Nano particles may harm living tissue, such as lungs, in at least two ways -- through normal effects of chemical reactivity, or by damaging phagocytes, which are scavenger cells that normally remove foreign substances. Phagocytes can become "overloaded" by nano particles and cease functioning. Worse, overloaded phagocytes retreat into deeper layers and so become unavailable to protect against foreign invaders. Successive particles are then able to do their full reactive damage, and other invaders, such as bacteria, may penetrate unhindered.
This is very scary and is probably happening already all over more so on tge Gulf where nano engineered bacteria etc have been added to the environment!
On a different note I am concerned for OP.He was pretty candid today.I have a feeling that his next mission is going to be dangerous.Let us hope that he and we make it safely through Oct 13th.Hopefully we can all keep this thread alive and vigorous until that time........
