(Beyond Pesticides, April 4, 2019) Contamination of drinking water with toxic breakdown products and risks to fish and and amphibians has led to a ban on the fungicide chlorothalonil in the European Union (EU). While the pesticide will be out of use in the EU next decade, tens of millions of pounds will continue to be sprayed throughout the U.S. unless regulators take action quickly. “The [chlorothalonil ban] is based on [the European Food Safety Authority’s] EFSA’s scientific assessment which concluded that the approval criteria do not seem to be satisfied for a wide range of reasons,” a spokeswoman for the European Commission told The Guardian. “Great concerns are raised in relation to contamination of groundwater by metabolites of the substance.” EFSA’s review of chlorothalonil categorized it as a 1B carcinogen, meaning it “may cause cancer,” with the most significant risk found for kidney cancer based on laboratory animal studies. Further research was needed into many of the metabolites (break-down substances) created when chlorothalonil degrades. However, regulators determined enough data was present to conclude that these breakdown substances may be genotoxic, with the potential to damage DNA and lead to cancer. European regulators also identified a high acute risk to […]

(Beyond Pesticides, April 2, 2019) The new documentary film “Ground War” will have its New York City premiere screening on Saturday, April 6, 2019, 7:30pm at Florence Gould Hall, 55 East 59th Street, New York, NY. The film is a moving depiction of a son’s quest for answers about the cause of his father’s cancer—which takes him into the world of doctors, scientists, pesticide regulators, victims of pesticide poisoning, activists, and land managers. The issue is exposure to pesticides used to manage lawns and playing fields and the father’s exposure as an avid golfer. The son, who is the filmmaker, finds others on the same search for answers because of harm or death of a loved one, then finds a solution in the work of activists and organic land managers. The film is particularly timely with public controversy about the use of the weed killer glyphosate (Roundup) and two lawsuits with multimillion dollar jury verdicts for compensation and punitive damages against its manufacturer, Monsanto (Bayer)—while thousands of lawsuits are pending. All of this widespread pesticide exposure is taking place in the face of inaction by the U.S. Environmental Protection Agency and headlines pointing to officials sidestepping the law. The film screening […]

(Beyond Pesticides, March 22, 2019) A two-year study, published March 14,  finds that field-relevant contamination with the neonicotinoid insecticide imidacloprid causes reduced body weight and metabolism in white-tailed deer, and – in fawns – mortality. Remarkably, researchers uncovered imidacloprid levels in free-ranging deer a full 3.5 times higher, on average, than the levels in the animals treated in their experiment. These new findings add to the mounting evidence of the hazards posed by current patterns of neonicotinoid use, while evidence of benefits remains sparse. The study, published in Nature Scientific Reports, includes two years of data on the physiological and behavioral outcomes of imidacloprid contamination in 80 white-tailed deer housed in a South Dakota State University captive research facility. Notably, researchers were unable to entirely control imidacloprid levels in untreated deer, most likely due to background contamination from corn- and soy-based feed, and surrounding vegetation infiltrated by runoff from nearby agricultural fields. This background contamination altered, but did not compromise, the analysis. Researchers found that imidacloprid levels detected in the spleens of treated and control animals were significantly predictive of reduced thyroid hormone levels, shorter jawbones, lower activity levels, and higher fawn mortality. Lead authors Elise Berheim, Jonathan Jenks, PhD, […]

(Beyond Pesticides, March 21, 2019) Corporate food giant General Mills has thrown some weight behind regenerative agriculture, committing to converting one million acres of farmland to regenerative practices by 2030. Some – but not all – of the initiative involves organic land management. Regenerative agriculture is a term with a range of interpretations, but the key element is improving soil health through carbon sequestration. Robert Rodale, one of the early proponents of organic agriculture and a major publisher, coined the name to characterize a process that moves beyond sustainable maintenance and into improvement of resources. This methodology is gaining traction in the farming world because it is economically beneficial to farmers and promotes environmental remediation. A 2018 study shows that ecologically-based farming systems have fewer pests and generate higher profits than their conventional counterparts. “Practitioners who have done this the longest point to the fact that in extreme years, their farms will do better than those who do not,” says Jerry Lynch, General Mills’ chief sustainability officer, “After some transition time, depending on their location and cropping system, farmers are saving a lot of money because they’re using fewer inputs.” In their press release, General Mills lays out three foci […]

