Ukubuka Konke kwe-Bisphenol A BPA
Ekuqaleni yakhiqizwa ngo-1936 njenge-estrogen yokwenziwa, i-bisphenol A (BPA) manje ikhiqizwa ngomthamo waminyaka yonke odlula amakhilogremu ayizigidi eziyizinkulungwane eziyisithupha. I-Bisphenol A BPA isetshenziswa kakhulu njengebhloko yokwakha amapulasitiki e-polycarbonate, atholakala emikhiqizweni efana namabhodlela ezingane, amabhodlela amanzi, ama-epoxy resins (izimbozo ezimboze izitsha zokudla), kanye nama-white dental sealant. Iphinde isetshenziswe njengesengezo kwezinye izinhlobo zamapulasitiki okukhiqiza amathoyizi ezingane.

Ama-molecule e-Bisphenol A BPA akha ama-polymers ngokusebenzisa “ama-ester bond” ukuze adale amapulasitiki e-polycarbonate. Njengengxenye ebalulekile ye-polycarbonate, i-BPA iyikhemikhali eyinhloko kulolu hlobo lwepulasitiki.

I-Bisphenol A – ingxenye eyinhloko ekukhiqizweni kwe-polycarbonate, enikeza amapulasitiki ukucaca okuvelele kanye nokumelana nomthelela. Chofoza lapha ukuze uthole izingcaphuno ezinesaphulelo kanye nezinsizakalo zeqembu ze-Bisphenol A.
