PRINCETON, N.J. — I spent this week at the Animal Behavior Society meeting at Princeton University, which, when you're an animal blogger, is something like releasing a kid in a candy store. Seven-hundred-and-fifty scientists from around the world had gathered to give each other updates on all creatures great and small, marine and terrestrial and airborne. Here are a few things I learned:
Mercury may make birds mad as a hatter!
The liquid metal mercury is toxic, even in small doses. In humans, large doses cause lethargy and depression. Smaller amounts result in dementia. But what does low-dose mercury poisoning do to a bird? John P. Swaddle of the College of William and Mary and colleagues exposed zebra finches to an amount of mercury consistent with a contaminated environment. Poisoned birds were bolder and hyperactive, but they were also lower in rank and spent less time feeding than birds that had not been exposed to the metal. With the birds displaying no signs of depression, hyperactivity would put them more on the dementia side of mercury poisoning, Swaddle said during his August 11 presentation. And that, he noted, could lead to an increased risk of predation.

NGO calls for mercury amalgam phase-out following Committee assessment
12 September 2014 / Europe,Risk assessment
The European Environmental Bureau (EEB) has welcomed the European Commission's preliminary opinion on the safety of dental amalgam and its alternatives, which was published last month by the Scientific Committee on Emerging and Newly Identified Health Risks (Scenihr) (CW 11 September 2014).
The NGO says the study “shows that it is now time to phase out mercury use in dentistry, for at least pregnant women and children, but also for adults”, and calls for measures to abolish its use completely.
Scenihr's assessment concludes that alternative materials to amalgams should generally be a first choice, but also calls for further research into the potential neurotoxicity of mercury and the toxicity profile of alternative dental materials.
Dentists have been using dental amalgam to fill cavities for more than 150 years. Now one group is suing the FDA, claiming that people are getting sick and that silver fillings need to be banned.
“I was trying to avoid mercury when I was pregnant and nursing,” said Amy Forseter. “I knew all the fish not to eat, but I had no idea it could be in my mouth.”
Forseter has had more than a dozen cavities, most of them filled with dental amalgam, a mixture of metals that’s 50 percent liquid mercury, a naturally occurring element that’s highly toxic.

New Report From Consumers for Dental Choice Clearly Shows that Americans are Measurably Misled About the Mercury in Their Dental Fillings!
After decades of hearing their mercury-based dental fillings called "silver" and "amalgam" by their dentists and the FDA, it shouldn't be surprising that Americans are feeling more than a little misled about what's being put in their mouths.
A new report released today by Consumers for Dental Choice, based on a poll by Zogby Analytics, makes clear that deliberately misleading terms for mercury-based dental fillings have led to deliberately misled consumers.
A copy of the report and poll findings is available here.