(Beyond Pesticides, March 19, 2019) Research is beginning to explain how systemic neonicotinoid insecticides affect often overlooked species of ground nesting bees. While much of the current scientific literature has focused on the impacts of pesticides to bumblebees and honey bees, a study, Chronic contact with realistic soil concentrations of imidacloprid affects the mass, immature development speed, and adult longevity of solitary bees, recently published in Scientific Reports, confirms that wild, soil-dwelling bees are at similar risk. As policy makers consider ways to protect pollinators, this research finds that uncontaminated soil is an important aspect of ensuring the health of wild, native bees. “This is an important piece of work because it’s one of the first studies to look at realistic concentrations of pesticides that you would find in the soil as a route of exposure for bees,” said Nick Anderson, co-author of the study. “It’s a very under-explored route, especially for some of the more solitary species that nest in the ground.” In order to study the impact of neonicotinoids on ground nesting bees, researchers used orchard mason bees and leafcutter bees as proxies, as they are easier to gather and rear in the lab, and have a similar ecology […]

(Beyond Pesticides, March 14, 2019) A study, supported by the USDA’s National Institute of Food and Agriculture, finds that state pesticide preemption laws “compromise public health and economic well-being” by preventing localities from enacting pesticide use restrictions on private property that are more restrictive than their state’s regulations. In the words of the authors, “By eliminating the ability of local governments to enact ordinances to safeguard inhabitants from health risks posed by pesticides, state preemption laws denigrate public health protections.” The study, Anti-community state pesticide preemption laws prevent local governments from protecting people from harm, published in the International Journal of Agricultural Sustainability, reviews scientific and historical evidence of the failure of state and federal pesticide laws to protect localities from pesticide poisoning, and highlights the inability of localities to compensate for that failure under present laws. Communities seeking to protect their residents would typically issue community-wide restrictions to ensure protection of shared community resources, including air, land, and waterways, from pesticide drift, runoff, and other nontarget effects —as is the case with other community decisions on recycling, smoking, and zoning. The study’s authors document how industry influence led to the adoption of state laws that undermine the ability of localities […]

(Beyond Pesticides, March 13, 2019) A study on the impact of two neonicotinoid pesticides shows differential gene expression in bumblebees (Bombus terrestris) after exposure. Considering the current worldwide plight of insects, the authors of point to the cutting edge research as both a reason and a methodology to more carefully examine the effects of pesticides. “Caste- and pesticide-specific effects of neonicotinoid pesticide exposure on gene expression in bumblebees” was published in the journal Molecular Ecology in early March. Researchers fed variable colonies with clothianidin or imidacloprid-laced sucrose. They analyzed gene expression in the heads of worker bumblebees and colony queens using RNA sequencing (RNA-seq), inspired by biomedical techniques. This approach allowed for new insight on what genes and pathways are affected by neonicotinoid exposure. Study author Yannick Wurm, PhD, stated in a press release, “Our work demonstrates that the type of high-resolution molecular approach that has changed the way human diseases are researched and diagnosed, can also be applied to beneficial pollinators. This approach provides an unprecedented view of how bees are being affected by pesticides and works at large scale. It can fundamentally improve how we evaluate the toxicity of chemicals we put into nature.” Clothianidin had a stronger […]

(Beyond Pesticides, March 11, 2019)  We must stop the expanded commercialization of genetically engineered pesticides. The failure of the U.S. Environmental Protection Agency (EPA) to fully evaluate environmental impacts of gene-manipulating pesticides raises serious concerns in light of the agency’s ongoing failure to predict ecological effects of pesticides, such as the dramatic decline of pollinators. With the release of a 2019 peer-reviewed scientific article, Environmental Fate of RNA Interference Pesticides: Adsorption and Degradation of Double-Stranded RNA Molecules in Agricultural Soils, on the potential impact on soil and non-target microorganisms in soil, the study’s co-author, Kimberly Parker, PhD, remarked, “The ecological risk assessment of these emerging pesticides necessitates an understanding of the fate of dsRNA [double stranded RNA] molecules in receiving environments, among which agricultural soils are most important.” This technology, given that it is systemic to the plant and leaves traces in the soil, can cause widespread indiscriminate poisoning—as has been seen with bees, butterflies, birds, and the larger catastrophic decline of insect populations. Tell your members of Congress that the ecological effects of RNAi gene-manipulating pesticides raise serious questions—they have not been fully studied by EPA and, until they are, the agency should issue a moratorium on their release. Previously, […]

