Environmental Toxins is a broad term to describe toxins in the air, water and/or food supply that are known or suspected to cause a number of diseases and conditions. There are currently over 80,000 chemicals used in North America contributing to a large increase in the amount of environmental toxins that one is exposed to. Many of these chemicals and toxins have been designed for convenience and to improve profitability without thought of their long-term effects on human health and the environment. It has been stated that 90% of all chronic and serious illness could be prevented if we were able to eliminate 600 of the most dangerous environmental toxins.

- Parabens (Methyl, Propyl, Butyl, and Ethyl Paraben)
- PCBs (polychlorinated biphenyls)
- Perfluorooctanic Acid (PFOA)
- PVC (polyvinyl chloride)
- Pesticides and herbicides
- Phthalates (DEHP, DINP, DIDP, DBP, DnOP, DnHP)
- VOCs (Volatile Organic Compounds)
- Other Environmental Toxins
Associated Symptoms and Conditions
Environmental toxins can affect every organ and system of the body and contribute to a number of symptoms including:
- General Symptoms
- chronic or progressive neurological problems such as numbness and tingling
- alteration in cognitive abilities – “brain fog” (often you may indicate a specific spot on your head that feels abnormal) or neuro-cognitive difficulties (speech, reasoning, focus)
- ADD, ADHD, concentration, focus and/or memory concerns
- Autism, ADD, mental retardation, and cerebral palsy have been linked to environmental toxins such as lead, arsenic, toluene, PCBs and methylmercury.
- dementia and delayed reaction and mental processing
- psychological problems and mood alterations (depression, anger, nervousness, emotional instability, etc)
- nausea, vomiting, diarrhea or other bowel concerns
- intestinal dysbiosis and alterations in appetite, weight
- increase in food intolerances
- abdominal pain, stomach cramps, burning of the throat or mouth
- irritable bowel syndrome, Crohn’s disease, etc.
- liver or kidney disease or dysfunction
- cancers including (colon, pancreatic, stomach, rectal, liver, kidney or bladder)
- impaired motor function, loss of balance or coordination
- abnormal gait, posture, or movements
- muscle and joint pain
- osteoporosis and other bone disorders
- hypotension or hypertension
- cardiovascular disease, peripheral vascular disease and alterations in heart rate
- anemia, alterations in blood counts and blood vessel damage
- respiratory infections – laryngitis, pharyngitis, bronchitis, pneumonia
- difficulty breathing, asthma, restrictive airway disorders, pulmonary fibrosis
- cancers (lung, respiratory tract or blood)
Total Body Burden
Total body burden, also known as environmental toxic load is a term that is used to describe the accumulation of chemicals and toxins in the body (less the minerals available to neutralize them).
- These substances accumulate as a result of the food you eat, what you drink, the air you breathe, the products you use on our skin and in your home and garden.
- They also accumulate based on the products used in businesses and industry such as plastics of various kinds, fire retardants and industrial chemicals, herbicides, pesticides, and fungicides and bleaching materials and those that exist in the environment at large.
- Your body burden is affected by your exposure and your body’s ability to assimilate and excrete the toxins.
- Excretion is highly variable and determined by an individual’s genetics, nutritional status, antibiotic use, lifestyle and total toxic load.

- An environmental toxic burden is exhibited when the level of net retention exceeds physiological tolerance.
- As the body is unable to remove many of the inorganic toxic chemicals and heavy metals on its own, the burden that these compounds are having on health is a major problem.
Testing for Environmental Toxins
There are many different ways to test for environmental toxins. The best way, depends on the type of toxin and the health of the individual. Some of the most common ways include:
- World Health Organization www.who.int
- Grandjean P, Landrigan PJ. Developmental neurotoxicity of industrial chemicals. Lancet;2006 Dec 16;368(9553):2167-78. PMID: 17174709.
