O sticl\u0103 de ap\u0103 uitat\u0103 \u00een ma\u0219in\u0103 \u00een timpul unei zile caniculare poate fi expus\u0103 unor temperaturi mult mai ridicate dec\u00e2t cele \u00eenregistrate la exterior. C\u0103ldura \u0219i lumina direct\u0103 a soarelui pot accelera migrarea anumitor substan\u021be din plastic \u00een ap\u0103, iar \u00een cazul sticlelor deja deschise apare \u0219i problema dezvolt\u0103rii bacteriilor.<\/p>\n\n\n\n

Informa\u021biile prezentate de Mediafax<\/a>, pe baza unei analize publicate de Il Post, arat\u0103 \u00eens\u0103 c\u0103 nu exist\u0103 o regul\u0103 potrivit c\u0103reia apa devine automat periculoas\u0103 dup\u0103 un anumit num\u0103r de ore. Temperatura, durata expunerii, tipul recipientului \u0219i pozi\u021bia acestuia \u00een ma\u0219in\u0103 sunt factori importan\u021bi.<\/p>\n\n\n\n

Ce se \u00eent\u00e2mpl\u0103 cu sticla de ap\u0103 \u00eentr-o ma\u0219in\u0103 \u00eencins\u0103<\/h2>\n\n\n\n

Majoritatea sticlelor pentru ap\u0103 sunt realizate din PET, polietilen tereftalat. La temperaturi ridicate, c\u0103ldura poate favoriza migrarea unor substan\u021be folosite \u00een procesul de fabrica\u021bie. Printre cele analizate se num\u0103r\u0103 antimoniul, utilizat drept catalizator la producerea PET.<\/p>\n\n\n\n

Un studiu citat de surs\u0103 a estimat c\u0103 nivelul de antimoniu ar putea dep\u0103\u0219i limita considerat\u0103 sigur\u0103 \u00een SUA dup\u0103 176 de zile la 60\u00b0C, 12 zile la 70\u00b0C \u0219i dou\u0103 zile la 80\u00b0C. Datele nu indic\u0103 faptul c\u0103 apa uitat\u0103 c\u00e2teva ore \u00een automobil devine automat toxic\u0103, ci eviden\u021biaz\u0103 importan\u021ba combina\u021biei dintre temperatur\u0103 \u0219i durata expunerii.<\/p>\n\n\n\n

Soarele poate accelera degradarea plasticului<\/h2>\n\n\n\n

Expunerea direct\u0103 la radia\u021bia solar\u0103 poate favoriza foto-oxidarea PET-ului. Procesul poate contribui la migrarea unor substan\u021be \u0219i la formarea altor compu\u0219i prin degradarea materialului. Pot ap\u0103rea inclusiv microplastice \u0219i nanoplastice, de\u0219i Organiza\u021bia Mondial\u0103 a S\u0103n\u0103t\u0103\u021bii consider\u0103 c\u0103 dovezile disponibile nu permit \u00eenc\u0103 evaluarea cu certitudine a riscului acestora pentru s\u0103n\u0103tate.<\/p>\n\n\n\n

Pozi\u021bia sticlei conteaz\u0103. Un recipient p\u0103strat \u00een portbagaj \u0219i ferit de razele soarelui este expus unor condi\u021bii diferite fa\u021b\u0103 de unul l\u0103sat pe bord. De asemenea, simpla r\u0103cire ulterioar\u0103 a apei nu inverseaz\u0103 migrarea substan\u021belor care s-a produs deja.<\/p>\n\n\n\n

Aten\u021bie mai ales la sticlele din care ai b\u0103ut deja<\/h2>\n\n\n\n

Pentru o sticl\u0103<\/a> desf\u0103cut\u0103 intervine o problem\u0103 suplimentar\u0103. Atunci c\u00e2nd o persoan\u0103 bea direct din recipient, bacteriile din cavitatea bucal\u0103 ajung \u00een ap\u0103, iar temperaturile ridicate pot favoriza multiplicarea acestora.<\/p>\n\n\n\n

Un studiu din 2005, \u00een care apa din sticle folosite a fost p\u0103strat\u0103 timp de 48 de ore la 37\u00b0C, a constatat o cre\u0219tere de peste 40.000 de ori a num\u0103rului coloniilor bacteriene. Asta nu \u00eenseamn\u0103 c\u0103 toate bacteriile identificate erau periculoase, dar rezultatul arat\u0103 de ce p\u0103strarea \u00eendelungat\u0103 la cald a unei sticle deja utilizate nu este recomandat\u0103.<\/p>\n\n\n\n

Frigiderul nu \u201erepar\u0103\u201d apa \u021binut\u0103 la temperaturi extreme<\/h2>\n\n\n\n

Introducerea sticlei \u00een frigider sau congelator nu elimin\u0103 substan\u021bele care au migrat deja din plastic. Nici fierberea nu reprezint\u0103 o metod\u0103 de eliminare a acestora \u0219i poate chiar concentra anumi\u021bi compu\u0219i prin evaporarea unei p\u0103r\u021bi din ap\u0103.<\/p>\n\n\n\n

Pentru \u0219oferi, recomandarea practic\u0103 este simpl\u0103: sticlele din plastic nu ar trebui p\u0103strate perioade lungi \u00eentr-o ma\u0219in\u0103 \u00eencins\u0103 \u0219i mai ales \u00een lumina direct\u0103 a soarelui. Pentru c\u0103l\u0103torii lungi poate fi folosit un recipient reutilizabil, depozitat \u00eentr-o zon\u0103 c\u00e2t mai bine protejat\u0103 de c\u0103ldur\u0103. O sticl\u0103 uitat\u0103 c\u00e2teva ore \u00een automobil nu trebuie privit\u0103 automat drept o surs\u0103 de intoxica\u021bie, \u00eens\u0103 expunerea prelungit\u0103 la temperaturi extreme justific\u0103 pruden\u021b\u0103.<\/p>\n\n\n\n
