Nj\u00eb studim i ri zbuloi se njer\u00ebzit po konsumojn\u00eb mbi 240 mij\u00ebgrimca plastike t\u00eb padukshme me \u00e7do lit\u00ebr uj\u00eb n\u00eb shishe, 10 deri n\u00eb 100 her\u00eb m\u00eb shum\u00eb se sa ishte vler\u00ebsuar m\u00eb par\u00eb.<\/span><\/p>\n

Nj\u00eb lit\u00ebr uj\u00eb n\u00eb nj\u00eb shishe plastike u zbulua se p\u00ebrmban mesatarisht 240,000 grimca, tregoi nj\u00eb studim i publikuar s\u00eb fundmi. Shumica e k\u00ebtyre jan\u00eb nanogrimca t\u00eb cilat kan\u00eb potencialin t\u00eb dep\u00ebrtojn\u00eb n\u00eb qelizat njer\u00ebzore dhe t\u00eb hyjn\u00eb n\u00eb qarkullimin e gjakut dhe organet kryesore.<\/span><\/p>\n

Gjetjet e fundit, t\u00eb botuara n\u00eb revist\u00ebn Proceedings of the National Academy of Sciences (PNAS), tregojn\u00eb shtrirjen e plastik\u00ebs n\u00eb ujin n\u00eb shishe, e cila ishte shum\u00eb e n\u00ebnvler\u00ebsuar n\u00eb studimet e m\u00ebparshme.<\/span><\/p>\n

Nd\u00ebrsa mikroplastikat jan\u00eb gjetur kudo, nga pikat m\u00eb t\u00eb thella n\u00eb oqean e deri te brenda trupave tan\u00eb q\u00eb nga lindja, \u00e7do shishe m\u00eb par\u00eb besohej se p\u00ebrmbante mesatarisht vet\u00ebm 325 cop\u00eb grimca.<\/span><\/p>\n

Por ky studim i ri nga studiues nga Universiti i Columbias n\u00eb SHBA tregon se prania e grimcave plastike \u00ebsht\u00eb af\u00ebrsisht nj\u00ebqind her\u00eb m\u00eb shum\u00eb se kaq, duke sfiduar normat e pranuara m\u00eb par\u00eb rreth siguris\u00eb s\u00eb ujit n\u00eb shishe.<\/span><\/p>\n

Shumica e k\u00ebtyre grimcave vinin nga vet\u00eb shishja, sipas autor\u00ebve. K\u00ebto jan\u00eb grimca q\u00eb jan\u00eb m\u00eb pak se nj\u00eb mikron n\u00eb madh\u00ebsi.<\/span><\/p>\n

Studiuesit p\u00ebrdor\u00ebn pes\u00eb mostra nga tre marka t\u00eb ujit n\u00eb shishe n\u00eb SHBA dhe zbuluan se nivelet e grimcave plastike shkonin nga 110,000 n\u00eb 400,000 p\u00ebr lit\u00ebr, mesatarisht rreth 240,000 nga shtat\u00eb lloje t\u00eb plastik\u00ebs.<\/span><\/p>\n

Autor\u00ebt nuk pranuan t\u00eb p\u00ebrmendnin se cilat marka u p\u00ebrdor\u00ebn si mostra.<\/span><\/p>\n

P\u00ebraf\u00ebrsisht 90 p\u00ebr qind e k\u00ebtyre grimcave u identifikuan si nanoplastik\u00eb dhe pjesa tjet\u00ebr ishin mikroplastik\u00eb. Nanogrimcat jan\u00eb m\u00eb pak se nj\u00eb e shtat\u00ebdhjeta e gjer\u00ebsis\u00eb s\u00eb flokut t\u00eb njeriut, aq t\u00eb vogla sa nuk mund t\u00eb shihen n\u00ebn mikroskop.<\/span><\/p>\n

Studiuesit duhej t\u00eb shpiknin nj\u00eb teknologji p\u00ebr t\u00eb p\u00ebrcaktuar sasin\u00eb e k\u00ebtyre grimcave t\u00eb vogla p\u00ebr t\u00eb qen\u00eb n\u00eb gjendje t\u00eb num\u00ebronin dhe analizonin struktur\u00ebn kimike t\u00eb nanogrimcave n\u00eb ujin n\u00eb shishe.<\/span><\/p>\n

Nd\u00ebrsa shkenc\u00ebtar\u00ebt e dinin se nanoplastika ekzistonte n\u00eb ujin e ambalazhuar, Naixin Qian, nj\u00eb studente doktorature n\u00eb kimi n\u00eb Universitetin e Columbias dhe autore kryesore e punimit t\u00eb ri tha “p\u00ebrpara studimit ton\u00eb, njer\u00ebzit nuk kishin nj\u00eb num\u00ebr t\u00eb sakt\u00eb se sa”.<\/span><\/p>\n

Studimet e m\u00ebparshme treguan se nanogrimcat e plastik\u00ebs mund t\u00eb hyjn\u00eb n\u00eb qeliza dhe inde n\u00eb organet kryesore, t\u00eb l\u00ebvizin p\u00ebrmes qarkullimit t\u00eb gjakut dhe t\u00eb p\u00ebrhapin kimikate sintetike potencialisht t\u00eb d\u00ebmshme n\u00eb trup, duke arritur n\u00eb gjak, m\u00ebl\u00e7i dhe tru.<\/span><\/p>\n

Nd\u00ebrsa ndikimet e mundshme t\u00eb k\u00ebtyre nanogrimcave jan\u00eb t\u00eb njohura, studiuesit nuk jan\u00eb t\u00eb sigurt n\u00ebse k\u00ebto gjetje e b\u00ebjn\u00eb ujin n\u00eb shishe m\u00eb t\u00eb rreziksh\u00ebm.<\/span><\/p>\n
