  The body is working with organic molecules more easily. You can literally drink mercury and chew iron and nothing bad will happen (you can, but you shouldn't) - you will pass it the next day. We humans cannot absorb non organic molecules easily. A starving person won't be able to eat charcoal. The mercury vapors are dangerous because you breathe them in which is easy. Organic compound with mercury can be absorbed trough the digestive tract - and mercury inside the blood stream is big problem.
