(Beyond Pesticides, September 8, 2022) A study published in Environmental Pollution finds parental exposure to real-world, sublethal concentrations of pesticide residues on grains is a major contributor to unfavorable offspring development among foraging birds. Parentsâ ingestion of grains with conventional pesticide residues, whether from contaminated or pesticide-treated seeds, results in chronic exposure that adversely affects offspring health, even at low doses. The adverse effects pesticides and other environmental pollutants have on birds are amply documented and researched. Although many studies evaluate acute or chronic health implications associated with pesticide exposure in a single generation, there is a lack of information on multi-generational impacts that can provide vital information on the fundamental survivability or fitness of bird species. Considering this study emphasizes parental exposure to environmental pollutants can have adverse consequences for future generations, it is necessary that future risk assessments for birds address these implications when implementing agricultural pesticide policies. The study notes, â[S]ublethal effects of such compounds [pesticides] on non-target species should be included in the regulation. Moreover, as agroecosystem pollution is not resulting only from pesticides, there is an urgent need to analyze cocktail effects, not only between molecules of pesticides but also between pesticides and other pollutants such as […]

(Beyond Pesticides, September 7, 2022) Neonicotinoid (neonic) insecticides are causing widespread contamination within deer populations in Minnesota, with recent data showing significant increases over sampling that took place just two years earlier. The Minnesota Department of Natural Resources (MDNR) began sampling the spleens of deer in the state after research conducted in South Dakota found widespread contamination, but also links to harmful effects as a result of the exposure. The latest findings will result in further testing, yet the sum of research on the dangers of neonicotinoids â not only to deer, but pollinators, birds, aquatic wildlife, and even human health â demands, according to advocates, a precautionary approach and meaningful restrictions on these potent systemic pesticides. Officials at MDNR have no explanation for the increase in contamination over the last sample period. “We’re not exactly sure why we saw that increase,” said Department of Natural Resources Ungulate Research Scientist Eric Michel, PhD, to mprnews.org. “But regardless, the two years of data are showing us that neonics are being detected pretty much across the state. When we look for them we find them in deer spleens. So that’s kind of the big takeaway from what we’re seeing right now.” Results […]

(Beyond Pesticides, August 30, 2022) Minuscule amounts of the weed killer Roundup and its active ingredient glyphosate can result in damage to the nervous system, finds research led by scientists at Florida Atlantic University, published in Scientific Reports. As hundreds of millions of pounds of glyphosate continue to be sprayed on hundreds of millions of acres of land throughout the United States each year, recent data indicate that four out of five U.S. children and adults contain detectable levels of glyphosate in their bodies. The pesticide industry and its paid supporters tell Americans that although contamination is widespread, the levels found in humans are not cause for concern. This latest research significantly undermines that specious argument, finding impacts on critical nervous system processes at levels 300 times less than the lowest suggested amount on the Roundup label. âIt is concerning how little we understand about the impact of glyphosate on the nervous system,â said Akshay S. Naraine, MSc., coauthor and a PhD student at Florida Atlantic University. âMore evidence is mounting for how prevalent exposure to glyphosate is, so this work hopefully pushes other researchers to expand on these findings and solidify where our concerns should be.â To investigate the […]

(Beyond Pesticides, August 25, 2022) A study published in World Journal of Pediatrics finds an association between antibiotic and neonicotinoid (neonic) exposure and onset of pediatric (childhood) type 1 diabetes (T1D) through effects on the gut microbiome. Individuals with type 1 diabetes are at higher risk of other autoimmune disorders, including thyroid and celiac disease. Ample evidence demonstrates environmental contaminants like pesticides and antibiotics negatively affect human mouth and gut microbes. Through the gut biome, pesticide exposure can enhance or exacerbate the adverse effects of additional environmental toxicants on the body. Moreover, studies find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects from metabolic/immune disorders to mental and physical disabilities. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Although studies show how chemical exposures affect overall human health, more research is now questioning how these toxic chemicals influence gut health and subsequent occurrence of diseases. In children, gut microbiome disruption, or gut dysbiosis, has significant associations with type 1 diabetes development, and disruption of gut microbiota plays a role in type 2 diabetes development. Over 11 percent (>37 million) of individuals in the U.S. have diabetes, and cases are growing by millions annually. With increasing rates of type 1 and […]

