Hazardous Fumigant in Food Production Harmful to Farmworkers, Groups Call for Ban

(Beyond Pesticides, January 3, 2023) The California Department of Pesticide Regulation (DPR) announced new rules that remove existing limits on the use of 1,3-dichloropropene (1,3-D or Telone), allowing Californians to breathe much more 1,3-D than state toxicologists in the Office of Environmental Health Hazard Assessment (OEHHA) say is safe and highlighting the dangers to which farmworkers are routinely exposed. It is outrageous that the state of California and the U.S. Environmental Protection Agency (EPA) would allow farmworkers—whose labor was judged “essential” during the pandemic—to be routinely exposed to highly toxic pesticides, which could be replaced by organic practices. While the state of California describes its action as increasing protection, advocates point to continued use, unacceptable harm, and the availability of alternative organic agricultural production methods that eliminate the use of 1,3-D. Since over a third of the country’s vegetables and three-quarters of the country’s fruits and nuts are grown in California, most people who buy their food in a grocery store have a stake in how food is grown in the state and the impact that it has on those who live and work there. Tell the state of California, U.S. EPA, an the U.S. Congress to cancel the registration […]

Survey Technique Increases Agricultural Resiliency and Protects Pollinators; Higher Species Diversity in Organic

(Beyond Pesticides, December 21, 2022) Imagine plucking a flower and being able to find out every insect that recently visited that plant. Utilizing cutting-edge metabarcoding techniques, a team of Danish researchers has made that possibility a reality. By evaluating the environmental DNA (eDNA) left behind by insect pollinators alongside visual assessment surveys, a new study is providing an innovative way for farmers to improve pollination and protect on-farm biodiversity. Ultimately, study author Lene Sigsgaard, PhD, of the University of Copenhagen believes that, “With more knowledge of the pollinators in apples and other crops, we can begin to provide tailor-made flower mixes for individual crops, and improve our knowledge on the value of the surrounding landscape for wild pollinators.” Scientists focused on four different apple orchards throughout Denmark, three of which utilize pesticides (though only one sprayed during the study period), and another following organic practices. For each orchard, five apple flowers were collected from four separate rows. These flowers were then brought to the laboratory from DNA extraction. Scientists also conducted visual monitoring, whereby an observer stood between two orchard rows and recorded all flower visitors within roughly eight feet of themselves. The two methods of observation provide somewhat differing, […]

Mother and Child Health: Learning Disorders and Prenatal Pesticide Exposure Study Results Released

(Beyond Pesticide, December 20, 2022) A meta-analysis published in Chemosphere finds prenatal pesticide exposure, or pesticide exposure during pregnancy has a positive association with autism spectrum disorder (ASD) and attention deficit/hyperactive disorder (ADHD). Particularly, exposure to chemical classes organophosphate (OP) and pyrethroid (PYR) insecticides, in addition to the mother’s age during pregnancy (≥30 years old), increased the risk factor of ASD. ADHD risk increases among offspring whose mothers encounter organochlorine pesticides (OCPs) during gestation. The etiology or cause of ASD and ADHD involves the interaction of multiple components, including lifestyle and genetics. However, emerging evidence indicates that environmental contaminants like pesticides (e.g., occupational exposures, air pollution, solvents, dietary residues, etc.) play a role in disease etiology. Pesticide contamination is widespread in all ecosystems, and chemical compounds can accumulate in human tissues resulting in chronic health effects.  ADHD is estimated to affect 8-12% of school-age children worldwide. While it is a complex disease, and genetics may play a role, no specific genes have been identified, and there is increasing evidence that environmental factors like pesticide exposure facilitate the development of the condition. Additionally, U.S. Centers for Disease Control and Prevention (CDC) estimates that 1 in 54 children have been diagnosed with an autism spectrum […]

Denying Science, Manufacturing Doubt: Monsanto/Bayer’s Promotion and Defense of Glyphosate/Roundup

