Meaning and Definition
An organomercury compound, specifically a toxic organic form of mercury, where a methyl group is bonded to a mercury atom (CH₃Hg⁺).
It is the primary form of mercury that bioaccumulates in aquatic food chains, posing significant health risks to humans and wildlife through the consumption of contaminated fish and shellfish.

FAQ
Frequently Asked Questions
Yes. Thermometer mercury is elemental (metallic) mercury. Methylmercury is an organic compound formed when bacteria react with mercury in water. It is far more toxic and easily absorbed by living organisms.
Large, long-lived predatory fish like shark, swordfish, king mackerel, and some types of tuna (e.g., albacore) tend to have the highest methylmercury levels due to bioaccumulation.
No. Methylmercury is bound tightly to the proteins in fish muscle. Cooking methods (baking, frying) do not significantly reduce methylmercury content.
It primarily affects the nervous system. In adults, symptoms can include impaired vision, speech, and motor coordination. In foetuses and young children, exposure can lead to severe developmental delays and neurological damage.
