redOrbit Staff & Wire Reports - Your Universe Online A decade after first advising pregnant and breast-feeding women to avoid most types of seafood, the US Food and Drug Administration (FDA) is now encouraging those individuals to eat more fish – provided it is low in mercury. The FDA, in collaboration with the Environmental Protection Agency (EPA) issued a new set of guidelines Tuesday encouraging pregnant and breast-feeding women, as well as those who might become pregnant and...

WASHINGTON, June 10, 2014 /PRNewswire-USNewswire/ -- Today, FDA and EPA issued draft updated advice on fish consumption. While the draft is improved in several ways, the Mercury Policy Project was most disappointed with the agencies failure to require labeling and address exposure risks from American's consumption of canned tuna. "Over one-third of American's exposure to methlymercury is from tuna, because tuna are higher mercury fish and Americans consume so much," said Michael...

NEW YORK, Feb. 20, 2014 /PRNewswire-USNewswire/ -- Fluoride joins lead, arsenic, methylmercury, toluene, tetrachloroethylene, and other chemicals known to cause harm to brains, reports the Fluoride Action Network (FAN). Fluoride is newly classified as a developmental neurotoxin by medical authorities in the March 2014 journal Lancet Neurology. The authors are Dr. Philippe Grandjean of the Harvard School of Public Health and Dr. Philip Landrigan of the Icahn School of Medicine. The...

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. The findings raise questions about current mercury cleanup practices, and shed new light on the different ways in which the toxic metal bioaccumulates in aquatic species, from bottom-dwelling worms to forage fish to larger fish consumed by...

Mercury In Arctic Russian Rivers On The Decline
2013-12-21 05:37:36

April Flowers for redOrbit.com - Your Universe Online Researchers have assumed for years that high and increasing levels of mercury in the North American and European Arctic means the same is true of fish elsewhere in the Arctic. A team of researchers from the US, Russia, and Canada, however, has discovered that in much of the continental Arctic, that assumption is misguided. Differences in mercury processes occur because of diverse atmospheric, geological, and biological conditions....

New Low-cost, Nonhazardous Way To Cut Risks From Mercury Hot Spots
2013-10-25 10:59:23

Smithsonian Hot spots of mercury pollution in aquatic sediments and soils can contaminate local food webs and threaten ecosystems, but cleaning them up can be expensive and destructive. Researchers from the Smithsonian Environmental Research Center and University of Maryland, Baltimore County have found a new low-cost, nonhazardous way to reduce the risk of exposure: using charcoal to trap it in the soil. Mercury-contaminated "Superfund sites" contain some of the highest levels of...

Dartmouth, other researchers report global warming may boost fishes' metabolism and accumulation of toxic metal Rising ocean surface temperatures caused by climate change could make fish accumulate more mercury, increasing the health risk to people who eat seafood, Dartmouth researchers and their colleagues report in a study in the journal PLOS ONE. Until now, little has been known about how global warming may affect mercury bioaccumulation in marine life, and no previous study has...

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 at Oak Ridge National Laboratory and the Smithsonian Environmental Research Center have learned. This finding, published in Environmental Science and Technology, explains why deadly methylated mercury is produced in areas where the neurotoxin’s presence has puzzled researchers for decades. Methylmercury —...

Mercury (element) Mercury, also called quicksilver, is a chemical element in the periodic table that has the symbol Hg (from the Greek hydrargyrum, for watery (or liquid) silver) and atomic number 80. A heavy, silvery, transition metal, mercury is one of only two elements that are liquid at room temperature (the other is bromine). Mercury is used in thermometers, barometers and other scientific apparatuses. Mercury is mostly obtained by reduction from the mineral cinnabar. Notable...
