tin cans, could constitute a danger to human life and health, Health
Canada reported last week.
Even the dental industry has cause for concern:"Just when they thought

mercury-based fillings, dentists are finding themselves at the centre

said last week is potentially dangerous and will be banned from use in
plastic baby bottles."
Some studies have found detectable levels of BPA in the saliva of
patients after they received sealants or fillings, but experts are
