(Beyond Pesticides, February 13, 2020) Congress unanimously passed the Food Quality Protection Act (FQPA) in 1996 to increase protections for children from pesticide exposure. Unfortunately, according to a new study published in Environmental Health, the law is not being employed by the Environmental Protection Agency (EPA) to its full capacity. For most of the 59 pesticides reviewed by the study, EPA did not apply an additional FQPA safety factor and thereby missed an opportunity to protect children’s health. In fact, FQPA solidified EPA’s reliance on risk assessment calculations and mitigation measures that consistently fall short of adequate levels of protection because of serious data gaps, a failure to consider exposure to mixtures and synergistic effects, and a bias against consideration of alternatives (alternatives assessment)  that show toxic pesticides to be unnecessary.  FQPA establishes a safety standard applied to all food commodities that considers specific risks for infants and children. The law requires EPA to assess the “aggregate risk” (considering exposure from multiple sources) and “cumulative exposure” to pesticides that have a “common mechanism of toxicity.” FQPA mandates “an additional tenfold margin of safety for the pesticide chemical residue and other sources of exposure shall be applied for infants and children […]

(Beyond Pesticides, February 7, 2020) Toxic pesticide use in New York City (NYC) parks would get the boot if a bill — Intro 1524 — being considered by the New York City Council passes. The bill “would ban all city agencies from spraying highly toxic pesticides, such as glyphosate (Roundup), and be the most far-reaching legislation to implement pesticide-free land practices in New York City parks,” according to a press release from its sponsors, New York City Council members Ben Kallos and Carlina Rivera. The January 29 hearing on the bill in the council’s Committee on Health was preceded by release of an important report from The Black Institute: Poison Parks, which calls out the NYC Parks Department for, in particular, its continued use of glyphosate-based herbicides. It also notes, “Minority and low-income communities suffer from the use of this chemical and have become victims of environmental racism.” NYC Council members Kallos and Rivera point out, in their joint press release, that Roundup is the pesticide most intensively used by city agencies, and that, “The use of this pesticide poses a health risk for anyone who frequents city parks and playgrounds, as well as, city workers, including city parks employees […]

(Beyond Pesticides, February 4, 2020) It was a good day for Bayer/Monsanto. The chemical company’s weed killer glyphosate and its neonicotinoid insecticides are set for reapproval by the U.S. Environmental Protection Agency (EPA), according to interim decisions published last week. EPA reapproval of human carcinogens and chemicals contributing to the pollinator crisis is disappointing for health and environmental advocates, but not surprising to those watchdogging the agency during the current administration. “This is how a captured agency behaves,” said Beyond Pesticides community resource and policy director Drew Toher. “When EPA’s decision making repeatedly reflects the exact wishes of the chemical industry, public trust erodes, and we must look to new policy mechanisms that support the protection of health and the environment.”   On Glyphosate EPA’s glyphosate decision document glosses over the hazards of the chemical and is requiring very few new safety measures when using the herbicide. These measures are focused on agriculture, including minor label changes around drift, guidelines on resistance management, and a label advisory indicating the chemical is toxic to plants and may adversely impact pollinator foraging. The restrictions fail to match those proposed by Health Canada in 2015, which included buffer zones and restricted entry intervals. […]

(Beyond Pesticides, January 31, 2020) In the latest of a long litany of destructive decisions by the Trump administration, U.S. Environmental Protection Agency (EPA) Administrator Andrew Wheeler announced on January 23 the establishment of a new weaker federal rule on protection of U.S. waterways, which replaces the 2015 Waters of the United States (WOTUS) rule that the agency repealed in September 2019. In an obeisant gesture to industrial interests — the agrichemical, construction, and mining sectors — Mr. Wheeler chose to announce the replacement rule, the Navigable Waters Protection Rule, at a Las Vegas National Association of Home Builders International Builders’ Show. This decision will significantly weaken protections by drastically reducing the number of U.S. waterways and acreage of wetlands protected, and by jettisoning proscriptions on activities that threaten waterways from a variety of pollution harms. President Obama’s WOTUS, aka Clean Water Rule, has provided protections from pesticide runoff and other pollutants to millions of acres of wetlands and thousands of miles of streams. According to Administrator Wheeler, “‘All states have their own protections for waters within their borders, and many regulate more broadly than the federal government. . . . Our new rule recognizes this relationship and strikes the proper […]

