(Beyond Pesticides, September 28, 2023) As the United States commemorates the 50th anniversary of the Endangered Species Act (ESA), there is a growing recognition that the planet faces an existential biodiversity crisis, with a rising number of species on the brink of extinction. In a collective effort to address threats to global biodiversity (i.e. diversity of all life), a coalition of environmental organizations including Beyond Pesticides, are sending an urgent letter to President Joe Biden. This letter, titled “Meeting the Challenges of the Biodiversity and Extinction Crisis Over the Next 50 Years,” calls for bold and comprehensive action to preserve our planet’s natural heritage for future generations. The ESA is celebrated as one of the most effective conservation laws globally, credited with preventing the extinction of 99 percent of listed species. Over the past five decades, the ESA has played a pivotal role in preventing these extinctions by safeguarding the most critically endangered species within biological communities. However, this concentration on highly threatened species often results in temporary solutions that may not comprehensively address the broader issue of biodiversity loss. The ESA establishes a framework to categorize species as “endangered” or “threatened,” granting them specific protections. While it is crucial […]

(Beyond Pesticides, September 19, 2023) Farmworkers in Paarl, South Africa took to the streets on Friday, September 8, demanding an end to the indiscriminate importation and use of pesticides, herbicides, and fungicides containing substances prohibited by the European Union (EU). This protest is part of a broader global trend of outcry against systemic issues of environmental racism that disproportionately burden communities with environmental and health risks.   Organized by the Women on Farms Project, the protesters marched to the headquarters of Bayer. The German pharmaceutical, biotechnology, and pesticide company, responsible for producing and exporting agrochemicals known to be toxic to ecosystem and human health, has previously faced multiple lawsuits, including a multimillion-dollar one linking their glyphosate weed killer products (Roundup®) to non-Hodgkin Lymphoma. At the Bayer office, the protesters presented a memorandum demanding an end to the importation and use of EU-prohibited substances.    Protesters sought to expose the hypocritical tactics European agrochemical companies use to sell products in developing nations, even when those products are deemed unsafe in their home countries. Numerous farmworkers, like victim-turned-activist Antie Dina, spoke out about their health issues from petrochemical exposure. In her talk, Dina emphasizes that, “… enough is enough, we do not want any […]

(Beyond Pesticides, September 15, 2023) The U.S. Environmental Protection Agency suspended the registration of the herbicide dimethyl tetrachloroterephthalate (DCPA) (also widely known as Dacthal), effective August 22, 2023 and leaves existing stocks (products containing DCPA manufactured before August 22) available on the market. The decision is one of a series of EPA attempts dating to 2013 to get more data from the manufacturer as the agency considers reregistration of DCPA. The suspension is toothless, however, since EPA did not totally close the book on this chemical. Six days before the suspension, EPA signed a settlement agreement with the sole manufacturer, AMVAC Corporation, to reinstate the registration upon receipt of the complete toxicological data—that is, animal and laboratory tests— needed to determine the chemical’s safety and how and where it can be used. DCPA is currently classified by EPA as a possible human carcinogen and has also been shown to be a thyroid hormone disrupter. DCPA is regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Pesticides are supposed to undergo reregistration every 15 years to take new science into consideration, but this process is glacial. Congress amended FIFRA in 1988 to speed up reregistration of products registered before 1984, and […]

(Beyond Pesticides, September 14, 2023) As we celebrate National Organic Month this September, it is the perfect time to reflect on why you should consider going organic. Do you try to buy organic food when you can? Are you looking for a way to reduce your and your family’s exposure to toxic pesticides? The benefits of choosing an organic lifestyle extend far beyond your diet or your own health. Beyond Pesticides is helping communities transition parks and public lands to organic land management. Here are some reasons why Beyond Pesticides believes in building organic communities: Why Go Organic? Health and Safety: Organic foods and parks are free from harmful pesticides, fossil-fuel-based substances, and toxic chemicals, making them safer and healthier for all ages. Visit Beyond Pesticide’s 40 Common Lawn and Landscape Chemicals page to learn more about the health impacts of pesticides in communities.

(Beyond Pesticides, September 7, 2023) During Organic Month, the importance of organic practices is brought into sharp focus by a study published in July in Environmental Health Perspectives, which emphasizes the importance of an organic diet and location to residues of pesticides in the body. The study finds urinary levels of the weed killer glyphosate significantly decrease through an organic diet for pregnant individuals living further than 0.5km (~1640ft) from an agricultural field. However, the study finds that adopting an organic diet among pregnant individuals living closer than 0.5km to an agricultural area does not significantly decrease glyphosate levels, indicating alternative sources of contamination outside of diet. Although past studies prove time and time again that an organic diet can reduce the levels of pesticides in the body, far too few studies investigate how the intervention of the organic diet can alter glyphosate levels among pregnant individuals living near or far from agricultural fields on which the herbicide is used. Furthermore, pesticides’ presence in the body affects human health, especially during vulnerable life stages like childhood, puberty, pregnancy, and old age. The study raises the complexity of fully tracking multiple exposures to glyphosate and other pesticides and the need for […]

