Autism and Endocrine Disrupting Chemicals

With my introduction to the wolrd of autism a few years back came a slurry of rather disturbing information. First is the extreme rise over the past 30 years, then the attempt to find causation and treatments. From 1993 to 2003 autism diagnoses increased 800%. The million, make that billion, dollar question: “what is causing this increase?”. While much is disagreed upon in the autism community one theory leads the way and that is that autism is like cancer. That is a genetic predisposition component and environmental triggers that can result in something along the pervasive developmental disorder continuum.

What are these environmental triggers? With cancer we know of many carcinogens, with autism it seems fitting to look at known neurotoxins: mercury, lead, various pesticides, endocrine disruptors, and the like. The science and research is still very young (and underfunded) which leaves many unknowns.

If you spend enough time in the research and looking at the numbers it can be a really frightening scenario especially for those about to start a family. The choices that a parent has to make seem to be getting more and more difficult maneuvering through baby bottles, crib mattresses, vaccines, food, personal care products, toys, and even the clothes we bring them home in. While it can be a little startling at first, we as a society have left things unchecked for too long and a little forethought is worth a lifetime of health.

About a month ago I ran into this article on endocrine disrupting chemicals (e.,g. BPA) by Dr. Harvey Karp which draws some conclusions as to their possible roles in autism.

New Website: Food, Pesticides & Toxicology

Today I ran across the new website from the Pesticide Action Network, What’s On My Food? This website uses a formula similar to that on the Skin Deep Database only in relation to chemicals on food and the documented research on those chemicals rather than chemicals in skin care items. It is a great resource to click on and see the various chemicals that the USDA’s Pesticide Data Program has found in various foods cross referenced with data from the EPA and authoritative research.

Pesticide regulations in the U.S. are well behind much of the rest of the industrialized world. This is mostly because agrichemical corporations like Monsanto have too much influence in Washington, but also because pesticide regulation in the U.S. does not adequately account for things like additive and synergistic effects.

Since the Environmental Protection Agency (E.P.A.) regulates most chemicals on a chemical-by-chemical basis, the combined and cumulative effects of a mixture of pesticides are nearly impossible for them to address – and so they usually don’t. 1

In addition to this handy tool, they have  a lot of really great information and links to research. They have links and document the growing body of research on the effects of pesticides on human and environmental health from the various exposures: working or living near crops where pesticides are used, prenatal exposure, exposure through food, and exposure through runoff into streams, rivers, aquifers, lakes, and oceans.

Given the complexities of chemical causality and disease-formation, the smart solution would be to follow the European Union’s lead and adopt the “precautionary principle”2 as the basis for regulatory decision-making. Put simply, this approach prioritizes protecting human health when there is significant doubt about the safety of a product. By contrast, pesticides and industrial chemicals in the U.S. are innocent until proven guilty. It often takes decades to prove a chemical guilty.

Meanwhile, we are exposed to dozens of pesticides in the food we eat, water we drink and air we breathe. People working on farms or living in rural areas near non-organic agricultural fields face even higher exposure levels.

My transformation from someone who lived very chemically intensively to someone who works diligently to reduce the amount of chemicals in my life and the lives of others began in 2005 when I began to work with children with autism. When sifting through the research on autism it is impossible to ignore the various research linking chemicals to the condition. Then your mind stats to wonder about the rise in other health-related issues: Parkinson’s, cancer, asthma, depression, ADHD, pre-term births, endometriosis, infant mortality (to name a few). As you dig deeper and deeper the research presents a not so great picture. Instead of pull myself into isolation in some remote village less damaged from chemical pollution, I decide to do what I can and help others to realize the need to reduce the amount of chemicals we currently support through our consumption patterns.

To begin with I eliminated all chemicals from my house: the pesticides I used in the garden, the cleaners under the sink, skin care products, perfume… Then I saw the need to eat as organically as possible for me, my unborn children, and millions of farm workers around the world. And then I took a good hard look at my clothing and the textile industry and realized that if I were to buy new supporting organic cottons and sustainable fibers was the only way to go. Conventional cotton uses 25% of the world pesticides and if I truly want to live my life in a way the respects the quality of life and health for all there is no way to justify not supporting the more sustainable options. Once you see the world as a contained system in which we are all connected and realize the ill effect that can be cause by a single shirt the organic and sustainable textile industry becomes a pivotal part in the quest for a better future.

The following is an excerpt from the What’s On My Food Website:

How are we exposed?

» In our bodies
» On the farm
» In the environment
» On our plates

In our bodies

Most of us are born with persistent pesticides and other chemicals already in our bodies, passed from mother to child during fetal development. The human health impacts linked to pesticide exposure range from birth defects and childhood brain cancer in the very young, to Parkinsons’ Disease in the elderly. In between are a variety of other cancers, developmental and neurological disorders, reproductive and hormonal system disruptions, and more.

