Titanium Dioxide's Safety and Supply Issues mu 2017

Titanium dioxide (TiO2) ndi imodzi mwamitundu yovuta kwambiri pamoyo wathu watsiku ndi tsiku. Ndikofunikira kwambiri pazinthu zatsiku ndi tsiku monga mankhwala otsukira mano, zoteteza ku dzuwa, kutafuna chingamu ndi utoto. Zakhala m'nkhani zambiri za 2017, kuyambira ndi mitengo yokwera. Pakhala pali kuphatikiza kwakukulu mu gawo la China la TiO2, zomwe zapangitsa kuti mitengo ikhale yokwera, ndipo China akuti yaletsanso kupanga chifukwa cha nkhawa za mpweya. Moto wa Januware 2017 pafakitale ya Huntsman's TiO2 ku Pori, Finland, udachepetsanso mphamvu ya TiO2 pazaluso zaluso.

Izi zapangitsa opanga inki kulengeza kukwera kwa mitengo pa inki pogwiritsa ntchito titaniyamu dioxide; mwachitsanzo, Siegwerk adatulutsa mawu kumayambiriro kwa Marichi kulengeza mitengo yokwera ya inki zonse zomwe zili ndi titanium dioxide.

Zonsezi ndizovuta mokwanira, koma zovuta zachilengedwe zabwera zomwe zitha kutenga TiO2 kupita kwina, zovuta kwambiri. TiO2 ndi chinthu chofunika kwambiri pakupanga mafuta oteteza ku dzuwa, ndipo pakhala pali nkhawa ku Ulaya pakugwiritsa ntchito nanoparticles mu sunscreen, mankhwala otsukira mano ndi zina zambiri. Chodetsa nkhaŵa, makamaka, chiri pa nanoparticles ya TiO2. Izi zinapangitsa bungwe la European Chemicals Agency (ECHA) kuti lizindikire kuti titanium dioxide ikhoza kukhala carcinogen ngati itakoka mpweya.
Pakhala pali maphunziro ochepa pa kawopsedwe wa titaniyamu woipa.

Posachedwapa, French chakudya chilengedwe ndi Occupational Health and Safety Bureau (Anses) mu pepala, malinga ndi zomwe anapeza, ananena kuti ntchito titaniyamu woipa ngati zotheka chifukwa cha khansa kudzera mpweya wa 1 B-mtundu carcinogens, pempholi adzakhala kuvomerezedwa mwa kalata kapena pambuyo pa gawo la Seputembala.

Nkhani zidafalikira m'makampani. Mabizinesi a Titanium dioxide ali ndi malingaliro. Titaniyamu woipa mu mapeto si carcinogenic zinthu, thanzi la munthu pamapeto palibe angathe kuvulaza?

"Titanium dioxide siwowopsa ndipo ilibe mphamvu pa thanzi la munthu," adatero Shijiang, Wachiwiri kwa Secretary-Gene.ral wa China Coatings Industry Association. ”

Min, general Woyang’anira mafakitale a titaniyamu, anati: “Titanium dioxide ndi zinthu zopanda poizoni, zomwe zakhala zikugwira ntchito m’makampani a titanium dioxide kwa zaka zoposa 10, sanamve chifukwa cha titanium dioxide ndi matenda oyambitsa khansa.” Ngati titaniyamu woipa ndi carcinogenic zotsatira zake zingakhale zazikulu. ”

Kodi titaniyamu dioxide ndi yotetezeka?

Palibe umboni weniweni wosonyeza kuti titaniyamu woipa ndi khansa. Choyamba, zonsezi ndi lingaliro chabe la malo azakudya aku France komanso Occupational Health and Safety Bureau, ndipo ikufunika kufufuza kwina.

Chachiwiri, malo odyetserako chakudya ku France ndi Occupational Health and Safety Administration akungolimbikitsa kuti titaniyamu woipa ngati 1-b carcinogen yomwe ingayambitse khansa pokoka mpweya. Information pa zikalata zogwirizana nthawi zikusonyeza kuti pakhala okhudzana mabungwe mu United States DuPont kampani titaniyamu woipa kupanga chomera 2,477 antchito kuchita kafukufuku wotsatira, zotsatira zikusonyeza kuti kukhudzana mwachindunji ndi titaniyamu woipa sadzakhala kwambiri kuonjezera ogwira ntchito m'mapapo. khansa, matenda aakulu kupuma, pleural zotupa ndi matenda ena okhudzana ndi chiopsezo.

Komanso, zosiyanasiyana zofanana anapeza kuti titaniyamu woipa sachititsa kukhudzana ndi anthu a m'mapapo khansa zochitika mlingo wa kukwera. Deta yochokera ku International Agency for Cancer Research ikuwonetsanso kuti palibe umboni wokwanira wowunika ngati titaniyamu woipa angayambitse khansa mwa anthu. Titanium dioxide imagwiritsidwa ntchito kwambiri popanda cholowa m'malo.