(Beyond Pesticides, August 23, 2022) Bees exposed to systemic insecticides become disoriented and cannot walk straight, showing evidence of brain damage in areas that coordinate movement, according to research published in Frontiers in Insect Science. Although scientific studies and regulatory determinations have already provided ample evidence implicating systemic insecticides like the neonicotinoids and sulfoxaflor with pollinator danger and decline, new research continues to fill in the remaining gaps. âHere we show that commonly used insecticides like sulfoxaflor and the neonicotinoid imidacloprid can profoundly impair the visually guided behavior of honey bees,â said lead author Rachel H Parkinson, PhD, a scientist at the University of Oxford. âOur results are reason for concern because the ability of bees to respond appropriately to visual information is crucial for their flight and navigation, and thus their survival.â Honey bees rely on landmarks, the direction of sunlight, and wide-field visual motion to orient themselves in a landscape, find nectar and pollen, and bring it back to the hive. While sunlight provides a compass, wide-field visual motion helps bees adjust speed and altitude, and determine where they are relative to known landmarks. Worker bees use this innate ability to reorient themselves to food or their hive […]

(Beyond Pesticides, August 16, 2022) Over half of all food samples tested by the U.S. Food and Drug Administration (FDA) contain the residues of at least one pesticide, and one in ten samples have levels that violate legal limits established by the U.S. Environmental Protection Agency (EPA). These findings, published by FDA this month in its 2020 Pesticide Residue Monitoring Report, are simply par for the course for government regulators, as FDA indicates the 2020 results âwere consistent with recent years.â However, while reporting on the dangerous pesticides present in U.S. food has become routine for FDA, more and more Americans are rejecting regular exposure to unnecessary toxics in their food by going organic with their food choices, planting their own pesticide-free gardens, and encouraging their elected officials to embrace safer, sustainable land care policies. Â FDA has conducted a review of pesticide residues on food on an annual basis since 1987, evaluating both domestic and imported foodstuffs into the US market. While EPA sets âpesticide tolerances,â also known as âmaximum residue levels,â of allowed pesticide residues on certain foods, FDA (and USDA, for some specific items like meat, poultry, and eggs) is tasked with enforcing these provisions. Pesticide tolerances, […]

(Beyond Pesticides, August 15, 2022)Â Senator Cory Booker (D-NJ) and seven other members of the United States Senate are calling on the U.S. Fish and Wildlife Service (FWS) to phase out the use of toxic pesticides in National Wildlife Refuges in order to protect declining wildlife species and the countryâs unique natural resources. The senators sent a letter to FWS Director Martha Williams urging FWS to âexpeditiously begin a rulemaking process to phase out the use of agricultural pesticides on National Wildlife Refuges.â The move comes at a time when native wildlife and the ecosystems humans rely upon are under greater threats than ever before from climate change, habitat destruction, and the indiscriminate use of toxic pesticides. Join eight U.S. Senators in calling for a phase out of the use of toxic pesticides in National Wildlife Refuges. âThe Refuge System was established to provide sanctuary for listed threatened and endangered species, migratory birds, and other wildlife,â wrote the senators in their letter. âThe Refugesâ migratory sanctuary and breeding grounds are especially critical for North American birds, as they have faced precipitous population declines; there are 3 billion fewer breeding birds in North America than there were in 1970. Unfortunately these birds […]

(Beyond Pesticides, August 8, 2022) The pesticide industry has selected August as Anti-Democracy Month, as it launches a month-long campaign to undermine local control over pesticides. The National Pest Management Association is encouraging members to lobby members of Congress in August to support H.R. 7266, to âprohibit local regulations relating to the sale, distribution, labeling, application, or use of any pesticide or deviceâ subject to state or federal regulation under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Beyond Pesticides urges you to make August Preserve Local Democracy Month by participating in actions in support of allowing communities to protect themselves from chemical exposure when state and federal regulation is inadequate. Tell your U.S. Representative and Senators to support communities by opposing H.R. 7266 and supporting the Protect Americaâs Children from Toxic Pesticides Act (PACTPA), which contains a provision affirming local authority to restrict pesticides. The fight to defend the authority of local governments to protect people and the environment has been ongoing for decades, reaching the U.S. Supreme Court in 1991. The Court specifically upheld the authority of local governments to restrict pesticides throughout their jurisdictions under federal pesticide law. In Wisconsin Public Intervenor v. Mortier, the Court ruled that federal […]

