(Beyond Pesticides, March 27, 2019) Exposure to commonly used pesticides in the womb and during the first year of life is linked to a higher risk of developing autism, according to the study, âPrenatal and infant exposure to ambient pesticides and autism spectrum disorder in children: population based case-control study,â published in the journal BMJ last week. Although the study does not reveal a causal link, it adds to previous literature highlighting autism risks from pesticide exposure, and reinforces calls to limit pesticide exposure during early life critical windows of vulnerability. The authors note their findings âsupport the need to avoid prenatal and infant exposure to pesticides to protect the developing child’s brain.” Researchers used data from Californiaâs records of autism disorder diagnosis and birth rates from 1998 to 2010. Roughly thirty-five thousand healthy patients acted as a control, while scientists identified nearly three thousand patients with an autism diagnosis, of which 445 also displayed a co-occurring intellectual disability. Data was then drawn from Californiaâs pesticide use recording database, and eleven pesticides (glyphosate, chlorpyrifos, diazinon, acephate, malathion, permethrin, bifenthrin, methyl bromide, imidacloprid, avermectin, and myclobutanil) were analyzed for their use within 2000 meters (1.25 miles) of the homes of those […]

(Beyond Pesticides, March 26, 2019) In a study investigating the carcinogenic effects of pesticide exposure by analyzing data on 316,270 farmers and farmworkers in the U.S., Norway, and France, researchers have identified elevated risk for non Hodgkin lymphoma (NHL) and some subtypes, linking glyphosate and large B-cell lymphoma. Other pesticides linked to the disease include the pyrethroid deltamethrin and chronic lymphocytic leukemia/small lymphocytic lymphoma; and terbufos and NHL overall. Researchers also found âinverse associations of NHL overall with the broader groups of organochlorine insecticides and phenoxy herbicides, after adjusting for exposure to other pesticidesâ; such inverse associations were not found with active ingredients within these groups. The research underscores how complex the science of pesticide impacts on human health, and on cancer incidence, can be. To wit: in evaluating 14 different pesticide categories and 33 individual, active chemical ingredients, Maria E. Leon, et al., conclude that associations of pesticides with the development of NHL appear to be (NHL) subtype- and chemical-specific. Published in the International Journal of Epidemiology in mid-March, the study, âPesticide use and risk of non-Hodgkin lymphoid malignancies in agricultural cohorts from France, Norway and the USA: a pooled analysis from the AGRICOH consortium,â uses data from three large cohort […]

(Beyond Pesticides, February 15, 2019)Â A study, published in January 2019 in the journal Environmental Health, demonstrates that consumption of organic foods reduces significantly the levels of synthetic pesticide residues in the bodies of U.S. children and adults. Pesticide residues are found four times as frequently in conventionally grown food as in organically produced foodstuffs. Although the number of subjects in this study was relatively small, the results point to the importance of organics, and add to the evidence that organic food production and consumption are key to protecting human health. Study subjects comprised members of racially diverse families â from Oakland, Minneapolis, Baltimore, and Atlanta â who did not typically consume an organic diet. Study participants, ages 4 to 52, ate their typical diet of conventionally grown foods for five days; for the following six days, they switched to a certified organic diet (provided by researchers) for consumption at home, work, school, or daycare, including all foods and beverages other than water. Urine samples were gathered prior to the âorganicâ days, and first thing on the morning after those six days. Fourteen different pesticides and metabolites were present in all participantsâ urine in the âpre-organicâ analysis; following the organic diet […]

(Beyond Pesticides, October 18, 2018) Pesticide residue doesnât announce itself âit isnât colored, it doesnât glow or reflect light, and after an initial application doesnât put out a discernible odor – but it is likely ubiquitous in rural U.S. homes, according to a study published by Cornell University researchers late last month. The study is a warning specifically to households with young children, who are at increased risk of health effects from even minute levels of pesticide exposure. âNumerous health problems occur from exposure to pesticides, such as cancer, birth defects, leukemia and ocular [vision-related] toxicity, among a number of other health issues,â said Joseph Laquatra, PhD, coauthor of the research. âHouseholds with crawling toddlers should be concerned, as toddlers will accumulate pesticide residues on their hands and then ingest them due to hand-to-mouth behaviors.â Researchers focused in on 132 households in rural counties of New York State that agreed to test for pesticide residue inside their home. Wipe samples were collected from both carpeted and non-carpeted areas, and tested for pesticides used commonly as part of agricultural production in the region. The pesticides analyzed included 15 compounds ranging from organophosphates like chlorpyrifos and malathion, to synthetic pyrethroids like resmethrin, […]

