On eating fish with mercury, why don’t we have symptoms?

Resolved Question:

Thank you for your answer.
So, If some toxicants get into the cells, that cells are not no more normal.
that means cells would be killed immdiately, or cause sysmtemic toxicity immediately.

T here is one more curious question.
we usually eat fish or other foods which has the mercury,
Almost we are safe and we don't know the symptom, but I think if there is som mercury in food, that toxicant absolutely get into body and stay in neuron or cell or tissue...

If mercury amount is large, we know the bad symptom rightly, but small amount, we could not feel the bad symptom,
Why? becuase we have a lot of cells or neurons, so small amount of cell or neuron death (because of mercury invasion) cannot make people feel symptom?
or no symptom means no mercury invasion?

Pls.. teach me why we cannot know if small amount of mercury get into neuron and cells..
Thanks you very much.

Thank you for your query at
Once the mercury goes inside the cell, it will be dead automatically due to change in physiological processes. If the mercury is very minute in quantity only few cells will die, if it is in significant amount, then it will cause significant damage, say for example, a major portion of neurons will die.
Only when it is in significant amounts , it will enter the cell and cause death and the more number of cells that are involved the more chances of having systemic symptoms.