(Beyond Pesticides, January 28, 2020) In more bad news from the insect world, recent research reveals a precipitous decline in numbers of mayflies in territories where they have been historically abundant. Reported by National Geographic and published in the Proceedings of the National Academy of Sciences, the research finds that in the Northern Mississippi River Basin, seasonal emergence of burrowing mayfly (genus Hexagenia) adults declined by 52% from 2012 to 2019; in the Western Lake Erie Basin, from 2015 to 2019, the reduction was a shocking 84%. Neonicotinoid insecticides are a significant factor in this decline because mayflies are exquisitely vulnerable to their impacts, even at very low exposure levels. Ephemeroptera to entomologists — and “mayflies” to the rest of us — are a keystone species, one on which other species in an ecosystem are very dependent, and without which, the ecosystem would undergo drastic change. The Latinate name is apt: mayflies are among the most short-lived organisms, with lifespans across the 2,000+ known species lasting from five minutes to one day to a few weeks. Like damselflies and dragonflies, members of an ancient group of insects, the 600 North American species, as do their global kin, make optimal reproductive […]

(Beyond Pesticides, January 17, 2020) In Brussels, the European Commission (EC) has just decided not to renew approval of the neonicotinoid pesticide thiacloprid, citing both environmental and health concerns related to use of and exposure to the pesticide. The decision was approved by a majority of European Union (EU) governments last fall, after the EC had made the proposal to them. The EC based that proposal on findings of the European Food Safety Authority (EFSA) published in January 2019, which highlighted concerns about toxicity to humans and high concentrations in groundwater. European Commissioner for Health and Food Safety Stella Kyriakides commented, “There are environmental concerns related to the use of this pesticide, particularly its impact on groundwater, but also related to human health, in reproductive toxicity.” The current EU use approval for thiacloprid products expires on April 30, 2020. The EC decision — functionally, a ban — means that farmers will need to turn to other means to deal with the primary thiacloprid targets in agriculture, aphids and whiteflies. Beyond Pesticides and many organic agricultural resources advocate for widespread adoption of organic, regenerative systems and practices. Such systems may include management features such as mechanical and biological controls, trap crops, natural […]

(Beyond Pesticides, January 14, 2020) Scientists have found a new method to reduce the sources of Lyme disease, but it is uncertain whether the finding will ultimately translate into fewer cases of human infections. Research published in the journal Experimental and Applied Acarology finds that incorporating Lyme vaccines into pelletized mouse food had the effect of reducing levels of Borrelia burgdorferi, the bacterium that causes Lyme disease, in both mice and ticks in a certain location. “So, the idea here is to vaccinate the mice,” study author Kirby Stafford, PhD told WBUR. “What we’ve done is incorporate a Lyme disease vaccine in an oral bait that would immunize them. That would prevent ticks feeding on those animals from becoming infected and then ultimately turn around and infect you.” To test their approach, researchers enrolled 32 homes in Redding, CT, an area where Lyme disease in endemic and several human cases are reported each year. Vaccine-incorporated mouse baiting stations were placed around 21 homes, while 11 acted as a control. Four times throughout the two year study period, mice and the ticks attached to them were trapped and tested for the disease. While there were no significant differences between the experimental […]

