Yes Karin,
This is quite true. However, a blood test, once or twice a year and good studio hygiene is more than sufficient to handle the problem. As well as proper disposal of rags/paper or solvent.
I am speaking of tubed Flake White, by the way.
W and N also has a Flake White replacement seen in their Winton Series. I have used the W and N and the Gamblin replacement, but I still prefer the Zn0/Ti02 mix I hand mull in walnut oil with a very little stand oil added. The replacements were too translucent and left me a litte nervous about see through.
If you need to understand toxicity in pigments, tubed or dried, ask the druggist for his copy of the Pharmacopoeia (Martin Dale on my side). You may be interested in Cobalt and Manganese (umber and sienna).
