[Greenbuilding] Toxic Materials in Roof Runoff

It doesn't look like they came to any conclusion regarding roofing material recommendations. But since they collected samples in stainless steel pots, I'm inclined to think stainless steel roofing is the least toxic choice. Anyone agree or disagree?

Washington State Department of Ecology has been doing a pilot study on the
types of toxins that can enter stormwater systems from different types of
roofing materials.  Copper and Zinc are studied pretty carefully, since we
know that the metals contribute to greater mortality in the endangered and
economically important fish in the Pacific NW.

There's a link to it from the roofing pollution topic page
