[Paul Viapiano]

I'm not a pigment addict and couldn't tell you a real cad from a fake one, 
and all those PY PR PB numbers or whatever? Well, who knows about all that, 
I certainly don't.

And, yes, cadmium is not a good thing for the environment. That's why it was 
removed from gelatin silver paper and so many other things years ago.

But, like cadmium, potassium and ammonium dichromates are also devastating 
to the environment regardless of who tells you that they are OK or benign. 
So that is why none of it, cadmium or dichromate, goes down my drain. All 
first wash water gets bottled and all brush cleaning water along with it. 
None of this stuff belongs in a public drain, regardless of who tells you 
otherwise.

Don't rely on experts. Experts said offshore underwater drilling was safe, 
too.

Thanks, Judy, for this opportunity to get on my semi-annual soapbox.