(Beyond Pesticides, December 16, 2022) A report released last week — Merchants of Poison: How Monsanto Sold the World on a Toxic Pesticide — exposes not only Bayer/Monsanto malfeasance in its “promotion” of its glyphosate-based herbicide products, including the notorious RoundupÂŽ, but also, the broader landscape of corporate efforts to white- or green-wash products that companies know are harmful to people and the environment. The report was issued by U.S. Right to Know (USRTK, a nonprofit investigative research group focused on promoting transparency for public health), Friends of the Earth (FOE), and Real Food Media. It carries the pithy subtitle, “A case study in disinformation, corrupted science, and manufactured doubt about glyphosate,” a description cited by the Friends of the Earth press release as “at the core of the pesticide industry’s public relations playbook.” Beyond Pesticides welcomes this report, which comports with much of our previous coverage of the pesticide industry’s egregious misbehavior, and of glyphosate, the world’s most widely used herbicide. FOE calls the report the “first comprehensive review” of the Bayer/Monsanto “defense strategy” employed in attempts to deny science, manufacture doubt, and discredit critics who have researched, reported on, and/or advocated against the company’s flagship glyphosate products because […]

Waterhemp: Herbicide Resistant Plant Created by Chemical-Intensive Farming Competes with Crops

(Beyond Pesticides, December 15, 2022) Industrial agriculture has both created and amplified the spread of the now highly problematic waterhemp (Amaranthus tuberculatus) plant, according to research published this month in the journal Science. Over the last 80 years, the push to increase monoculture plantings, expand cropland, and utilize chemical fertilizers and pesticides has changed waterhemp from a tame riparian wild plant into an aggressive, weedy intruder able to compete with row crops like corn and soybean. “The genetic variants that help the plant do well in modern agricultural settings have risen to high frequencies remarkably quickly since agricultural intensification in the 1960s,” said study author Julia Kreiner, PhD with the University of British Columbia’s Department of Botany. “The types of changes we’re imposing in agricultural environments are so strong that they have consequences in neighbouring habitats that we’d usually think were natural.” To better understand how this plant went from a waterside obscurity to North America’s most notorious “weed,” researchers tracked the shifts occurring within the plants genome. Using data from herbarium samples first collected in 1828 until 2011, scientists sought out alleles (genetic mutations) that corresponded with agricultural intensification and analyzed the frequency of their occurrence over the nearly […]

Estrogen-Mediated Cancers in Humans Have Links to Endocrine Disrupting Pesticides

(Beyond Pesticides, December 13, 2022) Pesticides have a long history associated with hormone (endocrine)-disrupting properties that induce various molecular changes, prompting disease development. Adding to the science, a review published in Environmental Exposure, Biomonitoring and Exposure Assessment highlights how specific estrogen-mimicking pesticides increase the risk of disease, particularly hormone-related cancers among women (i.e., breast, ovarian, endometrial cancer) and men (i.e., testicular, prostate cancer). Like pesticides, endocrine disruptors are xenobiotic (i.e., chemical substances foreign to an organism or ecosystem). Many reports demonstrate that exposure to endocrine-disrupting chemicals can adversely affect human, animal—and thus environmental—health by altering the natural bodily hormones responsible for conventional reproductive, physical, and mental development. Endocrine disruption can lead to several health problems, including hormone-related cancer development (i.e., thyroid, breast, ovarian, prostate, testicular), reproductive dysfunction, and diabetes/obesity that can span generations. Therefore, studies related to pesticides and endocrine disruption help scientists understand the underlying mechanisms that indirectly or directly cause cancer, among other health issues. Pesticides are one of the most potent xeno-estrogenic compounds, as estrogenic strength and environmental half-life exceed those of other xeno-estrogenic compounds. Focusing on organochlorine pesticides (OCs), the study evaluates the chemical effects on the physiological (anatomic) system to increase cancer risk. Using human studies, researchers assessed how estrogen-medicated cancer develops in women and men. […]

USDA Urged to Evaluate Undisclosed Inert Ingredients in Organic, as Required by Law

