Take Action: Tell Your Public Officials to Stop Spraying Pesticides and Adopt a Safe, Effective Mosquito Management Plan

Monday, September 10th, 2018

(Beyond Pesticides, September 10 2019) Does your community spray toxic pesticides for mosquitoes? In a well-intentioned but ill-informed attempt to prevent mosquito-borne illness such as West Nile virus, many communities spray insecticides (adulticides) designed to kill flying mosquitoes. If your community is one of these, then your public officials need to know that there is a better, more-effective, way to prevent mosquito breeding. Tell your public officials to stop spraying pesticides and adopt a mosquito management plan that protects public health and the environment. The problem with mosquito pesticides. Two classes of insecticides are favored by mosquito spray programs –organophosphates and synthetic pyrethroids. In order to better target flying mosquitoes, adulticides are generally applied as ultra-low-volume (ULV) formulations that will float in the air longer than usual. Organophosphates, which include malathion (Fyfanon), naled (Dibrom), and chlorpyrifos (Mosquitomist), are highly toxic pesticides that affect the central nervous, cardiovascular, and respiratory systems. Symptoms of poisoning in humans include: numbness, tingling sensations, headache, dizziness, tremors, nausea, abdominal cramps, sweating, incoordination, blurred vision, difficulty breathing, slow heartbeat, loss of consciousness, incontinence, convulsions, and death. Some organophosphates have been linked to birth defects and cancer. Breakdown times range from a few days to several months, depending […]

Weeds on Missouri Cropland Found To Be Resistant to Six Different Herbicides

Thursday, August 2nd, 2018

(Beyond Pesticides, August 2, 2018) Weed scientists from the University of Missouri (UM) have just published evidence of a water hemp population resistant to six different herbicides. The study is sending shock waves throughout the chemical-intensive agricultural community, particularly in light of the plant’s resistance to 2,4-D. In its reporting on the study, KTIC Rural Radio begged the question, “If we’re already seeing 2,4-D resistance now, what will happen when use of the herbicide becomes even more commonplace?” KTIC is referring to the impending commercialization of products like Enlist Duo, developed by DowDupont in an attempt to address widespread weed resistance to glyphosate. Enlist Duo is an herbicide containing both glyphosate and 2,4-D, and is intended to be sprayed only on crops genetically engineered (GE) to tolerate exposure to both chemicals. However, with growing reports like this, many farmers may begin to rethink their approach. In 2014, a farmer contacted UM indicating that water hemp was not responding to 2,4-D during a regular ‘burndown’ the farmer conducted before planting a new crop. (Chemical-intensive farmers will often use a synthetic herbicide to clear their field for new plantings.) The farmer had also used other herbicides, fomesafen and glyphosate, in this process […]

Famous Mountain Lion Known to Cross California Freeway Found Dead from Suspected Rodenticide Poisoning

Tuesday, July 31st, 2018

(Beyond Pesticides, July 31, 2018) P-55, a mountain lion, famous for crossing Southern California’s notorious 101 Freeway, has died of causes biologists suspect are related to rodenticide poisoning, according to the National Park Service (NPS). The radio collar strapped to P-55, aged 3, failed to transmit that the animal has died, and, when biologists found him, his remains were too decomposed to determine the exact cause of death. NPS officials indicate that there are two likely scenarios that lead to the death of a healthy mountain lion: a fight with another male, or poisoning from rodenticides. Although decomposed, officials indicate there were no signs of a struggle where his body was found. This is the latest incident in Southern California linking rodenticide use to the poisoning of mountain lions. In 2014, it was reported that another mountain lion in the region, P-22, also famous for its propensity to roam near Griffith Park’s Hollywood sign, was nearly killed from mange and poisoning brought on by rodenticide exposure. Despite policies passed at the state and local level, secondary poisoning of non-target predators by rodenticides still poses a risk to wildlife. In 2014, California Governor Brown signed AB 2657, which banned the use […]

Research Evidences Roles of Low-Dose and Synergistic Exposures Missed in Pesticide Regulation, Citing Parkinson’s Disease

