Ethylene oxideyog ib qho organic compound nrog cov tshuaj mis ntawm C2H4O, uas yog ib qho roj uas yooj yim hlawv. Thaum nws qhov concentration siab heev, nws yuav tso tawm qee qhov saj qab zib.Ethylene oxideyooj yim yaj hauv dej, thiab me ntsis ethylene oxide yuav tsim tawm thaum hlawv luam yeeb. Me ntsis ntawmethylene oxidetuaj yeem pom muaj nyob rau hauv xwm.

Ethylene oxide feem ntau yog siv los ua ethylene glycol, ib yam tshuaj siv los ua antifreeze thiab polyester. Nws kuj tseem siv tau rau hauv tsev kho mob thiab cov chaw tua kab mob kom tua cov khoom siv kho mob thiab cov khoom siv; Nws kuj tseem siv rau kev tua kab mob hauv zaub mov thiab tswj kab tsuag hauv qee cov khoom ua liaj ua teb khaws cia (xws li cov txuj lom thiab tshuaj ntsuab).

Ethylene oxide cuam tshuam li cas rau kev noj qab haus huv

Cov neeg ua haujlwm raug kev cuam tshuam luv luv rau cov tshuaj lom neeg ntauethylene oxidenyob rau hauv huab cua (feem ntau yog kaum txhiab npaug ntawm cov neeg ib txwm) yuav ua rau lub ntsws ua haujlwm. Cov neeg ua haujlwm raug rau cov tshuaj ntau heevethylene oxiderau lub sijhawm luv luv thiab ntev ntev tej zaum yuav raug mob taub hau, tsis nco qab, tsis muaj zog, xeev siab thiab ntuav.

Cov kev tshawb fawb pom tau tias cov poj niam cev xeeb tub raug rau cov tshuaj lom neeg ntau heevethylene oxidenyob rau hauv chaw ua haujlwm yuav ua rau qee tus poj niam poob cev xeeb tub. Lwm txoj kev tshawb fawb pom tsis muaj qhov cuam tshuam zoo li no. Yuav tsum tau tshawb fawb ntxiv kom nkag siab txog kev pheej hmoo ntawm kev raug tshuaj thaum cev xeeb tub.

Muaj tej tsiaj ua paethylene oxidenrog rau qhov muaj ntau heev nyob rau hauv ib puag ncig (ntau dua 10000 npaug ntawm huab cua sab nraum zoov) rau lub sijhawm ntev (hli mus txog xyoo), uas yuav ua rau lub qhov ntswg, qhov ncauj thiab lub ntsws ua haujlwm; Kuj tseem muaj cov teebmeem ntawm lub paj hlwb thiab kev loj hlob, nrog rau cov teeb meem kev yug menyuam ntawm cov txiv neej. Qee cov tsiaj uas nqus tau ethylene oxide rau ob peb lub hlis kuj tau mob raum thiab ntshav tsis txaus (cov qe ntshav liab tsawg dua).

Ethylene oxide yuav ua rau mob qog noj ntshav li cas

Cov neeg ua haujlwm uas raug tshuaj lom ntau tshaj plaws, nrog lub sijhawm nruab nrab raug tshuaj lom ntau tshaj 10 xyoo, muaj feem yuav raug mob qog noj ntshav ntau dua, xws li qee yam qog noj ntshav thiab qog noj ntshav mis. Cov qog noj ntshav zoo sib xws kuj tau pom muaj nyob rau hauv kev tshawb fawb txog tsiaj txhu. Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Pabcuam Tib Neeg (DHHS) tau txiav txim siab tiasethylene oxideyog ib yam kab mob carcinogen uas paub tias ua rau mob qog noj ntshav rau tib neeg. Lub Chaw Tiv Thaiv Ib Puag Ncig ntawm Tebchaws Meskas tau xaus lus tias kev nqus pa ntawm ethylene oxide muaj cov teebmeem carcinogen rau tib neeg.

Yuav ua li cas kom txo tau qhov kev pheej hmoo ntawm kev raug rau ethylene oxide

Cov neeg ua haujlwm yuav tsum hnav tsom iav tiv thaiv, khaub ncaws thiab hnab looj tes thaum siv lossis tsim khoomethylene oxide, thiab hnav cov khoom siv tiv thaiv kev ua pa thaum tsim nyog.
