Here's an old EPA PDF from the 70's on neutralization and disposal of Mercury Arsenic Cadmium Chromium.
I had found this because of refining silver contacts.
The pdf size is 8 Mbyte and seems I cannot upload it.
If it can be uploaded to the site it might be an appropriate informational PDF to have here.