Tuesday, June 12th, 2018

(Beyond Pesticides, June 12, 2018) Two recent studies are contributing to the growing understanding that challenges basic toxicological precepts as inadequate to comprehensive assessments of impacts, particularly in the realm of human exposures to chemicals. One investigation tackles the role of chemical pesticide exposures in the risk of developing Parkinson’s Disease. That study appeared in The FASEB (Federation of American Societies for Experimental Biology) Journal in April 2018. The other, published earlier this year in the journal Food and Chemical Toxicology, assesses potential negative health outcomes of long-term, low-dose exposure to admixtures of chemicals that more realistically represent real-life exposures than those typically created in a lab setting — one chemical at a time. A basic concept of the classical scientific method is that relationships among phenomena, whether causal or associative, can be evaluated only through the isolation and consideration of elements one at a time. A core tenet of toxicology is the dose-response notion: that the lesser or greater the dose or exposure, the smaller or larger, respectively, the organismic response will be. Paracelsus is credited for the terse summary, “The dose makes the poison.” Most research into the health and environmental risks of toxic chemicals in the materials stream […]

Take Action: Local Governments Must Act to Protect Us from Glyphosate

Monday, June 11th, 2018

(Beyond Pesticides, June 11, 2018)  With news that the U.S. Environmental Protection Agency (EPA) allows Roundup and its active ingredient glyphosate to be used despite evidence that it causes developmental effects following low-dose exposure, it is crucial that citizens demand that local governments provide the protection that EPA refuses. A pilot study —the first stage of the Global Glyphosate Study by the Ramazzini Institute (Italy) released in May— found that doses of either glyphosate or Roundup considered “safe” by EPA produce genotoxicity, alterations in sexual development, and changes in the intestinal microbiome. Tell your local leaders to take action to protect families from pesticides! This study adds to the urgent need for action, given previous findings that Roundup is: (1) linked to cancer by the International Agency for Research on Cancer, and its subsequent listing on California’s Prop 65 (“chemicals known to cause cancer”) list; (2) promoted by its manufacturer, Monsanto, on the basis of questionable research practices; and (3) challenged in a consensus statement by scientists and medical doctors. Glyphosate is not the only pesticide to which we all, including children, are exposed in schools and parks, but it is widely used and portrayed as “safe.” In order to protect […]

“Global Glyphosate Study” Finds Health Impacts at Levels Regulators Consider Acceptable

Friday, May 25th, 2018

(Beyond Pesticides, May 25, 2018) The results of a pilot study conducted by an international team of researchers finds that exposure to the herbicide glyphosate results in adverse health effects at levels below those regulators deem “safe” or acceptable. These results represent the first phase of a Global Glyphosate Study based at the Ramazzini Institute in Bologna, Italy, in coordination with the University of Bologna, the Italian National Institute of Health, George Washington University, and the Icahn School of Medicine at Mount Sinai, NY. Researchers are aiming to provide a truly independent, comprehensive evaluation of the risks posed by glyphosate-based herbicides. The pilot study, available now on the research team’s website and later this month in the journal Environmental Health, focused on generating data on how glyphosate effects early-life stages of development. A three-month study on rats, used as a surrogate for human development until 18, exposed the animals to both technical grade glyphosate and the formulated herbicide Roundup. Rats ingested 1.75 miligrams of glyphosate or Roundup per kilogram of body weight each day from the womb until 13 weeks after weening. This is the chronic reference dose used by the U.S. Environmental Protection Agency, and an exposure rate at which the […]