(Beyond Pesticides, January 10, 2020) A new study by researchers out of the University of Iowa College of Public Health, published in JAMA (the Journal of the American Medical Association) Internal Medicine, demonstrates that greater exposure to pyrethroid insecticides is associated with higher risks of death from all causes and from cardiovascular disease. These compounds can be inhaled, ingested, or absorbed through the skin; they are highly neurotoxic, and have also been linked to certain cancers, endocrine disruption, and suppression of the immune system, as well as respiratory and reproductive impacts. The researchers gathered data, for 2,116 adults aged 20 or older, from the National Health and Nutrition Examination Survey. Each of those subjects had contributed a urine sample at some point between 1999 and 2002. Urine samples reflect levels of a pyrethroid metabolite (3-phenoxybenzoic acid) present, which in turn offer information about pyrethroid exposure. The researchers followed the participants until 2015; the research analysis was performed in the summer of 2019. Data were adjusted to accommodate multiple factors (age, sex, ethnicity, socioeconomic status, diet and lifestyle, smoking status, body mass index, and urinary creatinine levels). The co-authors report that subjects with the highest levels of metabolites had a 56% […]

(Beyond Pesticides, December 5, 2019) Five years after three neonicotinoids were banned for use on bee-attractive crops in the EU, researchers found that these bee-toxic chemicals are contaminating soils and poisoning the nectar of oilseed rape (canola). The results of this research point to an immediate need to end the use of persistent environmental contaminants and promote organic practices. Researchers set out to determine whether the EU moratorium eliminated the risk for bees that forage on oilseed rape nectar. They tested for imidacloprid, thiamethoxam, and clothianidin residues in the nectar of winter-sown oilseed rape in from 291 oilseed rape fields in western France for five years following the EU moratorium (2014-2018). Results show all three neonicotinoids were present at least once in the study’s time period. Imidacloprid was detected every year with “no clear declining trend,” though its prevalence fluctuated widely between years. Two samples from 2016 show residues that are five times the expected maximum concentration in nectar of a plant directly treated with imidacloprid. Residue levels in the nectar depend on soil type and increase with rainfall. The researchers put forth in their discussion that the imidacloprid contamination may likely be caused by runoff from neighboring, treated plants. […]

(Beyond Pesticides, November 25, 2019) Continuing its marathon of deregulation to benefit the chemical industry, the Trump administration’s Environmental Protection Agency (EPA) announced its proposal to increase the amount of the weed killer atrazine allowed in U.S. waterways by 50% during the chemical’s registration review—a stark reversal of previous proposals to significantly reduce atrazine levels in the environment. The atrazine proposal follows closely on the heels of a proposal to further weaken protections regarding 23 pyrethroid insecticides that have been repeatedly linked by peer-reviewed studies to neurological issues such as learning disabilities in children. Ask Congress to request an investigation into whether EPA is ignoring its statutory duty and regulatory requirements to use science in its proposals. EPA’s atrazine proposal comes after agrichemical giant Syngenta and the National Corn Growers Association requested that EPA dismiss independent research regarding the adverse impact of atrazine. Atrazine, a broadleaf herbicide, is linked to endocrine disruption, neuropathy, and cancer. It disrupts the sexual development of frogs at levels far below the current allowed concentrations by EPA. Studies by Tyrone Hayes, PhD, University of California, Berkeley, and others have shown that concentrations as low as 0.1 ppb turn tadpoles into hermaphrodites. A 2009 study linked birth defects like gastroschisis and choanal atresia to the relative concentrations of atrazine and other pesticides […]

(Beyond Pesticides, November 20, 2019) Continuing its marathon of deregulation to benefit the chemical industry, the Trump administration’s Environmental Protection Agency (EPA) released a memo announcing its proposal to increase the amount of the weed killer atrazine allowed in U.S. waterways by 50% during the chemical’s registration review—a stark reversal of previous proposals to significantly reduce atrazine levels in the environment. The proposal comes after agrichemical giant Syngenta and the National Corn Growers Association requested that EPA dismiss independent research regarding the adverse impact of atrazine.  Atrazine, a broadleaf herbicide, is linked to endocrine disruption, neuropathy, and cancer. It disrupts the sexual development of frogs at levels far below the current allowed concentrations by EPA. Studies by Tyrone Hayes, Ph.D., University of California, Berkeley, and others have shown that concentrations as low as 0.1ppb interfere with mammary gland development in the breast of mammals. In 2009, a study linked birth defects like gastroschisis and choanal atresia to time of conception and the relative concentrations of atrazine and other pesticides in drinking water. The current Concentration Equivalent Level of Concern (CELOC), a measure in place to protect aquatic organisms, for atrazine is a 60-day average concentration of 10 ppb. EPA’s proposal […]

