Study finds increased toxic mercury levels in tuna and cod

Harvard scientists studied methyl mercury levels in fish from the Gulf of Maine, finding increases in codfish and bluefin tuna over 30 years. Climate change causes larger fish to consume more prey with higher mercury levels. Overfishing has altered the diet of Atlantic cod, leading to higher mercury intake. The study warns of health risks from consuming contaminated fish, linking methyl mercury to neurocognitive issues in children exposed in the womb.
