It seems nano-toxicity is also about the ability to cross the blood/brain barrier. If some particles trigger the same toxicity dampening effects that the Alzheimers plaques try to implement, inflammation will continue to damage the brain and it's electrochem interactions. Brain as grey-goo

it also seems like you haven't included prions in your graph. A prion in the wild is a possible template for self replication of another protein, that may have horrid outcomes. It is also pretty simple to see distribution in the food network, perhaps as a food color, as an easy, and accidental distribution method

edit Seems like you haven't read Ringworld, or you would have some worse considerations of a specific carbon cutting organism released to the atmosphere. For instance, what if something was developed that only cut the O-O bond , in particular, that CO2 would get a lot deadlier....

I think that all kinds of nanoparticles are appearing naturally in the form of smoke and dust. It is known to be unhealthy, but nothing like existential risk. Smoking cigarets is known to damage brain, but it is not a grey goo.

I included prions in another my map biological risks, here: http://lesswrong.com/r/discussion/lw/nbw/the_map_of_global_catastrophic_risks_connected/
