(Beyond Pesticides, November 19, 2024) Researchers at Stanford University recently published a study in Cancer, an international interdisciplinary journal of the American Cancer Society (ACS), that reveals a correlation for numerous pesticides with increased prostate cancer occurrence and associated death. The study finds that exposure to 22 pesticides is positively associated with prostate cancer. The 22 pesticides include 2,4‐D, acephate, azoxystrobin, bifenthrin, carbaryl, chloropicrin, cloransulam‐methyl, cyhalothrin‐lambda, diflufenzopyr, diuron, glyphosate, hexazinone, linuron, methyl parathion, pendimethalin, propiconazole, sulfosate, thiamethoxam, thifensulfuron, tribenuron methyl, trifloxystrobin, and trifluralin. (See more on 2,4-D and cancer prevalence here and here.) As prostate cancer is a leading national health concern, the authors investigate agricultural pesticide exposure and compared it to prostate cancer incidence and mortality across counties in the contiguous U.S. “The geographic variation in prostate cancer incidence and mortality suggests that regional environmental factors, such as pesticide exposure, may contribute to the development of prostate cancer,” the researchers postulate. In comparing county‐level associations of 295 pesticides and prostate cancer reports, the authors were able to conduct an environment‐wide association study (EWAS) to determine any statistically significant links. “We acquired annual estimated total usage data (kg per county) for all pesticides reported and applied to agricultural crops grown […]

(Beyond Pesticides, November 13, 2024) A study in Chemosphere, conducted by researchers from the Institute of Biochemistry and Molecular Biology in Germany, reveals the varied lethal and sublethal effects of different glyphosate mixtures through tests on the South African clawed frog, Xenopus laevis (X. laevis). After exposing embryos to four glyphosate formulations, mortality, morphological defects, altered heartbeat rate, and impaired heart-specific gene expression are observed. Glyphosate, an herbicide and popular weed killer in many Roundup® products, is one of the most commonly detected pesticides in waterbodies worldwide, threatening aquatic organisms and overall biodiversity. This study investigates the effects of Glyphosat TF, Durano TF, Helosate 450 TF, and Kyleo, four formulations containing glyphosate, as compared to the effects of pure glyphosate on embryonic development in amphibians. The formulations consist of varying concentrations of the active ingredient glyphosate, as well as other active and inert ingredients. The authors share that, “Glyphosat TF contains 34% glyphosate and 10–20% d-glucopyranose, while Durano contains 39–44% glyphosate and 1–5% N–N-dimethyl-C12-C14-(even numbered)-alkyl-1-amines. In Helosate most of the ingredients are listed – 50–70% glyphosate, 1–10% isopropylamine, 1–3% lauryl dimethyl betaine, 0.25–1% dodecyl dimethylamine. Kyleo only lists the active ingredients glyphosate (27.9%) and 2,4-D (32%).” 2-cell stage embryos (early […]

(Beyond Pesticides, November 1, 2024) In a study published earlier this year in Soil Science Society of America Journal, researchers at Kansas State University document direct evidence that organic amendments (e.g., manure and compost) in a no-till agricultural system “facilitat[e] microbial diversity” that cycles plant-available nutrients. The study was published just as farmers are looking for less expensive practices that support the economic vitality of their farms amid surging prices for petrochemical pesticides and fertilizers and as agricultural support programs are threatened by unresolved issues in Farm Bill talks on Capitol Hill. [See the recent Action of the Week calling on Congress to take action.] Simultaneously, awareness is growing among environmental and public health advocates about the importance of soil health to ecosystem stability in combatting climate change-induced natural disasters and stopping plummeting biodiversity. Demands for new systems rooted in organic principles and land management practices continue to become more widely recognized by farmers, environmentalists, and the broad public. The study adds to earlier findings and contributes to the body of scientific literature on soil health and its importance to ecosystem and human health. Methodology and Results The study was led by researchers at Kansas State University specializing in agronomy […]

