Quote from Ullmann's Encyclopedia
Ullmann's is a solid secondary and technical source, without an apparent agenda.
"2.1.9. Toxicology Titanium dioxide is ... regarded as completely nontoxic. .... animals ... fed TiO2 over a long period give no indication of titanium uptake.... Absorption of finely divided TiO2 pigments in the lungs does not have any carcinogenic effect" --Smokefoot (talk) 15:01, 16 September 2017 (UTC)
Production