(Beyond Pesticides, September 5, 2023) Lincoln County, Oregon  community members are fighting a plan announced by a private landowner to aerially spray 473 acres of clear-cut forest over the Beaver Creek watershed with a pesticide mixture containing carcinogenic glyphosate (commonly found in Roundup).  The aerial spraying is slated to take place approximately one mile from a water intake at Seal Rock Water District, which supplies water to 5,500 residents. Beyond the risks to human health, residents are concerned about the impacts on wildlife in the creek valley. Local advocates describe the area to include native wetland plants, birds, and fish, including the federally protected Coho Salmon and Marbled Murrelet, beaver, river otter, and roaming elk herds. Beavercreek is also a protected state natural area, where families paddle and walk along the state park marshlands.  Neighbors of Beaver Creek and the surrounding community are organizing phone banking, public art displays, and a petition urging Governor Tina Kotek to put a moratorium on the spray operation. One of the efforts displays the message “legalized poisoning of 5,500 people” through lights projected onto a basalt rock formation at Seal Rock State Park. The community has gathered over 2,000 petition signatures and over 100 […]

(Beyond Pesticides, August 31, 2023) A study published in Environmental Research finds glyphosate levels in the body adversely affect neurological health. Specifically, oral intake (e.g., eating contaminated foods), inhalation, and dermal exposure to glyphosate lowered cognitive function scores, heightened likelihood of severe depressive symptoms, and impaired auditory (hearing) function. Thus, this study provides some of the first evidence linking glyphosate exposure to specific neurological health outcomes among the general U.S. population, indicating the need for further studies on mechanisms driving neurotoxicity and the medical significance over time. Although this study is among the first to highlight specific neurological effects from glyphosate exposure among the general population, this study is not the first to identify potential neurotoxicity from glyphosate exposure. (Previous research cited below.) The ubiquity of glyphosate uses in agriculture—which leaves residues of the toxic chemical in food—and in public areas (e.g., parks, and walkways) may mean that exposures to it represent a significant risk factor for the disease. Glyphosate is already implicated or proven in developing numerous health anomalies, including cancer. The neurological system, including the brain, spinal cord, and a vast network of nerves and neurons, is responsible for many bodily functions—from sensation to movement. However, pesticides play various roles in […]

(Beyond Pesticides, August 29, 2023) A study published in Insect Biochemistry and Molecular Biology finds the widely used azole fungicide, tebuconazole, has damaging impacts on the redox homeostasis (the process of maintaining balance between oxidizing and reducing reactions) and fatty acid composition in honey bees’ brain via oxidative stress. Acute, field-realistic sublethal exposure to tebuconazole decreased the brain’s antioxidant capacity, key antioxidant defense systems, and oxidative degradation and alteration of lipids (fats) in the brain. Thus, this study adds to the scientific literature on the adverse effects of chemical exposure on pollinator health, especially in sublethal concentrations. Degenerating cognitive skills can threaten honey bee survivability, decreasing colony fitness and individual foraging success. Much research attributes the decline of insect pollinators (e.g., commercial and wild bees and monarch butterflies) over the last several decades to the interaction of multiple environmental stressors, from climate change to pesticide use, disease, habitat destruction, and other factors. Pollinator declines directly affect the environment, society, and the economy. Without pollinators, many plant species, both agricultural and nonagricultural, will decline or cease to exist, as U.S. pollinator declines, particularly among native wild bees, depress crop yields. In turn, the economy will take a hit, since much of the economy (65%) depends upon the […]

(Beyond Pesticides, August 22, 2023) A U.S. Geological Survey (USGS) and National Park Service collaborative survey report finds a harmful mixture of pollutants, including pesticides, pharmaceuticals, caffeine, methylparaben, algal toxins, and fecal and parasitic bacteria, in Pipestone Creek at Pipestone National Monument in Minnesota, U.S.— adding to evidence of widespread pesticide contamination in waterways across the U.S. Pesticide contamination in waterways is historically commonplace. A 1998 USGS analysis revealed pesticides are commonly found in all U.S. waterways, with at least one pesticide detectable. Thousands of tons of pesticides enter rivers and streams around the US from agricultural and nonagricultural sources, which contaminate essential drinking water sources, such as surface water and groundwater. As the number of pesticides in waterways increases, it has detrimental impacts on aquatic ecosystem health, especially as some pesticides work synergistically with others to increase the severity of the effect. Reports like these are significant tools for determining appropriate regulatory action to protect human, animal, and environmental health.  The survey collected water samples from Pipestone Creek, the pipestone quarries, and Winnewissa Falls, all of which are on the U.S. Environmental Protection Agency’s (EPA) list of impaired waters for turbidity (reduced water clarity) and fecal coliform bacteria (E. coli). Turbidity and fecal coliform […]