(Beyond Pesticides, July 12, 2022) More than four out of five U.S. children and adults over the age of six have detectable levels of glyphosate in their bodies, according to data recently published by the Centers for Disease Control and Prevention (CDC). With strong evidence implicating this chemical as a carcinogen, and emerging data associating it with adverse birth outcomes, the findings raise broad concerns for public health. As the U.S. Environmental Protection Agency (EPA) continues to permit widespread public exposure to toxic chemicals based on obscure economic arguments over the claimed benefits of pesticides, advocates say it is time for a change that embraces health and the environment over the profits of pesticide manufacturers. CDCâs testing data was developed as part of its National Health and Nutrition Examination Survey (NHANES), a long-running program that began in the early 1960s and has since become a continuous program focused on American health and nutrition measurements. Data from this program are subsequently analyzed to help inform the prevalence of disease in the U.S. population and are used to develop public health policies. A total of 2,310 urine samples retained from studies conducted in 2013-2014 were analyzed by NHANES researchers for the presence […]

(Beyond Pesticides, June 27, 2022) It is nowâmore than everâup to the Environmental Protection Agency (EPA) to recognize glyphosate (Roundup and other products) as a carcinogen and remove it from the market. As the Ninth Circuit Court of Appeals voided EPAâs âinterim registration reviewâ decision approving continued use of glyphosate, issued in early 2020 saying, âEPA did not adequately consider whether glyphosate causes cancer and shirked its duties under the Endangered Species Act (ESA),â and the Supreme Court refused to consider (deny certiorari) a Bayer petition to save the company from being held accountable to those diagnosed with cancer after using glyphosate herbicides, EPAâs failure to act speaks to the capture of the agency by the industry it is supposed to regulate. Tell the EPA to ban glyphosate immediately. Tell Congress to ensure that EPA performs its job as required by law. The Ninth Circuit court held that EPA unlawfully concluded that glyphosate does not pose a cancer risk. Despite overwhelming evidence and high profile lawsuits against Bayerâwith jury verdicts against the company in the tens of millions of dollarsâEPA came to âno conclusionâ on glyphosateâs connection to non-Hodgkin lymphoma (NHL). Notably, the agency did not assess how much glyphosate […]

(Beyond Pesticides, June 24, 2022) As reported by the Center for Food Safety (CFS), on June 16 the Environmental Protection Agency (EPA) released final Biological Evaluations, for three neonicotinoid insecticides, that indicate that these pesticides are âlikely to adversely affectâ the vast majority of endangered or threatened species and/or their designated critical habitats. These evaluations for imidacloprid, clothianidin, and thiamethoxam have been a long time coming, and represent, according to the Center for Biological Diversity (CBD), the first time EPA âhas completed biological evaluations of any neonicotinoidsâ harms to the nationâs most imperiled plants and animals.â These evaluations evidence what CFS, CBD, Beyond Pesticides, and others have maintained for years: that neonicotinoid compounds are very serious threats to the survival and well-being of myriad organisms and habitats. A Biological Evaluation (BE) is an EPA analysis of potential harmful impacts of a registered pesticide on any species federally listed, per the Endangered Species Act, as endangered or threatened, or on their critical habitats. EPA was legally required to issue the determinations by the June 2022 deadline, per CFS litigation and a subsequent 2019 legal settlement. EPA was the defendant in 2017 litigation brought by CFS, with Beyond Pesticides, several beekeepers, and the Center for Environmental […]

