Cercet\u0103torii avertizeaz\u0103 c\u0103 pesticidele, poluan\u021bii, materialele plastice \u0219i substan\u021bele chimice persistente ar putea contribui la o criz\u0103 \u201esilen\u021bioas\u0103\u201d a fertilit\u0103\u021bii, potrivit ScienceAlert<\/a>.<\/p>\n

\u00centr-o nou\u0103 analiz\u0103, o echip\u0103 de toxicologi \u0219i biologi sus\u021bine c\u0103 \u201eo gam\u0103 divers\u0103 de poluan\u021bi, combinat\u0103 cu presiunea cresc\u00e2nd\u0103 exercitat\u0103 de agravarea schimb\u0103rilor climatice\u201d amenin\u021b\u0103 fertilitatea, biodiversitatea \u0219i s\u0103n\u0103tatea la scar\u0103 global\u0103.<\/p>\n

Acest lucru este valabil at\u00e2t pentru oameni, c\u00e2t \u0219i pentru numeroase alte animale, precum mamiferele marine, p\u0103s\u0103rile, pe\u0219tii, nevertebratele \u0219i reptilele.<\/p>\n

\u00cen doar jum\u0103tate de secol, popula\u021biile de animale s\u0103lbatice de pe P\u0103m\u00e2nt au sc\u0103zut cu mai mult de dou\u0103 treimi, iar poluan\u021bii \u0219i schimb\u0103rile climatice sunt considerate cauze semnificative ale acestui declin.<\/p>\n

\u00cen acela\u0219i timp, ratele de infertilitate uman\u0103 par, de asemenea, s\u0103 fie \u00een cre\u0219tere at\u00e2t la b\u0103rba\u021bi, c\u00e2t \u0219i la femei. De\u0219i nimeni nu \u0219tie exact de ce se \u00eent\u00e2mpl\u0103 acest lucru, unii oameni de \u0219tiin\u021b\u0103 au ar\u0103tat cu degetul spre proliferarea substan\u021belor chimice care perturb\u0103 hormonii \u00een vie\u021bile noastre.<\/p>\n

\u00cen prezent, exist\u0103 pe pia\u021b\u0103 peste 1.000 de substan\u021be chimice sintetice care pot imita sau bloca hormonii naturali \u2013 \u0219i acestea sunt doar cele despre care \u0219tim.<\/p>\n

Conform unor estim\u0103ri, doar 1% din toate substan\u021bele chimice sintetice au fost supuse unor evalu\u0103ri de siguran\u021b\u0103 suficiente.<\/p>\n

Substan\u021bele chimice considerate periculoase<\/h2>\n

\u00cen cadrul studiului, cercet\u0103torii au comparat minu\u021bios modul \u00een care rezultatele privind s\u0103n\u0103tatea \u0219i fertilitatea la diverse grupuri de animale erau asociate cu schimb\u0103rile climatice sau cu substan\u021bele chimice sintetice.<\/p>\n

Insecticidele, de exemplu, sunt substan\u021be chimice concepute pentru a ucide insectele care d\u0103uneaz\u0103 culturilor \u0219i s\u0103n\u0103t\u0103\u021bii umane.<\/p>\n

Infamul insecticid DDT este unul dintre pu\u021binele despre care \u0219tim cu certitudine c\u0103 are efecte negative asupra s\u0103n\u0103t\u0103\u021bii \u0219i reproducerii la anumite animale \u0219i la anumite concentra\u021bii.<\/p>\n

Exist\u0103 dovezi c\u0103 DDT a sc\u0103zut ratele de fertilitate \u00een r\u00e2ndul unor mamifere marine, iar aceste rate au crescut constant de c\u00e2nd substan\u021ba chimic\u0103 a fost interzis\u0103 la nivel interna\u021bional.<\/p>\n

\u00cen acela\u0219i timp, substan\u021bele chimice \u201eve\u0219nice\u201d, sau PFAS (substan\u021be per- \u0219i polifluoroalchilice), au fost asociate cu sc\u0103derea ratei fertilit\u0103\u021bii la om, iar unii dintre ace\u0219ti compu\u0219i sunt recunoscu\u021bi ca perturbatori ai sistemului endocrin.<\/p>\n

Acest sistem produce \u0219i distribuie hormoni \u2013 mesageri chimici care contribuie la \u00eendeplinirea unor func\u021bii esen\u021biale \u00een organism, de la cre\u0219tere \u0219i dezvoltare p\u00e2n\u0103 la metabolism \u0219i reproducere.<\/p>\n

Informa\u021biile ascunse de c\u0103tre companii<\/h2>\n

\u00cenc\u0103 din anii 1970, companiile \u0219tiau c\u0103 unii compu\u0219i PFAS erau toxici pentru oameni, dar au ascuns acest lucru de public. Unele angajate \u00eens\u0103rcinate expuse la concentra\u021bii ridicate ale acestor compu\u0219i au suferit avorturi spontane sau au n\u0103scut copii cu malforma\u021bii congenitale. Mai mul\u021bi dintre ace\u0219ti compu\u0219i au fost interzi\u0219i.<\/p>\n

Substan\u021bele chimice care perturb\u0103 sistemul endocrin (EDC) pot persista \u0219i se pot acumula \u00een mediu pentru o perioad\u0103 foarte lung\u0103 de timp. Deoarece sunt at\u00e2t de puternice, este posibil ca, chiar \u0219i la niveluri sc\u0103zute de expunere, acestea s\u0103 aib\u0103 un impact semnificativ asupra organismului animalelor.<\/p>\n

O alt\u0103 poten\u021bial\u0103 catastrof\u0103 planeaz\u0103 asupra impactului microplasticelor asupra s\u0103n\u0103t\u0103\u021bii, acestea put\u00e2nd, de asemenea, perturba sistemul endocrin.<\/p>\n","protected":false},"excerpt":{"rendered":"
