Thank you for your query at DoctorSpring.com
I appreciate your interest in this topic.
However see if it can get inside the cell, by competing with receptors or whatever, it will mostly end up killing the cells. ( mercury comepting with selenium, killing the neurons ).
If it can't do that it will be biotransformed either by liver, or keep causing systemic toxicity.
It will affect the organs directly.
Only staying in cell is not possible, because once it goes inside it will change the physiological functions of the cells. Whenever other leucocytes realise the cell is not normal, the cell will be killed immediately.
