1, 4-Dioxane yog ib yam kab mob tshwm sim hauv tib neeg thiab tau pom nyob rau hauv dej hauv av ntawm cov chaw thoob plaws Tebchaws Meskas.
Dioxane tuaj yeem pom qhov twg?
Feem ntau, 1, 4-dioxane muaj nyob rau hauv cov khoom uas tsim cov suds, xws li tshuaj zawv plaub hau, kua xab npum thiab ua npuas dejEnvironmental Working Group txoj kev tshuaj xyuas qhia tias 97 feem pua ntawm cov plaub hau so., 57 feem pua ntawm cov xab npum me nyuam thiab 22 feem pua ntawm tag nrho cov khoom hauv Skin Deep tej zaum yuav kis tau 1, 4-dioxane.
1/4-dioxane yog dab tsi?
1, 4-Dioxane tuaj yeem nkag mus rau hauv koj lub cev feem ntau los ntawm kev haus dej tsis huv, ua pa tsis huv lossis vapors, thiab siv cov khoom tsis huv thiab / lossis cov khoom ntxuav.
Dioxane yog dab tsi?
Dioxane yog tsim los ntawm cov kua qaub-catalysed lub cev qhuav dej ntawm diethylene glycol, uas nyob rau hauv lem yog tau los ntawm hydrolysis ntawm ethylene oxide. Xyoo 1985, lub peev xwm tsim tau thoob ntiaj teb rau dioxane yog nyob nruab nrab ntawm 11,000 thiab 14,000 tons. Xyoo 1990, tag nrho US cov khoom ntim ntawm dioxane yog nyob nruab nrab ntawm 5, 250 thiab 9, 150 tons.
Dab tsi yog 1/4-dioxane siv rau hauv tshuaj pleev ib ce?
Nws yog siv los ua cov kuab tshuaj hauv kev tsim khoom ntawm lwm cov tshuaj thiab ua lub chaw kuaj ntshav. Cov kab mob 1, 4-Dioxane yog ib qho kab mob ntawm qee yam tshuaj uas siv hauv tshuaj pleev ib ce, tshuaj ntxuav tes, thiab tshuaj zawv plaub hau.

Ntawm qhov chaw twg tsis pom los ntawm qhov pom sab hauv?
Lub qhov ntswg zoo tshaj plawsyog nyob tom qab thiab yog li tsis pom nyob rau sab xub ntiag. Cov duab 9.1, 9.3, 9.5, 9.7, thiab 9.10 N/A Pab txhawb rau anterior cranial fossa; tsim ib feem ntawm qhov ntswg septum thiab qhov ntswg kab noj hniav;
Nyob rau qhov chaw nyob ze rau qhov pom?
Kev nyob ze ze Lub zeem muag Qhov kev pab cuam reflex (lossis nyob ze teb) yog peb feem reflexuas coj cov khoom ze rau hauv kev tsom los ntawm lens thickening, pupillary constriction, thiab sab hauv kev sib hloov ntawm qhov muag-qhov muag convergence.
Qhov qhov muag tsis pom ntawm lub tsheb thauj khoom nyob qhov twg?
Tsev tsheb ciav hlau qhov muag tsis pom muaj xws li: Ncaj nraim rau pem hauv ntej ntawm lub tsheb thauj khoom mus txog 20 ko taw Ncaj nraim hauv qab lub tsheb thauj khoom li 30 ko taw Txhua sab ntawm lub tsheb thauj mus rau sab nraub qaum Tam sim ntawd hauv qab thiab qab tus neeg tsav tsheb qhov rais Puas muaj qhov muag tsis pom kev tsheb thauj mus los?
Qhov kev pom twg pom kev tsis sib haum xeeb yog qhov tsim nyog?
Thaum tib neeg kev sib raug zoo pom tau txais kev sib haum xeeb ntawm lub koom haum ua ib feem tseem ceeb, kev sib cuam tshuam kev pom ntawm-kev tsis sib haum xeeb ntawm lub koom haum yuav siv tib lub tswv yim ib kauj ruam ntxiv. Nws qhia tias qhov kev tsis sib haum xeeb tsis tu ncua, tsawg kawg yog qhov tsim nyog thiab muaj txiaj ntsig zoo rau ib pab pawg .
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