(Beyond Pesticides, June 23, 2022) In the first California statewide bumble bee census in 40 years, a University of CaliforniaâRiverside (UCR) study, published in Ecology and Evolution, reveals that once common bumble bee species in California are disappearing from the ecosystem. Wild pollinators like bumble bees provide pollination to billions of dollars worth of crops each year as these insects can flourish in cooler habitats and lower light levels than commercial honey bees. However, pollinators (such as bees, monarch butterflies, and bats) are a bellwether for environmental stress as individuals and as colonies. Both wild and commercial bees and other pollinators encounter multiple stressors, including pesticides, parasites, and poor nutrition, that act together to increase the risk of bee mortality. Therefore, studies like these highlight the need to establish monitoring and conservation frameworks incorporating varying habitats and species to assess fluctuations in biodiversity. The study notes, “Specifically, our study shows that greater monitoring of the diverse bumble bees of California is needed in order to better understand the drivers of biodiversity and decline in this genus, and to more effectively manage bumble bee conservation in the state.” Researchers compared data on bumble bee populations in California in 1980 and 2020. After collecting bumble […]

(Beyond Pesticides, June 22, 2022) Bad news is piling up for Bayer (Monsanto) and its carcinogenic flagship weed killer, glyphosate (Roundup). Last week, the Court of Appeals for the Ninth Circuit handed down a ruling that held the U.S. Environmental Protection Agencyâs (EPA) 2020 approval of its notorious weed killer glyphosate unlawful. Then, yesterday, the U.S. Supreme Court declined to consider (deny certiorari) Bayerâs âHail Maryâ petition attempt to save the company from being held accountable to those diagnosed with cancer after using Roundup (glyphosate) herbicides. In both cases, the courts are acting as a check on a company, while EPA regulators charged with stopping this behavior continue to rubber stamp the agrichemical industryâs dangerous decisions. This is not the first time that the Supreme Court has upheld the rights of victims of the pesticide industry. In 2004, Bates v. Dow Agrosciences (U.S. Supreme Court, No. 03-388), the court found: “The long history of tort litigation against manufacturers of poisonous substances adds force to the basic presumpÂtion against pre-emption. If Congress had intended to deprive injured parties of a long available form of compenÂsation, it surely would have expressed that intent more clearly. See Silkwood v. Kerr-McGee Corp., 464 U. […]

(Beyond Pesticides, June 21, 2022) June 20-24 is Pollinator Week, during which we recognizeâand take action to protectâthis important ecosystem link. Pollinatorsââbees, butterflies, birds, bats, and other organismsââmake a critical contribution to plant health, crop productivity, and the preservation of natural resources, but their existence is threatened by their pesticide-contaminated habitat. Pesticides have consistently been implicated as a key contributor to dramatic pollinator declines. Of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees. Honey bees alone pollinate 95 kinds of fruits, nuts and vegetables, such as apples, avocados, almonds, and cranberries. Take action to protect pollinators. Providing protection for pollinators also protects the ecosystem in which they live. That protection requires eliminating harm as well as providing safe habitats where they can live and reproduce. Provide organic habitat on your own property and encourage your town to go organic. Since plant starts in many garden centers across the country are grown from seeds coated with bee-toxic neonicotinoid pesticides, or drenched with them, Beyond Pesticides has compiled a comprehensive directory of companies and organizations that sell organic seeds and plants to the general public. Included in this directory are seeds for vegetables, flowers, and herbs, as well as […]

(Beyond Pesticides, June 9, 2022) A report from the Organic Center finds that people in U.S. BIPOC (Black, Indigenous, and People of Color) communities endure a significant disproportionate risk of exposure to pesticides and subsequent harms. The report also contains a lesson plan that informs young activists on how to improve the food system. Many communities of color and low-socioeconomic backgrounds experience an unequal number of hazards, including nearby toxic waste plants, garbage dumps, and other sources of environmental pollution and odors that lower the quality of life. Therefore, these populations experience greater exposure to harmful chemicals and suffer from health outcomes that affect their ability to learn and work. Doctoral candidate at Northwestern University and author of the report and lesson plan, Jayson Maurice Porter, notes, âUrban planning and city policy considers certain people in certain communities more or less disposable and puts them in harmâs way, giving them an uneven burden of experiencing and dealing with things like pollutants.â The father of environmental justice, Robert Bullard, Ph.D., defines environmental racism as any policy or practice that unequally affects or disadvantages individuals, groups, or communities based on their race. Dr. Bullard stated that, until the 1980s, environmentalism and pollution were separate. During the Jim […]

