Vsako leto v rekah kro\u017ei ve\u010d milijonov ton plasti\u010dnih odpadkov, ki nato pristanejo v oceanih, kjer zaradi valov in ultravijoli\u010dne svetlobe sonca postopoma razpadejo na manj\u0161e delce.<\/p>\n

Znanstveniki z nem\u0161kega in\u0161tituta Alfred Wegener za polarne in morske raziskave so izvedli raziskavo, ki je pokazala, da lahko delci mikroplastike v zraku prepotujejo ogromne razdalje.<\/p>\n

Ti delci, manj\u0161i od pet milimetrov, nato s padavinami, predvsem s snegom, padejo na tla. Znanstvenica in raziskovalka Melanie Bergmann je dejala: “Jasno je, da ve\u010dina mikroplastike, ki jo najdemo v snegu, pade z neba.”<\/p>\n

Bergmannova in njeni sodelavci so v raziskavi uporabili infrarde\u010de slikanje, da so analizirali vzorce, ki so jih zbrali med letoma 2015 in 2017 s plavajo\u010dega ledu v Grenlandiji. Te so potem primerjali z vzorci iz \u0161vicarskih Alp in Bremna na severozahodu Nem\u010dije.<\/p>\n

Ugotovili so, da je koncentracija delcev mikroplastike na Arktiki ob\u010dutno manj\u0161a kot v Evropi, a \u0161e vedno velika.<\/p>\n

Njihova hipoteza je temeljila na prej\u0161njih raziskavah o cvetnem prahu, v katerih so znanstveniki potrdili, da cvetni prah blizu ekvatorja pristane na Arktiki, tako kot lahko saharski prah prekrije na tiso\u010de kilometrov povr\u0161ine in pristane v severovzhodni Evropi.<\/p>\n

Bergmannova je dejala, da \u0161e niso izvedli veliko raziskav, v katerih bi odkrili vplive izpostavljenosti tem delcem.<\/p>\n

“Ko smo ugotovili, da lahko velika koli\u010dina mikroplastike potuje tudi po zraku, se nam je porodilo vpra\u0161anje, \u010de in koliko plastike vdihujemo,” je dejala in podarila, da so raziskave o vplivih na zdravje ljudi in na \u017eivali nujno potrebne.<\/p>\n","protected":false},"excerpt":{"rendered":"
