ADHD Behaviors Linked To Prenatal Mercury Exposure
2012-10-09 08:37:20

April Flowers for redOrbit.com - Your Universe Online Globally, about ten percent of children have attention deficit hyperactivity disorder (ADHD). Its causes, however, are not very well understood. A new study, published online in the Archives of Pediatrics & Adolescent Medicine, has made a link between low-level prenatal mercury exposure with a greater risk of ADHD-related behaviors. Additionally, the study found that maternal fish consumption during pregnancy can help reduce the...

Canned Tuna

Connie K. Ho for redOrbit.com — Your Universe Online A band of consumer groups recently joined together to urge the USDA to remove tuna from school lunch menus following a study that found that canned tuna in lunchrooms had high levels of mercury. In an article by WebMD, the non-profit Mercury Policy Project (MPP) recommended that children “should never eat albacore tuna,” young children should only eat tuna once a month, and older kids can eat tuna twice a month....

Nanotechnology Detected Mercury In Water And Fish

Inexpensive, super-sensitive device detects even low levels of toxic metals in water, fish When mercury is dumped into rivers and lakes, the toxic heavy metal can end up in the fish we eat and the water we drink. To help protect consumers from the diseases and conditions associated with mercury, researchers at Northwestern University in collaboration with colleagues at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, have developed a nanoparticle...

Mercury Levels Measured: Water-borne Toxic Metals Detected With Nano-velcro
2012-09-10 16:35:34

A strip of glass covered in hairy nanoparticles can cheaply and conveniently measure mercury, which attacks the nervous system, and other toxic metals in fluids. Researchers at the Swiss Federal Institute of Technology (EPFL), Northwestern University and the University of Michigan found that their new method can measure methyl mercury, the most common form of mercury pollution, at unprecedentedly small concentrations. The system, which could test for metal toxins in drinking water and...

Study Compares Mercury Levels In Wild vs. Captive Dolphins
2012-05-23 04:44:45

Researchers from Johns Hopkins University and the National Aquarium have completed a study, funded by the National Aquarium and by the Center for Contaminant Transport Fate and Remediation at The Johns Hopkins University, which compared the mercury levels of captive dolphins and wild dolphins. Captive dolphins are fed a diet of small fish from the North Atlantic, while the wild dolphins eat aquatic creatures that have potentially higher mercury levels. The researchers discovered that the...

Circumpolar Rivers Most Responsible For High Levels Of Mercury In The Arctic
2012-05-23 04:17:55

Brett Smith for RedOrbit.com If global warming trends are to continue, thermometers across the globe aren´t the only place that mercury levels will be on the rise. The concentration of mercury in the Arctic environment is directly related to forces associated with climate change, according to a new study from Harvard University researchers. Both atmospheric forces and the flow of circumpolar rivers carry the toxic metal north into the Arctic Ocean, but it turns out that the...

Humans pump thousands of tons of vapor from the metallic element mercury into the atmosphere each year, and it can remain suspended for long periods before being changed into a form that is easily removed from the atmosphere. New research shows that the upper troposphere and lower stratosphere work to transform elemental mercury into oxidized mercury, which can easily be deposited into aquatic ecosystems and ultimately enter the food chain. "The upper atmosphere is acting as a chemical...

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...
