I picked up a leaflet at my holistic dentist's office that has information on Sources and Symptoms of Heavy Metal Toxicities. I thought this might be useful concerning sources.

In addition to what Russ included, these are some sources of Possible Mercury Toxicity in Our Environment:

Animal & Industrial Waste
Automobile Exhaust
Pesticides
Fertilizers
Drinking Well Water
Seawater, Seafood
Tanner Leather, Felt
Rainwater, Snow
Mercuric Chloride (histology Labs)
Bleached Flour
Processed Foods
Fabric Softeners
Calomel (Body Powder, Talc)
Skin Lightning Creams
Paint Pigments, Solvents
Hemorrhoid Suppository
Cinnabar (used in jewelry)
Laxatives
Mercurochrome, Merthiolate
Mascara, Cosmetics
External Salves
Floor Wax, Polish
Wood Preservatives
Plumbing, Piping
Air Conditioning Filter
Adhesives
Batteries

And here are some alternative names for Mercury. These can be found in all kinds of products from cleaning products to personal hygiene products.
