I-Xinhua News Agency, i-Wellington, ngo-September 24 (Intatheli uLu Huaiqian kanye no-Guo Lei) Ithimba labacwaningi abavela eNyuvesi yase-Otago eNew Zealand lithole ukuthi izingxenye ezintathu kwezine zezinhlanzi zasendle ezingaphezu kuka-150 ezibanjwe endaweni yolwandle eningizimu yeNew Zealand zinama-microplastics. .
Besebenzisa i-microscopy kanye ne-Raman spectroscopy ukutadisha amasampuli angu-155 ezinhlanzi zasolwandle ezibalulekile ezithengiswayo ezingu-10 ezibanjwe ogwini lwase-Otago esikhathini esingaphezu konyaka, abacwaningi bathola ukuthi amaphesenti angu-75 ezinhlanzi ezicwaningiwe aqukethe ama-microplastics, isilinganiso sama-75 inhlanzi ngayinye.2.5 izinhlayiya microplastic zatholwa, futhi 99.68% izinhlayiya zepulasitiki ezihlonziwe zazincane kuno-5 mm ngosayizi.Imicu ye-Microplastic iwuhlobo oluvame kakhulu.
Ucwaningo lwathola amazinga afanayo we-microplastics ezinhlanzini ezihlala ekujuleni okuhlukene emanzini okukhulunywe ngawo ngenhla, okuphakamisa ukuthi ama-microplastics atholakala yonke indawo emanzini afundwayo.Abacwaningi bathi ucwaningo olwengeziwe luyadingeka ukuze kutholwe ubungozi empilweni yomuntu kanye nemvelo ngokudla izinhlanzi ezingcoliswe ngopulasitiki.
Ama-Microplastic ngokuvamile abhekisela ezinhlayiyeni zepulasitiki ezincane kuno-5 mm ngosayizi.Ubufakazi obuningi bubonisa ukuthi ama-microplastics angcolise imvelo yasolwandle.Ngemva kokuba le mfucumfucu ingene ohlelweni lokudla, izogeleza ibuyele etafuleni lomuntu futhi ibeke impilo yomuntu engozini.
Imiphumela yocwaningo yashicilelwa kumagazini omusha we-UK Marine Pollution Bulletin.
