Ndị nyocha zụtara oyster, oporo, squid, crabs na sardines site n'ahịa dị n'Australia wee nyochaa ha site na iji usoro ọhụụ mepụtara nke nwere ike ịkọwa ma tụọ ụdị plastik dị iche iche n'otu oge.
Nnyocha nke Mahadum Exeter na Mahadum nke Queensland mere gosiri na squid, gram shrimp, shrimp, oysters, shrimp, na sardines bụ 0.04 mg, 0.07 mg, oyster 0.1 mg, nshịkọ 0.3 mg na 2.9 mg.
Francesca Ribeiro, onye isi akwụkwọ nke QUEX Institute, kwuru, sị: “N’ịtụle nkezi nri, ndị na-eri nri mmiri nwere ike iri ihe dịka 0.7 mg nke plastik mgbe ha na-eri oporo ma ọ bụ skwid, ebe iri sardine nwere ike iri karịa. Ihe ruru 30mg plastik. "Nwa akwụkwọ PhD.
"Maka ntụle, nkezi nke ọka osikapa ọ bụla bụ 30 mg.
"Nchọpụta anyị gosiri na etu plastik dị n'etiti ụdị dị iche iche dịgasị iche iche, na enwere ndịiche dị n'etiti ndị otu ụdị.
"Site na ụdị ụdị azụ mmiri a nwalere, sardines nwere ọdịnaya plastik kachasị elu, nke bụ nsonazụ dị ịtụnanya."
Prọfesọ Tamara Galloway, onye na-ede akwụkwọ na Exeter Institute for Global Systems kwuru, sị: "Anyị aghọtachaghị ihe egwu dị na ịtinye plastik na ahụike mmadụ, mana usoro ọhụrụ a ga-eme ka ọ dịrị anyị mfe ịchọpụta."
Ndị ọrụ nyocha ahụ zụtara ahịhịa mmiri ahịhịa-na-acha anụnụ anụnụ ise, oyster iri, okwute iri a kụrụ n'ubi, squid iri na sardine iri.
Mgbe ahụ, ha nyochara plastik ise nwere ike ịmata site na usoro ọhụrụ.
A na-ejikarị plastik ndị a eme ihe na ngwugwu plastik na akwa sịntetik, na-ahụkarị na nsị mmiri: polystyrene, polyethylene, polyvinyl chloride, polypropylene na polymethylmethacrylate.
Na usoro ohuru, a na-eji kemikal agwọ anụ ahụ igbari plastik dị na sample ahụ. A na-enyocha ihe ga-esi na ya pụta site na iji usoro dị oke egwu nke a na-akpọ pyrolysis gas chromatography-mass spectrometry, nke nwere ike ịkọpụta ụdị plastik dị iche iche n'otu oge ahụ.
A hụrụ polyvinyl chloride na ihe atụ niile, na plastik nwere nnukwu mgbatị bụ polyethylene.
Microplastics bụ mpekere plastik pere mpe nke ga-emetọ akụkụ ka ukwuu nke ụwa, gụnyere oke osimiri. Typesdị ndụ mmiri niile na-eri ha, site na obere larvae na plankton ruo na nnukwu mammals.