(Beyond Pesticides, December 12, 2022) It is time for the U.S. Department of Agriculture (USDA) to follow through on its duty to assess individual “inert” ingredients used in organic production. In creating the original regulations for the National Organic Program (NOP), USDA—based on the recommendation of the National Organic Standards Board (NOSB)—decided to postpone the evaluation of so-called “inert” ingredients until active materials had been reviewed for the National List of Allowed and Prohibited Substances. In this context, “inert” is a misleading legal term since the ingredient may be chemically or biologically active, but not included for purposes of attacking a target organism. The first regulation and all subsequent revisions have allowed the use of “inert” ingredients on EPA’s former Lists 4A (“minimal risk inert ingredients”) and 4B (“other ingredients for which EPA has sufficient information to reasonably conclude that the current use pattern in pesticide products will not adversely affect public health or the environment”). A limited number on List 3 (“inerts of unknown toxicity”) were allowed in pheromone products. [This action requires a submission at Regulations.gov. You can copy and paste from the suggested comment below. Comments are due December 31, 2022.] Tell USDA that the National Organic Program […]

UN Again Calls for Action as Biodiversity Deterioration Worsens Worldwide

(Beyond Pesticides, December 9, 2022) Representatives from more than 195 countries have descended on Montreal for the December 7 start of COP15 — the United Nation’s (UN’s) Conference of the Parties to the Convention on Biological Diversity (CBD). The UN Development Programme sets out the context for this summit: “Despite ongoing efforts, biodiversity is deteriorating worldwide, and this decline is projected to worsen with business-as-usual. The loss of biodiversity comes at a great cost for human well-being and the global economy.” Beyond Pesticides has documented many aspects of this decline in biodiversity, and the implications for ecosystem, human, and planetary health. In this COP15 context, the data points to the importance of broad adoption of organic regenerative / agroecological systems, which can very significantly address the interactive health, biodiversity, and climate crises. Close on the heels of November’s UN COP27 summit on climate, COP15 has commenced, with the goal of adopting a post-2020 Global Biodiversity Framework (CBF) to provide “a strategic vision and a global roadmap for the conservation, protection, restoration, and sustainable management of biodiversity and ecosystems for the next decade.” The first such summit was called the Convention on Biological Diversity and was held in 1993.

Childhood Pesticide Exposure Associated with Early Onset of Puberty

(Beyond Pesticides, December 8, 2022) Children with higher levels of certain pesticide metabolites are more likely to go through early puberty, according to research published recently in Environmental Pollution. The findings by a team of Spanish researchers speak to a need for greater protections for children from toxic pesticide exposure. Children are much more sensitive to pesticide exposure than adults as they take in greater amounts of toxics relative to their body weight and have developing organ systems. Managing homes and yards without chemicals and purchasing organic food whenever possible can significantly reduce childhood pesticide exposure.   Researchers began their investigation with children aged 7-11 participating in the Spanish state’s Environment and Childhood multicenter birth cohort stud, an ongoing project aimed at understanding the effect of environmental exposures on pregnancy, fetal, and childhood development in the country. Out of over 3,000 children enrolled in the project, 1,539 had their urine sampled for the presence of pesticide metabolites. Scientists focused on four insecticides breakdown products—a chlorpyrifos metabolite ‘TCPy’, a metabolite of the organochlorine diazinon ‘IMPy’, a general organophosphate metabolite ‘DETP’, the pyrethroid metabolite ‘3-PBA’, and a metabolite of ethylene-bis-dithiocarbamate fungicides ‘ETU’. Urinary levels of these pesticide metabolites were then compared against […]

Developed Countries with 18% of World Population Responsible for 49% of Pesticide Hazard Footprint