(Beyond Pesticides, October 15, 2024) In Environmental Epidemiology, researchers from Columbia University and the University of Southern California, along with representatives from the nonprofit Comite Civico del Valle in Brawley, California, report the heightened risk of wheezing for five- to twelve-year-olds in the rural communities of California’s Imperial Valley. Through a school-based survey, the authors find associations between living near pesticide applications and more wheeze symptoms among the children. According to the authors, residents of the Imperial Valley, which is located near the border between the United States (U.S.) and Mexico, “are primarily Latino, 1 in 3 children live in poverty, and there is a 20% unemployment rate. The county faces poor air quality and excess particulate matter levels. Further, one in five children is diagnosed with asthma and the rate of asthma-related pediatric emergency room visits and hospitalizations is two times the CA state average.” This highlights the disproportionate risk for residents in this area regarding environmental exposure to harmful chemicals. Children are already more susceptible to health complications following pesticide exposure, as they take in greater amounts of toxic chemicals relative to their body weight and have still-developing organ systems. Young children in environments with higher levels of […]

(Beyond Pesticides, September 19, 2024) An article published in the journal Science of the Total Environment finds that the European Union’s (EU) risk assessment process, required for registration, fails to accurately or reliably predict pesticide exposure rates, sometimes by several orders of magnitude. Pesticide registration in the EU leverages the Agricultural Operator Exposure Model (AOEM)—a predictive model developed in 2014 to estimate expected non-dietary pesticide exposure levels for operators [pest control operators in the U.S.] based on a very limited set of data generated by the pesticide industry. Models that predict real-world exposure and underestimate field data raise critical questions about the efficacy of risk assessment reviews that determine product labels and allowed level of harm. By comparing the dermal exposure measured during a field study conducted in a nonagricultural area with the corresponding values estimated by AOEM, researchers in France add to the body of scientific literature indicating that the fossil fuel and petrochemical pesticide industry data cannot be relied upon as a benchmark to ensure public health and safety. The study describes the difficulty and complexity of calculating the ability of protective equipment to provide protection. According to the authors, “[AOEM] underestimated hand exposure by 42 times and […]

(Beyond Pesticides, September 17, 2024) Today, International Microorganism Day, is a prime moment to focus on the complexity of billions of living beings that establish the foundation of land management and food production. Organic advocates, community members, and farmers identify the protection and enhancement of biological diversity in the soil as a key goal, especially in light of mounting concerns over rising microbial resistance to chemical-intensive practices. A recent article in British Journal of Environmental Sciences points to several microbial populations adversely affected by pesticide-contaminated soil on various farmland plots in Nigeria. There are significant variations in bacteria presence between pesticide-treated and control plots, with a lab analysis finding “[s]eventy-five percent (75%) of pesticide residue was detected in the soil samples,” which includes paraquat dichloride, endosulfan, diazinon, and N-(phosponomethyl)glycine [glyphosate]. This report builds on years of research from higher education institutions worldwide, including participatory research centering applied experiments on farmland, demonstrating the consequences of relying on pesticide-intensive agriculture and land management. The main goal of this report is to “determine the influence of pesticide contamination on the microbial population, physiochemical parameters and pesticide residue of soil of selected farmlands in Otuoke, Bayelsa State, Nigeria.” Researchers document the presence of eleven […]

(Beyond Pesticides, September 3, 2024) A piercing investigative article in the August 14 New York Times by journalist Greg Donahue reveals the abandonment of a group of brain disease patients in an area of Canada with forestry management for paper products, agriculture, and large amounts of pesticide use, including glyphosate. It illustrates the tension in the relationship between government authorities, regulated industries, and neurologist (physician) on the front lines. The article details the manner in which health officials appeared to manipulate their own investigation of a disease cluster to make it less disruptive to the economy of the Canadian province of New Brunswick. (This Beyond Pesticides analysis, where not otherwise indicated, draws on Mr. Donahue’s article.) New Brunswick has one major town, Moncton, and a large rural area characterized by agriculture and forestry. The province’s agriculture industry is dominated by blueberry production, which occupies the fourth largest amount of agricultural land in New Brunswick. About half the province is forested, with increasing amounts of land devoted to tree plantations intended for paper production. Glyphosate is hands-down the most heavily used pesticide in New Brunswick forestry, and New Brunswick is second only to Ontario in Canada’s total area of glyphosate-treated forest. […]