Pesticides Contaminate Fish Farms, Fish Farm Fined

Wednesday, May 16th, 2018

(Beyond Pesticides, May 16, 2018) Northern Harvest Sea Farms, an ocean-based fish farm in New Brunswick, Canada, was appeared in court yesterday to answer legal charges stemming from the off-label use of an unnamed pesticide added to its operations to combat severe sea lice outbreaks. The company holds nine licenses for farmed Atlantic salmon cages on the Bay of Fundy, as well as for fish farms off the Newfoundland coast. Sea lice outbreaks are a common at over-crowded, ocean-based fish farms because such facilities afford the optimum conditions for rapidly reproducing and spreading lice. In response, some companies have turned to using illegal and off-label pesticide applications to stave off the problem, which causes huge farmed salmon kills. The company was issued a $12,000 fine that was challenged as inadequate by the Grand Manan Fishermen’s Association. Bonnie Morse, project manager for the association told Canadian Broadcasting Corporation (CBC) news, “I think any time there’s a fine that’s a deterrent to illegal activity, it should be an actual deterrent to the activity,” said Morse. “When you’re looking at $1.5 million worth of fish, their actions speak for themselves.” Maria Recchia, the executive director of the Fundy North Fishermen’s Association, questioned the allowance of fish […]

FDA Scientists Find Glyphosate in Common Foods, Internal Emails Show

Wednesday, May 2nd, 2018

(Beyond Pesticides, May 2, 2018) Granola, cereal, and wheat crackers all contain “a fair amount” of glyphosate, the herbicide in Monsanto’s popular Roundup, according to internal emails from the Food and Drug Administration (FDA). Although the results of these tests have not been formally released, FDA had stated it will be conducting tests for glyphosate in food. Previous reports have detailed the presence of glyphosate, the chemical classified as a “probable carcinogen,” in a wide range of foods and in people’s bodies. Internal emails obtained by The Guardian through a Freedom of Information Act (FOIA) request reveal communication between FDA scientists regarding glyphosate residues in common foods. One email, dated January 2017, detail one scientist’s results from foods taken from his own home. “I have brought wheat crackers, granola cereal and cornmeal from home and there’s a fair amount in all of them,” FDA chemist Richard Thompson wrote to colleagues in the email last year regarding glyphosate. He further went on to write that broccoli was the only food he had “on hand” that he found to be glyphosate-free. According to The Guardian, another FDA chemist Narong Chamkasem separately found “over-the-tolerance” levels of glyphosate in corn, detected at 6.5 parts per million, an FDA […]

Action: Glyphosate/Roundup Must Be Removed from the Market

Monday, April 23rd, 2018

(Beyond Pesticides, April 23, 2018) The U.S. Environmental Protection Agency (EPA) is accepting comments on its human health and environmental risk assessments of glyphosate (sold as Roundup™, Rodeo™, and many other products) until April 30. Evidence is mounting that glyphosate products cause cancer and many other human health and environmental problems. Sign the petition asking EPA to ban glyphosate. Despite the prevalent myth that this widely used herbicide is harmless, glyphosate is associated with a wide range of illnesses, including non-Hodgkin’s lymphoma, genetic damage, liver and kidney damage, and endocrine disruption, as well as environmental damage, including water contamination and harm to amphibians. Researchers have also determined that the “inert” ingredients in glyphosate products, especially polyethoxylated tallow amine or POEA –a surfactant commonly used in glyphosate and other herbicidal products— are even more toxic than glyphosate itself. Monsanto, manufacturer of glyphosate, formulates many products (such as Roundup™Â and Rodeo™) and markets formulations exclusively used on genetically engineered (GE) crops. Glyphosate is one of the most widely used herbicides in the world, due in large part to the increased cultivation of GE crops that are tolerant of the herbicide. This petition summarizes the reasons glyphosate should be banned. More information can be […]

Study Shows Glyphosate Linked to Shorter Pregnancies

Wednesday, March 21st, 2018

(Beyond Pesticides, March 21, 2018) According to a new study published this month in Environment Health, women with high levels of glyphosate in their bodies are more likely to have shorter pregnancies. Shorter pregnancies can lead to children with reduced learning and brain development. This is the first study to suggest that exposures to glyphosate can influence the long-term well-being of children. The study, Glyphosate exposure in pregnancy and shortened gestational length: a prospective Indiana birth cohort study, obtained both urine and drinking water samples from 71 women with pregnancies living in Central Indiana while they received routine prenatal care, and analysed the relationships of glyphosate levels in mother’s urine with fetal growth indicators and gestational length. The researchers found that more than 90 percent of pregnant women had detectable levels of glyphosate where higher glyphosate levels were significantly correlated with shortened gestational lengths, even though the drinking water samples had little to no detectable levels of glyphosate. Women living in rural areas were found to have higher glyphosate levels. The authors note their study is significant because it is the first U.S. study designed specifically to measure prenatal glyphosate exposure in pregnant women to determine its association with adverse fetal […]

