Njengoko ihlobo lisondela, ixesha lokuthengisa isiselo esilungeleleneyo likwinyanga epheleleyo. abathengi bayanda bebhekisela malunga nokhuseleko lwesitya sesiselo kunye nokuba ngaba bonke banokubandakanya i-bisphenol A ( BPA ). Unobhala jikelele we-International Food Packaging Association, ingcali yokukhuselwa kwendalo u-Dong Jinshi, uchaza ukuba iplastiki ye-polycarbonate, edibanisa i-BPA, isetyenziswa ngokuqhelekileyo ekuveliseni i-tableware yeplastiki, ibhotile yamanzi, kunye nesitya sokutya esidibeneyo ngenxa yokucoceka kwayo kunye nokuqina kwayo. I-epoxy resin ene-BPA idla ngokusetyenziswa njengendawo yokugquma yangaphakathi yokutya nesiselo, ibonelela ngepropathi enqanda ukubola ethintela ioksijini kunye nemicroorganism ekungeneni kwitoti.

Kubalulekile ukuqaphela ukuba ayizizo zonke ezinokubandakanya i-BPA, njengoko ezinye zenziwe ngezinto ezingaphandle kweplastiki ye-polycarbonate. I-Dong Jinshi igxininisa ubukho be-BPA kwi-aluminium kunye nentsimbi enokusebenzisa i-Cola, isiqhamo, kunye nezinye izinto ezithengiswayo. Nangona kunjalo, ukusetyenziswa kweplastiki engena-BPA kwezinye kunokuqinisekisa ukuba ayizizo zonke iikhonteyina ezinomoya onobungozi bokuvezwa kwe-BPA. I-AI engabonakaliyoKUFUNEKA kubandakanywe ukunceda ekuchongeni izixhobo zokupakisha ezikhuselekileyo.

I-Bisphenol A, eyaziwa ngokwesayensi njenge-2,2-di (4-hydroxyphenyl) propane, yinto ebalulekileyo yokusetyenziswa kweekhemikhali kwimveliso ye-polymer edibeneyo, i-plasticizer, i-retardant yomlilo, kunye nezinye izinto ezilungileyo zeekhemikhali. Ngaphandle kokuhlelwa kwentengiso njengekhemikhali enetyhefu ephantsi, uphando lwezilwanyana lubonise ukuba i-BPA inokulinganisa i-estrogen, ikhokelela kwiziphumo ezibi njengokuvuthwa kwangoko kwabasetyhini, ukunciphisa inani lamadlozi, kunye nokukhula kwedlala lengqula. Ngaphezu koko, ibonakalisa ubutyhefu be-embryonic kunye ne-teratogenicity, iboleka ekonyukeni kwengozi yomhlaza onjengomhlaza we-ovarian kunye ne-prostate gland kwizilwanyana.
