Daraasad laga sameeyay shan nooc oo kala duwan oo ah cuntada badda ayaa lagu ogaaday in muunad kasta oo tijaabo ah ay ku jirto xaddi yar oo caag ah.
Baarayaasha ayaa ka iibsaday lohod, shrimp, squid, carsaanyo iyo sardineyn suuq kuyaala Australia waxayna ku lafa gureen iyagoo adeegsanaya qaab cusub oo la soo saaray oo isla markaa lagu garan karo laguna cabiro shan nooc oo caag ah oo kala duwan.
Daraasadan oo ay sameeyeen jaamacada Exeter iyo jaamacada Queensland ayaa lagu ogaaday in xayawaano, gram shrimp, shrimp, oysters, shrimp, iyo sardines ay yihiin 0.04 mg, 0.07 mg, loyst 0.1 mg, carsaanyo 0.3 mg iyo 2.9 mg.
Francesca Ribeiro, oo ah qoraaga hormoodka ah ee machadka QUEX, ayaa tiri: “Iyadoo la tixgelinayo iskucelceliska isticmaalka, macaamiisha cunada baddu waxay cuni karaan qiyaastii 0.7 mg oo caag ah markay cunayaan lows ama squid, halka cunista sardines laga yaabo inay inbadan cunaan. Ilaa 30mg oo balaastig ah. "Ardayga PhD.
Marka la barbardhigo, celceliska miisaanka hadhuudh kasta oo bariis ah waa 30 mg.
Natiijooyinkayagu waxay muujinayaan in qadarka balaastigga ah ee ka dhexeeya noocyada kala duwan uu si aad ah u kala duwan yahay, iyo inay jiraan kala duwanaansho u dhexeeya shakhsiyaadka isku nooc ah.
"Noocyada laga helo cuntada badda ee la tijaabiyo, sardines waxay leedahay waxyaabaha ugu badan ee balaastigga ah, taas oo ah natiijo la yaab leh."
Professor Tamara Galloway, oo ah qoraa ka tirsan machadka Exeter Institute for Global Systems, ayaa yiri: "Si buuxda uma fahmin khataraha ay leedahay in la cuno caagagga caafimaadka aadanaha, laakiin qaabkan cusub ayaa noo sahlaya inaan ogaanno."
Baarayaasha waxay soo iibsadeen cunno ceyriin ah-shan shabaq buluug ah oo duurjoog ah, toban oyster, toban tiger oo beeraley ah, toban duurjoog ah iyo toban sardin.
Kadib, waxay falanqeeyeen shan caag ah oo lagu aqoonsan karo habka cusub.
Dhamaan balaastigani waxaa badanaa loo isticmaalaa baakadaha caaga ah iyo dharka la isku qurxiyo, waxaana badanaa laga helaa qashinka badda: polystyrene, polyetylen, polyvinyl chloride, polypropylene iyo polymethylmethacrylate.
Qaabka cusub, nudaha cuntada waxaa lagu daaweeyaa kiimikooyin si loo kala diro caaga ku jira muunada. Xalka la soo saaray ayaa la falanqeeyay iyadoo la adeegsanayo farsamo aad xasaasi u ah oo loo yaqaan 'pyrolysis gas chromatography-mass spectrometry', taas oo isku mar la aqoonsan karo noocyada kala duwan ee balaastikada ku jira shaybaarka.
Polyvinyl chloride waxaa laga helay dhammaan shay-baarka, balaastigga ugu sareeyay wuxuu ahaa polyetylen.
Microplastics waa jajab aad u yar oo balaastig ah oo wasakheyn doona inta badan dhulka, oo ay ku jirto badda. Dhammaan noocyada nolosha badda waxay cunaan iyaga, laga soo bilaabo dirxiga yaryar iyo plankton illaa naasleyda waaweyn.
Cilmi baaris illaa iyo hadda la sameeyay waxay muujisay in microplastics-ka uusan ka galeynin kaliya cuntadeena cuntada badda, laakiin sidoo kale wuxuu jirka bini'aadamka ka galayaa biyaha dhalada ku jira, cusbada badda, biirka iyo malabka, iyo boodhka cuntada.
Qaabka tijaabada cusub ayaa ah talaabo loo qaadayo qeexida inta raad caag ah ee loo arko inay waxyeello leedahay iyo qiimeynta halista suurtagalka ah ee lagu liqi karo inta caag ah ee raashinka ku jirta.