(Beyond Pesticides, August 21, 2024) A literature review, published this month in the Journal of Agricultural and Food Chemistry, explores levels of pesticide residues found in samples of human urine with environmental exposure and dietary intake and confirms prior findings about the benefits of an organic diet. Similar to past findings, lower concentrations of chemicals are detected in the urine of participants who report eating an organic diet. By analyzing 72 scientific research studies published between 2001 to 2023, the review assesses routes of exposure and “explores urinary concentrations and detection frequency of metabolites of organophosphates and pyrethroids, as well as herbicides such as 2,4-D and glyphosate,” the authors say. While “exposure to pesticide residues is influenced by a variety of demographic factors, including occupation, agricultural practices, seasonal variations, residence, diet, age, and gender,” the authors say, the concentrations of pesticides and their metabolites in human urine highlights the disproportionate risk to certain groups as well as the overall threat to the health of humans and the environment. Pesticide exposure can occur from dermal/skin contact or inhalation, through residence or work, and with dietary intake. “Pesticides in urine can be detected as parent compounds, specific metabolites corresponding to a specific […]

(Beyond Pesticides, August 13, 2024) With novel methods to provide a big-picture view of the overlap between high pesticide use and cancer incidence across the U.S, a new study has again linked pesticide exposure to a range of cancers. The study by Jacob Gerkin, D.O. and colleagues, “Comprehensive assessment of pesticide use patterns and increased cancer risk,” published in Frontiers in Cancer Control and Society, examines the association between high-pesticide use and cancer diagnoses along with smoking incidence data and the Social Vulnerability Index, a measure used by the Centers for Disease Control and Prevention (CDC) that includes variables such as poverty, poor housing, and exposures to natural disasters and chemical spills. The researchers consider 69 pesticides used in agriculture that are monitored by the U.S. Department of Agriculture. They use U.S. Geological Survey data to map areas of similar crops and pesticide use patterns and incorporate public health data from the CDC to develop their final picture. In terms of threats to health, cancer remains top of mind for most people. Globally, about ten million people die of cancer each year. And while treatments for cancer and survival times have burgeoned over the years, many cancers—particularly colorectal and breast […]

(Beyond Pesticides, July 25, 2024) On July 10, the Oregon Court of Appeals ruled that the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) does not preempt pesticide exposure victims’ state law claims against pesticide manufacturers, based on reporting from The New Lede. This decision builds on years of judicial precedent from the Supreme Court of the United States (SCOTUS) that protects individuals’ right to use failure-to-warn claims against producers of toxic pesticides, including Bayer-Monsanto. The importance of judicial review is critical to protecting the public against public health impacts of toxic pesticide use in the context of last month’s SCOTUS decision ending Chevron Doctrine, and with it the end of deferring to federal regulatory agencies on ambiguities in statutory mandates. A growing coalition of environmental and public health advocates, organic farmers, trial attorneys, farmworkers, and physicians are united in pushing back against a concerted effort by industry and its allies to attack victims’ ability to sue under “failure-to-warn” through the Farm Bill, state legislatures, and the proposed federal budget for Fiscal Year 2025. Oregon Court of Appeals In 2022, a local trial court in Oregon ruled in favor of Monsanto on a lawsuit initiated by Jackson County residents Larry and […]

She will be inaugurated on October 1, 2024. Dr. Sheinbaum’s ascension to the presidency comes at a time of increasing pressure from the United States government to acquiesce to its demands to open agricultural markets to genetically engineered (GE) crops (particularly corn) and the use of the carcinogenic weed killer glyphosate. With the formal review of the United States-Mexico-Canada Agreement (USMCA) approaching in 2026, Mexico will soon decide under Dr. Sheinbaum’s leadership whether it will be an international stalwart against the unfettered spread of GE corn amidst pressure from the U.S. Trade Representative and as industry continues to enable the cascading crises of the climate emergency, public health crisis, and biodiversity collapse. With new administrations in the United Kingdom and France, and the upcoming election in the U.S., how governments around the world, independently and collectively, choose to seriously confront or soft-pedal the existential environmental crises will determine the livability of […]

