Namhlanje, omnye wabaxumi bethu ufuna i-BPA yasimahla kwizicoci zethu zemoto eziyi-12V, sixakiwe kancinci kule mfuno.Emva kokukhangela kwi-intanethi.sifunde okuninzi ngale nto.Okulandelayo ngumxholo ovela kwi-wiki.
I-Bisphenol A (BPA) yi-organic synthetic compound kunye ne-chemical formula (CH3) 2C (C6H4OH) 2 ephuma kwiqela le-diphenylmethane derivatives kunye ne-bisphenols, kunye namaqela amabini e-hydroxyphenyl.Sisiqina esingenambala esinyibilikayo kwizinyibilikisi zendalo, kodwa asinyibiliki kakuhle emanzini.Sele isetyenziselwa urhwebo ukusukela ngo-1957.
I-BPA iqeshelwe ukwenza iiplastiki ezithile kunye ne-epoxy resins.Iplastiki esekwe kwi-BPA icacile kwaye iqinile, kwaye yenziwe kwiintlobo ngeentlobo zempahla eqhelekileyo yabathengi, njengeebhotile zamanzi, izixhobo zemidlalo, iiCD, kunye neeDVD.Iintlaka ze-epoxy eziqulethe i-BPA zisetyenziselwa ukujongisa imibhobho yamanzi, njengezogqumethelo ngaphakathi kwitoti ezininzi zokutya neziselo kunye nokwenza amaphepha ashushu njengalawo asetyenziswa kwiirisithi zentengiso.[2]Ngo-2015, kuqikelelwa ukuba i-4 yezigidi zeetoni zeekhemikhali ze-BPA zaveliswa ukwenza iplastiki ye-polycarbonate, iyenza ibe yenye yezona zinto ziphezulu zeekhemikhali eziveliswa kwihlabathi jikelele.
I-BPA ibonisa ukulinganisa i-estrogen, iipropathi ezifana nehomoni eziphakamisa inkxalabo malunga nokufaneleka kwayo kwezinye iimveliso zabathengi kunye nezitya zokutya.Ukususela ngo-2008, oorhulumente abaninzi baye baphanda ukhuseleko lwayo, nto leyo eyabangela ukuba abanye abathengisi bahoxise iimveliso ze-polycarbonate.I-US Food and Drug Administration (FDA) iphelile ukugunyaziswa kwayo kokusetyenziswa kwe-BPA kwiibhotile zeentsana kunye nokupakishwa kwefomula yeentsana, ngokusekelwe ekulahlekeni kweemarike, kungekhona ukhuseleko.I-European Union kunye neCanada ziye zavala ukusetyenziswa kwe-BPA kwiibhotile zabantwana.
I-FDA ithi "i-BPA ikhuselekile kumanqanaba akhoyo akhoyo ekutyeni" ngokusekelwe kuphando olubanzi, kubandakanywa nezifundo ezimbini ezikhutshwe yi-arhente ekuqaleni kwe-2014.I-TheEuropean Food Safety Authority (EFSA) ihlolisise ulwazi olutsha lwesayensi kwi-BPA kwi-2008, i-2009, i-2010, i-2011 kunye ne-2015: iingcali ze-EFSA zagqiba ngexesha ngalinye ukuba azikwazi ukuchonga nabuphi na ubungqina obutsha obuya kubakhokelela ukuba bahlaziye uluvo lwabo lokuba inqanaba elaziwayo. ukuvezwa kwi-BPA kukhuselekile;nangona kunjalo, i-EFSA iyakuqonda ukungaqiniseki, kwaye iya kuqhubeka ukuyiphanda.[6]
NgoFebruwari 2016, iFransi yabhengeza ukuba inenjongo yokuphakamisa i-BPA njenge-REACH Regulation umviwa into exhalabisa kakhulu (SVHC).[7]