Take Action: Tell EPA to Ban Paraquat

Monday, February 12th, 2018

(Beyond Pesticides, February 12, 2018)  The most recent findings on the development of Parkinson’s disease after exposure to the highly toxic paraquat add to the well-established body of scientific literature linking the herbicide to Parkinson’s — which should lead to finally eliminating the use of the herbicide in the U.S. The chemical was banned in the European Union in 2007, and many health groups, including Beyond Pesticides and The Michael J. Fox Foundation for Parkinson’s Research, are calling on the U.S. Environmental Protection Agency (EPA) to stop the use of paraquat by denying its upcoming reregistration. In addition to its connection with Parkinson’s disease, paraquat is known to be highly acutely toxic. By generating free radicals, it essentially burns its way through the body, targeting the lungs —causing lung fibrosis— and other organs. Most acutely toxic exposures result in death, sometimes delayed by as much as three weeks. Although paraquat is a restricted use pesticide (RUP), EPA is proposing to eliminate the minimum age for applying RUPs, which would permit teenagers to use it. Tell EPA and Congress to ban paraquat! This link will send the following message to EPA and your Congressional delegation: I urge EPA to join other countries […]

Herbicide Paraquat Again Linked to Parkinson’s Symptoms in Brain

Thursday, February 1st, 2018

(Beyond Pesticides, February 1, 2018) Scientists at the European Institute for the Biology of Aging are finding new information about how Parkinson’s disease manifests itself after exposure to the herbicide paraquat, in hopes of finding ways to prevent the progression of the disease. Despite a well-established body of scientific literature linking the paraquat to Parkinson’s, and a ban on the use of the chemical in the European Union that dates back to 2007, its use is still permitted in the U.S. Many health groups, including Beyond Pesticides and organizations like the Michael J Fox Foundation are calling on the U.S. Environmental Protection Agency stop the use of paraquat by denying its upcoming reregistration. Published in the journal Cell Reports, this new research on Parkinson’s investigates the impact of “senescent” cells in the body. Senescent cells are those which, despite being able to divide, stop doing so in response to stress. This is an anti-cancer mechanism, as stress would otherwise cause the cells to multiply unchecked and create malignancies. Researchers suspected that despite the benefit of stopping cancer, senescent cells may be causing other problems in the body. Rather than dying, these cells can cause inflammation in the area around where […]

Honey Bees Attracted to Glyphosate and a Common Fungicide

Friday, January 12th, 2018

(Beyond Pesticides, January 12, 2018) Honey bees display a concerning attraction to the herbicide glyphosate and the fungicide chlorothalonil at certain concentrations, new research from scientists at the University of Illinois (UIL) reveals. Results are reminiscent of a 2015 study published in the journal Nature, which found that honey bees display a preference for foods treated with neonicotinoids, a class of insecticides implicated in global pollinator declines. Since the crisis became public knowledge in 2006, managed honey bees have experienced unsustainable levels of colony loss, and one in four species of native bees in North America and Hawaii are at risk of extinction. This new research adds to growing concerns that, while neonicotinoids continue to play a primary role in the pollinator crisis, their elimination would still leave a myriad of other toxic chemical threats to the recovery of these critical species, upon which so much of our food supply relies. UIL scientists investigated honey bees’ preference for a range of pesticides as well as a number of naturally occurring chemicals that honey bees would likely encounter in the field. In the experiment, pollinators were put in a large enclosure and allowed to fly to different feeders stocked with either […]

