What substance poses a health risk to humans who eat large quantities of marine fish such as swordfish and tuna acting as a neurotoxin? what is a major source of this neurotoxin?

Methylmercury

Mercury deposits in sea fishes.

Explanation:

Methylmercury is the source of organic mecury in living organisms which bioaggegated and biomagnified in living organisms.

It toxicity is determined by the PEAK VALUE OF MERCURY consumed in the fish matter.

Comsuption of high Methylmercury, intiated autoimmune response;which

leads to degradation of myelin s3heath of axons in nurones and therefore distrupted nervous transmission of the CNS.

This leads to birth defects in new born.

In adults it causes numbless and tingling of the skin, and followed by coma and death.

It highest concentrations are found in fishes that live longer than others.These fishes have more bio aggregation and biomagnification than others for the quantity of Methylmercury, and therfore high proportion of the compoud when these fishes are consumed

hi!

i'm not sure what the question is, but this statement is true.

hope this fam!
