There are many compounds that contain gold that are so deadly, there are
very few people on this list capable of handling them with care. I gather
this from reading months of posts to this and other lists where people want
to play a what-if game of chemical substitution. BE CAREFUL! seek advice
from a chemist, not someone on the Internet.
Even the some of the so called experts who sell chemicals scare me because
of some of the comments they post.
