Pamene chirimwe chikuyandikira, nyengo yogulitsa zakumwa zamitundumitundu ikuyandikira. ogula akuchulukirachulukira ponena za chitetezo cha chidebe chakumwa komanso ngati onse amatha kuphatikiza bisphenol A (BPA). Mlembi wamkulu wa bungwe la International Food Packaging Association, katswiri woteteza zachilengedwe a Dong Jinshi, akufotokoza kuti pulasitiki ya polycarbonate, yomwe imaphatikizapo BPA, imagwiritsidwa ntchito popanga pulasitiki, botolo la madzi, ndi chidebe cha zakudya zosiyanasiyana chifukwa cha mawonekedwe ake oyera komanso osasunthika komanso okhalitsa. Utoto wa epoxy wokhala ndi BPA umagwiritsidwa ntchito ngati zokutira mkati mwa chidebe cha chakudya ndi chakumwa, kupereka zinthu zoletsa dzimbiri zomwe zimalepheretsa mpweya ndi tizilombo ting'onoting'ono kulowa m'chimbudzi.

Ndikofunika kuzindikira kuti si onse omwe angaphatikizepo BPA, monga ena amapangidwa ndi zinthu zina osati pulasitiki ya polycarbonate. Dong Jinshi amatsindika kukhalapo kwa BPA mu aluminiyamu ndi chitsulo angagwiritsidwe ntchito Cola, akhoza zipatso, ndi malonda ena. Komabe, kugwiritsa ntchito pulasitiki wopanda BPA mwa ena kumatha kutsimikizira kuti si chidebe chonse chomwe chimakhala chowopsa cha BPA. AI yosadziwikaZIKUYENERA kuphatikizirapo kuti zithandizire kuzindikira zida zoyikamo zotetezeka.

Bisphenol A, yomwe imadziwika kuti 2,2-di (4-hydroxyphenyl) propane, ndiyofunikira kwambiri popanga zinthu zosiyanasiyana za polima, plasticizer, retardant fire, ndi zinthu zina zabwino za mankhwala. Ngakhale amatchulidwa kuti ndi mankhwala otsika kawopsedwe, kafukufuku wa nyama awonetsa kuti BPA imatha kutsanzira estrogen, kumabweretsa zotsatira zoyipa monga kukhwima kwa akazi, kuchepa kwa umuna, komanso kukula kwa prostate gland. Kuphatikiza apo, imawonetsa kuopsa kwa embryonic komanso teratogenicity, kubwereketsa kuwopsa kwa khansa monga khansa ya ovarian ndi prostate gland mu nyama.
