Njengoba kusondela ihlobo, isizini yokuthengisa isiphuzo esinhlobonhlobo isisemoyeni ogcwele. umthengi ngokuya ngokuya ekhuluma mayelana nokuphepha kwesiqukathi sesiphuzo nokuthi ingabe bonke bangakwazi yini ukufaka i-bisphenol A ( BPA ). Unobhala jikelele we-International Food Packaging Association, uchwepheshe wezokuvikela imvelo u-Dong Jinshi, uchaza ukuthi ipulasitiki ye-polycarbonate, ehlanganisa i-BPA, ivame ukusetshenziswa ekukhiqizeni i-tableware yepulasitiki, ibhodlela lamanzi, kanye neziqukathi zokudla ezixubile ngenxa yesici sayo esihlanzekile nesiqinile futhi esiqinile. I-epoxy resin ene-BPA ivamise ukusetshenziswa njengesiqukathi esingaphakathi esitsheni sokudla nesiphuzo, ihlinzeka ngempahla evimbela ukugqwala evimbela umoya-mpilo kanye nama-microorganisms ukuthi angangeni ethini.

Kubalulekile ukuqaphela ukuthi akubona bonke abangafaka i-BPA, njengoba abanye benziwe ngezinto ezingaphandle kwepulasitiki ye-polycarbonate. U-Dong Jinshi ugcizelela ubukhona be-BPA ku-aluminium nensimbi engasetshenziselwa i-Cola, i-can fruit, nokunye okuthengiswayo. Nokho, ukusetshenziswa kwepulasitiki engena-BPA kokunye kungaqinisekisa ukuthi akuzona zonke iziqukathi ezibeka ingozi yokuchayeka kwe-BPA. I-AI engabonakaliKUMELE kufakwe ukusiza ukuhlonza izinto zokupakisha eziphephile.

I-Bisphenol A, ngokwesayensi eyaziwa ngokuthi i-2,2-di (4-hydroxyphenyl) propane, iwukusetshenziswa kwamakhemikhali emvelo okubalulekile ekukhiqizeni i-assorted polymer material, i-plasticizer, iretardant, nezinye izinto ezithengiswayo zamakhemikhali. Naphezu kokuthi isikhangiso sichazwa njengekhemikhali enobuthi obuphansi, inhlolovo yezilwane ibonise ukuthi i-BPA ingalingisa i-estrogen, iholele emiphumeleni emibi njengokuvuthwa kwabesifazane abasebasha, ukuncipha kwesibalo sesidoda, nokukhula kwendlala yesinye. Ngaphezu kwalokho, ikhombisa ubuthi be-embryonic kanye ne-teratogenicity, iboleka ekwandeni kwengozi yomdlavuza njengomdlavuza we-ovarian kanye ne-prostate gland ezilwaneni.