(Beyond Pesticides, November 14, 2019) The Environmental Protection Agency (EPA), under pressure from chemical companies, released a proposal on Tuesday to further weaken protections regarding 23 pyrethroids. Pyrethroids are a common class of neurotoxic insecticides that have been repeatedly linked by peer-reviewed studies to neurological issues such as learning disabilities in children. They are also extremely damaging to non-target invertebrates, according to EPA’s own analysis. Despite this, EPA had already recently undermined protections for children from these chemicals, and the Trump Administration is now embracing industry proposals to further remove other safety barriers to human health and the environment. The Pyrethroid Working Group, a weighty working group of pesticide companies, requested EPA reduce safeguards such as a permanent 66-foot vegetation buffer between fields and water bodies to a 10 – 25-foot buffer. Also, the working group (and now EPA) suggests that the wind-speed cutoff for spraying should be increased from 10 mph to 15 mph. EPA’s announcement proposes the reapproval of five out the 23 pyrethroids; proposals regarding the rest are already pending approval. EPA is accepting public comments on the proposal until January 13, 2020. As mentioned, this is only the latest detrimental decision EPA has put forth regarding […]

(Beyond Pesticides, October 31, 2019) Last week the U.S. District Court in San Francisco ruled that the Environmental Protection Agency (EPA) must assess the risk eight toxic pesticides pose to protected organisms: atrazine, carbaryl, methomyl, and simazine as well as rodenticides brodifacoum, bromadiolone, warfarin and zinc phosphide. The plaintiffs, Center for Biological Diversity (CBD) and Pesticide Action Network North America (PANNA) asserted that EPA and its then administrator Scott Pruitt violated duties under the Endangered Species Act (ESA) by not consulting with the Fish and Wildlife Service and National Marine Fisheries Service in registering these pesticides. The history of this case extends over 8 years. Last year, the court rejected EPA’s attempts to dismiss the lawsuit. According to CBD’s press release, “Under the agreement the agency must complete assessments of four pesticides, including atrazine, the nation’s second most-used pesticide, by 2021. Assessments of four rodenticides, including the widely used rat poison brodifacoum, must be finalized in 2024.” Stephanie Parent, an attorney at the Center for Biological Diversity, said “This important step is only the start. We still have work to do to make sure the EPA addresses the harms of all pesticides, as the law requires. EPA was created after […]

(Beyond Pesticides, October 25, 2019) Washington State officials have approved an agreement that will prevent oyster growers farming in Willapa Bay and Grays Harbor from spraying the neonicotinoid (neonic) insecticide, imidacloprid, on tidal flats to kill native burrowing shrimp. The development comes after years of discussion and dispute among the Washington State Department of Ecology, the National Marine Fisheries Service, and the Willapa Grays Harbor Oyster Growers Association. Beyond Pesticides has advocated for protection of these relatively pristine estuary areas from toxic pesticides since 2002, when it worked for (ultimately successful) elimination of the use of the highly toxic carbaryl against the shrimp. More recently, it has reported and weighed in frequently on use of imidacloprid and efforts to eliminate its use, as well as on broad contamination of waterways by neonics. Neonics are well documented to be a huge threat to pollinators and other nontarget organisms, as well as to the environment at large. Imidacloprid is banned by the European Union for outdoor use, and Canada is scheduled to announce details by year’s end on its implementation of a phaseout of neonics. Washington State’s own risk assessment study found that use of imidacloprid on tidelands showed “immediate adverse, unavoidable […]