(Beyond Pesticides, March 7, 2019) A publication in the journal Environmental Health Perspectives highlights findings from a recent study showing that environmental concentrations of the neonicotinoid insecticides thiacloprid and imidacloprid increase expression of a gene linked to hormone-dependent breast cancer. Authors of the featured study uncovered a pathway through which neonicotinoids stimulate excess estrogen production, known to occur during the development of progressive hormone-dependent breast cancer. In the words of the authors, “Our findings highlight the need for further research to assess the potential impacts of low-dose and chronic exposure to neonicotinoids on endocrine processes affecting women’s health.” The study, published in Environmental Health Perspectives in April 2018 by researchers at the University of Quebec, is not the first to point to a potential link between neonicotinoid exposure and breast cancer. A 2015 study by the same research group revealed that the neonicotinoids thiacloprid and thiamethoxam, along with the herbicide atrazine, induce similar effects in breast cancer cells. In both studies, exposure to neonicotinoids alter promoter activity to induce heightened production of the enzyme aromatase, which is known to stimulate estrogen production and thereby cancer cell proliferation. The recently published study, authored by Silke Schmidt, PhD, brings greater urgency to […]

(Beyond Pesticides, March 4, 2019) Last week, U.S. Representative Earl Blumenauer (D-OR) reintroduced the Saving America’s Pollinators Act (H.R.1337) to cancel specific bee-toxic pesticides and establish a review and cancellation process for all pesticides that are potentially harmful to pollinators. The specific pesticides targeted in the bill include the systemic insecticides imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, sulfoxaflor, flupyradifurone, and fipronil. The bill also establishes requirements for review of other potentially bee-toxic chemicals by an independent pollinator protection board, and requires annual reports on the health and population status of pollinators. The bill creates a sustainable model for pollinator protection in the face of ongoing obstruction by an increasingly industry-influenced EPA. There are 29 cosponsors to date. The current bill is the fifth version of Saving America’s Pollinators Act (SAPA), which was first introduced by U.S. Representative Conyers (D-MI) in 2013. The newest version differs from previous bills in its bold definition of who should have responsibility for assessing harm to pollinators. SAPA 2019 calls for the establishment of a Pollinator Protection Board, to be composed of expert scientists, beekeepers, farmers, members of environmental organizations and other key stakeholders, nearly all of whom must not have any conflict of interest or affiliation […]

(Beyond Pesticides, February 26, 2019) Breakfast cereal, apples, applesauce and pinto beans made and sold by Kroger contain residues of toxic pesticides linked to a range of series health and environmental problems, according to a residue study by Friends of the Earth. This is alarming. Kid-friendly food like applesauce and Cheerios should not contain dangerous pesticides. Kids are the most vulnerable to these pesticides and shouldn’t be exposed to brain-damaging or cancer-causing pesticides when they eat their breakfast or snacks. The connection between pesticides and cancer, learning disabilities, and other diseases is supported by hundreds of studies in Beyond Pesticides’ Pesticide-Induced Diseases Database. These new tests, which corroborate numerous residue studies, mean that Kroger customers may be purchasing food with the intent of providing safe and healthy food for their families, but end up unknowingly exposing them to toxic pesticides. Join the national week of action by either delivering a letter to Kroger in person, or sending an email to Kroger Chief Executive Rodney McMullen. The pesticides found in Kroger’s food are harmful to human health and pollinators. Friends of the Earth found residues of cancer-causing glyphosate, brain-damaging organophosphates, and bee-killing neonicotinoid pesticides. Organophosphates can cause damage to children’s developing brains, including reduced IQ, loss […]

