titanium dioxyde is considered to be potentially cancerigenous by EEC Health authorities. if outdoor applications can be envisaged, indoor ones (buildings, cars, ...) can be hazardous. does anyone know more about this?

[@ronaldblackwell]

I don't know where EEC Health authorities got there data but here is a link showing all of the products that have titanium dioxide (TiO2) in them. www.chemicalsafetyfacts.org/titanium-dioxide/