(Beyond Pesticides, October 15, 2019) EPA is requesting comment on its proposal to require data that will help it determine synergistic effects of some pesticides. EPA has received on a pressure on a number of fronts, including a report by the Center for Biological Diversity, a report by its own Inspector General, a letter from 35 Congressional Representatives, and research pointing to the unavoidability of synergistic effects—the chemical combinations that cause greater effects when mixed together than the sum of the individual chemical effects. Despite all of the evidence that synergism is the rule rather than the exception, EPA’s consideration focuses on a narrow range of cases in which pesticide product patents make claims of synergy. Tell EPA to always investigate synergy and to determine need for pesticides. One such product is Dow’s Enlist Duo, which combines glyphosate and 2,4-D in an attempt to overcome weed resistance. The focus on products and tank mixes where synergism is a selling point brings to light the fact that as a rule, EPA does not request efficacy data in registering pesticides not intended to protect public health. Thus, although required by law to weigh pesticide risks and benefits, EPA rarely has data to make […]

(Beyond Pesticides, October 11, 2019) The Office of Pesticide Programs (OPP) of the U.S. Environmental Protection Agency (EPA) is seeking public comment on a document that describes an “interim process” being used to assess potential synergistic effects of admixtures of pesticide active ingredients on non-target organisms. This interim risk assessment process was catalyzed in part by a 2015 lawsuit brought by a group of non-governmental organizations; that suit cited EPA’s failure to evaluate appropriately the impacts of a new herbicide, Enlist Duo, on non-target species, including some endangered species. EPA’s inattention to synergistic impacts on non-target species has long been a deficiency of EPA’s pesticide review and regulation and a focus for Beyond Pesticides’ work to factor in uncertainties, or unknowns, in registering pesticides under a precautionary approach. Although EPA recognizes that pesticide exposures occur in combinations, it evaluates a very limited number of such interactions. Manufactured by Dow AgroSciences, Enlist Duo combines glyphosate and 2,4-D. Increasingly, manufacturers create and market such “twofer” products as responses to the burgeoning issue of plant resistance to individual pesticides. As insects, fungi, weeds, or other “pests” inevitably develop resistance to pesticide, herbicide, fungicide, or insecticide compounds, the efficacy of the chemical treatment obviously plummets. […]

(Beyond Pesticides, October 2, 2019) New data gleaned from the Kuakini Honolulu Heart Program — a longitudinal study of men of Japanese descent living on Oahu — demonstrate that occupational exposure to high levels of pesticides can increase risks for cardiovascular disease (CVD) in the forms of coronary heart disease (CHD) or stroke (CVA, or cerebrovascular accident). Further, researchers determined both that workers who experience high-level exposures may not experience such effects for years afterward, and that the maximum subsequent effects were seen within a decade of exposure. The study’s conclusion highlights the importance of pesticide applicator use of protective gear when handling toxic pesticides. These risks and harms could be eliminated through a transition to non-chemical means for pest control in agriculture, land management, and home and personal practices. The Kuakini Honolulu Heart Program, after enrolling more than 8,000 Japanese-American men, 45–68 years old and living on Oahu, Hawaii between 1965 and 1968, has continued to examine and interview these subjects, and document morbidity and mortality among them. This study, which performed statistical analyses on 7,557 of the subjects, is the longest longitudinal study of cardiovascular disease and any association with chronic occupational pesticide exposure, taking into account epidemiologic risk […]