(Beyond Pesticides, December 7, 2022) A recent study from Australian researchers has investigated pesticide use through an unusual lens — by quantifying the environmental footprints of pesticide use in 82 countries and territories (and eight regions), and then concluding that international trade drives significant pesticide use. The researchers identify the U.S., Brazil, and Spain as the biggest exporters of the “pesticide hazard load” associated with those environmental footprints, and China, the United Kingdom, and Germany as the top three importers. They lay responsibility for this hazard load at the feet of the unsustainable intensification of chemical-intensive agriculture (via synthetic pesticide and fertilizer use during the past 50 years), and ratcheting consumer demand for goods and services. Indeed, they conclude that the latter, in “developed” countries, is responsible for a substantial portion of the pesticide pollution in other countries. The study authors note that previous “efforts to quantify the environmental footprints of global production and consumption have covered a wide range of indicators, including greenhouse gas emissions, water scarcity, biodiversity, nitrogen pollution, acidification, land use, and others, but they have largely missed . . . represent[ing] the environmental pressures exerted by pesticide use.” The researchers set themselves the task of quantifying […]

Ocean Health: Environmental Pollutants Threaten Humpback Whale Reproduction and Offspring

(Beyond Pesticides, December 6, 2022) Persistent organic pollutants (POPs)—including banned pesticides—present a health risk to humpback whales (Megaptera novaeangliae), according to a study published in Environmental Pollution. Regarding female humpback whales, levels of POPs in blubber are higher in juveniles and subadults than in adults, primarily from the transference of contaminants from the mother to her calf.  Organochlorine compounds (OCs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are well-known persistent organic pollutants. The international Stockholm Convention treaty (signed by 152 countries, but not the U.S.) banned these primary pollutants of concern (UNEP, 2009) in 2001 (taking effect in 2004) because of their persistence, toxicity, and adverse effects on environmental and biological health. These pollutants have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. However, these chemicals can remain in the environment for decades and interact with various current-use pesticides, including organophosphates, neonicotinoids, and pyrethroids. Although various studies demonstrate the volatile, toxic nature of POPs, much less research evaluates the impact POPs have on maternal offloading or transfer of contaminates to offspring and respective health consequences. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one […]

Federal Court Sets Deadline for EPA to Implement Endangered Species Protections from Toxic Insecticide

(Beyond Pesticides, December 1, 2022) The U.S. Environmental Protection Agency (EPA) must put measures in place to protect endangered species from the hazardous insecticide cyantraniliprole before September 2023. The requirements stems from a recent federal appeals court ruling that found EPA in violation of its statutory obligations under the Endangered Species Act (ESA). The agency originally lost its legal case on this chemical in 2017, but has since done nothing to fulfill the initial court order, necessitating further litigation by conservation groups. “It’s outrageous that the EPA is thumbing its nose at a federal court order even as cyantraniliprole wreaks havoc on our most endangered wildlife,” said Jonathan Evans, environmental health legal director at the Center for Biological Diversity. “The EPA has acknowledged that this pesticide is incredibly toxic to bees and other invertebrates, but the agency is so accustomed to putting the profits of the pesticide industry ahead of its duty to protect human health and our environment that for years it simply ignored a direct court order.” Cyantraniliprole is a systemic insecticide registered for use in 2014. It presents similar risks to pollinators and wildlife as other widely used systemics, such as the neonicotinoid class of chemicals. Its […]

Continued Reduction in Sperm Count Raises Call for Action

(Beyond Pesticides, November 29, 2022) Based on new international research adding weight to previous research on falling sperm counts, it is critical that environmental agencies address this and other problems related to endocrine disruption. The study by Levine et al. finds that the drop in sperm count—a drop of 51.6% from 1973 through 2018—is global and that the rate of decline is accelerating. Tell EPA and Congress that pesticide use cannot continue without findings of no endocrine disruption.  The documented (average) drop in sperm counts is approaching the level at which the ability to cause a pregnancy begins to plummet dramatically. The reduction in male fertility may have profound psychological and social impacts, including anxiety, low self-esteem, and depression. These psychological problems have health impacts of their own. Equally serious are connections of anxiety and depression with violent behavior and suicide. Compounding the problem is the fact that men are unlikely to seek fertility-related social support. The drop in sperm counts is just one example of endocrine disruption largely due to exposure to toxic chemicals. The endocrine system consists of a set of glands (thyroid, gonads, adrenal and pituitary) and the hormones they produce (thyroxine, estrogen, testosterone, and adrenaline), which […]

