Latest Bioaccumulation Stories
A Dartmouth-University of Connecticut study of the northeast United States shows that methylmercury concentrations in estuary waters -- not in sediment as commonly thought -- are the best way to predict mercury contamination in the marine food chain.
Rising ocean surface temperatures caused by climate change could make fish accumulate more mercury, increasing the health risk to people who eat seafood.
Microbes that live in rice paddies, northern peat bogs and other previously unexpected environments are among the bacteria that can generate highly toxic methylmercury.
The amount of toxic mercury found in Pacific Ocean fish is expected to increase over the next several decades, claims new research appearing in the August 25 edition of the journal Nature Geoscience.
Scientists are reporting development of a fast, reliable new test that could help people avoid a terrible type of food poisoning that comes from eating fish tainted with a difficult-to-detect toxin from marine algae growing in warm waters.
Feathers collected from the rare Pacific black-footed albatross over the past 120 years have helped researchers from Harvard University track increases in the neurotoxin methylmercury in the endangered bird, which forages extensively throughout the Pacific.
In the first report on the uptake and internal processing of triclocarban (TCC) in fish, scientists today reported strong evidence that TCC â€” an antibacterial ingredient in some soaps and the source of environmental health concerns because of its potential endocrine-disrupting effects â€” has a "strong" tendency to bioaccumulate in fish.
With growing concerns about the effects of global warming on polar bears, it's increasingly important to understand how other environmental threats, such as mercury pollution, are affecting these magnificent Arctic animals.
Belgian scientists say they've found methylmercury, the main form of mercury found in the blood of marine mammals, might do more harm to seals than thought.
U.S. scientists have discovered synthetic carbon molecules called fullerenes, or buckyballs, can accumulated in animal tissue, but break down in sunlight.
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
