Dab tsi yog ethylene oxide?
Ethylene oxide yog cov organic sib xyaw nrog cov tshuaj c2h4o, uas yog cov tshuaj lom carcinogen thiab yav dhau los siv los ua fungicides. Ethylene oxide yog nplaim taws thiab tawg, thiab tsis yooj yim thauj dhau qhov kev ncua deb, yog li nws muaj cov yam ntxwv muaj zog. Nws yog dav siv hauv kev ntxuav, kws tshuaj paus, luam ntawv thiab cuam tshuam kev lag luam. Nws tuaj yeem siv ua tus neeg sawv cev pib rau cov neeg sawv cev hauv cov tshuaj lom neeg muaj kev lag luam.
Lub Kaum Hlis 27, 2017, cov npe ntawm carcinogens tso tawm los ntawm lub koomhaum thoob ntiaj teb tau xub sau ua ke rau cov npe ntawm chav kawm 1 carcinogens.
2. Puas yog ethylene oxide ua rau muaj kev phom sij rau tib neeg lub cev?
Teeb meem, Ethylene oxide yog lub pob tshab ua kua tsis muaj kob ntawm qhov kub thiab txias, feem ntau khaws cia hauv cov raj hlau, siab-resistan, siab-resistan txhuas hwj lossis iav fwj, thiab yog cov roj ntsha solinter. Nws muaj cov roj khov rau lub zog thiab muaj peev xwm tua tsiaj zoo, thiab muaj kev tua tsiaj zoo rau cov kab mob, kab mob thiab fungi. Nws tsis ua rau puas rau feem ntau cov khoom thiab tuaj yeem siv rau kev fumigation ntawm pluab, tawv, cov khoom siv kho mob, thiab lwm yam yuav hlawv lossis tawg thaum raug qhib. Nws yog corrosive rau cov ua pa ua kom haum thiab tuaj yeem ua rau mob hnyuv tshuaj xws li ntuav, xeev siab, thiab zawv plab. Mob siab thiab raum ua haujlwm ua kev puas tsuaj thiab hemolysis tej zaum kuj tshwm sim. Cov tawv nqaij ntau dhau nrog kev daws teeb meem oxylene yuav ua rau mob mob hlawv, thiab cov hlwv thiab mob dermatitis. Ntev mus ntev yuav ua rau mob cancer. Ethylene oxide yog cov tshuaj lom heev hauv peb lub neej. Thaum peb siv ethylene oxide rau kev tua kab mob, peb yuav tsum tau nruab nrog cov khoom tiv thaiv. Peb yuav tsum xyuam xim rau kev nyab xeeb thiab siv nws tsuas yog thaum qee cov xwm txheej tau ntsib.
3. Yuav muaj dab tsi tshwm sim yog ethylene oxide tab tom noj?
Thaum Ethylene oxide Burns, nws xub rov kho nrog oxygen los tsim cov pa roj carbon dioxide thiab dej. Cov tshuaj tiv thaiv cov tshuaj tiv thaiv muaj raws li nram no: C2h4o + + 2H2O nyob rau hauv rooj plaub, cov khoom sib txuas ntawm ethylene oxide tsuas yog carbon dioxide thiab dej. Qhov no yog ib txoj kev sib txuas ua ke ib puag ncig. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv ntawm kev ua tsis tiav kev sib txuas, carbon monoxide kuj tsim. Cov pa roj carbon monoxide yog cov pa tsis muaj kob, tsw ntxhiab uas muaj tshuaj lom rau tib neeg lub cev. Thaum carbon monoxide nkag mus rau tib neeg lub cev, nws yuav sib txuas nrog hemoglobin kom txo cov txiaj ntsig cov ntshav, ua rau muaj kev lom zem thiab tuag.
4. Dab tsi yog ethylene oxide hauv cov khoom txhua hnub?
Nyob rau hauv chav tsev kub, ethylene oxide yog cov nplaim taws, muaj roj tsis muaj ntxhiab nrog tus ntxhiab tsw qab. Nws yog tsuas yog siv nyob rau hauv kev tsim cov tshuaj lom neeg, nrog rau cov tshuaj tiv thaiv kab mob. Cov roj ntsha me me ntawm ethylene oxide yog siv raws li cov tshuaj tua kab thiab tshuaj tua kab mob. Lub peev xwm ntawm ethylene oxide mus rau DNA puas tsuaj ua rau nws muaj kev sib tw muaj zog, tab sis kuj tseem tuaj yeem piav qhia nws cov kev ua haujlwm carcinogenic.
Ethylene oxide yog ib qho kev sib txuas ntau yam siv nyob rau hauv kev tsim cov khoom siv tshuaj lom uas siv ntau yam kev lag luam tshuaj thiab cov khoom noj txhua hnub, cov khoom lag luam uas tsev neeg, thiab cov ntaub thiab cov ntawv nyeem. Ib qho me me tab sis tseem ceeb siv ethylene oxide yog nyob rau hauv kev tua kab mob ntawm cov khoom siv kho mob. Ethylene oxide tuaj yeem steriled kho cov khoom siv kho mob thiab pab tiv thaiv kab mob thiab kab mob.
5. Cov zaub mov twg muaj ethylene oxide?
Hauv kuv lub teb chaws, kev siv tshuaj ethylene oxide rau kev ua zaub mov noj nrog cov dej khov yog nruj me ntsis.
Txog qhov kawg no, kuv lub teb chaws tseem tau muab cov qauv "GB3160 tshwj xeeb rau kev txiav txim siab ntawm ethylene oxide thiab cov khoom lag luam" los tswj cov ntsiab lus ntawm ethylene oxide hauv cov ntaub ntawv ntim khoom. Yog tias cov ntaub ntawv ua tau raws li tus qauv no, tsis tas yuav txhawj xeeb txog cov zaub mov tsis huv los ntawm ethylene oxide.
6. Lub tsev kho mob puas siv ethylene oxide?
Ethylene oxide, raug xa mus rau ASO, yog cov roj tsis muaj roj uas ua rau tib neeg lub qhov muag, tawv nqaij thiab ua pa. Hauv cov kev ua kom muaj ntau, nws yog carcinogenic, mutagenic, kev ua me nyuam thiab cov paj hlwb ua kom tsis zoo. Cov ntxhiab tsw ntawm ethylene oxide yog imperceptible hauv qab 700ppm. Yog li ntawd, lub ethylene oxide olitect yog qhov yuav tsum tau saib xyuas ntawm nws txoj kev xav kom tiv thaiv kev ua mob rau tib neeg lub cev. Txawm hais tias thawj daim ntawv thov ntawm ethylene oxide yog cov khoom siv raw rau ntau cov synthes organic, lwm daim ntawv thov loj yog nyob rau hauv cov tshuaj tua kab mob hauv tsev kho mob. Ethylene oxide yog siv los ua kev tsis huv rau cov khoom thiab cov khoom siv kub. Tam sim no dav siv nyob rau hauv kev phais mob tsawg kawg. Thaum lwm txoj kev xaiv rau ETO, xws li perigetic acid thiab hydrogen peroxide ntshav, nyob tsis muaj teeb meem, lawv cov txiaj ntsig thiab kev siv tau muaj txiaj ntsig. Yog li no, nyob rau ntawm no taw tes, arto kom tsis muaj menyuam yog txoj kev xaiv.