(Beyond Pesticides, July 2, 2024) Men’s Mental Health Awareness Month, which took place last month, evokes concern about the growing body of science linking pesticide exposure to neurological effects linked to depression. Recent studies reveal elevated rates of psychiatric disorders, including suicide, among farmers, with problems more common for males.  Through systematic reviews, meta-analyses, surveys and interviews, and blood sampling, these three studies add to the growing body of science linking pesticide exposure to neurological impacts. First, in the Journal of Agromedicine, researchers from Greece and the United Kingdom review eight studies and find a significant positive association between pesticide poisoning and depression in agricultural populations.1 Second, a study in Toxicology shows a link between depression in Brazilian farmers and pesticide exposure, most notably with glyphosate usage.2 Third, the latest study in Environmental Toxicology and Pharmacology focuses on work by researchers from Spain in identifying farmers exposed to chlorpyrifos, mancozeb, and malathion that have higher rates of depressive symptoms and suicide attempts.3  Through a meta-analysis of published research, the authors of the Agromedicine journal article identify pesticide poisoning as a risk factor of depression. With depression affecting more than 264 million individuals worldwide, this is a field of interest with […]

(Beyond Pesticides, June 12, 2024) A study of pesticide contaminated algae finds that the disruption of algal communities has a devastating effect on the health of the aquatic food web. The study findings show that contact with pesticides can result in changes to “algal physiology, causing tissue injury, developmental delay, genotoxicity, procreative disruption, and tissue biomagnification” that alters the dominance of algae species in the environment. This in turn “can impact higher trophic levels and have a domino effect on the aquatic food web. It is possible for biodiversity to disappear, reducing ecosystem stability and resistance to environmental alterations,” the authors state. The study, a worldwide literature review conducted by researchers from India, South Korea, and Saudi Arabia, appears in Aquatic Toxicology.  The health of aquatic ecosystems is at risk with indirect effects on nontarget species from pesticides in the environment. This includes impacts on species of fish, invertebrates, microbial communities, and marine mammals. In explaining the importance of extensively studying effects of pesticides, the researchers note, “Different pesticide classes have different chemical structures, which define their modes of action and affect how they interact with both target and nontarget organisms.” Because of this, the range of effects seen from […]

(Beyond Pesticides, June 11, 2024) Published in Science of The Total Environment in May, a comprehensive literature review of population-based studies finds strong linkages between direct and acute pesticide exposure and elevated risk of breast cancer (BC). A majority of the studies analyzed in this review were based on population groups in the United States, but also extends to Australia and three European countries (Greece, France, and Italy). Included in these studies are women who worked in chemical-intensive agricultural settings, directly sprayed pesticides in their at-home gardens, and/or handled pesticide-contaminated clothing. The findings in this literature review underscore organic advocates’ concerns of relying on pesticide substitution models that inevitably impact the health of land stewards, farmers, farmworkers, and the broader public rather than transforming food systems to an organic model that bans the use of toxic petrochemical-based pesticides. The goal of this review was to synthesize existing literature on pesticide exposure and breast cancer to determine the specific pathways and underlying mechanisms that contribute to female participants’ heightened risk. This literature review was published online by researchers at the University of Arizona’s R. Ken Coit College of Pharmacy and Coit Center for Longevity and Neurotherapeutics and the Laboratory of Tumor […]

(Beyond Pesticides, June 4, 2024) A study published in the most recent edition of the journal Ecotoxicology and Environmental Safety documents for the first time the presence of the herbicide glyphosate in human sperm. The study looked at 128 French men with an average age of 36 years who tested positive for glyphosate in their blood. Seventy-three out of the 128 men were found to also have glyphosate in their seminal plasma. Not only that, the amount of glyphosate in seminal plasma was nearly four times higher than what was detected in the blood.   Methods  The study involved a population of 128 infertile French men from whom seminal and blood plasma samples were collected. The study was conducted at the “Pole Santé Léonard de Vinci” medical center, located centrally near Tours, France. This region is recognized for its urban characteristics as well as being a major agricultural hub, particularly for grain and wine production. The study authors note, “This area reflects the common herbicide exposure in France” and the district ranks third highest in terms of pesticide purchases. While additional qualitative data was collected, only 47 of 128 participants fully completed a questionnaire about their profession, diet (organic or […]

