K'hemik'hale e sebelisoang haholo mafapheng a mangata a indasteri le bophelong ba letsatsi le letsatsi e hohela tlhokomelo e eketsehileng ho tsoa ho sechaba le sechabeng sa mahlale.
I. 4,4′ – DIHYDROXYDIPHENYLMETHANEe na le mefuta e mengata ea lits'ebetso. Lefapheng la indasteri, 4,4′ – DIHYDROXYDIPHENYLMETHANE ke thepa ea bohlokoa bakeng sa ho etsa li-resin tsa epoxy tse sebetsang hantle haholo. Mofuta ona oa resin ea epoxy o sebelisoa haholo indastering ea lisebelisoa tsa elektroniki le tsa lisebelisoa tsa motlakase. Mohlala, ts'ebetsong ea tlhahiso ea liboto tsa potoloho tse hatisitsoeng (li-PCB), li-resin tsa epoxy tsa mofuta oa 4,4′ – DIHYDROXYDIPHENYLMETHANE, tse nang le thepa ea tsona e ntle ea motlakase, ea mechini le e hanelang mocheso, li ka netefatsa ts'ebetso e tsitsitseng ea likarolo tsa elektroniki libakeng tse rarahaneng tsa mosebetsi. Indastering ea kaho, thepa e nang le 4,4′ – DIHYDROXYDIPHENYLMETHANE le eona e bapala karolo ea bohlokoa. Li sebelisoa ho hlahisa liphahlo le likhomaretsi tse sebetsang hantle haholo, tse ka fanang ka ho tšoarella hantle le ho khomarela, ho etsa hore sebopeho sa moaho se tsitse haholoanyane le tšireletso ea bokantle ba moaho e tšoarelle nako e telele. Ho feta moo, 4,4′ – DIHYDROXYDIPHENYLMETHANE le eona e hlaha indastering ea tlhahiso ea maemo a holimo joalo ka tlhahiso ea likoloi le lifofane. Mohlala, tshireletsong ya ho kwahela dikarolo tsa dikoloi le ho tlamahana ha sebopeho sa disebediswa tsa sefofane, 4,4′ – DIHYDROXYDIPHENYLMETHANE e kentse letsoho ntlafatsong ya tshebetso ya sehlahiswa.
II. Likotsi tsa bophelo bo botle li baka matšoenyeho. Leha ho le joalo, ha lipatlisiso li ntse li teba, likotsi tse ka bang teng tsa bophelo bo botle tsa 4,4′ – DIHYDROXYDIPHENYLMETHANE li qalile ho tsosa tlhokomelo ea batho. Lithuto tse 'maloa tsa saense li bontšitse hore 4,4′ – DIHYDROXYDIPHENYLMETHANE e ka ba le endocrine – e sitisang thepa e tšoanang le 4,4′ – DIHYDROXYDIPHENYLMETHANE (BPA). Litšitiso tsa endocrine li ka sitisa tsamaiso ea endocrine ea motho 'me tsa ama tlhahiso e tloaelehileng le mesebetsi ea taolo ea lihormone. Liteko tse ling tsa liphoofolo li bontšitse hore liphoofolo tsa liteko tse pepesehetseng tikoloho ea 4,4′ – DIHYDROXYDIPHENYLMETHANE li ka ba le nts'etsopele e sa tloaelehang ea tsamaiso ea ho ikatisa, ho se sebetse hantle ha thyroid le liketsahalo tse ling. Leha hona jwale ho se na bopaki bo tobileng bo tiileng ho batho, ka lebaka la matshwenyeho a bophelo bo botle a kileng a bakwa ke 4,4′ – DIHYDROXYDIPHENYLMETHANE le ho tshwana ha dibopeho tsa dikhemikhale tsa 4,4′ – DIHYDROXYDIPHENYLMETHANE le 4,4′ – DIHYDROXYDIPHENYLMETHANE, kotsi ena e ka bang teng e ke ke ya nyenyefatswa.
III. Tlhokomelo le mehato ea ho thibela. Ka lebaka la likotsi tse ka bang teng bophelong ba 4,4′DIHYDROXYDIPHENYLMETHANE, linaha le libaka tse ling li qalile ho e laola. Mafapha a amehang a ntse a theha maemo a thata a tikoloho le maemo a polokeho ea lihlahisoa ho fokotsa tšebeliso ea 4,4′ – DIHYDROXYDIPHENYLMETHANE lihlahisoa tse ling tse ka bang haufi le 'mele oa motho. Ka lehlakoreng la khoebo, likhoebo tse ling tsa lik'hemik'hale le likhoebo tse sebelisang lik'hemik'hale tse ka tlase le tsona li ntse li hlahloba ka mafolofolo mekhoa e meng ea ho nka sebaka sa 4,4′ – DIHYDROXYDIPHENYLMETHANE, haholo-holo masimong a nang le litlhoko tse phahameng haholo tsa polokeho joalo ka liphutheloana tsa lijo le lihlahisoa tsa bana. Basebetsi ba R & D ba loanela ho fumana lisebelisoa tse ncha tse ka fihlelang litlhoko tsa ts'ebetso ea sehlahisoa ha ba ntse ba netefatsa hore li mosa ho bophelo bo botle ba batho le tikoloho. 4,4′ – DIHYDROXYDIPHENYLMETHANE e bapala karolo ea bohlokoa nts'etsopele ea indasteri, empa likotsi tsa eona tsa bophelo bo botle li lokela ho nkoa ka botebo. Ka ho teba ho sa khaotseng ha dipatlisiso tsa mahlale le ntlafatso e ntseng e tswela pele ya mehato ya taolo, ho tshepilwe hore le hoja melemo ya yona e ntse e bapala, kotsi e ka bang teng bophelong ba batho le tikolohong e ka fokotswa.