(Beyond Pesticides, February 21, 2019) In 2018, the Environmental Protection Agency (EPA) approved 16.2 million acres of crops to be sprayed with the bee-toxic insecticide sulfoxaflor under an emergency exemption. Sulfoxaflor was used in 18 different states on cotton and sorghum — plants known to attract bees. In response to a lawsuit headed by beekeepers, the EPA reclassified sulfoxaflor in 2016 and, recognizing its toxicity to bees, prohibited use on crops that draw in these pollinators. However, Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) gives the EPA authority to permit temporary emergency use of unapproved pesticides. This loophole is used regularly in response to predictable stressors. “Emergency” use was approved 78 times for sulfoxaflor on sorghum and cotton between 2012-2017. Sulfoxaflor is a systemic insecticide that acts similarly to neonicotinoid pesticides. After application, the chemical is absorbed and distributed throughout the plant, including pollen and nectar. These kinds of chemicals are selective agonists of insects’ nicotinic acetylcholine receptors—they bind to the receptor and cause it to activate. The impact on foraging bees is sublethal, but devastating on a population level. Even at low levels, sulfoxaflor impairs reproduction and reduces bumblebee colony size. Sufloxaflor is functionally identical to […]

(Beyond Pesticides, February 15, 2019) 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 — from Oakland, Minneapolis, Baltimore, and Atlanta — 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 “organic” days, and first thing on the morning after those six days. Fourteen different pesticides and metabolites were present in all participants’ urine in the “pre-organic” analysis; following the organic diet […]

(Beyond Pesticides, February 14, 2019) Over the course of the last two weeks in Bavaria – a southern state of Germany – locals rallied in an effort to save the bees. Braving the cold in eye-catching bee outfits, a broad coalition of activists collected over a million signatures (the necessary 10% of the state’s eligible voters) to move a petition into legislature. The petition pushes forward changes in farming practices to support pollinators; while bees are the charismatic champion of the campaign, changes will support biodiversity in general. Now that signatures are gathered, the state parliament has three months to handle citizens’ requests. Then, parliament can either accept the proposal as is or put it to a statewide referendum. In a statewide referendum, there will be a “yes” or “no” vote by a simple majority, with government bound by the result. A central motion within the petition is to increase percentage of organic farmland from 10% to 30% by 2030. This number is based on the global movement to conserve 30% of the world by 2030 in order to avoid environmental catastrophe. Proponents of the petition suggest that the demand for organic products is higher than current Bavarian capabilities, and that the […]

(Beyond Pesticides, February 13, 2019) Friends of the Earth (FOE) released a report last week again showing pesticide residues in the food supply. The report, Toxic Secret, found store and name brand foods produced and sold by the top four U.S. food retailers — Kroger (NYSE:KR), Walmart (NYSE: WMT), Costco (NYSE:COST) and Albertsons — contain residues of toxic pesticides linked to a range of serious health and environmental problems. Among the pesticides found is the herbicide glyphosate, confirming residue testing results found in numerous studies. Glyphosate, the active ingredient in Roundup, has has been detected in popular foods, including “100% pure” honey, Doritos, Oreos, Goldfish, Ritz Crackers, German beers, California wines, and UK bread. Glyphosate has been ranked as potentially cancer causing in humans and adversely affects the human gut microbiome. See Residue Testing Find More Glyphosate in Popular Cereals. The FOE study finds that oat cereals, apples, applesauce, spinach and pinto beans at the retailers contained detectable amounts of glyphosate, organophosphates and neonicotinoids. The average level of glyphosate found in cereal samples (360 parts per billion) was more than twice the level set by scientists at Environmental Working Group for lifetime cancer risk for children. The average level of glyphosate found in pinto beans (509 ppb) was more […]

