I-Bisphenol A: izingozi eziqinisekisiwe kwabesifazane abakhulelwe kanye nezingane zabo
I-ANSES ikhiphe ngoLwesibili ngo-Ephreli 9 imiphumela yocwaningo lwayo ngezingozi ze-bisphenol A empilweni yomuntu futhi iqinisekisa imiphumela eyingozi yombungu wokuchayeka njalo kukanina.
U-ANSES ube nentshisekelo odabeni iminyaka emi-3. Ukulandela umbiko wawo wokuqala, umthetho wamukelwa ngo-2012 wokunciphisa ukusetshenziswa kwe-bisphenol A. Lolu cwaningo olusha luqinisekisa imiphumela yalo yokuqala futhi luyicacise.
Izikhathi ezibucayi kakhulu zokuchayeka zenzeka ku-fetus, neonatal, ukuthomba kanye nokuguga (izifundo zizofika kulesi sikhathi sokugcina). Kowesifazane okhulelwe, ingozi empeleni ihlobene nokungcoliswa kombungu wakhe. Iyini imiphumela? I-BPA idala “ingozi yokuguqulwa kwamangqamuzana endlala yebele okungaholela ekukhuleni kwesimila. kamuva ”kuchaza uMongameli we-ANSES. Ngaphezu kwalokho, imiphumela iye yabonwa ebuchosheni, ekuziphatheni, ohlelweni lokuzala wesifazane olusengozini yokungazali, i-metabolism kanye nokukhuluphala. Ngenkathi i-BPA itholwa kumarisidi okuthengisa ngo-2010, i-ANSES yayiqinisekisa. Manje usebuyekeza isikhundla sakhe, echaza ukuthi ukuchayeka isikhathi eside “kuyisimo esiyingozi, ikakhulukazi endaweni yobungcweti”. Kulolu cwaningo, kwahlaziywa amarisidi angama-50. Okungu-2 kuphela kwakungenayo i-bisphenol A noma i-S. I-BPA ayiqoqi emzimbeni: iyaqhubeka, ukuchayeka okuqhubekayo okubangela ukungcola. Ngakho-ke, i-ANSES ifuna kwenziwe ucwaningo lwe-biometrology phakathi kosokheshi abakhulelwe ngokushesha ngangokunokwenzeka, ukuze kuqinisekiswe imiphumela yalo futhi kumiswe izinyathelo okufanele zithathwe.
Imizila yokungcola
I-Bisphenol A emabhodleleni ezingane ngo-2010, kwase kuba ngamarisidi athengisiwe ngo-2012 ... I-ANSES, ngokokuqala ngqa, inemininingwane yokuchayeka kwangempela kwesibalo sabantu kulo mthombo wobuthi. Ngakho izindlela ezintathu ziye zaqashelwa:
Umzila wokudla uwumthombo oyinhloko wokungcola. Kwahlaziywa amasampula okudla ayi-1162 kanye namasampula amanzi angama-336. Amathini abangela u-50% walokhu kungcola kokudla. Ngempela, ingaphakathi labo le-epoxy resin coating liqukethe i-bisphenol A, ebese ithuthela ekudleni. I-10 kuya ku-15% yezilwane zasolwandle nazo zingaba umthombo wokungcola futhi phakathi kuka-25 kuya ku-30% wokudla kunokungcola okungaziwa ukuthi umsuka wayo uvelaphi. Mayelana nabesifazane abakhulelwe, kungenxa yokumuncwa ukudla okungcolile (umthombo oyinhloko wokuchayeka ku-84%), lapho i-BPA inqamula i-placenta futhi ifinyelele ku-fetus.. Ngaphandle kokuthi abacwaningi bakwazi ukunquma ukuthi i-BPA ihlala ku-amniotic fluid.
Umzila we-cutaneous : umzimba ungcoliswe ukukhohliswa okulula kwezinto eziqukethe i-bisphenol. I-BPA isetshenziswa ekwenzeni i-polycarbonate (ipulasitiki eqinile, esobala futhi egaywa kabusha), ezitsheni eziningi noma ekunyatheliseni okushisayo (amarisidi okuthengisa, amarisidi asebhange). Umzila wesikhumba uqondile futhi uyingozi kakhulu. I-BPA ingena ngqo emzimbeni, ngokungafani nomzila wokudla okuthi, ngokugaya, ube nezihlungi eziningi. "Ucwaningo nge-INRS luzokwenziwa ngale ndaba" kucacisa umqondisi we-ANSES, ukuze uqonde kangcono imiphumela yokumuncwa esikhumbeni. Kwabesifazane abakhulelwe, ukuphatha njalo izinto eziqukethe i-bisphenol A kuyisimo esiyingozi, njengoba into enobuthi ingena emzimbeni ngokuqondile ngesikhumba. Ngakho-ke ukukhathazeka okuqondile mayelana nosokheshi abakhulelwe abaphatha amathikithi aqukethe i-Bisphenol nsuku zonke.
Umgudu wokuphefumula, ngokuhogela izinhlayiya ezingcolile nothuli oluqukethwe emoyeni ozungezile.
Ezinye izindlela ze-bisphenol
Ezinye izindlela ezingama-73 zitholwe abacwaningi “ngaphandle koyedwa okwazi ukufaka esikhundleni sakho konke ukusetshenziswa kwe-bisphenol ngendlela yendawo yonke”, icacisa umqondisi we-ANSES. Abacwaningi abanalo idatha yokuhlola ubungozi besikhathi eside kubantu abavezwe kulezi zindlela ezihlukile zomthamo ophansi. Lokhu kungadinga ukwenziwa kocwaningo isikhathi eside. Kodwa-ke, kucatshangelwa i-ANSES, “asikwazi ukulinda umphumela walolu hlobo lokufunda ukuze senze”.
