Scott,
That's pretty cool that you're interested in testing the comments. I've done quite a bit of mass spectrometry on medicine bottle contents, most of which was done when I worked for NWAA on Seattle. I'm out of town, but I can send you the CRM results of the mass spec from 3 different sites.

I can email a picture of the bottle for anyone interested. It was recovered in a trash pit filled with domestic items, in a former residential neighborhood.