On the farm

Most of us are born with persistent pesticides and other chemicals already in our bodies. Farmers and farmworkers are some of the hardest working people on the planet. Yet they and their families bear the highest health costs and face the greatest risks of pesticide exposure. Farmworkers in particular remain the least protected class of workers in the U.S. – last year another slavery case was brought in Florida on behalf of farmworkers there. Poisoning incidents among farmworkers are vastly underreported – yet in California alone, hundreds of cases of pesticide poisoning are documented every year.

Occupational exposure to pesticides in acute cases range from dizziness and nausea to death; chronic exposures are linked to the same array of diseases listed above plus a few more listed below.

In the environment

Pesticides don’t stay where they’re applied. They drift from their target and are carried in our air, oceans, rivers, groundwater and soil. They contaminate ecosystems and can poison fish, birds and wildlife. Water supplies around the world contain measurable amounts of pesticides, including atrazine. Atrazine, a suspected endocrine disruptor recently banned in Europe3, is the most commonly used herbicide in the U.S.

Besides heavy use in industrial farming, pesticides are used in or near playing fields, parks, schools, public gardens, golf courses, grocery stores, offices, apartment buildings, hotels and resorts, airplanes, cruise ships — the list goes on. Rural communities are routinely contaminated by pesticide drift, while city dwellers may trace pesticide residues on their shoes to public parks and even their apartment’s common areas.

Attention: to Those Touched by Autism

The Defeat Autism Now! Conference will be coming to the Embassy Suites Conference Center in Norman, Oklahoma  June 13th & 14th.  The Defeat Autism Now! Conference is put together by the Autism Research Institute, a non-profit dedicated to solving the puzzle of autism through ongoing research into the causes and treatments for autism.

The Autism Research Institute is comprised of Medical Doctors, Behavior Analysts, Nutritional Consultants, Researchers, and various other professionals that continue the pursuit of helping individuals with autism. I went to a Defeat Autism Now! Conference in California and was blown away by the amount of vigorous scientific research that was being conducted on autism, it’s causes, and the treatments.

Listening to the various speakers, it was interesting to hear numerous medical professionals who were taught that there is little you can do for individuals with autism. They were satisfied with this conclusion until having children of their own diagnosed with autism at which point they became obsessed with research. Through much intensive research they discovered many medical issues that come along with an autism diagnosis that are medically treatable. I was sitting next to a dad, who had colitis himself and a non-verbal son with autism, who was nothing short of terrified during a video of various intentional scopes done on a number of children with autism. I remember him talking about his excruciating pain associated with his colitis and that his scopes were not as bad as the ones the showed that day.

There is no way that I could relay the vast amount of information that will be presented at the Defeat Autism Now! Conference. They thoroughly cover topics from intestinal permeability, food allergies, to environmental issues, to heavy metal exposure, to oxidative stress and much more.

If your life has been touched by autism you should attend this conference. If you know of anyone whose life has been touched by autism please relay this information.

Autism Increase a Reality — New Study

I stopped questioning whether the increase in autism was due to better and earlier diagnoses while working in the schools and having Special Education teachers that had been working for 20 years say that in the past few years “the number of autistic-like students had increased year after year, no matter what you diagnose them as that type of student was increasing in numbers.” I even witnessed an increase in the few years I was working in the schools and while children with autism are all different there are enough similarities to have a feeling for someone on the spectrum.

A new study by researchers at U.C. Davis M.I.N.D. Institute published in January’s Issue of the peer-reviewed journal Epidemiology gives even more weight to the actual increase in cases of autism and the need for more research into possible environmental triggers. A great synopsis of the study can be found on the Autism Society of America’s website.

I fell in love with every child that I worked with, these children are truly beautiful. Their personalities are nothing short of charming and magical. However, education and medical expenses for children with autism can place an enormous financial and emotional burden on parents and without intensive one-on-one education as well as other therapies their quality of life declines drastically. So while I truly cherish and love these children for who they are, I do not wish the struggle on anyone.

Certainly there are some genetic components at work, but it is not all genetic and research does need to focus more on chemicals and their effect on neurodevelopment if we are going to get any real answers. Autism is what opened my eyes to the insane chemicals that I had incorporated into my everyday life from garden pesticides to cleaning chemicals to air fresheners to cosmetics. Most of the chemicals we use today have had little to no testing. Research available shows many chemicals to be carcinogenic, neurotoxic, and endocrine disrupting in laboratory testing yet they are found in many common household products. For the most part ingredients are required to be fully disclosed so the consumer is able to adequately asses these chemicals (with a little research). One exception is ingredients that fall under trade secrets such as “fragrance”. When you see “fragrance” as an ingredient know that you may be getting more than what you bargained for as phthalates (many of which have recently been banned for use in products for children under the age of 12)  extend the life of a fragrance and are considered to be trade secrets so they do not have to be labeled. A resource I find helpful in evaluating ingredients is Environmental Working Group’s Skin Deep Database. Even if the products you are wanting information on are not in the database itself you can pull up research on the ingredients themselves.. All of this to say that we as consumers need to be as educated as possible about the products we bring into our homes to protect the health of our families.

