Reac\u021biile la studiul publicat recent de Agen\u021bia Francez\u0103 pentru Siguran\u021ba Alimentelor, Mediului \u0219i S\u0103n\u0103t\u0103\u021bii Ocupa\u021bionale (ANSES) atrag aten\u021bia asupra riscului de dezinformare <\/strong>privind ambalajele reutilizabile \u0219i sigure. Studiul din 20 iunie 2025, publicat sub titlul ini\u021bial \u201eB\u0103uturile din sticle de sticl\u0103 con\u021bin mai multe microplastice dec\u00e2t cele din alte ambalaje\u201d<\/a>, a fost intens mediatizat, \u00eens\u0103 formularea sa a generat confuzie \u0219i interpret\u0103ri eronate.<\/p>\n\n\n\n

Ce a descoperit, de fapt, studiul ANSES?<\/h3>\n\n\n\n

Contaminarea identificat\u0103 \u00een sticlele de sticl\u0103 provine nu de la sticl\u0103<\/strong>, care este un material inert, f\u0103r\u0103 plastic, ci de la capacele sticlelor<\/strong> \u2013 mai exact de la:<\/p>\n\n\n\n

    \n
  • vopselele polimerice<\/strong> aplicate pe capace;<\/li>\n\n\n\n
  • garniturile interioare<\/strong> care asigur\u0103 etan\u0219area, ambele con\u021bin\u00e2nd polimeri sintetici (plastice);<\/li>\n\n\n\n
  • frecare mecanic\u0103<\/strong> \u00een timpul transportului \u0219i depozit\u0103rii.<\/li>\n<\/ul>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    Aceste surse ascunse de microplastice nu sunt vizibile cu ochiul liber \u0219i nu sunt men\u021bionate frecvent \u00een comunicarea public\u0103, ceea ce a dus la concluzii gre\u0219ite. Sub presiunea organiza\u021biilor de mediu, ANSES a fost nevoit\u0103 s\u0103 revizuiasc\u0103 titlul comunicatului de pres\u0103, care acum precizeaz\u0103 corect: \u201eCapacele sticlelor de sticl\u0103 contamineaz\u0103 b\u0103uturile cu microplastice\u201d<\/strong>.<\/p>\n\n\n\n

    Pentru a \u00een\u021belege mai bine fenomenul \u0219i a testa posibile solu\u021bii, cercet\u0103torii au realizat un experiment simplu, dar revelator.<\/strong> Sticlele au fost umplute cu ap\u0103 filtrat\u0103, pentru a elimina orice surs\u0103 extern\u0103 de contaminare, \u0219i au fost \u00eenchise cu capace tratate \u00een mod diferit. \u00centr-un prim caz, capacele nu au fost cur\u0103\u021bate deloc; \u00een al doilea, acestea au fost suflate cu aer comprimat; \u00een al treilea, capacele au fost cur\u0103\u021bate at\u00e2t cu aer, c\u00e2t \u0219i cu ap\u0103 filtrat\u0103 \u0219i alcool. Rezultatele au ar\u0103tat o sc\u0103dere semnificativ\u0103 a nivelului de microplastice \u00een func\u021bie de tratamentul aplicat: de la aproape 300 de particule pe litru \u00een cazul capacelor necur\u0103\u021bate, la mai pu\u021bin de 90 de particule pe litru \u00een cazul celor cur\u0103\u021bate complet.<\/p>\n\n\n\n

    IMPORTANT!<\/mark><\/strong> Aceste rezultate demonstreaz\u0103 c\u0103 sursa contamin\u0103rii nu este sticla \u00een sine, ci componentele adiacente ambalajului \u2013 \u00een special capacele \u0219i vopselele folosite. Este un semnal important pentru industrie, care ar putea adopta m\u0103suri simple de preven\u021bie: <\/mark><\/strong>cur\u0103\u021barea capacelor \u00eenainte de utilizare, \u00eembun\u0103t\u0103\u021birea condi\u021biilor de depozitare pentru a evita frecarea \u00eentre capace \u0219i, mai ales, revizuirea compozi\u021biei vopselelor utilizate, astfel \u00eenc\u00e2t acestea s\u0103 nu mai con\u021bin\u0103 materiale plastice inutile.<\/p>\n\n\n\n

    De ce este aceast\u0103 comunicare problematic\u0103?<\/h3>\n\n\n\n

    Titlul ini\u021bial a comparat tenden\u021bios contaminarea sticlelor de sticl\u0103 cu cea a sticlelor din plastic, f\u0103r\u0103 a reflecta \u00eentregul context \u0219tiin\u021bific:<\/p>\n\n\n\n

      \n
    • Studiile anterioare (inclusiv \u00een SUA, 2024) arat\u0103 c\u0103 apa \u00eembuteliat\u0103 \u00een plastic poate con\u021bine p\u00e2n\u0103 la 240.000 particule de microplastic per litru<\/strong>.<\/li>\n\n\n\n
    • Studiile franceze independente (Agir pour l\u2019environnement, 2024) au identificat zeci de fragmente de plastic<\/strong> \u00een b\u0103uturi ambalate \u00een plastic.<\/li>\n\n\n\n
    • Studiul ANSES nu a analizat particulele sub 30 \u00b5m \u0219i nici nanoplasticele<\/strong>, de\u0219i acestea sunt considerate mai periculoase pentru s\u0103n\u0103tate.<\/li>\n<\/ul>\n\n\n\n

      Compararea cu sticla, f\u0103r\u0103 a lua \u00een calcul aceste aspecte, a creat o imagine distorsionat\u0103 \u0219i \u00een\u0219el\u0103toare, cu poten\u021bial de a submina eforturile actuale de promovare a solu\u021biilor reutilizabile.<\/p>\n\n\n\n

      \u00cen plin proces interna\u021bional de negociere pentru tratatul global \u00eempotriva polu\u0103rii cu plastic, comunicarea \u0219tiin\u021bific\u0103 corect\u0103, responsabil\u0103 \u0219i clar\u0103<\/strong> este mai important\u0103 ca oric\u00e2nd. De aceea, mesajul corect este: Sticla face parte din solu\u021bie, nu din problem\u0103. S\u0103 nu ne l\u0103s\u0103m indu\u0219i \u00een eroare.<\/strong><\/p>\n\n\n\n
