Phuputso ea mefuta e mehlano e fapaneng ea lijo tsa leoatleng e fumane hore sampole ka 'ngoe ea liteko e na le polasetiki e ngata.
Bafuputsi ba ile ba reka li-oyster, shrimp, squid, crabs le sardine 'marakeng Australia' me ba li hlahloba basebelisa mokhoa o sa tsoa ntlafatsoa o ka khethollang le ho metha mefuta e mehlano e fapaneng ea polasetiki.
Phuputso e entsoeng ke Univesithi ea Exeter le Univesithi ea Queensland e fumane hore squid, gram shrimp, shrimp, oysters, shrimp le sardine e ne e le 0.04 mg, 0.07 mg, oyster 0.1 mg, crab 0.3 mg le 2.9 mg, ka ho latellana.
Francesca Ribeiro, mongoli ea ka sehloohong oa QUEX Institute, o itse: “Ha ho nahanoa ka karolelano ea ts'ebeliso, bareki ba lijo tsa leoatleng ba ka ja polasetiki e ka bang 0.7 mg ha ba ja li-oyster kapa squid, ha ho ja sardine ho ka ja ho feta. Ho fihlela 30mg ea polasetiki. "Moithuti oa PhD.
"Ha ho bapisoa, boima ba karolelano ea thollo ka 'ngoe ea raese ke 30 mg.
"Seo re se fumaneng se bontša hore palo ea polasetiki e teng lipakeng tsa mefuta e fapaneng e fapana haholo, le hore ho na le phapang lipakeng tsa batho ba mofuta o le mong.
"Ho tsoa mefuteng ea lijo tsa leoatleng e lekiloeng, sardine e na le polasetiki e phahameng ka ho fetisisa, e leng sephetho se makatsang."
Moprofesa Tamara Galloway, mongoli-'moho le eena oa Exeter Institute for Global Systems, o itse: "Ha re utloisise ka botlalo likotsi tsa ho noa polasetiki bophelong ba batho, empa mokhoa ona o mocha o tla re nolofalletsa ho o fumana."
Bafuputsi ba ile ba reka lijo tse tala tsa leoatleng-makhala a mahlano a maputsoa a hlaha, li-oyster tse leshome, li-prawn tse leshome tse lenngoeng, li-squid tse hlaha tse leshome le sardine tse leshome.
Eaba ba hlahloba li-plastiki tse hlano tse ka khetholloang ka mokhoa o mocha.
Li-plastiki tsena kaofela li sebelisoa haholo lipaketeng tsa polasetiki le masela a maiketsetso, 'me hangata li fumanoa lithong tsa leoatle: polystyrene, polyethylene, polyvinyl chloride, polypropylene le polymethylmethacrylate.
Mokhoa o mocha, lisele tsa lijo li alafshoa ka lik'hemik'hale ho qhala polasetiki e teng sampoleng. Tharollo e hlahisoang e hlahlojoa ho sebelisoa mokhoa o bonolo haholo o bitsoang pyrolysis gas chromatography-mass spectrometry, e ka khethollang mefuta e fapaneng ea polasetiki ka nako e le ngoe.
Polyvinyl chloride e fumanoe mehlala eohle, 'me polasetiki e nang le mohopolo o phahameng ka ho fetisisa e ne e le polyethylene.
Microplastics ke likhechana tsa polasetiki tse nyane haholo tse tla silafatsa likarolo tse ngata tsa lefats'e, ho kenyeletsoa le leoatle. Mefuta eohle ea bophelo ba metsing e a li ja, ho tloha ho liboko tse nyane le plankton ho isa ho liphoofolo tse kholo.
Patlisiso ho fihlela joale e bontšitse hore microplastics ha e kene feela lijong tsa rona ho tsoa lijong tsa leoatleng, empa hape e kena 'meleng oa motho ho tsoa metsing a libotlolo, letsoai la leoatle, biri le mahe a linotši le lerōle le tsoang lijong.
Mokhoa o mocha oa liteko ke mohato o lebisang ho hlaloseng hore na ke lipalo tse kae tsa polasetiki tse nkoang li le kotsi le ho lekola likotsi tse ka bang teng tsa ho kenya polasetiki ea lijo.
