Maalgad kiimiko ah oo si ballaadhan loogu isticmaalo qaybo badan oo warshadaha ah iyo nolol maalmeedka ayaa leh dareenka sii kordhaya ee bulshada iyo bulshada cilmiga ah.
I. 4,4 '- DihydroxydiphethethethaneWaxay leedahay codsiyo fara badan oo kala duwan. In warshadaha, 4,4 '- Dihydroxydiphethethethane waa shey ceyriin ah oo wax soo saarka sare loogu sameeyay - dhajinta waxqabadka eproxy-ka ah. Nooca noocan ah ee 'Epoxy Resin' ayaa si weyn loogu isticmaalaa qalabka elektiroonigga ah iyo warshadaha qalabka korantada. Tusaale ahaan, hanaanka wax soo saarka ee guddiyada wareejinta ee daabacan (PCBS), 4,4 '- Dihydroxydiphethethethethethethethemyne - oo ku qoran koronto-dhimis, farsamo-yaqaanno heer sare ah, farsamo-darro, waxay hubin kartaa hawlgalka xasilloonida ee qaybaha shaqada ee adag ee jawiga shaqada ee adag. Warshadaha dhismaha, agabyada ay ku jiraan 4,4 '- Dihydroxydiphethethethane ayaa sidoo kale door muhiim ah ka ciyaara. Waxaa loo isticmaalaa in lagu soo saaro jaakad-sare oo sare iyo adhesies, oo bixin kara cimri dherer wanaagsan iyo is-xakameyn, taasoo ka dhigeysa dhismaha dhismaha inuu xasilloon yahay iyo ilaalinta bannaanka dhismaha muddo dheer - waayaya. Intaas waxaa sii dheer, 4,4 '- Dihydroxydiphethethethethethane ayaa sidoo kale soo ifbaxaya warshadaha soosaarka ee ugu sarreysa sida waxsoosaarka gawaarida iyo aerospace. Tusaale ahaan, ilaalinta daboolka ee qaybaha gawaarida iyo qaab dhismeedka qaabdhismeedka qalabka hawada, 4,4 '- Dihydroxydiphethethethethethane ayaa gacan ka geystay hagaajinta waxqabadka badeecada.
II. Khataraha caafimaadku waxay soo bandhigaan walaacyada. Si kastaba ha noqotee, maadaama loo sii dheereeyo baaritaanka, halista caafimaad ee suurtagalka ah ee 4,4 '- Dihydroxydiphethethethethethethane ayaa bilaabay inuu kiciyo feejignaanta dadka. Dood ka mid ah daraasado saynis saynis ah ayaa muujiyay in 4,4 '- Dihydroxydiphethethethethethane. Qalabka Endocrine ee carqaladeysan kara nidaamka endocrine ee aadanaha oo saameyn ku yeelan kara sirta caadiga ah iyo howlaha caadiga ah ee ham-hoosaadka hormoonnada. Some animal experiments have shown that experimental animals exposed to the 4,4′ – DIHYDROXYDIPHENYLMETHANE environment may have abnormal development of the reproductive system, thyroid dysfunction and other phenomena. Although there is currently no conclusive direct evidence in humans, in view of the health concerns once caused by 4,4′ – DIHYDROXYDIPHENYLMETHANE and the similarity in the chemical structures of 4,4′ – DIHYDROXYDIPHENYLMETHANE and 4,4′ – DIHYDROXYDIPHENYLMETHANE, this potential risk cannot be underestimated.
III. Kormeer iyo ka hortag. Marka loo eego khataraha caafimaad ee suurtagalka ah ee4,4'dihydroxydiphethethethethethane, wadamada qaarkood iyo gobollada ayaa bilaabay inay habeeyaan. Waaxyada ay khusayso ayaa dejinaya heerar aad u adag oo jawi adag oo heerar sare ah oo lagu xadido adeegsiga 4,4 '- Dihydroxydiphethethethethethethethethethethethethemy ee ka mid ah jidhka aadanaha. Dhinaca shirkada, shirkadaha kiimikada qaarkood iyo shirkadaha shirkadaha hoos udhaca ayaa sidoo kale si firfircoon uga baaraandegaya waxyaabaha kale ee lagu beddeli karo 4,4 '- Dihydroxydiphethethethethethethane, gaar ahaan meelaha ay ka mid yihiin baahiyaha nabadgelyada aadka u sarreeya sida baakadaha cuntada iyo alaabada carruurta. Shaqaalaha R & D waxay ku dadaalayaan sidii ay u heli lahaayeen waxyaabo cusub oo buuxin kara shuruudaha waxqabadka badeecada iyadoo la hubinayo inay saaxiibtinimada yihiin caafimaadka aadanaha iyo deegaanka. 4,4 '- Dihydroxydiphethethethethethane ayaa door muhiim ah ka ciyaaraya horumarka warshadaha, laakiin khataraha caafimaad ee caafimaad waa in si dhab ah loo qaataa. Iyada oo ay la socoto qoto dheer ee cilmi-baarista sayniska iyo hagaajinta tartiib-tartiib ee tillaabooyinka sharci-dejinta, waxaa la rajeynayaa in inta la siinayo ubadkooda, waxyeelada suurtagalka ah ee caafimaadka aadanaha iyo jawiga aadanaha waa la yareyn karaa.
