Environmental Research Gets Short-Shrift in National Autism Research Agenda
By Theresa Wrangham SafeMinds President

tkw The public comment period concerning the update of the National Institutes of Health Interagency Autism Coordinating Committee's (IACC) strategic plan for autism research closed last week. Now, additional information on the upcoming science workshop has been revealed.

The workshop will be held early in September. Its purpose is to engage the scientific community in identifying new research objectives or amendments needed to existing objectives within the strategic plan. Not surprisingly, environmental expertise in the workshop is again limited, which is likely to result in yet another iteration of the strategic plan that lacks cutting-edge research priorities in environmental science. Amid fresh concerns regarding conflicts of interest held by IACC Chair Dr. Thomas Insel and his ability to provide objective leadership, the composition of the science workshops was changed mid-stream, most notably excluding the critical voice of public member and vice president of SafeMinds, Lyn Redwood.

Why is this significant? Initial composition of these workshops called for one federal and one public IACC member from the IACC's strategic planning subcommittee, of which Ms. Redwood is a member. As it now stands, five panels will address updating research objectives within the strategic plan, and Ms. Redwood will not be on any of these panels, despite her requests to participate. These actions are yet another example of the inherent lack of balance between public member (6) and federal member (12) representation on the committee, which has served to block vital environmental research that relates to the etiology, treatment, and prevention of autism.   Read more.
 
Top 10 Sources of Mercury you can do Something About - #2 Dental Amalgams
By Katie Weisman for the SafeMinds Environmental Committee

katie weisman According to the EPA, dentists in the United States use approximately 34 tons of mercury per year.
 
Silver fillings aren't primarily silver and never have been.  Since they were developed in France in the early 1800's, their main ingredient has always been mercury.  Today's amalgam typically consists of about 50% elemental mercury alloyed with varying amounts of silver, tin, copper and zinc.  Amalgam releases mercury vapor continuously throughout the time it is in your mouth. The amount of vapor released is increased by chewing (when the fillings are located on the occlusal surfaces), by tooth brushing and by consuming hot liquids. Approximately 80% of the mercury vapor will be absorbed into your body where it will deposit itself in your nervous system, kidneys, liver and thyroid gland. 
 
There has been ongoing controversy over the health risks of dental amalgam internationally.  The WHO estimates that amalgam fillings are the greatest source of daily mercury exposure in those who have them, greater than all other sources combined, and ranging from 3-27mcg per day.  A study done in 1998, estimated that, "on average, each ten-surface increase in amalgam exposure is associated with an increase of 1mcg/L mercury in urine." (Kingman et al.) Dental associations, generally, have strongly fought the notion that there are negative health effects from mercury amalgam, but studies are ongoing.  It is well-established now that about 23% of patients with mercury amalgam will show systemic allergy to inorganic mercury.  Mercury amalgam can also be the cause of lichenoid lesions in the mouth.   Patients with poor kidney function should not receive amalgams because of their impaired ability to excrete mercury.  Read more.

Blood Mercury Levels Rising Among
From Health Day News

A study involving more than 6,000 American women suggests that blood levels of mercury are accumulating over time, with a big rise noted over the past decade. Using data from the U.S. Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey (NHANES), a researcher from the University of California, Los Angeles, found that while inorganic mercury was detected in the blood of 2 percent of women aged 18 to 49 in the 1999-2000 NHANES survey, that level rose to 30 percent of women by 2005-2006.

"My study found compelling evidence that inorganic mercury deposition within the human body is a cumulative process, increasing with age and overall in the population over time," study author and neuroscience researcher Dan R. Laks said in an UCLA news release. "My findings also suggest a rise in risks for disease associated with mercury over time."  Read more.

Congress Can Stop Mercury Pollution from Chlorine Plants
By Scott Laster for the SafeMinds Environmental Committee

Do you want to help reduce mercury in the environment, but don't know where
to start?  

Here's one major step that can be done right now - Congress can  pass a pending bill to stop mercury pollution from chlorine manufacturing  plants.  Even though 95 percent of US chlorine is made without the use of mercury, four outdated plants continue to use old technology that relies upon hundreds of tons of mercury.  Collectively, these plants release hundreds of pounds of mercury into our air and water every year. When released into the environment, the mercury can cause neurological damage when we breathe it in air or eat fish in which the mercury has accumulated.  Pregnant women and children are particularly susceptible.  The newer technology costs less to operate and produces higher capacity.  Prudence
dictates that these four plants update their equipment now.

The Mercury Pollution Reduction Act, H.R. 2190 in the House and S. 1428 in the Senate, would make the outdated "Foul Four" chlorine plants update their
equipment to modern technology that doesn't utilize or release mercury.  The Mercury Pollution Reduction Act was originally authored by then-Senator Obama in 2006, and was re-introduced in 2009.  Recently, the House Subcommittee on Commerce, Trade and Consumer Protection moved the bill to the full House Energy and Commerce Committee for their consideration and the Senate version of the bill was introduced.

Oceana, an organization which campaigns to protect and restore the world's oceans, has been leading the push to introduce and pass these laws. SafeMinds applauds their efforts to eliminate a major source of mercury contamination.  If you would like to learn how you can take action, please see the Oceana website.