(Beyond Pesticides, June 22, 2018) Mosquito misters pose a threat to human health. They also harm bees and other flying pollinators and are the least effective way to deal with biting mosquitoes. These devices are typically placed outdoors and spray insecticides âmostly in an attempt to control mosquitoes. In May, the Connecticut state legislature voted to ban the use of residential pesticide misting systems. Urge your Governor and state legislators to ban pesticide misters. In addition to the threat to peopleâs health, misters harm pollinators who may be foraging in an area where the devices are used. Studies find that sublethal concentrations of synthetic pyrethroids significantly reduce bee fecundity and decrease the rate at which bees develop to adulthood and reproduce. Field and laboratory studies using pyrethroids have consistently documented decreases in foraging activity and activity at the hive entrance after exposure. While pesticides are regulated by the U.S. Environmental Protection Agency (EPA), pesticide misters and other application devices are not subject to EPA oversight, leaving states with the authority to control their use. Connecticut appears to be the first state to restrict pesticide misting machines through legislation. The state of New York took an administrative approach to regulating these devices, as the commissioner of the […]

(Beyond Pesticides, May 23, 2018) Earlier this month, the Connecticut state legislature voted to ban the use of residential pesticide misting systems. (These are devices that are typically placed outdoors and spray insecticides –mostly in an attempt to control mosquitoes.) This is the latest move from a state legislature that has also recently banned the use of bee-toxic neonicotinoids and stopped the use of hazardous lawn care pesticides on public playgrounds. The vote was unanimous in the state Senate, and won by a count of 132-17 in the state House. The bill is set to become law on May 24, unless Governor Malloy vetoes the legislation, which is not expected. Pesticide misters are machines primarily used to spray mosquito adulticides. Many health advocates have expressed concern that these products, able to spray toxic pesticides on a timer at regular intervals, pose a significant risk to pets and children who can be directly in the path of a misterâs spray. The chemicals employed in these machines are often synthetic pyrethroids, which have been linked to a range of human health effects, from early puberty in boys, to behavioral disorders, learning problems, ADHD, and certain cancers. Neighbors who do not want to be […]

(Beyond Pesticides, February 20, 2018)Â The U.S. Centers for Disease Control and Prevention (CDC) finds that the U.S. Environmental Protection Agency (EPA) label restrictions on total release foggers, otherwise known as âbug bombs,â are a public health failure. Bug bombs pose a significant risk of acute illness to individuals even when they attempt to follow new label instructions. Beyond Pesticides has long called for bug bombs to be banned, as there are a myriad of non-toxic alternative strategies to successfully manage household pests. Urge your Governor to ban bug bombs in your state! Bug bombs are small cans primarily comprised of an insecticide, often a synthetic pyrethroid, a synergist such as piperonyl butoxide (PBO), and an aerosol propellant. In addition to the explosion/fire risk if the aerosol product is used in an unattended home near a pilot light or other spark-producing appliance, both synthetic pyrethroids and PBO pose acute and chronic human health risks. PBO is added to pesticide formulations to increase the toxicity of synthetic pyrethroids, and has been linked to childhood cough. Peer-reviewed research associates synthetic pyrethroids with behavioral disorders, ADHD, and delayed cognitive and motor development, and premature puberty in boys. Not only can bug bombs acutely poison, […]

(Beyond Pesticides, February 14, 2018) Total release foggers, otherwise known as bug bombs, received updated labels from the U.S. Environmental Protection Agency (EPA) in 2011 as part of efforts to reduce accidental poisonings, but a new report from the U.S. Centers for Disease Control and Prevention (CDC) finds that EPA restrictions are a public health failure. Bug bombs pose a significant risk of acute illness to individuals even when attempting to follow new label instructions. Beyond Pesticides has long called for bug bombs to be banned, as there are a myriad of non-toxic alternative strategies to successfully manage household pests. CDCâs report, Acute Illnesses and Injuries Related to Total Release Foggers, updates a previous study released in 2008 which found significant safety concerns about bug bombs and ultimately prompted EPA to revise the labels of these products. At the time, CDC found a total of 466 illnesses or injuries associated with the use of total release foggers between 2001-2006. Incidents ranged from failing to leave an area after releasing the bug bomb, reentering the premises too early, use of too many products for the space provided, and even explosions related to the ignition of aerosols released from the product. Bug […]
