Dioxane ndi chiyani? Kodi zidachokera kuti?
Dioxane, njira yolondola yolemba ndi Dioxane. Chifukwa zoyipa ndizovuta kwambiri kuti ndi mtundu, munkhaniyi tidzagwiritsa ntchito mawu oyipa m'malo mwake. Ndi chinthu chopangidwa mwamphamvu, chomwe chimadziwikanso kuti Dioxane, 1, 4-dioxane, madzi opanda utoto. Dioxane pachimake mtima ndi poizoni wochepa, ali ndi mankhwala oletsa komanso olimbikitsa. Malinga ndi chilengedwe chazodzikongoletsera zazodzikongoletsera ku China, Dioxane ndi gawo loletsedwa la zodzoladzola. Popeza sizotheka kuwonjezera, bwanji zodzola? Pazifukwa zomwe sizingalephereke, ndizotheka kuti Dioxane ayambitsidwe ndi zodzikongoletsera ngati chidetso. Ndiye zodetsa ziti zomwe zili muzomera?
Chimodzi mwazosagwiritsidwira ntchito zomwe zimagwiritsidwa ntchito kwambiri mu shampoos ndi matumbo matupi amthupi ndi sodium wamafuta mowa ether sulfate aes kapena sles. Gawoli likhoza kupangidwa kuchokera ku mafuta am'madzi kapena mafuta ngati zida zomera, koma zimawonongeka kudzera mu magawo angapo monga ethoxtlation, sulfornation. Gawo lofunikira ndi ethoxtylation, pazinthu izi za momwe zimakhalira, muyenera kugwiritsa ntchito zikwangwani za ethylene oxide Ma molekyulu amangotulutsa chinthu, ndiye kuti, mdani wa dioxane, zomwe zikuchitikazo zitha kuonetsedwa mu chithunzi chotsatira:
Mwambiri, opanga opanga adzakhala ndi njira zambiri zopatukana ndikuyeretsa opanga Dioxane, opanga opanga a Duoxane, opanga mitundu yambiri amagwiritsanso ntchito chizindikiro ichi, nthawi zambiri 20 mpaka 40 mpaka 40ppm. Ponena za muyezo wotsiriza (monga shampu, kutsuka thupi), palibe zizindikiro zapadziko lonse lapansi. Pambuyo pa a Bawang shampoo doko mu 2011, China adakhazikitsa muyezo wa zomalizidwa pazokha pa 30ppm.
Dioxane imayambitsa khansa, imapangitsa nkhawa chitetezo?
Monga zopangira zomwe zimagwiritsidwa ntchito kuyambira pa Nkhondo Yadziko II, sodium sulfate (sles) ndi malo ake opangidwa ndi Dioxane adaphunziridwa kwambiri. United States Chakudya ndi mankhwala osokoneza bongo (FDA) zakhala zikuphunzira za Dioxane pazogulitsa kwa zaka 30, ndipo Canada atha kudziwa kuti kupezeka kwa daoxane pazodzikongoletsera, ngakhale ana (Canada). Malinga ndi ntchito yaku Australia ya ku Australia komanso chitetezo, malire oyenera a dioxane mu zinthu za ogula ndi 30ppm, ndi malire apamwamba a poizoni. Ku China, pambuyo pa 2012, malire a 30ppm for Pulogalamu yodzikongoletsera imakhala yocheperako yovomerezeka kwambiri ya 100ppm munthawi yogwiritsira ntchito bwino.
Komabe, ziyenera kutsimikizika kuti malire a China a Dioxane mu zodzikongoletsera ndi ochepera 30ppm, yomwe ndi muyezo wokhazikika padziko lapansi. Chifukwa, mayiko ambiri ndi zigawo zili ndi malire apamwamba pa dioxane zomwe zili muyezo kapena zomwe sizikuyenda bwino:
M'malo mwake, kufufuza kumakhala kofala mwachilengedwe. Zinthu zoopsa ku US ndi mndandanda wa matenda a dioxane monga kupezeka mu nkhuku, tomato, maluwa komanso ngakhale m'madzi athu akumwa. Ulamuliro wa World Health Organisation ya kumwa madzi abwino (makina achitatu) Fotokozani kuti malire a dioxane m'madzi ndi 50 μg / l.
Chifukwa chake kuti muchepetse vuto la carcinogenic la dioxane mu sentensi imodzi, ndiye kuti: Mosasamala mlingo wolankhula za kuvulaza ndi mtsinjewo.
Wotsika zomwe zili pa Dioxane, abwinoko abwino, eti?
Dioxane si chizindikiritso chokha cha ma sles. Zizindikiro zina monga kuchuluka kwa mankhwala osavomerezeka ndi kuchuluka kwa matenda okwiya omwe ali ndi zogulitsazo ndikofunikanso kulingalira.
Kuphatikiza apo, ndikofunikira kudziwa kuti a Sles amabwera mosiyanasiyana, kusiyana kwakukulu kumakhala kuchuluka kwa ethoxtylation, ena ndi 2, 3 kapena 4 eo (zaka) 1.6 amathanso kupangidwa). Kuchuluka kwa kufalikira, ndiye kuti, kuchuluka kwa eo, komwe kulipo kwa dioxane wopangidwa ndi mawonekedwe ndi kuyeretsa.
Chochititsa chidwi ndichakuti, chifukwa chowonjezera eo ndikuchepetsa kukwiya kwa ma sles, ndi kuchuluka kwa eleckant ya eles, zomwe zili zochepa pakhungu, ndiye kuti, mosemphanitsa. Popanda eo, ndi malo osakondedwa ndi madera, omwe ndi chosasangalatsa kwambiri.
Chifukwa chake, zotsika zotsika za dioxane sizitanthauza kuti zimapezeka chifukwa chaiwisi wabwino. Chifukwa ngati chiwerengero cha Eo ndichaching'ono, kukwiya kwa zinthu zosiyidwa kudzakhala kwakukulu
Powombetsa mkota:
Dioxane si mankhwala owonjezeredwa ndi mabizinesi, koma zopangira zomwe ziyenera kukhalabe m'malo opanda pake monga sles, zomwe ndizovuta kupewa. Osati kokha ma sles okha, malingana ngati ethoxtytion imachitika, padzakhala kuchuluka kwa dioxane, ndipo zida zina zosamalira khungu zimakhalanso ndi DOIOXAINE. Kuchokera pakuwona kwa kuwunika koopsa, monga zotsalira, palibe chifukwa cholowera mwamtheradi 0, tengani ukadaulo wapano, "osawona kuti zomwe zili ndi 0.
Chifukwa chake, kuti mulankhule za kuvulaza kupitilira mlingo ndikuyenera kukhala gangster. Chitetezo cha Daoxane chaphunziridwa kwa zaka zambiri, ndipo miyezo yoyenera komanso yovomerezeka yakhazikitsidwa, ndipo imatsalira osakwana 100ppm amatengedwa kuti ali otetezeka. Koma maiko monga European Union sanakhale muyezo wovomerezeka. Zofunikira zapakhomo pazomwe zili pa dioxane mu malonda ndizochepera 30ppm.
Chifukwa chake, Dioxane mu shampoo sifunika kuda nkhawa za khansa. Ponena za mabodza omwe ali patolankhani, tsopano mukumvetsetsa kuti ndiko kungoyang'ana chidwi.
