Persistent Organic Pollutants, including Banned Pesticides, Remain Present in all Fetal Organs Regardless of Maternal Chemical Contamination   (Beyond Pesticides, September 16, 2021) "A study published in Chemosphere finds persistent organic pollutants (POPs), including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs), are present in the serum and placenta of pregnant mothers, as well as multiple fetal organs... However, this study is one of the first to demonstrate the presence of chemical toxicants in fetal tissue that are not present in maternal serum or placental samples. Prenatal development is one of the most vulnerable periods of exposure when the fetus is most susceptible to the harmful effects of chemical contaminants."

Kids Who Eat Organic Food Score Higher on Cognitive Tests, Study Finds    (Beyond Pesticides, July 7, 2021) Organic food consumption among children is associated with higher scores on tests measuring fluid intelligence and working memory, research published in the journal Environmental Pollution finds. This spanish study looked at all exposures... Likewise, the result associating organic food consumption with higher rates of cognition could be indicative of socio-economic status as opposed to specific food consumption.' Many previous studies have shown a higher pesticide burden in children and how pesticides affect development.Links.

Living Within 2.5 Miles of Chemical Farming Increases Risk of Childhood Brain Tumors  (Beyond Pesticides, April 6, 2021) Pregnant women living within 2.5 miles of agricultural pesticide applications have an increased risk that their child will develop central nervous system (CNS) tumors, according to a study published in the journal Environmental Research by a team at University of California, Los Angeles. The results are particularly concerning as it reveals that individuals do not have to be in close contact with pesticides for risky, health-harming exposures to occur.    For astrocytoma tumors, the use of the pesticides bromacil, thiophanate-methyltriforine, and kresoxim-methyl increased risk of tumor development. Medulloblastoma was associated with the use of chlorothalonilpropiconazoledimethoate, and linuron. Development of ependymoma was linked to nearby use of thiophanate-methylIn sum, the pesticides chlorthalonilbromacilthiophanate-methyltriforinekresoxim-methyl, propiconazoledimethoate, and linuron were all linked to elevated rates of a CNS tumor. SNAP Comment: California is one of the only locatins where such a study can be performed because they keep pesticide use data. In Saskatchewan, we don't even have pesticide sales data since 2003! The transition from farmland to residential is equally abrupt in SK.  As of 20 April 2021, the number of registered products of the pesticides quoted above are registered by the PMRA: Linuron 4 (herbicide) (annual weeds in crops); bromacil, 6 (herbicide); thiophanate-methyl,(fungicide) 13. included uses for seed potatoes ((not an extensive search of uses); Triforine,2 (fungicide) for blueberries, other berries and fruit);  kresoxim-methyl 2 (fungicide) for pear scab and powdery mildew; chlorothalonil,38 labels (fungicide) formarket gardens, corn and fruit, golf courses, ornamentals and aerial applications (not an extensive search of uses); propiconazole,65 labels (fungicide) turf, golf courses.

Over 100 Chemicals Detectable in Pregnant Women, Including 98 “New” or Unknown Compounds   (Beyond Pesticides, March 25, 2021) 'A new University of California San Francisco (UCSF) study, published in Environmental Science & Technology, finds over 100 chemicals present in U.S. pregnant women’s blood and umbilical cord samples. This discovery ignites concerns over prenatal exposure to chemicals from consumer and industrial products and sources. Furthermore, 89 percent of these chemical contaminants are unknown sources and uses, lacking adequate information, or are not previously detectable in humans. This discovery ignites concerns over prenatal exposure to chemicals from consumer and industrial products and sources.    The study detects 109 chemicals within blood samples of mothers and newborns, including pesticides, plasticizers, compounds in cosmetics and consumer products, pharmaceuticals, flame retardants, and per- and polyfluoroalkyl substances (PFAS) compounds. Of the 109 chemicals, 55 lack preceding reports on their presence in humans, and 42 chemical compounds have little to no information regarding chemical classification, use, and source of contamination.'