Health Costs from Chemical Exposures May Exceed 10% of the Global GDP

Wednesday, December 13th, 2017

(Beyond Pesticides, December 13, 2017) A recent study finds that environmental exposures contribute to increasing disease burden and corresponding health costs that may exceed 10% of global gross domestic product (GDP). Neurological impairments particularly add significant costs to both individuals and societies. This European study combined cost calculations for exposures to environmental chemicals, including pesticides, air pollution, and endocrine disrupting substances, and suggests that a shift in priority setting for environmental policy is needed. The study’s authors, from Harvard University, the University of Southern Denmark, and the EHESP School of Public Health in France, say that calculations currently used as international references are “serious underestimations” of the economic costs associated with preventable environmental risk factors. Published in Environmental Health, the study, Calculation of the disease burden associated with environmental chemical exposures: application of toxicological information in health economic estimation, combined and extended cost calculations for exposures to environmental chemicals, including neurotoxicants, pesticides, air pollution, and endocrine disrupting chemicals, where sufficient data were available to determine dose-dependent adverse effects. The study utilized risk valuations to assess the environmental burden of disease, and used country-specific monetary values of metrics for length and quality of life (Disability-Adjusted Life year or DALY – a […]

Fungicides Tied to Declining Bumblebee Populations in the United States

Tuesday, December 5th, 2017

(Beyond Pesticides, December 5, 2017) Fungicides are likely playing an important role in the decline of North American bumblebee populations, according to new research published by a team at Cornell University. While overwhelming data continue to indicate that insecticides, particularly the neonicotinoid class of chemicals, are the leading factor in overall pollinator declines, Cornell scientists discovered that fungicides, in particular the chemical chlorothalonil, are likely compounding risk and toxicity for U.S. bumblebee species. As new studies continue to expand the chemical culprits in pollinator declines, calls for a wholesale change in agricultural practices toward more sustainable organic production are reinforced. Cornell researchers began their investigation by focusing on what land use factors had the most impact on eight bumblebee species, many of which have been declining in the U.S. Bumblebee species were sampled at nearly 300 sites in 40 states during the summer months, and at each of the sampling sites, landscape variables were characterized and quantified for land use (urban v rural), habitat (high vs low latitude), and pesticide (insecticide, fungicide, herbicide) usage. The strongest indicator of declining range within the selected bumblebee species was found to be overall fungicide use, with those in the northern U.S. undergoing the […]

Study Finds Pesticides Take the Buzz Out of Bumblebees

Tuesday, November 28th, 2017

(Beyond Pesticides, November 28, 2017) Bumblebees exposed to field-realistic levels of neonicotinoid insecticides have problems with “buzz pollination” that results in reduced pollen collection, according to new research published in Scientific Reports. This is the latest science to tease out the complex ways in which neonicotinoids interfere with these important pollinators, providing yet another reason to eliminate these highly toxic, systemic insecticides from the environment. Flowers that bumblebees pollinate require the insects to emit soundwaves, or ‘sonicate’ to release their pollen, and bumblebees must perfect their techniques over time in order to maximize the pollen they are able to collect. Researchers tested the effect of neonicotinoids on bumblebees’ sonication abilities by exposing them to field realistic doses of the insecticide thiamethoxam at rates of 2 parts per billion (ppb) and 10 ppb, and observing their ability to successfully collect pollen. A control group that never came in contact with thiamethoxam was also used to compare the progress of the exposed group. Lead author of the study, Penelope Whitehorn, PhD, indicated, “We found that control bees, who were not exposed to the pesticide, improved their pollen collection as they gained experience, which we interpreted as an ability to learn to buzz […]

Trump Administration Seeks Delay in Court-Ordered Review of Neurotoxic Pesticides

Friday, November 17th, 2017

(Beyond Pesticides, November 17, 2017) The Trump Administration is asking a federal court to delay a prior agreement that National Marine Fisheries Service (NMFS) issue findings on the risk of three highly toxic organophosphate pesticides to endangered species. The move is widely seen by environmental advocates as influenced by the chemical industry, in particular the new agrichemical conglomerate DowDuPont, which completed a megamerger in September. The Trump Administration’s ongoing willingness to do the bidding of the chemical and pesticide industry means that voters must speak out to their elected representatives to stem the tide of chemical poisonings in the U.S. In 2014, the Center for Biological Diversity (CBD) sued the U.S. Environmental Protection Agency (EPA) for its failure to comply with the Endangered Species Act (ESA), which requires the agency’s pesticide registration process to include consultations with federal wildlife agencies, including NMFS and the Fish and Wildlife Service. In this case, the pesticides in question are chlorpyrifos, malathion, and diazinon, three highly toxic chemicals used as nerve agents during WW2 and registered as pesticides since the 1960s. EPA’s failure to consult with these agencies is a chronic problem in the pesticide registration and review process, leaving critical gaps in the […]