(Beyond Pesticides, June 7, 2022) Bumblebee colonies exposed to low levels of the weed killer glyphosate are unable to adequately regulate nest temperature, imperiling the next generation of bumblebees and long-term colony growth and survival. This latest finding, published this month in the journal Science, is a stark reminder that a pesticide does not have to kill an animal outright in order to create effects that ultimately result in death and population declines. “Sublethal effects, i.e. effects on organisms that are not lethal but can be seen, for example, in the animals’ physiology or behaviour, can have a significant negative impact and should be taken into account when pesticides are approved in future,” said Anja WeidenmĂźller, PhD, of the University of Konstanz, Germany. With regulators at the U.S. Environmental Protection Agency (EPA) refusing to adequately account for sublethal impacts, and myopically focused on the acute effects of pesticide exposure, bumblebee populations in the United States are in free fall and require urgent protective action. To better understand how glyphosate exposure affects bumblebee colony growth and brood (young larval bee) development, researchers first split colonies in two. One side of the colony was fed sugar water containing 5mg/liter of glyphosate, while […]

(Beyond Pesticides, May 23, 2022)  The climate change-induced increase in wildfire frequency and intensity has lent new urgency to efforts to manage so-called âinvasiveâ plants. Unfortunately, the herbicide-based approach favored by many is both counterproductive and hazardous. It must be replaced by an organic system, incorporating biological control agents like goats and establishing a more resilient ecology.  Tell your county/city officials to replace herbicides with organic vegetation management. Tell EPA and Congress that herbicides must be evaluated in the context of the availability of organic systems. Use of the herbicide indaziflam is an example of the ineffectiveness of management based on herbicides. While indaziflam is considered a âselectiveâ herbicide, it actually kills and prevents germination of a wide range of broad-leaved plants and grasses and comes close to being a soil sterilant. The action on seedlings is long-lasting, thus inhibiting the growth and establishment of a resilient plant community that is resistant to invasion. Given its persistence and nonselective action and the extent of the damage it causes to native soil seed banks and plant biodiversity, indaziflam could contribute to the eventual ecological collapse of ecosystems where itâs applied, similar to the cascading impacts of the systemic insecticides, fipronil and […]

(Beyond Pesticides, May 20, 2022)Â Beyond Pesticides has long covered the various ways in which corruption related to pesticides, agriculture, and food â whether in industry or government â can result in harm to human and environmental health, including to a multiplicity of organisms, and their ecosystems and habitats. In this Daily News Blog entry, we will review the landscape of U.S. pesticide regulation, examples of corruption, and what can be done to counter it. A look at some recent instances provides unfortunate assurance that problems of corruption at EPA persist. A serious flaw in EPAâs registration (and periodic pesticide registration review) processes is their reliance on industry-provided data and research on safety of pesticide products, which does not reliably represent actual risks of harms. Agrochemical companies sometimes purchase research that yields biased or distorted findings, cherry pick results in their submissions to EPA, or try to suppress research findings. USRTK recently covered an instance in which Bayer (and other companies) funded a study on the impacts â of use of their neonicotinoid (neonic) corn seed treatments â on bees during planting season. Neonics have been widely implicated in the plummeting health, function, and populations of pollinators and in the so-called […]

(Beyond Pesticides, May 9, 2022) While the U.S. Environmental Protection Agency (EPA) updated its guidelines for pollinator risk assessments in 2014, the agency continues to either fail to conduct full assessments, or dismiss concerning data it receives. EPA appears to discount threats like the insect apocalypse, evidenced by a 75% decline in insect abundance, which threatens not only global ecosystems, but also food production that depends on animal pollination. As pesticides move through the food web, birds are also at risk. Bird numbers are down 29% since Rachel Carson wrote Silent Spring in 1962. Tell EPA To Protect Against Other Threats to Pollinators. Tell Congress To Insist that EPA Does Its Job. The problem is highlighted by EPAâs recent Interim Decision on fenbuconazole, in which the agency notes that, âFor larval bees, RQs (risk quotients) exceed the LOC (level of concern) for all pollinator attractive uses including when assessed at the lowest application rate of 0.0938 lb a.i./Acre (RQ = 1.1).â Yet in the same document, the agency declares that ââŚthe benefits of fenbuconazole (e.g., efficacy in management of fungal pathogens) outweigh any remaining risk and that continuing to register fenbuconazole provides significant benefits, including its ability to increase crop […]