Hormone Mimicking Properties of Glyphosate Weed Killer and Related Compounds Increase Breast Cancer Risk

(Beyond Pesticides, November 25, 2022) A study published in Chemosphere adds to the growing body of research demonstrating the endocrine (hormone) disrupting effects of glyphosate play in breast cancer development. Exposure to the herbicide glyphosate and other glyphosate-based herbicides (GBHs) at high concentrations mimics the estrogen-like cellular effects of 17β-estradiol (E2), altering binding activity to estrogen receptor Îą (ERÎą) sites, thus causing fundamental changes in breast cancer cell proliferation (abundance).  Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, not just Bayer’s (formerly Monsanto) RoundupÂŽ. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in food and water commodities. In addition to this study, literature proves time and time again that glyphosate has an association with cancer development, as well as human, biotic, and ecosystem harm. Therefore, advocates point to the need for national policies to reassess hazards associated with disease development and diagnosis upon exposure to chemical pollutants. The researchers note, “The results obtained in this study are of toxicological relevance since they indicate that glyphosate could be a potential endocrine disruptor in the mammalian system. Additionally, […]

Study Finds that Pollinators, Not Pesticides, Are More Important to Higher Crop Yields

(Beyond Pesticides, November 23, 2022) A new study throws into question the value of the pest management concept of setting action levels around pest infestations. In the course of watermelon production over a span of two years, pollination, not pest levels, was the key determining factor for yield. “These data advocate for a reprioritization of management, to conserve and protect wild bee pollination, which could be more critical than avoiding pest damage for ensuring high yields,” the study, published in Proceedings of the Royal Society B, indicates. Action levels are considered an important aspect of an integrated pest management (IPM) approach in agriculture, whereby a pest infestation reaches levels considered economically unacceptable, leading to a decision to engage in pest control. The concept of IPM however has been influenced by the chemical industry over the decades since its original definition and recent data indicates that it has failed to stop toxic pesticide use. The original intent of IPM was the adoption of preventive practices and utilization of nonchemical tools, placing pesticide use as a last resort when pest control is warranted. However, farms that self-identify as IPM operations use pesticides, sometimes as the first line of defense, while attempting to […]

Fungi that Survive Fungicide Use Multiply and Thrive

(Beyond Pesticides, November 22, 2022) Fungus that survive a fungicide application may be able to multiply and thrive, putting plant yields at risk. This finding comes from research recently published by scientists at University of Illinois, focusing on the impact of fungicide use on soybean yields and the disease Septoria brown spot, caused by the fungus Septoria glycines. The research underlines the danger of preventive chemical applications in an attempt to protect yield and shows how precarious pesticide use can be when subject to the complexity seen in field conditions. Scientists began with the intent of analyzing the soybean’s phyllosphere mycobiome, the fungal microbial make-up of the outside of the plant, including all its surfaces above-ground. A field trial was established near Urbana, Illinois, and soybeans plants were separated into four different plots according to their treatment. One group was inoculated with Septoria glycines, another inoculated and sprayed with a fungicide, a third not inoculated yet sprayed with a fungicide, and a final control group neither inoculated nor treated with a fungicide. A range of different analyses were conducted to view changes in the disease development and mycobiome composition over time. Soybean plants that had been inoculated with Septoria showed […]

