[Nhcoll-l] Arsenic testing

[Kirsten Nicholson]

So we have done some fairly extensive testing in our collection and had the
same results. Generally this happened where arsenic prepared specimens were
in contact with "clean" specimens" and from the literature I am understand
that there can be cross contamination. So if possible, you want to
quarantine your arsenic specimens away from clean specimens if possible
(there are a number of ways to accomplish this).

I would love to hear what others have to offer, though.
