"The present study adds to the accumulating evidence linking higher levels of pesticide exposure to adverse developmental outcomes," the study concluded. Roughly 40 organophosphate pesticides are registered with the US Environmental Protection Agency for use in the United States, and about 33.11 million kilograms of the pesticides were used in agricultural and residential settings in 2001, figures cited in the study said.
Although residential pesticide use is common, the National Academy of Sciences found that the major source of exposure for infants and children comes through the diet, the study added. According to a 2008 report cited by the study, detectable levels of pesticides were found in a range of vegetables. A sample of produce tested found 28% of frozen blueberries, 20% of celery and 25% of strawberries contained traces of one organophospate, known as malathion.
Other types of pesticides were found in 27% of green beans, 17% of peaches and 8 per cent of broccoli. According to the US Centres for Disease Control and Prevention, roughly 4.5 million children aged between 5 - 17 had been diagnosed with ADHD up to 2006. Between 3 and 7% of school-aged children in the United States suffer from the condition, figures show.
So, the importance of organic food for children is no longer just a health fad. There is compelling evidence to show the advantages of avoiding pesticides.