(Beyond Pesticides, May 15, 2024) A study published recently in the journal Environmental Research finds a significant correlation between exposure to certain pesticides and an elevated risk of inflammatory bowel disease (IBD), a chronic autoimmune condition of the gastrointestinal tract. The study, adding to the body of science on this subject, evaluates self-reported data from licensed pesticide applicators and their spouses exposed to pesticides for over 20 years. In addition, while some of the chemicals found to be most closely associated with incidents of IBD have been banned from use, they are “forever” chemicals that persist in the environment for generations. These findings demonstrate once again the failings of the current regulatory process to identify hazards before they are put into the environment. The study found evidence that exposure to several organochlorine insecticides (dieldrin, DDT, and toxaphene), as well as organophosphate insecticides (parathion, terbufos, and phorate) and herbicides (2,4,5-T, 2,4,5-TP, and metolachlor), is associated with elevated IBD risk. IBD is a generic term for diseases that result in chronic inflammation of the gastrointestinal tract, such as Crohn’s disease and ulcerative colitis. It is estimated that 6.8 million patients globally suffered from IBD in 2017. IBD may result from an imbalance […]

(Beyond Pesticides, April 25, 2024) In a study from earlier this year, “Pesticides: An alarming detrimental to health and environment,” scientists compiled research from 154 articles regarding pesticide use and the adverse effects they have on the environment and human health. Among the effects of the harmful pesticides described is genotoxicity—the alteration of genetic material that results in the mutations in DNA that cause cancer.  The authors state that “genotoxins are mutagenic chemicals, and exposure to them increases the risk of developing tumors, hormonal changes, DNA damage, and changes in the ovaries and eggs, all of which leading to cancers… The risk of DNA damage surges with increased genotoxicity in people exposed to pesticides.” In addition, the National Institute of Health states that all “pesticides are highly biologically active chemicals. They may interact with DNA and damage its structure.” Despite these documented risks, pesticide use continues to surge.  While phased out to a considerable extent after being widely used in agriculture and residential areas, organochlorine pesticides (OCPs) like dichlorodiphenyltrichloroethane (DDT) or its breakdown compound dichlorodiphenyldichloroethylene (DDE) continue to show up as residues in the environment and food supply. Symptoms in humans that have been exposed to these chemicals include: seizures, […]

(Beyond Pesticides, April 18, 2024) University of Michigan researchers have found a statistically significant relationship between heightened risk of amyotrophic lateral sclerosis (ALS) and household exposure to lawn care products and pesticides. The study results were published earlier this month in Amyotrophic Lateral Sclerosis and Frontotemporal Degeneration. The interdisciplinary research team concludes that modifying residential exposure to toxic substances, including pesticides, can play an important role in ALS susceptibility and prognosis. The results build on a substantial body of scientific literature identifying pesticide exposure in various ALS cohort studies. Advocates say that these adverse effects, along with other numerous health and environmental effects, inform their call for the phaseout of toxic pesticide use and the adoption of alternative practices and eco-compatible products. All participants in this study are patients at the University of Michigan Pranger ALS Clinic with Gold Coast ALS diagnosis, which according to a Muscle & Nerve study refers to the identification of two factors: “progressive motor impairment documented by history or repeated clinical assessment” and “the presence of upper and lower motor neuron dysfunction in a least one body region.” All 367 ALS and 255 control patients were tasked with completing a survey in which they self-reported […]

(Beyond Pesticides, April 2, 2024) There is a nascent capital investment effort in the transition to certified organic agriculture beginning to take hold across the U.S., something advocates say is critically needed to meet the current and escalating existential health threats, biodiversity decline, and climate emergency. Mad Agriculture has received early commitments from the Rockefeller Foundation, Builders Vision, and nearly a dozen other investors to contribute to the $50 million Perennial Fund II (PFII), to advance the growth of “regenerative organic” agriculture. Forbes is reporting that PFII’s primary objective is to jumpstart the organic land transition, given that this slice of U.S. agriculture makes up less than one percent of total farmland in the country relative to the European Union’s nearly 10 percent of total farmland. “We commend the work of Mad Agriculture in harnessing the spirit of organic agriculture and mobilizing the private sector to invest in farmers who engage in regenerative organic agricultural practices,” said Max Sano, organic program associate at Beyond Pesticides. In Rockefeller Foundation’s press release announcing their early commitment, Mad Capital co-founder Brandon Welch spoke on their vision: “We are aiming to build a bridge between two distant worlds that need one another to transition […]

