Until now, parents of children with autism who have spoken up about their fears that their child's disorder came on the heels of vaccination have been given the status of heretic. But it turns out that the increase in autism we have been witnessing over the last few decades could also be a result of the over-all increase in the body burden caused by mercury in our air and water, and by proxy the fish we eat, our vaccines and dental fillings, and now, in our high fructose corn syrup, a substance marketed and consumed most often by those most at risk: children.

It is a matter of record that our fish populations are accumulating mercury; and as the top of their food chain, we too are accumulating the toxin. The neurological effects of mercury have been widely documented. On the EPA's website, for example, it lists the primary health effect of methylmercury on fetuses, infants, and children, as being impaired neurological development.

In 2004, a study [PDF] led by Raymond F. Palmer of the University of Texas Health Science Center in San Antonio compared the rate of special education programs in Texas and the amount of mercury found in the environment and the results were alarming: "On average, for each 1000 lb of environmental mercury released, there was a 43% increase in the rate of special education services and a 61% increase in the rate of autism."

He co-authored a second study [PDF] from February 2008 that took into account the proximity to sources of mercury output -- like coal-fired utility plants, which account for 33% of the 158 tons of mercury spewed into the atmosphere annually, municipal/medical incinerators, which account for 29%, commercial/industrial boilers, which account for 18%. Lower on the list but still noteworthy are hazardous waste sites, cement factories, and the chlorine production plants -- which is where the caustic soda tainted with mercury in High Fructose Corn Syrup (HFCS) is being produced. This second study found that "for every 10 miles from industrial or power plant sources, there was an associated decreased autism Incident Risk of 2.0% and 1.4%, respectively." In other words, the more mercury in the environment of a child or woman of childbearing age, the more likely for the child to develop autism.

The reason that the news on Monday that HFCS contains mercury is so alarming is two fold: First, the FDA had evidence of this in 2005 and did absolutely nothing -- no testing, no warning the companies using the tainted HFCS to produces their ketchup, chocolate syrup, cereal bars and soda. Therefore, more time has passed when mercury could bio-accumulate in our bodies, especially in populations at already at risk for heart disease, diabetes and obesity. Second, there has been a previous association made between diet and autistic functionality -- and specifically HFCS has been singled out as a cause for worsening the disorder. This means that there has been a growing body of evidence relating mercury to autism for some time, in which HFCS is only a new development.

This is dark news, because it means that our FDA is no longer working for us, and that in this time when we might have a receptive ear in Washington, it is more important than ever to challenge the preconceived notions of how government works. This could amount to one of the worst offenses by our government, which has been sitting on the evidence of mercury's relationship to our health for too long in the name of corporate welfare.

The parents of autistic children should be given more of a voice in this discussion. In an article published on Salon.com in 2005, Robert F. Kennedy, Jr. laid out the details on the correlation between autism and childhood vaccines. It became clear to him that the parents of autistic children who blamed the vaccines for their child's disorder were onto something when he stumbled onto a report from a conference in 2000 called Simpsonwood, where high-level officials from the FDA and Center for Disease Control (CDC), the top vaccine specialist from the World Health Organization in Geneva, and representatives of every major vaccine manufacturer, including GlaxoSmithKline, Merck, Wyeth and Aventis Pasteur gathered to discuss a new study that linked a mercury-based preservative in vaccines to increasing rates of autism. This group, instead of changing course, and giving value to the science before them, proceeded to cover up the data to save the vaccine companies' bottom line.

Now, we are faced with some hard truth about the consequences of our environmental choices beginning at the Industrial Revolution. While thimerosal, the mercury-laden preservative used in some vaccinations, is being phased out, we should still be asking for a better assessment of our body burden of mercury. With all that we know now, about what toxic pollution in the air and water do to our food and by proxy our bodies, will we face facts and begin the process of real, lasting change that the Obama administration has so far seemed a beacon for? The first step will be taking a hard look at environmental mercury, one of the most prevalent pollutants in our environment. We have a mess on our hands, and we need to begin to repair the damage done before we can move forward healthfully.
