I-Titanium Dioxide's Safety and Supply Izinkinga ngo-2017

I-Titanium dioxide (TiO2) ingenye yemibala ebaluleke kakhulu ekuphileni kwethu kwansuku zonke. Ibalulekile ezintweni zansuku zonke ezifana nokuxubha amazinyo, i-sunscreen, izinsini zokuhlafuna nopende. Ike yaba sematheni cishe unyaka ka-2017, iqala ngamanani aphezulu. Kube nokuhlanganiswa okubalulekile engxenyeni yase-China ye-TiO2, okuholela emananini aphezulu, futhi i-China nayo kubikwa ukuthi ibeke imingcele ukukhiqizwa ngenxa yokukhathazeka ngekhwalithi yomoya. Umlilo wangoJanuwari 2017 embonini ye-Huntsman's TiO2 e-Pori, e-Finland, waphinde wakhawulela umthamo we-TiO2 wobuciko bezithombe.

Lokhu sekuholele ekutheni abakhiqizi be-inki bamemezele ukwenyuka kwentengo kumayinki besebenzisa i-titanium dioxide; isibonelo, uSiegwerk ukhiphe isitatimende ekuqaleni kukaMashi ememezela amanani aphezulu wabo bonke oyinki abane-titanium dioxide.

Konke lokhu kuyinselele ngokwanele, kodwa izinkinga zemvelo manje sezivele ezingase ziyise i-TiO2 kwelinye, izinga elinzima kakhulu. I-TiO2 iyisithako esiyinhloko kuma-sunscreens, futhi kube nokukhathazeka e-Europe mayelana nokusetshenziswa kwe-nanoparticles ku-sunscreen, umuthi wokuxubha nokunye okuningi. Ukukhathazeka, ikakhulukazi, kungaphezu kwama-nanoparticles we-TiO2. Lokhu kuholele ekutheni i-European Chemicals Agency (ECHA) inqume ukuthi i-titanium dioxide ingaba umdlavuza uma ihogelwa.
Kube nezifundo ezilinganiselwe ngobuthi be-titanium dioxide.

Muva nje, i-French food environment and Occupational Health and Safety Bureau (Anses) ephepheni, ngokusho kokutholwe kwayo, iphakamise ukuthi ukusetshenziswa kwe-titanium dioxide njengembangela engenzeka yomdlavuza ngokuhogela i-1 B-type carcinogens, lesi siphakamiso sizoba. yamukelwe ngokusemthethweni ngokubhaliwe noma ngemuva kweseshini kaSepthemba.

Lezi zindaba bezishubile embonini. Amabhizinisi e-Titanium dioxide anombono. I-Titanium dioxide ekugcineni ayiyona into ye-carcinogenic, impilo yomuntu ekugcineni ayikho ingozi engaba khona?

"I-Titanium dioxide ayinawo umdlavuza futhi ayinamthelela empilweni yomuntu," kusho uShijiang, iPhini likaNobhala-Gene.ral we-China Coatings Industry Association. ”

Min, general umphathi wemboni ye-titanium, wathi: “I-Titanium dioxide iwuketshezi olungenabuthi, osekuyiminyaka engaphezu kwengu-10 embonini ye-titanium dioxide, bengezwa ngenxa ye-titanium dioxide nezimo ezibangela umdlavuza.” Uma i-titanium dioxide i-carcinogenic, umphumela ungaba mkhulu. ”

Ingabe i-titanium dioxide iphephile?

Abukho ubufakazi bangempela bokuthi i-titanium dioxide i-carcinogenic. Okokuqala, yonke le nto iyisiphakamiso nje sendawo yokudla yaseFrance kanye ne-Occupational Health and Safety Bureau, futhi idinga ucwaningo olwengeziwe.

Okwesibili, imvelo yokudla yaseFrance kanye ne-Occupational Health and Safety Administration incoma kuphela ukufakwa kwe-titanium dioxide njenge-carcinogen engu-1-b engase ibangele umdlavuza ngokuhogela. Ulwazi mayelana nemibhalo efanele yezikhathi lubonisa ukuthi kuye kwaba nezikhungo ezihlobene e-United States inkampani DuPont ukukhiqiza titanium dioxide plant 2,477 abasebenzi ukwenza ucwaningo lokulandela, imiphumela ibonisa ukuthi ukuthintana ngqo titanium dioxide ngeke kakhulu ukwandisa abasebenzi wamaphaphu. umdlavuza, izifo ezingapheli zokuphefumula, i-pleural izilonda nezinye izifo ezihlobene nobungozi.

Ngaphezu kwalokho, okuhlukahlukene okufanayo okutholakele kubonise ukuthi i-titanium dioxide ayibangeli ukuchayeka kubantu abaningi abanesifo somdlavuza wamaphaphu izinga lokukhuphuka. Idatha evela ku-International Agency for Cancer Research iphinde ikhombise ukuthi abukho ubufakazi obanele bokuhlola ukuthi i-titanium dioxide ingabanga yini umdlavuza kubantu. I-Titanium dioxide isetshenziswa kabanzi ngaphandle kokuthatha indawo.