(Beyond Pesticides, March 26, 2024) The authors of a case study in Canale D’Aiedda, Taranto, Italy, published in Scientific Reports, conclude that, “[T]he results of monitoring and modeling activities revealed a chronic risk associated with the presence of Cu [copper] from November to April in several river reaches and acute risk associated to the presence of glyphosate in several reaches mainly in the wet season.”  According to the authors, “The most important factor influencing the chronic risk for Cu were the combination of two factors: the high surface runoff and the Cu applications. The most important factor influencing the glyphosate peaks of concentration is the streamflow.” The authors of the study measure the flow of pesticide concentrations through the soil and water assessment tool (SWAT). The ecotoxicological data was collected at two stations in Germany that flow into Italy, within the Canale d’Aiedda basin. The streamflow was monitored between August 2017 and December 2019. Out of hundreds of pesticides and six metabolities investigated in this study, “only traces of copper and glyphosate were found.” The authors continue, “The banks and the bed of the river system are almost all covered by concrete. The hydrological regime is natural and intermittent in […]

(Beyond Pesticides, March 15, 2024) Toxic pesticides harm all beings and ecosystems, including coral reefs. Large benthic foraminifera (LBF) are single-celled organisms found on reefs that face adverse metabolic impacts after exposure to the weed killer glyphosate and insecticide imidacloprid, according to a study published in Marine Pollution Bulletin. The study found that “even the lowest doses of the fungicide and herbicide caused irreparable damage to the foraminifera and their symbionts.” Beyond Pesticides reiterates our mission of banning toxic petrochemical pesticides by 2032 and that this goal applies to land and water exposure to pesticides. LBFs are typically used as bioindicators for coral health because they are found in substantial quantities and gathering data is not intrusive or damaging to reef health. Researchers in this study screened three different herbicides (one insecticide, one fungicide, and one herbicide) at three different concentration levels. The experiments were performed in six well-samples, each with 10mL of filtered artificial seawater and a singular LBF. The control plates are artificial seawater and the experimental plates include artificial seawater with the addition of three pesticides (imidacloprid, glyphosate, and tebuconazole). Each pesticide was applied at low, medium, and high doses to measure the direct impacts of each […]

(Beyond Pesticides, February 26, 2024) Beyond Pesticides today launched an action to stop a nationwide campaign by chemical manufacturers to shield themselves from liability cases filed by those who have been harmed by pesticide products. As widely reported, Bayer/Monsanto has been hit with numerous jury awards and settlements totaling billions of dollars for adverse health effects associated with their weed killer glyphosate (RoundupTM). After unsuccessfully seeking U.S. Supreme Court review of two of these cases, the industry is now pushing legislation in state legislatures that will shield them from future liability litigation. This is not the first time that the pesticide and toxic chemical industry has sought protection from the states after losing in the highest U.S. Court. After the Supreme Court upheld the right of localities to restrict pesticides more stringently than the U.S. Environmental Protection Agency and state regulatory agencies in Wisconsin Public Intervenor v. Mortier (501 U.S. 597, 1991), the industry went to every state legislature in the country to seek state preemption of their local jurisdictions’ authority to restrict pesticides. They were successful in putting state preemption laws in place in 43 states and have since added another.   Having failed in the courts, history is […]

(Beyond Pesticides, February 23, 2024) The latest string of billion-dollar plaintiff judgments against Bayer/Monsanto, the maker of Roundup™ with active ingredient glyphosate, does not yet signal a capitulation by Bayer or a win for public health or the environment in the United States. A jury award of $2.25 billion, the largest to-date, was handed down in Philadelphia in January. As Beyond Pesticides reported previously, Monsanto has a long history of challenging scientific findings on Roundup/glyphosate and evidence of harm to human health, the environment, and crops themselves (see resistant super weeds here and here), as it seeks to avoid liability claims by those suffering from cancer.  Bayer Looking to State Legislatures for Protection from Lawsuits  As result of its failure in quash lawsuits, Bayer has moved its case to state legislatures, where it is seeking the adoption of statutes that preempt liability claims by damaged parties.  As reported by Beyond Pesticides, a rash of state legislation has been introduced in Idaho, Iowa, Missouri, and Florida, which would block plaintiff liability claims when pesticide products, like Roundup, cause harm. The chemical industry pushes the notion that the registration of its pesticide products with the U.S. Environmental Protection Agency (EPA) is a […]
