Ukuhlolisisa kwe-Bisphenol A BPA
Ekuthomeni yakhiqizwa ngo-1936 njenge-estrogen yokwenziwa, i-bisphenol A (BPA) nje yenziwa ngevolumu edlula ama-6 billion wamaphawundi. I-Bisphenol A BPA isetjenziswa khulu njengesisetjenziswa sokwakha amapulasitiki we-polycarbonate, atholakala emikhiqizweni efana namabhodlela wabantwana, amabhodlela wamanzi, ama-epoxy resins (ama-coating amboza iintjalo zokudla), kanye nama-white dental sealants. Isetjenziswa njengesengezo kezinye iinhlobo zamaplastiki zokwenza amathoyizi wabantwana.

Amamolekhyuli we-Bisphenol A BPA akha ama-polymer ngokusebenzisa "ama-ester bonds" ukwenza amaplastiki we-polycarbonate. Njengengcenye eqakathekileko ye-polycarbonate, i-BPA yinto eqakathekileko yamakhemikhali emhlobeni lo wepulasitiki.

I-Bisphenol A – ingcenye eqakathekileko ekukhiqizeni i-polycarbonate, enikela amaplastiki ukukhanya okuhle khulu nokujamelana nokutjhayisana. Tlika lapha ukuthola iingcaphuno ezihlisiweko kanye namasevisi wethimba we-Bisphenol A.