Research Shows Common Insecticides Harm Songbird Migration, Raises Concerns of a New Silent Spring

Tuesday, November 14th, 2017

(Beyond Pesticides, November 15, 2017) Songbirds exposed to widely used insecticides fail to properly orient themselves for migration, according to a study published by Canadian scientists in Scientific Reports. With the organophosphate chlorpyrifos and the neonicotinoid imidacloprid applied to millions of acres of farmland throughout North America, this new research adds weight to arguments that pesticides are a likely cause in the decline of migratory bird populations. “Studies on the risks of neonicotinoids have often focused on bees that have been experiencing population declines. However, it is not just bees that are being affected by these insecticides,” said Christy Morrissey, PhD, biology professor at the University of Saskatchewan. Researchers captured 57 white crowned sparrows in northern Canada, and held them in an outdoor pen for roughly two weeks, during which time all the birds either gained or maintained their weight. The songbirds were then split into three groups, one exposed to imidacloprid, another to chlorpyrifos, and the last untreated and acting as a control. The imidacloprid and chlorpyrifos exposed groups were each further separated by exposing a portion to the insecticide at 10% of the lethal dose that would kill 50% of a given population (LD50), and another to 25% […]

Industry Influence Undermines Protection from Hormone-Disrupting Chemicals

Tuesday, October 31st, 2017

(Beyond Pesticides, October 31, 2017) Scientists warn that inadequate federal testing, disproportionate industry influence, and subverted regulatory oversight threaten decades of progress on protecting people from hormone disrupting chemicals. This from a new paper with findings that regulators face a critical need to fully understand and address the hazards from these dangerous substances. Hormone disrupting chemicals, also known as endocrine disruptors, are substances that have been shown to interfere with the hormone system, leading to long-term health impacts ranging from cancer to neurological developmental impairments. Even small alterations in hormone concentrations, particularly during “critical windows” of embryonic development and developmental phases of life, can have lasting and significant effects. Mounting science is showing that disruptions to the hormone system can occur at very low doses that are lower than those used in traditional toxicity testing. Now, commentary from scientists at Rutgers University and North Carolina State University, “Endocrine disrupting chemicals and behavior: Re-evaluating the science at a critical turning point,” states that inefficient federal testing and outsized industry influence in Washington threaten decades of progress. “The significant progress made over the past couple of decades to understand endocrine disrupting chemical-related effects and mitigate exposures is now at serious risk,” write the authors […]

Pesticide Residues Difficult to Wash Off Food

Friday, October 27th, 2017

(Beyond Pesticides, October 27, 2017) In a study published in the Journal of Agricultural and Food Chemistry, scientists at University of Massachusetts, Amherst identify a novel approach to reduce toxic pesticide residues on conventional food. The method the authors describe is cumbersome and unlikely to be widely used by consumers. At the same time, study results confirm that eating organic products is the best way for individuals and families to eliminate pesticide residues from their diet. For the current study, researchers looked at how much of two common pesticides, one, the fungicide thiobendazole, and the other, the insecticide phosmet, remained on apples after submersion for 24 hours. Both pesticides penetrated the skin of the apples, though thiobendazole, a systemic fungicide, made its way deeper into and past the apple’s skin. Thiabendazole penetrated 80 micrometers into the apple while phosmet penetrated 20 micrometers. Researchers looked at three different methods to reduce the pesticides on apples: tap water, a bleach solution, and baking soda. Compared to the others, baking soda was found to be by far the most effective method to reduce pesticide residue, with 80% of thiabendazole and 95% of phosmet removed. “If factory washing [with bleach] is already effective, then […]