(Beyond Pesticides, May 5, 2022) A report published in Biological Conservation finds environmental pollutants, including pesticides, pharmaceuticals, plastics, and particulate matter, adversely affect tropical terrestrial wildlife. Specifically, these contaminants can interact with one another, altering the chemical landscape of the ecosystem, and causing changes in the endocrine and microbiome systems of mammals. Since the publication of Rachel Carsonâs Silent Spring (1962), global attention to the danger of pesticides has increased, with environmental agencies banning the use of legacy pesticides like organochlorines for their devastating toxicâsometimes lethalâeffects. However, these chemicals can remain in the environment for decades and interact with various current-use pesticides, including organophosphates, neonicotinoids, and pyrethroids. Although many studies demonstrate that environmental pollution plays a significant role in premature deaths among humans, there is a lack of research on how environmental pollution directly affects tropical species mortality. Considering human and wildlife habitats tend to overlap, and chemical pollutants can drift from chemically treated areas, wildlife populations are more likely to experience similar health effects. With the number of chemicals in the ecosystem growing, studies like these highlight the need for pesticide policies that protect human health in addition to the integrity of the chemical landscapes accommodating wildlife. The researchers note, âUsing […]

(Beyond Pesticides, April 27, 2022) Pesticides can accumulate in aquatic fly larvae, be retained through metamorphosis, and represent a source of chronic pesticide exposure to birds and bats, according to research published in Environmental Science and Technology earlier this month. As population declines among these critical wildlife continue to mount, findings like these highlight the complex ways in which human activities are further stressing natural systems. Pesticide reviews conducted by the U.S. Environmental Protection Agency (EPA) are limited to an outdated set of studies conducted by the pesticide industry, and generally reject and dismiss emerging science from independent literature. This myopic focus on industry studies has brought widespread contamination to the natural world that necessitates wholescale changes at EPA through Congressional action. With widespread acknowledgement that older pesticide chemistries, such as organochlorines like DDT and aldrin, bioconcentrate in living organisms, researchers aimed their study at present use fungicides and herbicides that have not yet undergone similar scrutiny. This includes seven fungicidesâazoxystrobin, boscalid, cyflufenamid, fluopyram, tebuconazole, pyrimethanil, and trifloxystrobinâand two herbicidesânapropamide and propyzamide. The study notes that formulated end use products, rather than technical grade active ingredients, were used in order to best mimic real world exposure conditions. Larvae of the […]

(Beyond Pesticides, April 21, 2022) A literature review published in Royal Society finds that âinertâ ingredientsâ in pesticide formulations adversely affect the health of bees and other wild pollinators. Inert ingredients, also known as âotherâ ingredients, and not disclosed by name on pesticide product labels, facilitate the action of active ingredients targeting a specific pest. Although both ingredients have chemical and biological activity, most studies on agricultural chemical toxicity focus on the active ingredient, assuming that inert ingredients are ânontoxic.â The U.S. Environmental Protection Agency (EPA), in regulating pesticides, assesses the toxicity of individual active ingredients on bees through various testing methods. However, there are no requirements for EPA to test inert ingredients to the same degree, despite evidence demonstrating these chemicals harm pollinators. Moreover, EPA does not require pesticide manufacturers to disclose the inert ingredients used in any product as the information is confidential. Both wild and commercial bees and other pollinators encounter multiple stressors, including pesticides, parasites, and poor nutrition, that act together to increase the risk of bee mortality. Therefore, reviews like these highlight the need for pesticide testing to consider the effects of all product ingredients, regardless of perceived toxicity. The researchers caution, âWe argue that âinertâ ingredients […]
