The primary pathway for human mercury poisoning is consumption of fish that absorb high concentrations of methylmercury through the marine food chain. Landings of tuna and other large predatory fish ...

Many species of fish — several of which end up on our plates — are displaying increasing levels of methylmercury, a very toxic substance. Why is this happening? Researchers from Harvard University ...

Microbes that live in rice paddies, northern peat bogs and other previously unexpected environments are among the bacteria that can generate highly toxic methylmercury, researchers have learned.

While volcanoes and forest fires release mercury, they are relatively small sources compared to the combustion of coal, oil, and other fuels. Mercury is toxic. Microbes turn mercury into a neurotoxin ...

As pollution continues to impact the world’s oceans, methylmercury—the most toxic form of mercury—is increasingly accumulating in global fisheries. As a result, seafood consumption is the primary ...

Methylmercury can accumulate in water environments and enter the food chain. Human exposure is of particular concern in communities affected by contaminated rivers, industrial pollution, artisanal ...

When the Muskrat Falls reservoir is flooded next month, people who harvest food from Lake Melville will have to make a decision. Should they keep the same eating habits they've always had, and risk ...

People who eat fish regularly may ingest low doses of organic mercury, which are toxic metal contaminants found in aquatic environments. Toxicologists have long known that mercury compounds can ...

Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury. That is shown in a new study ...

A 47-year-old California woman has been in a semi-comatose state for weeks after using a Ponds-labeled skin cream tainted with methylmercury. Subscribe to read this story ad-free Get unlimited access ...