EPA Fails to Follow Congressional Mandate to Protect Children from Pesticide Exposure   (Beyond Pesticides, February 13, 2020) Congress unanimously passed the Food Quality Protection Act (FQPA) in 1996 to increase protections for children from pesticide exposure. Unfortunately, according to a new study published in Environmental Health, the law is not being employed by the Environmental Protection Agency (EPA) to its full capacity. For most of the 59 pesticides reviewed by the study, EPA did not apply an additional FQPA safety factor and thereby missed an opportunity to protect children’s health. In fact, FQPA solidified EPA’s reliance on risk assessment calculations and mitigation measures that consistently fall short of adequate levels of protection because of serious data gaps, a failure to consider exposure to mixtures and synergistic effects, and a bias against consideration of alternatives (alternatives assessment)  that show toxic pesticides to be unnecessary.    SNAP Comment: Does anyone know whether Canada is supposed to apply an additional safety factor for children in pesticide registration?

New neuroimaging testing shows how prenatal exposure to organophosphate pesticides changes the development of children’s brains   (The Organic Center, Sep 23, 2019) . OP (Organophosphate) exposure was associated with altered brain activation during tasks of executive function. For example, with a 10-fold increase in total OP pesticide use within 1 km of maternal residence during pregnancy, there was a bilateral decrease in brain activation in the prefrontal cortex during a cognitive flexibility task. We also found that prenatal OP exposure was associated with sex differences in brain activation during a language comprehension task. This first functional neuroimaging study of prenatal OP exposure suggests that pesticides may impact cortical brain activation, which could underlie previously reported OP-related associations with cognitive and behavioral function.

The Pesticide Generation   Children on the Front Line  (Webdoc.France24.com,original FRANCE 24 multimedia documentary has been translated from the original in French, 2019)  A court case against glyphosate and what is happening in France about banning glyphosate. "The medical community is unambiguous: Théo’s malformations are not genetic, but definitely linked to an external factor. “Right from birth, Théo’s doctors pointed a finger at pesticides,” says Sabine, who at the time didn’t make an immediate connection to the weed killer that she used at home to spray the horse paddock. “The wake-up call came later,” she remembers. In August 2008, to be precise. Just as she did every year at the same time, Sabine treated the area with Glyper, a herbicide containing glyphosate. “It suddenly hit me; I remembered what the surgeon had told me about pesticides.” Due to the teratogenic risks of glyphosate causing malformation of embryos and foetal abnormalities cited in scientific studies, doctors say the link to Théo’s birth defects is “highly likely”. “I was exposed to glyphosate at a crucial moment in my pregnancy – during the first four weeks,” she says. “I didn’t even know I was pregnant, so I didn’t take any particular precautions.'

Kids Carry Higher Levels of Glyphosate in Their Bodies than Adults, Study Finds  (Beyond Pesticides, August 7, 2019) significantly higher. '...recent data from the American Cancer Society (ACS) indicat)es) that pediatric cancer in the U.S. surged by almost 50% from 1975 to 2015... Results showed that over 90% of participants had been recently exposed to glyphosate. In most child/parent pairs, the child’s body had surprisingly higher concentrations of glyphosate (up to 4 times that of the parent), supporting research that glyphosate poses a greater threat to children. While the American Cancer society (ACS) is for the most part silent on the impact of pesticides on childhood cancer, the Canadian Cancer Society (CCS) recognizes these risks. (links) 

Exposure to pesticides can raise blood pressure in kids    (Sara Middleton, staff writer, NaturalHealth365, June 26, 2019)   'The innocent children’s exposure to harmful chemicals like organophosphates – which are already linked with hypertension according to the National Institutes of Health – caused them to develop hypertension, especially soon after toxin exposure. To make matters even worse, the affected kids also demonstrated diminished self-control, attention, visuospatial processing, and sensorimotor function! ' with link to the scientific article about pesticides. The article also discusses natural ways of lowering blood pressure. 

Protecting Children from Pesticides: Information for Parents (healthychildren.org, 29 Ma4ch 2017)  The American Academy of Pediatrics (AAP) policy statement, Pesticide Exposure in Children, and accompanying technical report highlights some of the major health concerns linked to pesticide exposure—particularly prenatal exposure.