Why Organic Cotton: A Synopsis

Why support Organic Cotton? Conventional cotton is very harsh on the environment and the health of those working in the fields. Conventional cotton accounts for about 25% of the worlds pesticides and considering the toll that pesticide poisoning takes, there is great incentive to reduce their usage. This does not even touch the health effects on those living near pesticide intensive areas.

A Study published in 2007 in Environmental Health Perspectives found that in California maternal proximity to heavily sprayed agricultural crops resulted in an increase in children diagnosed with autism. Then further down the chain much damage is done to the wildlife and the build up of chemicals in the soil, air, and water comes back to us when we eat, breath, and drink. Additionally, from the fetal stage through the first few years of life children are far more sensitive to environmental toxins due to the developing blood-brain barrier and immune system. This is an extremely critical time to avoid xenobiotics that could cause neurobehavioral impairment, reproductive damage, immune dysfunction, and increased risk of cancer because of the massive development that is taking place.

Organics and Autism

Why am I such and ardent organics supporter and promoter? Well, I have not always been this way; in fact it was only a few short years ago that I told my then husband to be that we did not need to pay attention to the ingredient list we just needed to look at the nutrition label (fat, calories, protein…). Much has changed and all can be attributed to my journey with autism.

I began working with children with autism about 4 years ago. These precious children stole my heart and have captured my mind. In the beginning I wanted to know more; the more I learned the more I realized was unknown. One thing I kept running into was chemicals in the environment which I blew off at first. However it stuck in my mind and I noticed that everyone of the kids in the autism room in which I worked had a mother who was an avid gardener. I was newly married and had myself developed a love for digging in the dirt and growing plants. I was a conventional gardener and used any chemical I could get my hand on to keep insects at bay. At the time my thought was that if it was sold in the store it was safe, ha! One day I stopped and read the label of the toxic sludge that I was dishing out to keep my plants from being eaten. What was this that needed to be flushed for 10-15 minutes if skin contact is made? And who really flushes their skin that long? I was shocked by the long list of neurotoxins and carcinogens that I was eagerly applying to the garden. In hopes that I was just being paranoid I had Jeremy, who was working in a neuroengineering lab, research the chemicals further. To no avail, the first of many life changes was on the horizon. We then went from the garden to the chemicals I was cleaning with and then to the food. The following summer I was doing some volunteer work and looked at the ingredients on the snacks we were handing out to the kids and noticed TBHQ. What is TBHQ? TBHQ is butane and it is used as a preservative in our food… what? Really, butane is an allowable ingredient in food.

At this point I was convinced of the need to reduce the chemicals in our environment and that one way I could do that was to support organics. However, I had not yet taken my support of organics to clothing — it just had not occurred to me. After all, I was not eating clothing and washing would surely take care of the chemicals. Then in October of 2007 a study was published in Environmental Health Perspectives the results of which showed that the rates of autism spectrum disorders increased with the poundage of organochlorine pesticides and the the mothers proximity to the field site while pregnant. Further research revealed that the crops for which organochlorine pesticides are primarily used are cotton, soybeans, and rice. Now I had a problem because I could no longer feel good about buying cotton because it was a natural product; in doing so I was contributing to a lot of chemical contamination.

This is when I began to think about the entire impact of my actions. What had before been a simple act of going to a store and purchasing something turned into a chain of events that led back to the birth of the raw materials of that product and the effect that product had on the lives it touched on its way to me. We can change the world by being a little more conscious of our purchases.

Autism and Precipitation

An interesting study was published this month in the Journal of the American Medical Association under the archives of Pediatrics and Adolescent Medicine. The study, Autism Prevalence and Precipitation Rates in California, Oregon, and Washington Counties, and found that autism prevalence rates were positively related to precipitation totals. As the autors explain, this positive relationship could be due to a number of environmental factors including: more time indoors with more exposure to indoor chemicals (such as those used in household cleaning products), less time in the sunshine which results in lower vitamin d levels, and the precipitation itself carrying some unidentified pollutant. While there is much disagreement in the field of autism, the most commonly held viewpoint is that autism is a lot like cancer in that there are genetic predispositions and various environmental triggers that contribute to the disorder. I will be posting some of my favorite studies, both past and present, as autism is what initially opened my eyes to the need to embrace a cleaner, more sustainable life.