Neurotoxic Pesticide Detected in Air at High Levels in California County

Tuesday, August 29th, 2017

(Beyond Pesticides, August 29, 2017) Air monitoring in Kern County, California, finds levels of the highly neurotoxic pesticide, chlorpyrifos, in excess of the levels of concern established by the U.S. Environmental Protection Agency (EPA) for pregnant women. Chlorpyrifos is linked to low IQs, autism and other developmental neurological effects. Earlier this year, EPA Administrator Scott Pruitt refused to ban chlorpyrifos to the dismay of many scientists, medical professionals, and farmworker organizations. The California Department of Pesticide Regulation (CDPR) released its 2016 air monitoring data where it was revealed that chlorpyrifos air concentrations for a one-month period at the air monitoring site on the campus of Shafter High School in Kern County was 39.4 nanograms per cubic meter (ng/m3) – more than 18 times higher than EPA’s level of concern for pregnant women (2.1 ng/m3).  Shafter High School is some distance from fields in an area where chlorpyrifos use is not as high as in other parts of Kern County or elsewhere in California. More than 1.1 million pounds of chlorpyrifos was used in California in 2015, and more than a quarter of that is used in Kern County. High chlorpyrifos levels at a school means that children and unsuspecting teachers and […]

Ask Your Senators to Co-Sponsor Bill to Ban Chlorpyrifos, the Neurotoxic Pesticide that Harms Children—After EPA Reversal

Monday, August 14th, 2017

(Beyond Pesticides, August 14, 2017) Ask your U.S. Senators to co-sponsor legislation to ban the neurotoxic insecticide chlorpyrifos after the U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt reversed the previous administration’s proposal to discontinue its food uses. [The bill is currently co-sponsored by Senators Cory Booker (D-NJ), Ben Cardin (D-MD), Richard Durbin (D-IL), Kirsten Gillibrand (D-NY), Kamala Harris (D-CA), Ed Markey (D-MA), and Jeff Merkley (D-OR).] With EPA’s own assessment that the chemical is too toxic to children, it is time for Congress to intervene to get this highly toxic pesticide off the market. In March 2017, EPA Administrator Scott Pruitt reversed a 2015 proposal to revoke food residue tolerances of chlorpyrifos. A revocation of chlorpyrifos tolerances would have effectively banned the chemical from use in agriculture. Instead, Administrator Pruitt’s decision indicated the agency will continue to study chlorpyrifos and would not take any action until 2022. EPA’s assessment, which incorporates recommendations from a 2016 Scientific Advisory Panel (SAP), finds that children exposed to high levels of chlorpyrifos have developmental delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorders. The SAP agreed with EPA that there is an association between chlorpyrifos prenatal exposure and neurodevelopmental outcomes in children. In 2016, EPA concluded […]

National Academy of Sciences Urges EPA to Study Low Dose Endocrine Disruption

Monday, July 24th, 2017

(Beyond Pesticides, July 24, 2017) A new report by the National Academies of Sciences, Engineering, and Medicine (NAS) is recommending to the U.S. Environmental Protection Agency (EPA) a strategy to evaluate the evidence of adverse human health effects from low doses of exposure to chemicals that can disrupt the endocrine system. NAS believes that EPA’s current process, which utilizes traditional toxicity testing, would miss some effects that occur at doses lower then what EPA evaluates. EPA’s Endocrine Disruption Screening Program (EDSP) is currently screening chemicals for their potential to interact with the endocrine system, but the program is years behind schedule and has been criticized for using outdated methods. Endocrine disruptors are substances that can cause a variation in normal hormone function. Even small alterations in hormone concentrations, particularly during embryonic development and developmental phases of life, can have lasting and significant effects. Mounting science is showing that disruptions to the hormone system can occur at very low doses that according to NAS, are lower than those used in traditional toxicity testing by EPA. This means that some effects may be missed. EPA’s methodologies have been criticized over the years for failing to adequately capture impacts at low doses. EPA requested NAS […]
