Hi Doug, I have pondered this same question many times. Radioactive waste keeps coming to mind! Seriously, though, an internet search suggests that toxic heavy metals have been widely used - there is growing awareness of this issue and beginning attempts to use safer alternatives in the dyes.
Some many years ago, I worked for a chemical company that specialized in reselling dyes. I can attest to the fact that there is some really nasty stuff in those dyes, some of which is heavy metals. Nasty nasty stuff indeed.
