Znanstvenici splitskog Instituta za oceanografiju i ribarstvo u suradnji s kolegama iz Ujedinjenog Kraljevstva prvi su put rekonstruirali povijest talo\u017eenja mikroplastike u slanim mo\u010dvarama hrvatskog dijela Jadrana analizom slojeva sedimenta kroz vrijeme.<\/p>\n

Slane mo\u010dvare prirodni su spremnici sedimenta te mogu slu\u017eiti kao arhiv plasti\u010dnog otpada. U Mediteranu, a osobito u Jadranu, ekosustavi slanih mo\u010dvara slabo su istra\u017eeni iako je poznato da plastika u njima mo\u017ee postati dio dugoro\u010dnog zapisa ljudskog utjecaja na more, javlja\u00a0Jutarnji list<\/a><\/p>\n

Stoga su znanstvenici na\u0161eg Instituta u suradnji s Liverpool John Moores Universityjem istra\u017eivali koli\u010dinu, tip, starost i uvjete talo\u017eenja mikroplastike te njezinu povezanost s organskom tvari i tipom sedimenta. Rezultati ovog istra\u017eivanja objavljeni su u me\u0111unarodnom znanstvenom \u010dasopisu\u00a0Microplastics<\/a>\u00a0\u2014 objavili su s Instituta.<\/p>\n

Uzimane su sedimentne jezgre s lokacija u Morinjskom zaljevu kod \u0160ibenika i Blaca kod u\u0161\u0107a Neretve, rezane po centimetru kako bi se dobio vremenski zapis talo\u017eenja. Slojevi su datirani radiokarbonskim i radionuklidnim metodama, mikroplastika je izdvajana i analizirana mikroskopom te infracrvenim spektrometrom za identifikaciju plastike koji posjeduje njihov Laboratorij za kemijsku oceanografiju i sedimentologiju mora. Paralelno su odre\u0111ivani geokemijski parametri: organska tvar, ugljik, du\u0161ik, oblici fosfora i veli\u010dina zrna sedimenta te su provedene statisti\u010dke analize u svrhu detekcije povezanosti mikroplastike i karakteristika sedimenta.<\/p>\n

Iz rezultata je vidljivo da se mikroplastika u Morinjskom zaljevu pojavljuje ve\u0107 oko 1950., a u Blacama nakon 1960., pri \u010demu koncentracije rastu prema novijim slojevima sedimenta, prate\u0107i globalni porast proizvodnje plastike. U Morinjskom zaljevu ve\u0107e su vrijednosti (do 0,5 \u010destica po gramu) i dominiraju vlakna povezana s urbanim i pomorskim izvorima, dok su u Blacama koncentracije ni\u017ee (do 0,05 \u010destica po gramu) i prevladavaju fragmenti povezani s lokalnim izvorima poput poljoprivrede i ambala\u017ee, javlja\u00a0Jutarnji list<\/a><\/p>\n

\u2014 U usporedbi s drugim europskim lokalitetima, gdje su zabilje\u017eene koncentracije i do 2\u20133 \u010destice po gramu sedimenta, vrijednosti na hrvatskoj obali znatno su ni\u017ee, \u0161to upu\u0107uje na manji intenzitet ljudskog pritiska, ali ipak jasno pokazuje da su i na\u0161i obalni sustavi dio globalnog problema \u2014 pojasnili su s Instituta.<\/p>\n
