Methylmercury

Methylmercury is a toxic form of mercury that forms in water when mercury from pollution interacts with microorganisms. It easily accumulates in fish and seafood, especially large, predatory species. When people eat contaminated seafood, methylmercury can build up in their bodies, potentially harming the nervous system, particularly in developing fetuses and young children. It’s important to monitor fish consumption and follow health advisories to reduce exposure, as methylmercury is a persistent and potent neurotoxin that can affect brain function and development.
