Scientifically, it’s been documented children continually are exhibiting lower IQs, aka the Flynn effect, decade after decade.
Jun 14, 2018 – IQ scores have been steadily falling for the past few decades for those born after 1975. [Paraphrased from 1]
Fluoride exposure in drinking water has been blamed, as have neurotoxic chemicals in vaccines. Both can be classified as epigenetic effects, not genetics!
However, not much exposure has been given to a certain classification of agricultural pesticides known as Chlorpyrifos, first manufactured in 1965 by Dow Chemical Co., now known as DowDuPont after a 2017 merger with DuPont.
The chemical Chlorpyrifos is an organophosphate pesticide that affects the nervous system of insects by inhibiting acetyl cholinesterase, a key enzyme for neurotransmission. It apparently can have similar effects in children’s brains, especially during gestation, i.e., pregnancy.
Question: Will the chlorpyrifos saga go the route of Monsanto’s Roundup® after Bayer merged with Monsanto, who apparently got a “pig in a poke” with all the thousands of lawsuits being filed against Roundup? That remains to be seen.
However, the following information should convince consumers to avoid chlorpyrifos-treated crops and opt for organically-grown food.
According to Earth Justice,
Chlorpyrifos is used on a wide variety of crops including apples, oranges, strawberries, corn, wheat, citrus and other foods families and their children eat daily.
In fact, over half of all apples and broccoli in the U.S. are sprayed with chlorpyrifos. USDA’s Pesticide Data Program found chlorpyrifos residue on citrus and melons even after being washed and peeled. By volume, chlorpyrifos is most used on corn and soybeans, with over a million pounds applied annually to each crop.  [CJF emphasis]
Other food crops include almonds, cotton [seed oil used in processed foods], grapes, broccoli, sugar beets, peaches and nectarines, according to the Organic Consumers Association. 
Beyond Pesticides adds, “It is also commonly used for mosquito-borne disease control, and on golf courses.”  Additionally, Beyond Pesticides says, “[As] a neurological toxicant, chlorpyrifos damages the brains of young children: impacts of exposure, even at very low levels, include decreased cognitive function, lowered IQ, attention deficit disorder, and developmental and learning delays.” One more reason to purchase organically-grown baby food!
“On Aug. 9, 2018, the 9th Circuit Court of Appeals ruled that EPA must finalize its proposed ban on chlorpyrifos within 60 days, based on undisputed findings that the pesticide is unsafe for public health, and particularly harmful to children and farmworkers. “The Court ended EPA’s shameful actions that have exposed children and farmworkers to this poison for decades,” said Earthjustice attorney Marisa Ordonia. “Finally, our fields, fruits, and vegetables will be chlorpyrifos-free.” 
However, according to Organic Consumers Association,
The revelation comes as the U.S. Environmental Protection Agency (EPA) is duking it out in the legal system over a court ruling that the agency finalize a ban on chlorpyrifos that was proposed under the Obama administration, but overturned after Trump took office. On September 24, the EPA—the agency charged with protecting us from environmental contaminants—asked the courts to re-hear the case. [Yuk!] 
Beyond Pesticides has an online pdf file “Widely Used Pesticide in Food Production Damages Children’s Brains EPA science on chlorpyrifos ignored as agency reverses decision to stop insecticide’s agricultural use,” which I encourage consumers to study carefully with regard to the following:
Chlorpyrifos effects on children’s brain function Studies have documented that exposure to low levels of chlorpyrifos during pregnancy can impair learning, change brain function and alter thyroid levels of offspring into adulthood, especially in females. 1,2,3,4 [CJF emphasis]

The Organic Consumers Association is encouraging everyone to TAKE ACTION: Tell the EPA to ban—now—this pesticide [Chlorpyrifos] that damages children’s brains.
As OCA says, “It’s high time for the EPA to stop stalling, and start protecting kids and farmworkers instead of chemical companies like Dow.”
