Ulwazi Oluyisisekelo lwe-Bisphenol A (bpa)
I-Bisphenol A, eyaziwa nangokuthi i-BPA, iyinhlanganisela yezinto eziphilayo enefomula yama-molecule C₁₅H₁₆O₂. Kwezimboni, isetshenziswa ekukhiqizeni izinto ezifana ne-polycarbonate (PC) kanye nama-epoxy resins. Kusukela ngawo-1960, i-BPA ibilokhu isetshenziswa ekukhiqizeni amabhodlela epulasitiki ezingane, izinkomishi eziphuzayo, kanye nokwembozwa kwangaphakathi kwamathini okudla neziphuzo (kufaka phakathi ifomula yezingane). I-BPA itholakala yonke indawo—ingatholakala emikhiqizweni eyahlukahlukene, kusukela emabhodleleni amanzi namadivayisi ezokwelapha kuya ezingxeni zangaphakathi zokupakishwa kokudla. Emhlabeni jikelele, kukhiqizwa amathani ayizigidi ezingu-27 epulasitiki aqukethe i-BPA minyaka yonke.

I-Bisphenol A, eqinisekisiwe ngobumsulwa obuphezulu, inikeza ukusebenza okuhle kakhulu kwemikhiqizo engezansi. Chofoza lapha ukuze uthole isilinganiso esinesaphulelo.
