Chii chinonzi ethylene oxide?
Ethylene oxideis an organic compound ine kemikari formula C2H4O, inove carcinogen ine muchetura uye yaimboshandiswa kugadzira fungicides. Ethylene oxide inopfuta uye inoputika, uye haisi nyore kutakura nekufamba madaro marefu, saka ine hunhu hwakasimba hwedunhu. Inoshandiswa zvakanyanya mukuwacha, mishonga, kudhinda uye dhayi maindasitiri. Inogona kushandiswa seyekutanga mumiriri wekuchenesa vamiririri mumaindasitiri ane chekuita nemakemikari.
Musi waGumiguru 27, 2017, rondedzero yecarcinogens yakaburitswa neInternational Agency for Research on Cancer yeWorld Health Organisation yakatanga kuunganidzwa kuti itariswe, uye ethylene oxide yakaverengerwa mune rondedzero yeClass 1 carcinogens.
2. Ethylene oxide inokuvadza muviri wemunhu here?
Zvinokuvadza,ethylene oxideimvura isina ruvara inopenya patembiricha yakaderera, inowanzochengetwa mumasilinda esimbi, mabhodhoro asingapindire aruminiyamu kana mabhodhoro egirazi, uye inhaviro yegesi. Iyo ine gasi rakasimba rinopinza simba uye yakasimba bactericidal kugona, uye ine yakanaka kuuraya mhedzisiro pabhakitiriya, mavhairasi uye fungi. Iyo haikonzeri kukanganisa kwezvinhu zvakawanda uye inogona kushandiswa kupfutidza fumigation yemvere, dehwe, midziyo yekurapa, nezvimwewo. Iyo steam ichapisa kana kuputika kana yaiswa pamoto wakavhurika. Inoita ngura pakufema uye inogona kukonzera gastrointestinal kuita sekurutsa, kusvotwa, uye manyoka. Kukuvadzwa kwechiropa uye itsvo uye hemolysis inogonawo kuitika. Kunyanya ganda kusangana ne ethylene oxide mhinduro kunokonzera kupisa kurwadziwa, uye kunyange mablister uye dermatitis. Kugara kwenguva refu kunogona kukonzera cancer. Ethylene oxide chinhu chine muchetura zvakanyanya muhupenyu hwedu. Patinoshandisa ethylene oxide mukuuraya utachiona, tinofanira kunge takashongedzerwa nemidziyo yekudzivirira. Tinofanira kungwarira kuchengeteka uye kuishandisa chete kana mamwe mamiriro ezvinhu asangana.
3. Chii chinoitika kana ethylene oxide ikadyiwa?
Riniethylene oxideinotsva, inotanga kusangana neoxygen kuti ibudise carbon dioxide nemvura. Maitiro equation ndeaya anotevera: C2H4O + 3O2 -> 2CO2 + 2H2O Panyaya yekupisa kwakazara, zvigadzirwa zvinopisa zve ethylene oxide zvinongori kabhoni dhayokisaidhi nemvura. Iyi inzira ine hushamwari hwekupisa moto. Zvisinei, munyaya yekupisa kusina kukwana, carbon monoxide inoumbwawo. Carbon monoxide igasi risina ruvara, risinganhuwi uye rine muchetura zvakanyanya kumuviri wemunhu. Kana kabhoni monoxide ichipinda mumuviri wemunhu, inobatana nehemoglobin kuderedza okisijeni iri muropa, zvichitungamira kuchepfu uye kunyange kufa.
4. Chii chinonzi ethylene oxide mune zvigadzirwa zvemazuva ese?
Patembiricha yemumba, ethylene oxide igasi rinopfuta, risina ruvara nekunhuhwirira kwakanaka. Inonyanya kushandiswa mukugadzirwa kwemamwe makemikari, kusanganisira antifreeze. Zvishoma zveethylene oxide zvinoshandiswa semishonga yezvipembenene nemishonga. Kugona kwe ethylene oxide kukuvadza DNA kunoita kuti ive bhakitiriya ine simba, asi inogonawo kutsanangura kuita kwayo carcinogenic.
Ethylene oxide musanganiswa unosiyana-siyana unoshandiswa mukugadzirwa kwezvimwe zvigadzirwa zvemakemikari zvinoshandiswa mumhando dzakasiyana dzemaindasitiri uye zvigadzirwa zvemazuva ese zvevatengi, zvinosanganisira zvekuchenesa imba, zvigadzirwa zvekuchengeta munhu, uye machira nemachira. Kushandiswa kudiki asi kwakakosha kwe ethylene oxide kuri mukuuraya utachiona hwemidziyo yekurapa. Ethylene oxide inogona kuchenesa midziyo yekurapa uye kubatsira kudzivirira zvirwere nehutachiona.
5. Ndezvipi zvekudya zvine ethylene oxide?
Munyika yangu, kushandiswa kwe ethylene oxide yekudya disinfection kusanganisira ice cream kunorambidzwa zvachose.
Kuti izvi zviitike, nyika yangu yakagadzirawo "GB31604.27-2016 National Food Safety Standard yeKutemerwa kweEthylene Oxide uye Propylene Oxide muPlastiki yeChikafu Kubata Zvishandiso uye Zvigadzirwa" kudzora zvirimo ethylene oxide mukutakura zvinhu. Kana izvo zvinhu zvikasangana nechiyero ichi, hapana chikonzero chekunetseka nezve chikafu chiri kusvibiswa ne ethylene oxide.
6. Chipatara chinoshandisa ethylene oxide here?
Ethylene oxide, inonzi ETO, igasi risina ruvara rinogumbura maziso evanhu, ganda uye nzira yekufema. Muzvikamu zvakaderera, icarcinogenic, mutagenic, kubereka uye nervous system inokuvadza. Kunhuwa kwe ethylene oxide hakuoneki pazasi 700ppm. Naizvozvo, ethylene oxide detector inodiwa kuti itarise kwenguva yakareba yekusangana kwayo kudzivirira kukuvadza kumuviri wemunhu. Kunyangwe iyo yekutanga kushandiswa kwe ethylene oxide iri seyakagadzirwa kune akawanda organic synthesis, kumwe kushanda kukuru kuri mukuuraya hutachiona hwezviridzwa muzvipatara. Ethylene oxide inoshandiswa se sterilizer yeutsi uye inodziya zvinhu. Iye zvino inoshandiswa zvakanyanya mukuita zvishoma kuvhiya maitiro. Kunyange zvazvo dzimwe nzira dzeETO, dzakadai se peracetic acid uye hydrogen peroxide plasma gasi, dzichiramba dzichinetsa, kushanda kwayo uye kushanda kwayo kune zvishoma. Naizvozvo, panguva ino, ETO sterilization inoramba iri nzira yesarudzo.