Glyphosate and other toxins in throw away diapers. Du glyphosate et des substances chimiques dangereuses dans les couches jetables pour bébés. Une expertise inédite de l’Anses conclut à un risque pour la santé des enfants. Le gouvernement demande aux fabricants d’éliminer ces produits.(by Stéphane Mandard. Le Monde, le 22 janvier 2019)   Le Monde is an important paper from France. For those who don't speak French, glyphosate was one of over 60 toxic substances identified in throw away diapers. There were also several other pesticides, some which have been banned 15 years ago (lindanequintozène, hexachlorobenzène).Throw away diapers also contained many problematic fragrances, PCBs and VOC (volatile organic compoinds) such as (naphtalènestyrènetoluène, etc.) (By the way, naphthalene is also an insecticide found in mothballs).

Brain and Behavioral Effects of Early Exposures to Neurotoxicants  (University of California Television (UCTV), Aug 11, 2015)  There is also a significant link to meaningful tremors and learning deficits. This presentation addresses the impact of prenatal exposure to a common neurotoxicant on brain structure and neuropsychological function in an inner-city cohort of minority children. The toxic chemical, an organophosphate insecticide (chlorpyrifos), has been banned for indoor residential use in the U.S. since 2001, but continues to have widespread application for agricultural purposes. Possible moncholinergic mechanisms involve disruption of neural cell development and neurotransmitter systems, including the formation and activity of synapses in different brain regions. This presentation examines the evidence for long-term effects of prenatal chlorpyrifos exposure on neuropsychological profiles and brain morphology as measured by MRI.

Common Mosquito Control Insecticides Decrease Motor Function in Infants (Beyond Pesticides, June 13, 2017) Prenatal exposure to commonly used mosquito and agricultural insecticides is associated with decreased motor function in infants, according to a study published in Environment International by a team of Chinese and U.S. researchers...For the current study, over 350 pregnant Chinese mothers were tested for the presence of organophosphate pesticides in their umbilical cord blood. Researchers looked at exposure to the insecticides naledmethamidophostrichlorfonchlorpyrifos, and phorate. After giving birth, their children’s motor function was tested at both six and nine months of age. Significant changes were seen at the 9 month testing. For naled, scores for visual motor, fine motor, and fine motor quotients decreased 0.55, 0.85, and 0.90 points lower per 1 ng/mL increase in naled originally detected in an infant mother’s cord blood. With chlorpyrifos, reflexes, locomotion, grasping, VM (visual motor), GM (gross motor), FM (fine motor), TM (total motor), GMQ (gross motor quotient), FMQ (fine motor quotient), and TMQ (total motor quotient) are, respectively, 0.50, 1.98, 0.80, 1.91, 3.49, 2.71, 6.29, 2.56, 2.04, and 2.59 points lower, when comparing exposed and unexposed infants, according to the study. SNAP Comment: Chlorpyrifos is still used for mosquito control in Edmonton, Alberta. I don't know about naled use in Canada. These are more of a concern when traveling, I guess, including in Florida which is known to use Naled.

Exposure to Heavy Pesticide Use Can Impact Neurobehavioral Performance in Children (Beyond Pesticides, May 12, 2017) Researchers have found that exposure to heavy pesticide use during peak periods can impact neurobehavioral performance in children. The study focused on exposure to organophosphate pesticides, which have been associated with a broad range of diseases in both children and adults...Dr. Suarez-Lopez continued, “This discovery is novel because it shows that pesticide spray seasons can produce short-term alterations in neurobehavioral performance in addition to the long-term alterations that have been previously described. This is troublesome because the altered mental functions observed are essential for children’s learning, and in May-July, students typically take their end-of-year exams. If their learning and performance abilities are affected in this period, they may graduate from high school with lower scores which may hinder their ability to access higher education or obtain a job.”

