Isu tataura kakawanda pamusoro pema greats Zvakanakira kuyamwisa, kunyanya kubva ku kuyamwa kwenguva refu uye kuyamwisa mwana oga. Zvakawanda zvidzidzo zvakaitwa pane izvi uye, kusvika parizvino, zvese zvakawanikwa zvakanakira. Zvisinei ikozvino ongororo inoti mukaka wemuzamu unotamisa zvinhu zvine chepfu kune vana vanoyamwisa.
Ndisati ndaenderera mberi nekutsanangura mhedziso yechidzidzo ichi, ndinoda kujekesa izvozvo Izvi zvinofungidzirwa kuti zvine huturu hazviiti nekuda kwemukaka pachawo, asi asi nekuda kwehuwandu hwehuturu hwezvigadzirwa uye zvinhu zvatiri kusangana nazvo.. Kubva pakuona kwangu, urwu ruzivo harukutyise zvakanyanya, zvirinani kwete kudarika iro dhata rakawanikwa nekunyatsoongorora huturu hwezvigadzirwa zvakatikomberedza, kutanga nemvura yemupombi. Kana isu tichinyatsoita hanya nezvenyaya iyi, ndinoona zvichinyanya kukosha kufunga nezve huwandu hwezvinowedzera, madhayi uye mafuta ehydrogenated atinodya uye ayo - kazhinji - anokwanisa kusvika kuvana. Asi ngatitaurei nezve chidzidzo. Ramba uchiverenga, nekuti hauna marara.
Tarisa kukwirira kwakanyanya kwevanyoro mumukaka wemvere
Boka revatsvakurudzi vanobva kuYunivhesiti yeBoston, muUnited States, vakaratidza izvozvoe mamwe makemikari makemikari anonzi perfluorinated (PFC), ayo aripo mune zvekugezesa uye zvisina-tsvimbo zvigadzirwa uye anowanzo pinda mumuviri kuburikidza nemvura, anogona zvakare kutapurirwa kubva kuna amai kuenda kuvana kuburikidza nekuyamwa.
Aya maajenzi anowanzo shandiswa mune zvekugezesa, zvinonyungudika, muTeflon indasitiri yemidziyo yekicheni pane velcro uye kunyangwe mune mamwe machira kana makontena. Vakadaro vamiririri, pavanosangana nemvura, vanopedzisira vapinda mukati memuviri zvichikonzera kushanduka mune immune system, yekubereka uye endocrine masystem.
Nekudaro, mhedzisiro yebasa iri yakaburitswa mupepanhau Environmental Sayenzi & Technology, ratidza kuvepo kwePFCs kunowedzera mwedzi wega wega pakati pemakumi maviri kusvika makumi matatu muzana muvana vanoyamwisa.
"Isu tanga tichiziva kuti zvidiki zvePFCs zvinogona kuoneka mumukaka wemukaka, asi kuongororwa kweropa kwakawanda kwatakaita izvozvi kunoratidza kuvakwa kwevacheche mukuyamwisa," anodaro Philippe Grandjean, muongorori paHarvard Chan Chikoro uye mumwe wevanyori vebasa pamwe chete nemayunivhesiti eDenmark neFaroese Hospital System (Faroe Islands).
Kuti vasvike pamhedzisiro iyi, vaongorori vakatevera vana makumi masere nevanomwe vakazvarwa muFaroe Islands pakati pa81 na1997, uye vakaongorora kuvepo kwemhando shanu dzePFC muropa ravo pakuzvarwa uye pazera remwedzi gumi nerimwe, mwedzi gumi nemana uye makore mashanu. . Vakatarisawo mazinga emakomponi aya mumadzimai evana muvhiki yechi2000 yemimba.
Iko kuunganidzwa kwehupfu kunowedzera sezvo kuyamwisa kuchikura
Chidzidzo ichi chinoratidza kuti muvana vakayamwiswa chete, kuwanda kwePFC muropa kwakawedzera pakati pe20 kusvika makumi matatu muzana mwedzi wega wega. Muchiitiko chevacheche-lactation vacheche, izvi zvinongedzo hazvina kuwedzera zvakanyanya.
Masayendisiti anonongedza kuti mune dzimwe nguva, pakupera kwekuyamwisa, huwandu hwevasungwa vePFC muserum yevana hwakapfuura hwaamai vavo. Nekudaro, imwe mhando yekomboni, kunyanya perfluorohexanesulfonic (PFHx), haikure nekuyamwisa.
Kunyangwe mhedziso dzekudzidza dzichiratidza kuti mukaka wemuzamu chinhu chakakosha sosi yekuratidzwa kune izvi zvine chepfu panguva yehucheche, Vatsvagurudzo vanocherekedza kuti kana vakadzi varega kuyamwa, kuwanda kwemhando shanu dzePFC kunoderera muvana.
"Hatisi kukurudzira kuyamwisa, asi isu tiri kunetsekana kuti zvinosvibisa izvi zvinobva kuchizvarwa kuenda kuchizvarwa pazera diki kwazvo," Grandjean anopedzisa.
Isina-chepfu kuyamwisa
Sezvandakakuudza pakutanga, Kuyamwisa chepfu kunokonzerwa nekuratidzwa kune mamwe macomputer anopinda mumukaka wemukaka. Naizvozvo, zvinokwanisika kufunga kuti, kufungidzira, chikafu uye a Mararamiro asina chepfu Izvo zvinogona kugadzirisa kwete chete iri dambudziko remukaka wemukaka, asi mamwe matambudziko mazhinji ehutano.
Kana idzi nhau dzichikuvhundutsa kwauri, inguva yakanaka yekutanga kuongorora zvese zvaunodya uye makemikari aunozviisa pachena kwauri, nekuti dai asiri mumuviri wako angadai asina kupfuudza kumwana wako. Uye usakanganwa kuenderera uchiongorora zvakanaka zvese zvigadzirwa zvaunopa mwana wako, kubva kumvura kusvika kune michero, nyama nehove, kuburikidza nezvigadzirwa zvine shuga yakanatswa uye pasina kukanganwa zviwitsi uye zvigadzirwa zvemaindasitiri nemafuta avo. Hydrogenated.
