4,4′ – DIHYDROXYDIPHENYLMETHANE: Si ballaaran ayaa loo isticmaalaa laakiin khataraha caafimaad ayaa walaac leh

Walax kiimiko ah oo si weyn looga isticmaalo meelo badan oo warshadaha iyo nolol maalmeedka ah ayaa soo jiidanaysa dareenka dadweynaha iyo bulshada sayniska.

I. 4,4′ – DIHYDROXYDIPHENYLMETHANEWaxay leedahay codsiyo kala duwan. Dhinaca warshadaha, 4,4′ – DIHYDROXYDIPHENYLMETHANE waa walax ceeriin ah oo muhiim u ah soo saarista resins epoxy oo waxqabad sare leh. Noocan resin epoxy waxaa si weyn loogu isticmaalaa warshadaha qalabka elektaroonigga ah iyo kuwa korontada. Tusaale ahaan, habka wax soo saarka ee looxyada wareegga daabacan (PCBs), 4,4′ – DIHYDROXYDIPHENYLMETHANE – nooca resins epoxy, oo leh sifooyin koronto, farsamo iyo kulayl oo heer sare ah, waxay hubin karaan hawlgalka xasilloon ee qaybaha elektaroonigga ah ee jawiga shaqada ee adag. Warshadaha dhismaha, agabka ka kooban 4,4′ – DIHYDROXYDIPHENYLMETHANE sidoo kale waxay ciyaaraan door muhiim ah. Waxaa loo isticmaalaa in lagu soo saaro dahaadh iyo dhejis waxqabad sare leh, kuwaas oo bixin kara adkeysi wanaagsan iyo dhejis, taasoo ka dhigaysa qaab-dhismeedka dhismaha mid deggan oo ilaalinaya dibadda dhismaha mid dheer. Intaa waxaa dheer, 4,4′ – DIHYDROXYDIPHENYLMETHANE ayaa sidoo kale ka soo ifbaxaysa warshadaha wax soo saarka ee heerka sare ah sida soo saarista baabuurta iyo hawada sare. Tusaale ahaan, ilaalinta dahaarka qaybaha baabuurta iyo isku xidhka qaab-dhismeedka qalabka hawada sare, 4,4′ – DIHYDROXYDIPHENYLMETHANE ayaa gacan ka geysatay horumarinta waxqabadka badeecada.

II. Khataraha caafimaadku waxay kiciyaan walaac. Si kastaba ha ahaatee, marka cilmi-baaristu sii qoto dheeraato, khataraha caafimaad ee suurtagalka ah ee 4,4′ – DIHYDROXYDIPHENYLMETHANE ayaa bilaabay inay kiciyaan feejignaanta dadka. Tiro daraasado cilmiyeed ah ayaa muujiyay in 4,4′ – DIHYDROXYDIPHENYLMETHANE ay yeelan karaan sifooyinka endocrine - oo carqaladeeya sifooyinka la mid ah 4,4′ – DIHYDROXYDIPHENYLMETHANE (BPA). Waxyaabaha khalkhal geliya endocrine-ka ayaa faragelin kara nidaamka endocrine-ka aadanaha waxayna saameyn karaan dheecaanka caadiga ah iyo shaqooyinka sharciyeynta ee hoormoonnada. Tijaabooyin xayawaan ah qaarkood ayaa muujiyay in xayawaanka tijaabada ah ee la kulmay deegaanka 4,4′ – DIHYDROXYDIPHENYLMETHANE ay yeelan karaan horumar aan caadi ahayn oo ku yimaada nidaamka taranka, cillad qanjirka thyroid-ka iyo ifafaale kale. In kasta oo aan hadda jirin caddayn toos ah oo dhammaystiran oo ku saabsan aadanaha, marka la eego walaacyada caafimaad ee ay mar keeneen 4,4′ – DIHYDROXYDIPHENYLMETHANE iyo isku ekaanshaha qaab-dhismeedka kiimikada ee 4,4′ – DIHYDROXYDIPHENYLMETHANE iyo 4,4′ – DIHYDROXYDIPHENYLMETHANE, khatartan suurtagalka ah lama dhayalsan karo.

III. Kormeerka iyo ka hortagga. Marka la eego khataraha caafimaad ee suurtagalka ah ee 4,4′DIHYDROXYDIPHENYLMETHANE, qaar ka mid ah waddamada iyo gobollada ayaa bilaabay inay nidaamiyaan. Waaxaha khuseeya ayaa dejinaya heerarka deegaanka ee adag iyo heerarka badbaadada badeecadaha si loo xaddido isticmaalka 4,4′ – DIHYDROXYDIPHENYLMETHANE ee qaar ka mid ah alaabada laga yaabo inay si dhow ula xiriiraan jirka aadanaha. Dhanka ganacsiga, qaar ka mid ah shirkadaha kiimikada iyo shirkadaha codsiyada hoose ayaa sidoo kale si firfircoon u sahaminaya beddelka 4,4′ – DIHYDROXYDIPHENYLMETHANE, gaar ahaan meelaha leh shuruudaha badbaadada aadka u sarreeya sida baakadaha cuntada iyo alaabada carruurta. Shaqaalaha R & D waxay ku dadaalayaan inay helaan agab cusub oo buuxin kara shuruudaha waxqabadka badeecada iyagoo hubinaya inay saaxiibtinimo la leeyihiin caafimaadka aadanaha iyo deegaanka. 4,4′ – DIHYDROXYDIPHENYLMETHANE waxay door muhiim ah ka ciyaartaa horumarinta warshadaha, laakiin khataraha caafimaadkeeda waa in si dhab ah loo qaataa. Iyadoo si joogto ah loo sii xoojinayo cilmi-baarista sayniska iyo horumarinta tartiib tartiib ah ee tallaabooyinka sharciyeynta, waxaa la rajeynayaa in iyadoo la siinayo faa'iidooyinkeeda, in la yareeyo waxyeelada suurtagalka ah ee caafimaadka aadanaha iyo deegaanka.