Glyphosate Use Could be Linked to Pregnancy Problems  (Beyond Pesticides, April 11, 2017) New data presented last week at a children’s health conference show that glyphosate, the active ingredient in the popular Roundup weed killer, is detected in pregnant women and could lead to adverse pregnancy outcomes, including shorter gestation times and lower birth weights. Researchers tested and tracked 69 expectant mothers and found that the presence of glyphosate levels in their bodily fluids correlated with unfavorable birth outcomes. 

Australian Study Finds Nearly Half of Insecticide Poisonings Affect Young Children (Beyond Pesticides, August 16, 2016) Young children are disproportionately poisoned by toxic pesticides used indoors, according to a study published in the Australian and New Zealand Journal of Public Health. Data analyzed from the Queensland, Australia Poisons Information Centre (QPIC) finds that 49% of 743 insecticide-related calls in 2014 concerned young children...A significant share of childhood pesticide poisonings occurred in very young children.

Report presents effects of pesticide exposure on children  (By Jean Ruzicka, Park Rapids Enterprise, May 14, 2016) The article is from a Minnesota paper commenting on the Minnesota part of the report Kids on the Frontline, recently produced by PANNA. Indeed, Minnesota agriculture is the most similar in crops, and likely pesticide use to Saskatchewan, barring corn and soy although more is being grown in the South every year. I would love to see a similar Canadian report, but with no pesticide use data collected and detailed pesticide use by province considered 'trade secret' by the PMRA, one could never get there. I guess we will forever remain ignorant. Don't you know "Ignorance is bliss?"

 A Generation in Jeopardy: How pesticides are undermining our children’s health & intelligence (PANNA, October 2012) In the US, more than 1 billion pounds of pesticides used annually have contributed to an array of health problems in youth...10% of children born annually in the United States are estimated to be affected by neurodevelopmental disorders. One-third of all neurodevelopmental disorders are caused either directly by pesticides and other chemicals or by genetics and exposure to environmental factors, the National Academy of Sciences estimates. Exposure to pesticides has also been linked to lower IQ levels in children.

Prenatal Exposure to Widely Used Pesticide Ingredient Linked to Childhood Cough (Beyond Pesticides, September 12, 2012) Expectant mothers exposed to the pesticide additive piperonyl butoxide (PBO), widely used in synthetic prethroid insecticides and those ending in “thrin” (popular in mosquito spray programs), during pregnancy pass to their children a heightened risk of noninfectious cough at ages 5 and 6, according to researchers at the Columbia Center for Children’s Environmental Health (CCCEH). These findings support the premise that children’s respiratory system is susceptible to damage from toxic exposures during the prenatal period...

Common Herbicide May Increase Risk of Rare Disorder in Infants (Beyond Pesticides, October 2, 2012) The herbicide atrazine may be linked to an amplified risk of choanal atresia, a congenital abnormality of the nasal cavity, according to researchers at Baylor College of Medicine and other Texas institutions. Choanal atresia is recognized when tissue formed during fetal development blocks an infant’s nasal cavity. Though it is a rare condition, it is considered quite serious because it can affect an infant’s ability to breathe...

Everyday Exposure to Pesticides Linked to Attention-Deficit Hyperactivity Disorder (Beyond Pesticides, May 18, 2010. Posted in ADHD, Chemicals, Children/Schools, Chlorpyrifos, Disease/Health Effects) Eexposure to organophosphate (OP) pesticides, at levels common among U.S. children, may contribute to a diagnosis of ADHD. This is another study illustrating that regulatory agencies (US EPA as well as Canada's PMRA) evaluate harm based on false realities about daily toxic exposure and individual sensitivities. Risk management decisions under these laws assume the benefits of toxic pesticide products to society or to various sectors of users, then make a determination that the risks are “reasonable.”...

Children susceptible to Pesticides Longer Than Expected (2009-06-22) One's PON1 genotypic profile determines how effectively the enzyme can metabolize toxins. The ability to metabolize toxins remained low in a large proportion of children up to age 7. The study authors recommend that the U.S. Environmental Protection Agency (EPA) re-evaluate the current standards for acceptable levels of pesticide exposure. The fact that enzyme activity remained low for certain kids with vulnerable genotypes well past age 2 was surprising for the study authors.
