Attention deficit/hyperactivity disorder (ADHD) is a chronic neurobehavioural disorder with a complex etiology thought to involve genetic expression, learning and childhood development, diet, neurotransmitters, and neurotoxic exposure to pollutants. Treatment generally involves a multi-factorial approach that addresses any number of these factors with pharmacological or behavioural-based interventions.  Addressing the known impacts of neurotoxic pollutants, which are summarized in this paper, may enhance successful treatment or prevention of ADHD. An advisory committee from the United States National Research Council found that 3% of all developmental disabilities are a direct result from exposures to environmental pollutants, and a further 25% extend from genetic susceptibilities to environmental factors. Serum lead levels of  >0.12nmol/L have been correlated with incidence of ADHD, particularly if associated with low iron levels (ferritin 65% of children and adults with ADHD). Modified citrus pectin, ferrous sulphate, chelation therapy, improved detoxification pathways using s-adenosyl methionine, cysteine or glutathione as well as removing exposure to pollutants or other environmental or dietary allergens may be beneficial naturopathic approaches towards individualized treatment or prevention of ADHD.
