Titanium Dioxide muaj kev nyab xeeb hauv cov khoom noj
Cov khoom noj muaj kuab lom thoob ntiaj teb thiab cov khoom noj ntxiv rau cov khoom noj ntxiv uas Titanium Dioxide tuaj yeem siv cov hmoov nplej thiab cov nplej zom, ntawm titanium dioxide hauv cov zaub mov. Tsis muaj kev txwv rau ADI qhov tseem ceeb siv hauv cov txheej txheem. Xyoo 1969, Jecfa. tau ua raws li qhov tseeb tias hauv ntau hom kev kawm, suav nrog tib neeg kev tshawb fawb, Titanium Dioxide tsis pom tias muaj kev nqus thiab txhim tsa. Hauv European Union, Titanium Dioxide (feem ntau yog suav nrog cov khoom noj uas pom zoo xim I ntawm EC 94/36 / kev cai. Titanium Dioxide tsim muaj ob lub tshuab ua lead ua - anatase thiab rutile. Nws tau hais nyob rau hauv cov lus qhia 94/36 / txoj cai / kev cai lij choj uas titanium dioxide tsuas yog tso cai siv hauv daim ntawv anatase.
GB 2760-1996}}}}}} Tseem nrog cov khoom lag luam seem ntawm cov khoom noj xws li cov khoom noj uas titanium dioxide yog ib qho kev nyab xeeb ntxiv ntxiv.
Raws li cov cai sau ua saum toj no thiab kev coj ua, nws txaus los qhia tias titanium dioxide yog kev nyab xeeb, cov zaub mov tsis muaj kev phom sij ntxiv.