(Beyond Pesticides, October 1, 2019) Commonly used fungicides induce trophic cascades that can lead to the overgrowth of algae, according to research published in the journal Chemosphere. While the current process for regulating pesticides in the U.S. focuses on the acute toxicity of pesticides, and may consider some chronic impacts, real world complexities as described in the current study are not reviewed. This gap in our assessment can lead to significant adverse effects not just on individual species, but entire ecosystems. Researchers investigated how fungal parasites known as chytrids control the growth of phytoplankton. While some strains of chytrids are notorious for their impact to frog species, some do in fact provide important stopgaps within ecosystems. “By infecting cyanobacteria, parasitic fungi limit their growth and thus reduce the occurrence and intensity of toxic algal blooms,” says IGB researcher Ramsy Agha, PhD, co-author the study. “Whereas we usually perceive disease as a negative phenomenon, parasites are very important for the normal functioning of aquatic ecosystems and can — as in this case — also have positive effects. Pollution by fungicides can interfere with this natural process,” the researcher adds. The agricultural fungicides tebuconazole and azoxystrobin were tested on chytrid-infected toxic bloom-forming […]

(Beyond Pesticides, September 24, 2019) In 2016, Canadians and Americans residing in Havana reported symptoms of headaches, dizziness, nausea. They described hearing strange buzzing and high-pitched sounds – some woke in the middle of the night fumbling for alarm clocks that were not going off. Media used the term “Havana syndrome” to describe the illness. Diplomats, scared by symptoms that seemed to only hit them in their hotel rooms or at home, speculated that a sonic weapon was being used against them. The Trump administration accused Cuban leaders of misconduct and removed all but essential employees. Later, some suspected that the diplomats could have experienced “mass hysteria.” A new Canadian study provides a more likely explanation to this mysterious illness that impacted diplomats in Havana: neurotoxic pesticide exposure. Researchers conducted testing on 14 individuals who had resided in Havana and a control group of 12 that had never lived there. Some of the experimental group had been recently exposed while others, tested 19 months after their return, were classified as “remotely exposed.” Tests included brain imaging and self-reported symptom questionnaires. They analyzed blood samples for routine biochemistry, kidney, liver, and metabolic functions. Individuals that showed symptoms of brain injury went […]

(Beyond Pesticides, September 20, 2019) The actual utility of pesticides to achieve their purported goals is an under-recognized failing of the regulatory review of pesticide compounds for use. A study published in Scientific Reports now exposes the faulty assumptions underlying the use of neonicotinoids — the most widely used category of insecticides worldwide. The study demonstrates that use of neonicotinoids (neonics) to treat seeds — a very common use of these pesticides — actually provides negligible benefits to soybean farmers in terms of yield and overall economic benefit. The U.S. Environmental Protection Agency (EPA) should take notice, and consider that efficacy ought to have a role in the agency’s evaluation of pesticides for registration. Neonicotinoids are systemic pesticides that move through a plant’s vascular system and are expressed in pollen, nectar, and guttation droplets (drops of sap exuded on the tips or edges of leaves of some vascular plants). They can also persist in the environment — in soil and water — for extended periods. Neonics are applied to seed, as well as to crop soils and to plant foliage. Corn and soybean seed treatments represent the largest uses of neonics in the U.S.: for somewhere between 34% and 50+% […]

(Beyond Pesticides, September 17, 2019) The poisonous farm fields migratory birds forage on during their journey reduce their weight, delay their travel, and ultimately jeopardize their survival, according to new research published in the journal Science.  Like their effects on pollinator populations, neonicotinoid insecticides generally are not killing migratory songbirds outright, but instead precipitating a cascade of sublethal impacts that reduces their fitness in the wild. As the authors told Environmental Health News, the study is a call not simply to ban neonics or one class of chemical, but to change the entire farming system toward more sustainable bird and bee-friendly practices. Using new technology, this study was not only able to dose wild-caught songbirds (white-crowned sparrows), but also track their migration route using automated telemetry. Apart from the control group that received no pesticide exposure, sparrows were treated at levels well below the median lethal dose (3% of the lethal dose in the ‘low’ exposure group and 10% within the ‘high’ exposure group), and permitted to continue on their migratory path. These are exposure amounts similar to a songbird accidentally ingesting a few treated seeds, according to the study. Within six hours, both the ‘low’ and ‘high’ exposure group […]
