Au trecut aproape 20 de ani de c\u00e2nd cercet\u0103torii au descoperit pericolul reprezentat de microplastice - majoritatea studiilor s-au concentrat asupra vie\u021bii marine. <\/p>\n\n\n\n

Orice fragment de plastic cu o lungime mai mic\u0103 de 5 milimetri este numit microplastic.<\/p>\n\n\n\n

La \u00eenceputurile cercet\u0103rii microplasticului, cercet\u0103torii au lucrat \u00een principal pe microperle \u0219i pelete de plastic virgin care nu puteau fi modelate \u00een produse, inclusiv buc\u0103\u021bi de resturi mari sau sticle sparte care se deteriorau \u00eencet.<\/p>\n\n\n\n

Ace\u0219ti poluan\u021bi se vars\u0103 \u00een r\u00e2uri \u0219i contamineaz\u0103 oceanele. Oceanografii estimeaz\u0103 c\u0103 apele de suprafa\u021b\u0103 ale P\u0103m\u00e2ntului con\u021bin \u00eentre 15 trilioane \u0219i 51 trilioane de particule de plastic.<\/p>\n\n\n\n

C\u00e2teva sute de studii au eviden\u021biat prezen\u021ba microplasticelor \u00een organismele acvatice. \u00cen plus, de atunci au fost identificate numeroase surse de microplastice, cum ar fi particulele de plastic transportate de vehicule pe \u0219osele \u0219i fibrele sintetice aruncate de \u00eembr\u0103c\u0103minte. <\/p>\n\n\n\n

\u00cen plus, oamenii ingereaz\u0103 sau inhaleaz\u0103 plastic din surse neidentificate, deoarece resturile sunt purtate de v\u00e2nt \u00eentre mare \u0219i uscat. De asemenea, este important s\u0103 se stabileasc\u0103 dac\u0103 buc\u0103\u021bile mici de plastic au sau nu efecte negative asupra oamenilor sau animalelor. <\/p>\n\n\n\n

Prin m\u0103surarea expunerii la poluare, autorit\u0103\u021bile de reglementare \u00een domeniul mediului fac un prim pas spre cuantificarea riscurilor pentru s\u0103n\u0103tate. Av\u00e2nd \u00een vedere cre\u0219terea concentra\u021biilor de microplastice \u0219i alte tulbur\u0103ri care pot fi cauzate de consumul de fructe de mare, acest lucru a reprezentat un motiv de \u00eengrijorare major\u0103 \u0219i noi evolu\u021bii \u00een cazurile de probleme respiratorii.<\/p>\n\n\n\n

Cum anume d\u0103uneaz\u0103 microplasticele?<\/strong><\/h2>\n\n\n\n

Cauzele \u0219i efectele acestor particule de plastic au f\u0103cut obiectul mai multor studii. \u00cen func\u021bie de dimensiunea lor sau de capacitatea de a p\u0103trunde \u00een \u021besuturi sau celule, acestea pot provoca irita\u021bii prin simpla lor prezen\u021b\u0103.<\/p>\n\n\n\n

Nanoplasticele, cele mai mici particule, cu un diametru mai mare de un micrometru, reprezint\u0103 cea mai mare preocupare pentru cercet\u0103tori. Dac\u0103 exist\u0103 efecte negative rezultate din toxicitatea chimic\u0103 a microplasticelor, acestea tind s\u0103 aib\u0103 dimensiuni mai mari.<\/p>\n\n\n\n

Mul\u021bi aditivi utiliza\u021bi la fabricarea materialelor plastice prezint\u0103 un risc pentru s\u0103n\u0103tate prin impactul negativ asupra sistemului endocrin. Cu toate acestea, exist\u0103 mul\u021bi factori care sunt studia\u021bi pentru a \u00een\u021belege modul \u00een care microplasticul este ingerat \u0219i c\u00e2t timp este necesar pentru ca efectele sale asupra organismului s\u0103 se manifeste.<\/p>\n\n\n\n

Studiile asupra oamenilor \u00een mod specific au fost limitate, iar aceast\u0103 cercetare a fost adus\u0103 \u00een aten\u021bie, chiar dac\u0103 singurele studii disponibile utilizeaz\u0103 experimente de laborator care expun celulele \u0219i \u021besuturile umane la microplastice sau studii pe animale care implic\u0103 roz\u0103toare.<\/p>\n\n\n\n

Dac\u0103 vorbim despre organisme marine, cel mai evident mod \u00een care plasticul le poate d\u0103una este c\u0103 acestea \u00eenghit mici particule de plastic care nu le ofer\u0103 prea mult\u0103 hran\u0103 pentru a supravie\u021bui. \u00cen cadrul cercet\u0103rii sale, Lynch, care conduce Centrul pentru cercetarea de\u0219eurilor marine<\/a> la Universitatea Hawaii Pacific<\/a> din Honolulu, a examinat materialele plastice \u0219i alte substan\u021be chimice din intestinele broa\u0219telor \u021bestoase de mare g\u0103site moarte pe plaje.<\/p>\n\n\n\n

Echipa ei a efectuat o serie de analize pe nou\u0103 pui de pas\u0103re cu v\u00e2rsta sub trei s\u0103pt\u0103m\u00e2ni \u00een 2020. \u00cen ciuda faptului c\u0103 avea doar 9 centimetri lungime, tractul gastrointestinal al unuia dintre puii de clo\u0219c\u0103 avea 42 de buc\u0103\u021bi de plastic. Majoritatea erau microplastice.<\/p>\n\n\n\n

De\u0219i nu se crede c\u0103 microplasticele sunt principala cauz\u0103 a deceselor, ele r\u0103m\u00e2n o preocupare extrem de important\u0103. \u00cen plus, mul\u021bi oameni de \u0219tiin\u021b\u0103 de renume au f\u0103cut diverse descoperiri legate de microplastice \u0219i de organismele marine.<\/p>\n\n\n\n

Ca o alternativ\u0103 la sfere, oamenii de \u0219tiin\u021b\u0103 folosesc acum fibre sau fragmente de plastic care sunt mai realiste pentru condi\u021biile de mediu. Multe teste de testare sunt acoperite cu substan\u021be chimice care sunt similare cu biofilmele, ceea ce cre\u0219te probabilitatea ca animalele s\u0103 le consume. \u00cen acest fel, a avut loc o schimbare pozitiv\u0103 \u00een ceea ce prive\u0219te recunoa\u0219terea nocivit\u0103\u021bii microplasticelor.<\/p>\n\n\n\n

\u00cen prezent, cercet\u0103torii consider\u0103 c\u0103 microplasticele \u0219i nanoplasticele nu sunt prezente \u00een concentra\u021bii suficiente pentru a afecta s\u0103n\u0103tatea uman\u0103. Cu toate acestea, se a\u0219teapt\u0103 ca num\u0103rul lor s\u0103 creasc\u0103.<\/p>\n\n\n\n

Dac\u0103 trecem la un mod de via\u021b\u0103 sustenabil \u0219i reducem cantitatea de de\u0219euri toxice aruncate \u00een mare, putem \u00eenc\u0103 controla aceast\u0103 problem\u0103.<\/p>\n\n\n\n