EPA’s Deficient Pesticide Analysis Contributes to Ecological Decline

(Beyond Pesticides, November 21, 2022) Once again, the Environmental Protection Agency (EPA) has registered a new pesticide without performing a thorough review of its impacts on biodiversity as well as threatened and endangered species. Inpyrfluxam was registered in 2020 and only after being sued by the Center for Biological Diversity for failure to comply with the Endangered Species Act (ESA) did EPA commit to completing draft effects determinations by Fall 2022. Once again, EPA’s draft biological evaluation is incomplete and inadequate. EPA is accepting comments on its draft biological evaluation at Regulations.gov.  Tell EPA and Congress that Pesticide Registrations Require Complete Science. The Review of Inpyrfluxam is Incomplete and Inadequate.  The agency’s draft effects assessment is flawed and incomplete. We share the details because it shows that EPA is out of step with the science and its regulatory responsibility when it comes a thorough review for ecosystem effects of pesticides.   The agency used fish early life stage (ELS) tests to estimate chronic fish toxicity. This is inappropriate. The fish ELS is a sub-chronic test of sensitive life stages. Although it is often used as a surrogate or predictor of chronic toxicity, it does not adequately address potential adverse effects on reproduction or transfer of the test chemical to eggs/offspring […]

Co-Exposure to Organophosphate Insecticides and Covid-19 Elevates Threat of Cardiovascular Disease

(Beyond Pesticides, November 17, 2022) A report published in Toxicology and Applied Pharmacology finds organophosphate (OP) insecticides and the coronavirus (SARS-CoV-2/Covid-19) illicit similar damage to the heart and co-occurring exposure to both can escalate cardiac (heart) injury. Previous research suggests OPs may increase the ability of SARS-CoV-2 to cause COVID-19, especially among vulnerable individuals with underlying medical conditions. OPs have a wide range of biological uses—from insecticides to flame retardants—that make these chemicals ubiquitous, significantly contributing to ecosystem contamination. These compounds have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. OPs are highly toxic, originating from the same compounds as World War II nerve agents, and residues are consistently present in human and animal blood, urine, tissues, and milk. Moreover, OPs are one of the leading causes of poisoning globally. Therefore, it is vital to understand how OP exposure will impact human health in conjunction with other immunologically compromising diseases like COVID-19. Cardiovascular diseases are among the leading causes of death globally. Additionally, heart conditions are one leading cause of disability in the U.S., as research demonstrates environmental pollutant exposure can increase the risk of developing cardiovascular disease, including stroke, heart attack, heart failure, atrial fibrillation, and cardiac […]

Synthetic Fertilizers and Pesticides Make Plants Less Attractive to Bumblebees, Research Shows

(Beyond Pesticides, November 15, 2022) Spraying a flowering plant with synthetic fertilizers makes it less attractive to bumblebees, according to research published this month in PNAS Nexus.  “A big issue is thus—agrochemical application can distort floral cues and modify behaviour in pollinators like bees,” said study author Ellard Hunting, PhD, of the University of Bristol, UK. The findings underscore the limited understanding that proponents of chemical agriculture have for the complex processes that food production relies upon and reinforce calls for a broad scale transition to regenerative, organic farming practices. Scientists began with the knowledge that spray applications of various agrichemicals affect the visitation patterns of bumblebees and other pollinators through a range of different processes. Past research finds that notorious bee-killing neonicotinoid insecticides not only kill bees outright, but also result in a range of complex damage, including their ability to impede bees’ olfactory senses and adversely affect their vision and flying ability. Other chemicals like glyphosate weaken bees’ ability to distinguish between colors.   A growing area of research is investigating the ways in which pollinators use static electric fields surrounding flowers to find food sources. A 2013 study found that bumblebees use floral electrical fields to discriminate […]

Findings Add to Crisis, Antibiotics in Agriculture, Lawns, and Landscapes Threaten Health

(Beyond Pesticides, November 14, 2022) Glyphosate weed killers induce antibiotic resistance in deadly hospital-acquired bacteria, according to a new study published late last month in the journal Scientific Reports. This is the latest finding connecting commonly used herbicides to the rise of antibiotic resistant bacteria. To put this finding in context, antibiotic resistance is rising to dangerously high levels in all parts of the world, according to the World Health Organization. In the May 1, 2022, issue of the Bulletin of the World Health Organization, Samira Choudhury, PhD, et al. writes, “Often referred to as the silent pandemic, antimicrobial resistance claims the lives of over 700,000 people annually.” The authors continue, “A study suggests that if no actions are taken, antimicrobial resistance will cause 10 million deaths per year by 2050 and an economic impact of over 100 trillion United States dollars.” Tell EPA and Congress that antibiotic pesticides in agriculture, lawns, and landscapes must be eliminated. Use of antibiotics in animal agriculture has long been recognized as a contributor to widespread antibiotic resistance. More recently, recognition of the contribution of antibiotics in plant agriculture has led to pressure to eliminate agricultural uses of antibiotics used in medicine. However, two facts […]

