom yas uas tsis biodegrade yooj yim thiab tuaj yeem tawg ua cov yas me me, hu ua microplastics thiab nanoplastics, uas tau nthuav dav hauv ecosystems.

Cov qhov ncauj qhov ntswg pov tseg yog tsim los ntawm qhov loj me piv rau lub raj mis yas, kwv yees li 43 billion ib hlis.

Txawm li cas los xij, tsis zoo li lub raj mis yas (kwv yees li 25 feem pua ​​​​ntawm cov khoom siv rov ua dua), tsis muaj cov lus qhia tseem ceeb rau kev rov ua dua daim npog ntsej muag, ua rau nws muaj feem ntau dua tias lub qhov ncauj qhov ntswg yuav raug kho raws li cov khoom pov tseg, cov kws tshawb fawb tau sau.

Tseem ceeb tshaj cov hnab yas

Yog tias tsis rov ua dua tshiab zoo li lwm cov pov tseg yas, cov qhov ncauj qhov ntswg pov tseg xaus rau hauv ib puag ncig, cov dej tsis huv, thiab dej hiav txwv, qhov chaw huab cua tsim cov microplastics loj (tsawg dua 5 hli) hauv lub sijhawm luv luv (lub lis piam) thiab cov khoom tawg ntxiv rau hauv nanoplastics (tsawg dua 1 micron).

"Ib qho teeb meem tshiab loj dua yog tias lub qhov ncauj qhov ntswg yog tsim los ntawm microplastic fibers ncaj qha (kwv yees li 1 txog 10 microns tuab). Raws li lub qhov ncauj qhov ntswg tawg hauv ib puag ncig, lawv yuav tso tawm ntau cov microplastics yooj yim dua thiab sai dua li cov hnab yas xws li cov hnab yas, "cov kws tshawb fawb tau sau.

Cov kws tshawb fawb tau hais tias lawv tsis paub yuav ua li cas lub qhov ncauj qhov ntswg tau ua kom pom cov khoom yas loj hauv ib puag ncig, vim tsis muaj cov ntaub ntawv hais txog qhov ncauj qhov ntswg degradation.

"Tab sis peb paub tias, zoo li lwm cov khib nyiab yas, lub qhov ncauj qhov ntswg pov tseg kuj tuaj yeem sib sau thiab tso tawm cov tshuaj phem thiab cov tshuaj lom neeg, xws li bisphenol A, cov hlau hnyav, thiab kab mob- ua rau cov kab mob. Cov no yuav muaj kev cuam tshuam tsis ncaj rau cov nroj tsuag, tsiaj txhu thiab tib neeg." Elvis Genbo Xu hais.
