Kedu ihe bụ ethylene oxide?
Ethylene oxidebụ ngwakọta organic nwere usoro kemịkalụ C2H4O, nke bụ carcinogen na-egbu egbu nke ejiribu mee ihe fungicides. Ethylene oxide na-ere ọkụ ma na-agbawa agbawa, ọ dịghịkwa mfe ibufe ebe dị anya, ya mere o nwere àgwà mpaghara siri ike. A na-eji ya eme ihe n'ọtụtụ ebe n'ịsacha, ọgwụ ọgwụ, mbipụta na ụlọ ọrụ ịcha akwa. Enwere ike iji ya dị ka ihe mmalite maka ndị na-ehicha ihe na ụlọ ọrụ ndị metụtara kemịkal.
N'October 27, 2017, ndepụta nke carcinogens nke International Agency for Research on Cancer of the World Health Organisation chịkọtara na mbụ maka ntụnyere, na ethylene oxide etinyere na ndepụta nke carcinogens Class 1.
2. Ethylene oxide ọ na-emerụ ahụ mmadụ?
Na-emerụ ahụ,ethylene oxidebụ mmiri mmiri na-enweghị agba na-enweghị atụ na obere okpomọkụ, a na-echekwakarị na cylinders ígwè, karama aluminom na-eguzogide nrụgide ma ọ bụ karama iko, na ọ bụ gas sterilizer. Ọ nwere ike ịbanye gas siri ike na ikike nje bacteria siri ike, ma nwee mmetụta igbu egbu dị mma na nje bacteria, nje na fungi. Ọ naghị emebi ọtụtụ ihe, a pụkwara iji ya mee ihe maka fumigation nke ajị anụ, akpụkpọ anụ, ngwá ọrụ ahụike, wdg. Uzuoku ahụ ga-ere ọkụ ma ọ bụ ọbụna gbawara mgbe ọkụ na-emeghe. Ọ na-emebi traktị iku ume ma nwee ike ịkpata mmeghachi omume eriri afọ dị ka vomiting, ọgbụgbọ, na afọ ọsịsa. Imeju na akụrụ arụrụ ọrụ yana hemolysis nwekwara ike ime.

3. Gịnị na-eme ma ọ bụrụ na ethylene oxide na-eri?
Mgbe oleethylene oxidena-ere ọkụ, ọ na-ebu ụzọ meghachi omume na oxygen iji mepụta carbon dioxide na mmiri. Nkwekọrịta mmeghachi omume bụ nke a: C2H4O + 3O2 -> 2CO2 + 2H2O N'ihe gbasara ọkụ ọkụ zuru oke, ngwaahịa combustion nke ethylene oxide bụ naanị carbon dioxide na mmiri. Nke a bụ usoro mgba ọkụ na-adịghị mma na gburugburu ebe obibi. Otú ọ dị, n'ihe gbasara ọkụ ọkụ ezughị ezu, a na-emepụtakwa carbon monoxide. Carbon monoxide bụ gas na-enweghị isi, nke na-egbu egbu nke ukwuu n'ahụ mmadụ. Mgbe carbon monoxide na-abanye n'ime ahụ mmadụ, ọ ga-ejikọta ya na hemoglobin iji belata ikuku oxygen n'ime ọbara, na-eduga n'igbu na ọbụna ọnwụ.
4. Gịnị bụ ethylene oxide na ngwaahịa kwa ụbọchị?
N'ebe okpomọkụ dị n'ime ụlọ, ethylene oxide bụ gas na-ere ọkụ, nke na-enweghị ụcha nke na-esi ísì ụtọ. A na-ejikarị ya emepụta kemịkalụ ndị ọzọ, gụnyere antifirizi. A na-eji obere ethylene oxide mee ihe dị ka ọgwụ na-egbu egbu na ọgwụ nje. Ikike nke ethylene oxide imebi DNA na-eme ka ọ bụrụ nje bacteria dị ike, ma ọ pụkwara ịkọwa ọrụ carcinogenic ya.
Ethylene oxide bụ ngwakọta dị iche iche nke a na-eji na-emepụta ngwaahịa kemịkalụ ndị ọzọ a na-eji na ngwa ụlọ ọrụ dị iche iche na ngwaahịa ndị na-azụ ahịa kwa ụbọchị, gụnyere ndị na-ehicha ụlọ, ngwaahịa nlekọta onwe onye, na akwa na akwa. Obere ma dị mkpa iji ethylene oxide dị na mkpochapụ nke akụrụngwa ọgwụ. Ethylene oxide nwere ike igba ogwu ngwa ngwa ma nyere aka gbochie ọrịa na ọrịa.
5. Kedu nri nwere ethylene oxide?
Na obodo m, a machibidoro iji ethylene oxide maka mkpochapụ nri gụnyere ice cream.
N'ihi nke a, obodo m ewepụtala nke ọma "GB31604.27-2016 National Food Safety Standard for Determination of Ethylene Oxide and Propylene Oxide in Plastics of Food Contact Materials and Products" iji hazie ọdịnaya nke ethylene oxide na nkwakọ ngwaahịa. Ọ bụrụ na ihe ahụ ruru ọkọlọtọ a, ọ dịghị mkpa ichegbu onwe gị maka nri ethylene oxide na-emerụ ya.
6. Ụlọ ọgwụ ọ na-eji ethylene oxide?
Ethylene oxide, nke a na-akpọ ETO, bụ gas na-enweghị agba nke na-akpasu anya, akpụkpọ ahụ na akụkụ iku ume mmadụ. Na obere mkpokọta, ọ bụ carcinogenic, mutagenic, ịmụ nwa na sistem ụjọ. Isi nke ethylene oxide bụ ihe a na-apụghị ịhụ anya n'okpuru 700ppm. Ya mere, a chọrọ onye na-achọpụta ethylene oxide maka nlekota ogologo oge nke ntinye ya iji gbochie mmerụ ahụ na ahụ mmadụ. Ọ bụ ezie na ngwa mbụ nke ethylene oxide bụ ihe eji eme ihe maka ọtụtụ njikọ organic, ngwa ọzọ bụ isi bụ na nsị nke ngwá ọrụ n'ụlọ ọgwụ. A na-eji Ethylene oxide dị ka sterilizer maka uzuoku na ihe ndị na-ekpo ọkụ. A na-eji ya eme ihe ugbu a na usoro ịwa ahụ dị ntakịrị. Ọ bụ ezie na ndị ọzọ na ETO, dị ka peracetic acid na hydrogen peroxide gas plasma, nọgidere na-enwe nsogbu, ịdị irè na ntinye ha nwere oke. Ya mere, n'oge a, ETO sterilization ka bụ usoro nhọrọ.
