I-ethylene oxideiyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali ye-C2H4O, okuyigesi evuthayo yokwenziwa. Uma ukuhlushwa kwayo kuphezulu kakhulu, izokhipha ukunambitheka okumnandi.I-ethylene oxideincibilika kalula emanzini, futhi inani elincane le-ethylene oxide lizokhiqizwa uma kushiswa ugwayi. Inani elincane le-i-ethylene oxidekungatholakala emvelweni.

I-ethylene oxide isetshenziswa kakhulu ekwenzeni i-ethylene glycol, ikhemikhali esetshenziselwa ukwenza i-antifreeze kanye ne-polyester. Ingasetshenziswa nasezibhedlela nasezindaweni zokubulala amagciwane ukubulala amagciwane imishini yezokwelapha kanye nezinto ezidingekayo; Iphinde isetshenziselwe ukubulala amagciwane ekudleni kanye nokulawula izinambuzane emikhiqizweni ethile yezolimo egciniwe (njengezinongo namakhambi).

Indlela i-ethylene oxide ethinta ngayo impilo

Ukuchayeka kwesikhashana kwabasebenzi ekugxileni okuphezulu kwe-i-ethylene oxideemoyeni (ngokuvamile izikhathi ezingamashumi ezinkulungwane kunezabantu abavamile) kuzovuselela amaphaphu. Izisebenzi ezivezwe ekugxilweni okuphezulu kwe-i-ethylene oxideisikhathi esifushane nesinde singase sibe nesifo sekhanda, ukulahlekelwa yinkumbulo, ukungakhululeki, isicanucanu nokuhlanza.

Ucwaningo luthole ukuthi abesifazane abakhulelwe babhekene nokwanda okukhulu kwe-i-ethylene oxideemsebenzini kuzokwenza abanye besifazane baphuphunyelwe yisisu. Olunye ucwaningo alutholanga mphumela onjalo. Kudingeka ucwaningo olwengeziwe ukuze kuqondwe izingozi zokuchayeka ngesikhathi sokukhulelwa.

Ezinye izilwane ziphefumulai-ethylene oxideenokugxila okuphezulu kakhulu endaweni ezungezile (okuphindwe izikhathi eziyi-10000 kunomoya ojwayelekile wangaphandle) isikhathi eside (izinyanga kuya eminyakeni), okuzovuselela ikhala, umlomo namaphaphu; Kukhona nemiphumela yezinzwa neyokukhula, kanye nezinkinga zokuzala zabesilisa. Ezinye izilwane ezaphefumula i-ethylene oxide izinyanga eziningana nazo zaba nesifo sezinso kanye ne-anemia (ukwehla kwenani lamaseli abomvu egazi).

Kungenzeka kangakanani ukuthi i-ethylene oxide ibangele umdlavuza

Izisebenzi ezichayeke kakhulu, ezinesikhathi esimaphakathi sokuchayeka esingaphezu kweminyaka eyi-10, zisengozini enkulu yokuhlushwa izinhlobo ezithile zomdlavuza, njengomdlavuza wegazi kanye nomdlavuza webele. Umdlavuza ofanayo utholakale nasocwaningweni lwezilwane. UMnyango Wezempilo Nezinsizakalo Zabantu (i-DHHS) unqume ukuthii-ethylene oxideiyisifo somdlavuza esaziwayo kubantu. I-US Environmental Protection Agency iphethe ngokuthi ukuhogela i-ethylene oxide kunemiphumela ebangela umdlavuza kubantu.

Indlela yokunciphisa ingozi yokuchayeka ku-ethylene oxide

Abasebenzi kumele bagqoke izibuko zokuzivikela, izingubo kanye namagilavu ​​​​lapho besebenzisa noma bekhiqizai-ethylene oxide, futhi ugqoke imishini yokuvikela ukuphefumula uma kudingeka.
