Organic Metal Processing Capacity

Organic forms of metals — methylmercury (in large fish), organotin compounds, organic arsenic, organolead — are handled differently from inorganic forms. PON1 (paraoxonase 1) is critical for organophosphate clearance; GSTM1 and GSTT1 contribute to organic compound conjugation. The variant pattern is partly distinct from the inorganic side.

Carriers of common PON1 reduced-activity variants are associated with slower clearance of organophosphate pesticides and certain organic mercury compounds. Carriers of GSTM1-null and GSTT1-null variants are associated with reduced conjugation of organic toxins broadly. Methylmercury, the form most common in fish, can accumulate in nervous tissue specifically.

Selenium-rich foods support PON1 activity and help bind methylmercury. Cruciferous vegetables upregulate Phase II conjugation. Omega-3 fish (smaller, lower-methylmercury species like sardines and wild salmon) deliver the EPA/DHA benefit without the higher methylmercury load of larger predatory species. Organic produce reduces the organophosphate burden meaningfully.

The "I should eat more fish" advice doesn't apply identically to every variant pattern. Which PON1/GSTM1/GSTT1 combination you carry decides which species sit at the top of the rotation, how often, and where organic-produce upgrades earn their cost.