(Beyond Pesticides, February 11, 2019) A new systematic review of insect population studies worldwide reports on “the dreadful state of insect biodiversity in the world, as almost half of the species are rapidly declining and a third are being threatened with extinction.” The study concludes with the dire prediction that insects as a whole will go extinct in the next few decades if patterns of intensive agriculture, in particular pesticide use, continue. The review, published in Biological Conservation, analyzes 73 insect population studies conducted within the past 40 years, filtered to include only those that quantitatively assess all insect species within a taxa over a span of 10 or more years. Researchers Francisco Sánchez-Bayo, PhD and Kris A.G. Wyckhuys, PhD uncover the disturbing truth behind this mass of data: one in every three insect species monitored worldwide is threatened with extinction. Even more concerning is the finding that 41% of insect species worldwide are in decline, outpacing the more well-publicized vertebrate declines by 200%. Only a few species are expanding in range or occupying vacant niches – not nearly enough to compensate for the massive losses. In 8% of the studies in the review, citizen science data is analyzed in […]

(Beyond Pesticides, February 8, 2019) Scientists from the U.S. Geological Survey (USGS) and the University of Iowa (UI) have published worrisome news on the neonicotinoid front. The experts discovered two metabolites of imidacloprid (a neonicotinoid insecticide) residues that had not previously been identified in drinking water — desnitro-imidacloprid and imidacloprid-urea. The researchers note both that these metabolites have never been evaluated for their potential risks to human and environmental health, and that there may be potential risks of anthropogenic compounds that can be created when water with neonicotinoid residues, and thus, these metabolites, undergo typical water treatment (often chlorination and/or pH treatment). They note that, “The mammalian toxicity of transformation products formed during water treatment processes remains unknown. It is possible that chlorination of neonicotinoids and their metabolites will . . . alter their bioactivity.” The joint, federally funded collaboration investigated neonicotinoid pesticides (“neonics”) in tap water to determine whether neonic metabolites are relevant to pesticide exposure through drinking water, and to identify any products of the chlorination of neonics and their metabolites. The scientists simulated realistic drinking water conditions in their research to demonstrate, in laboratory circumstances, that chlorinated disinfection byproduct chemicals are produced. The study, conducted by seven researchers […]

(Beyond Pesticides, February 7, 2019) A new study, released in Environmental Science and Policy, systematically reviews all state-level pollinator protection acts passed since 2000 and makes a somewhat dim diagnosis: as a rule, state policies fall far below the mark for protecting invaluable ecosystem services and ensuring long-term, sustainable food production. Authors judge the legislation against a set of pollinator protection policy benchmarks established in 2016 by a group of scientists from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Citing the ten policy recommendations laid out by IPBES experts, researchers point to the failure of all enacted state policies to address three main target areas – (1) to improve genetically modified crop risk assessment, (2) to incentivize farmers to make the switch from agrochemical dependence to sustainable benefits from ecosystem services, and, critically, (3) to support diversified farming systems. Beyond Pesticides notes one additional missed target: (4) funding for research on organic, diversified, and ecologically intensified farming. The study includes a total of 109 state laws passed from 2000 to 2017, which authors tracked down by searching usa.gov and state legislative websites and by submitting requests to state librarians. To uncover common themes and patterns among these […]

(Beyond Pesticides, February 4, 2019)  Although the rusty patched bumblebee was placed on the endangered species list in 2017, the Trump Administration has failed to put in place legally required safeguards for the species. The U.S. Department of the Interior (DOI) must designate locations where additional protections could help restore the endangered bumblebee’s population. Tell Your U.S. Representative and U.S. Senators to Urge U.S. Department of Interior Acting Secretary David Bernhardt to protect the endangered rusty patched bumblebee as required by law. DOI’s failure to comply with requirements under the Endangered Species Act (ESA) is consistent with the Trump Administration’s continued disregard for ongoing pollinator declines and environmental protections in general. Under ESA, DOI is required to determine “critical habitat” that contains physical and biological requirements a listed species needs in order to recover. That area must be designated within one year of placing a species on the endangered list, using best available scientific data. The Trump Administration’s DOI has failed to do so under either former Director Ryan Zinke or Acting Director David Bernhardt. Without determining critical habitat, the administration is in violation of the ESA, and the survival of a critical endangered species is threatened. The rusty patched bumblebee has a […]

