Nchekwa Titanium Dioxide na okwu inye ya na 2017

Titanium dioxide (TiO2) bụ otu n'ime pigmenti kachasị mkpa na ndụ anyị kwa ụbọchị. Ọ dị oke mkpa na ihe ndị a na-eme kwa ụbọchị dịka ntacha eze, mkpuchi anwụ, chịngọm na agba. Ọ nọwo na akụkọ maka ọtụtụ 2017, malite na ọnụ ahịa dị elu. Enweela nkwado dị ukwuu na mpaghara TiO2 nke China, na-eduga ọnụ ahịa dị elu, a kọkwara na China amachibidoro mmepụta n'ihi nchegbu ịdịmma ikuku. Ọkụ nke Jenụwarị 2017 n'ụlọ ọrụ Huntsman's TiO2 dị na Pori, Finland, machiri ikike TiO2 maka nka eserese.

Nke a emeela ka ndị na-emepụta ink kwupụta mmụba ọnụahịa na ink na-eji titanium dioxide; dịka ọmụmaatụ, Siegwerk wepụtara nkwupụta na mbido March na-ekwupụta ọnụ ahịa dị elu maka ink niile nwere titanium dioxide.

Ihe ndị a niile bụ ihe ịma aka zuru oke, mana nsogbu gburugburu ebe obibi abịala ugbu a nke nwere ike iburu TiO2 gaa n'ọkwa ọzọ, siri ike karị. TiO2 bụ isi ihe dị na sunscreens, enweela nchegbu na Europe maka iji nanoparticles na mkpuchi anwụ, ntacha eze na ọtụtụ ihe ndị ọzọ. Nchegbu, karịsịa, bụ n'elu nanoparticles nke TiO2. Nke a mere ka European Chemicals Agency (ECHA) chọpụta na titanium dioxide nwere ike ịbụ carcinogen ma ọ bụrụ na a na-ekuru ya.
Enweela ntakịrị ọmụmụ gbasara nsi nke titanium dioxide.

Na nso nso a, French nri gburugburu ebe obibi na ọrụ Health and Safety Bureau (Anses) na akwụkwọ, dị ka nchoputa ya, tụrụ aro na iji titanium dioxide dị ka ihe nwere ike ịkpata ọrịa cancer site na iku ume nke 1 B-ụdị carcinogens, a amụma ga-abụ. anabatara nke ọma na ederede ma ọ bụ mgbe nnọkọ Septemba gasịrị.

Akụkọ ahụ malitere na ụlọ ọrụ ahụ. Ụlọ ọrụ titanium dioxide nwere echiche. Titanium dioxide na njedebe abụghị ihe carcinogenic, ahụike mmadụ na njedebe ọ nweghị mmerụ ahụ nwere ike ime?

titanium dioxide ọ dị mma?

Enweghị ezigbo ihe akaebe na titanium dioxide bụ carcinogenic. Nke mbụ, ihe niile bụ naanị atụmatụ sitere na gburugburu nri nri France na ngalaba ahụike na nchekwa ọrụ, yana ọ chọrọ nyocha ọzọ.

Nke abụọ, gburugburu nri French na nlekọta ahụike na nchekwa ọrụ na-atụ aro ka etinyere titanium dioxide dị ka carcinogen 1-b nke nwere ike ibute ọrịa kansa site na iku ume. Ozi na akwụkwọ akụkọ ndị dị mkpa na-egosi na e nweela ụlọ ọrụ ndị yiri ya na United States DuPont ụlọ ọrụ titanium dioxide na-emepụta ihe ọkụkụ 2,477 ndị ọrụ na-eme nyocha nyocha, nsonaazụ na-egosi na kọntaktị kpọmkwem na titanium dioxide agaghị eme ka ndị ọrụ nke ngụgụ dịkwuo elu. cancer, ala ala akụkụ okuku ume na ọrịa, pleural ọnya na ọrịa ndị ọzọ metụtara ihe ize ndụ.