Weed Killer Use Destroys Soil Life and Ecosystems, Paper Finds

(Beyond Pesticides, November 11, 2022) A paper published in Trends in Ecology & Evolution in late October sounds an unnerving alarm about the globally ubiquitous use of herbicides and the ecological destruction being caused. It asserts that widespread environmental contamination with these herbicide compounds is influencing soil, plant, and animal microbiomes in ways that are not only not well understood, but also, can have significant impacts on the functioning of organisms and their ecosystems — with evolutionary implications. Impacts of herbicides on microbiota in soils include, for example, those on nutrient cycling, and altered organism and plant performance, which can affect pollination and animal consumption of plants. This research reinforces what Beyond Pesticides wrote in covering a 2021 study: “The popular herbicide glyphosate negatively affects microbial communities, indirectly influencing plant, animal, and human health. Exposure to sublethal concentrations of glyphosate shifts microbial community composition, destroying beneficial microorganisms while preserving pathogenic organisms.” Herbicides are a category of pesticide used to control weeds in agriculture and commercial forests, on managed landscapes, byways, gardens, and lawns, and directly on surface waters to control aquatic weeds. They are designed to kill “target” plant species considered undesirable in any of those circumstances. Herbicide use has exploded […]

Kids and Kidney Cancer: Implication for Prenatal Pesticide Exposure

(Beyond Pesticides, November 10, 2022) A meta-analysis by the University Alberta Hospital, Edmonton, AB, Canada, adds to the plethora of research linking prenatal (before birth/during pregnancy) pesticide exposure to carcinogenic (cancer) tumor development. The analysis, published in Human & Experimental Toxicology, finds parental exposure to pesticides during the preconception (before pregnancy) or pregnancy period increases the risk of Wilms’ tumor (a type of kidney cancer) occurrence among children. Already, studies find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects, from metabolic disorders to mental and physical disabilities. Although medical advancements in disease survival are more prominent nowadays, childhood cancer remains the leading cause of death from disease among children. Furthermore, childhood cancer survivors can suffer from chronic or long-term health complications that may be life-threatening. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Moreover, a mother’s pesticide exposure can have a stronger association with cancer among a child than childhood exposure, and a newborn can still encounter pesticides. Therefore, it is essential to understand how pesticides impact the health and well-being of individuals during critical developmental periods, especially for latent diseases (e.g., cancers). The researchers performed a systematic review and meta-analysis on case-control studies […]

“RobotFalcon” Takes to the Skies to Replace Pesticides and Lethal Tactics to Deter Birds at Airports

(Beyond Pesticides, November 9, 2022) A team of Dutch researchers has developed an artificial predator dubbed the RobotFalcon that can quickly and successfully scare bird flocks away from fields, providing a new practical, ethical tool to deter bird strikes near airports. Although it sounds like a conspiracy theory, in the skies above Workum, The Netherlands, for a period of time, some of the birds were not real. Current data indicate there are over 17,000 wildlife strikes to aircraft each year in the U.S., costing an estimated $500 million in economic losses, yet these problems are ongoing despite the U.S. Department of Agriculture’s Wildlife Services program killing hundreds of thousands of birds in and around airports each year through a range of lethal means, including the use of guns and pesticides. As a result, new management approaches that focus on effective, nonlethal alternatives to the use of toxic chemicals are urgently needed. Scientists began their research with the understanding that most bird deterrent methods “suffer from some degree of habituation: after repeated exposure, birds respond less.”  While habitation can be reduced through natural threats, the authors note that approaches like falconry are lethal and can be prohibitively expensive and difficult to […]