(Beyond Pesticides, January 24, 2019) A UK Study has concluded that the expansion of community gardens, identified as “pollinator hotspots” with “high pollinator diversity,” offer an important opportunity for assisting ailing pollinator species and improving community quality of life, particularly in low income neighborhoods. Consequently, researchers suggest towns and cities can be planned and managed more effectively to steward existing urban biodiversity to create essential havens for pollinators and people under stress. The study finds that, “A high level of community robustness to species loss is increasingly recognized as an important goal in restoration ecology, since robust communities are better able to withstand perturbations.” As previous research has shown that organic agriculture boosts local economies, researchers account for and compare a key socioeconomic factor; household income. Affluent neighborhoods have larger, more numerous, and more consistently maintained gardens and green spaces. To increase city-scale robustness, researchers suggest increasing community garden allotments, planting perennial flowering plants in cemeteries, and improving management of public parks. However, researchers explain that increasing the number of community gardens, particularly in communities of low-income, would be the best strategy per unit area, as it would expand viable habitat for pollinators throughout cities while providing much-needed green space […]

(Beyond Pesticides, January 17, 2019) Although the rusty patched bumblebee was placed on the endangered species list in 2017, the Trump Administration has failed to put in place legally required safeguards for the species. As a result, the Natural Resources Defense Council (NRDC) is suing the Administration’s Department of the Interior (DOI) for failing to designate locations where additional protections could help restore the endangered bumblebee’s population. Advocates say DOI’s failure to comply with requirements under the Endangered Species Act (ESA) is consistent with the Trump Administration’s continued disregard for ongoing pollinator declines and environmental protections in general. Under ESA, DOI is required to determine “critical habitat” that contains physical and biological requirements a listed species needs in order to recover. That area must be designated within one year of placing a species on the endangered list, using best available scientific data. But the Trump Administration’s DOI, under both former Director Ryan Zinke and Acting Director David Bernhardt, has failed to do so, in violation of ESA. NRDC’s legal director Rebecca Riley notes that this lack of follow-through “leaves this highly endangered bee’s habitat at risk of destruction and decreases the species’ chance for survival.” The rusty patched bumblebee has […]

(Beyond Pesticides, January 16, 2019) Preliminary counts in California indicate the western monarch butterfly population dropped 86% from 2017 to 2018. The survey is a result of an annual effort by volunteer citizen scientists, organized by the nonprofit organization Xerces Society. If the trend from the initial sample (97 sites) holds true, the population of overwintering butterflies is estimated to be less than 30,000 – 0.05% of its historical size. Full and vetted results will be published in late January. To get an accurate count of monarch populations, volunteers follow a monitoring guide, which recommends beginning a count on a still, cool, and dry morning so that monarchs are still clustered together. Volunteers count a small cluster of monarchs and then extrapolate that number to arrive at a total for the larger cluster they’re observing. Citizen science has been crucial to understanding the decline of monarchs and insects worldwide. As covered by The New York Times, the current “Insect Apocalypse” has largely been documented by volunteers. The dismal numbers recorded this year are potentially disastrous, as the predicted extinction threshold for overwintering western monarchs is a population of 30,000. However this threshold, based on population densities needed for thermoregulation and mating […]

(Beyond Pesticides, January 9, 2019) It is news to approximately no one that pollinators are in trouble worldwide. A series of papers by biologists at the University of Guelph, Ontario, posits that pesticide regulations aimed at protection of honey bees fall far short of the critical task of protecting the multitude of bee species that are important pollinators of human food crops. These recent papers arose from 2017 workshops that involved 40 bee researchers from various universities, and representatives from Canadian, U.S., and European regulatory agencies, and from the agrochemical industry. Beset by shrinking habitat, pathogens, and toxic chemical exposures, bee pollinator populations are at great risk, even as “‘our dependency on insect-pollinated crops is increasing and will continue to do so as the global population rises,’ said [Professor Nigel] Raine, [PhD], [a] co-author of all three papers recently published in the journal Environmental Entomology. . . . Protecting wild pollinators is more important now than ever before. Honeybees alone simply cannot deliver the crop pollination services we need.” There are, in fact, more than 20,000 bee species worldwide, and 3,500–5,000 bee species in North America alone. Although regulators across many countries have focused narrowly on assessing the risk of pesticides to honey bees, many […]