(Beyond Pesticides, August 23, 2023) Researchers are investigating a cutting-edge method to identify the impact of pesticides on reproductive health—shrinking the wait time from months to weeks. Scientists at the University of California, Davis, are developing a method for identifying harmful chemicals in pesticides with the help of glowing fish. This scientific breakthrough could revolutionize pesticide research and help prevent long-term health problems caused by exposure to these chemicals.  Pesticide exposure can cause acute and long-term health problems for the human endocrine system, the hormone system that regulates many biological processes from reproduction to blood sugar, growth, and more. Beyond Pesticides has written about the connections between EPA-registered pesticides and involuntary abortions, reproductive cancers, pregnancy loss, early-onset puberty, and more.   The American Academy of Pediatrics (AAP) has expressed concern over the limited or missing data regarding the health effects of pesticides and food additives on infants and children, who are more vulnerable to chemical exposures. AAP has identified several compounds as being of particular concern, including bisphenols, which are commonly used in the lining of metal cans; phthalates, which are used in adhesives and plasticizers; nonpersistent pesticides, which have been addressed in a previous AAP policy statement; perfluoroalkyl chemicals (PFCs), […]

(Beyond Pesticides, August 14, 2023) Marijuana regulators in the state of Washington issued administrative holds on 18 licenses due to pesticide-contaminated marijuana, forcing producers and processors to cease operations until now. This shutdown of legal marijuana businesses serves as a window into a broader historical backdrop of pesticide issues within the marijuana industry. Within Washington, pesticide concerns have been growing since a study in 2018 of legal marijuana farms in the state had 84.6% (of 26 samples) with significant quantities of pesticides including insecticides, fungicides, miticides, and herbicides. Last year, a national study identified a list of contaminants in 36 states and the District of Columbia and found 551 pesticides within cannabis products. For over a decade, Beyond Pesticides has sounded the alarm about the highly-concentrated levels of pesticides in marijuana products, calling on state officials to require organic marijuana, especially in the context of medical marijuana. The absence of federal regulations for pesticides in cannabis production has raised significant concerns about exposure risks for recreational and medicinal use, exposure risks to workers, and potential environmental contamination impacting wildlife. Since marijuana is classified as a Schedule 1 narcotic under the Controlled Substances Act, the EPA does not regulate pesticides in […]

(Beyond Pesticides, August 11, 2023) Reinforcing earlier findings, a systematic review published in Chemosphere finds the popular herbicide glyphosate and its formulations (glyphosate-based formulations-GBF) exhibit five out of the ten key characteristics (KC) of carcinogens (cancer-causing chemicals). Specifically, glyphosate exhibits strong evidence of genotoxicity, epigenetic alterations (heritable changes in gene expression), oxidative stress, chronic inflammation, endocrine disruption, and disturbs gut microbiota implicated in lymphomagenesis (growth and development of lymphoma). Although organizations like the International Agency for Research on Cancer (IARC) designate glyphosate as a probable human carcinogen, and scientific literature supports the findings on these adverse effects purported by glyphosate, the chemical remains on the U.S. market in various formulations. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, not just Bayer’s (formerly Monsanto) Roundup®. 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 […]

(Beyond Pesticides, August 8, 2023) A study published in PLOS ONE finds a pointed, positive association between chronic kidney disease (CKD) of unknown origins (CKDu) and the use of indoor pesticides. Longer exposure times have an especially detrimental impact on kidney function, even among individuals without underlying diseases like diabetes mellitus and hypertension. The innovation of this study’s purpose highlights the lack of exposure-related studies on kidney health outcomes associated with indoor pesticide use. Although CKD risk increases with age and is associated with other health factors like smoking, heart disease, and diabetes, cases without clear causes are increasingly common, indicating that environmental factors are likely playing a role. Over six million people in the U.S. have kidney disease (i.e., nephritis [kidney inflammation], nephrotic syndrome [improper protein filtration], and nephrosis). Although many studies find an association between exposure to outdoor environmental contaminants like pesticides and CKD, the association between CKDu and indoor pesticides—whose uses are more commonly concentrated in homes— remains unclear. Therefore, studies like this highlight the need for comprehensive information regarding co-occurring exposure patterns and disease prevalence that can have global implications.  The study notes, “Previous research has highlighted the potential harm of pesticides on kidney function, particularly in outdoor uses. Our findings raise […]

(Beyond Pesticides, August 4, 2023) The results of an Australian study published in Nature strike a contrast between land and water contamination with pesticide active substances (PAS), highlighting contamination as pesticides are transported through waterways.  The study results on water transport raise serious contamination issues. Only about one percent of the pesticides entering rivers degrade, so that long stretches of waterways and the oceans suffer the direct impact of a pesticide’s active ingredient. The lack of degradation also means that water organisms are being exposed to levels of pesticides exceeding many of the regulatory threshold limits set by governments. Although observation data are highly variable, the authors note that measured concentrations of pesticides in some river reaches of North America, East Asia and Europe exceed one or more regulatory threshold limits “at least once a year.” Further, the pesticides can bioaccumulate at each level of the aquatic food web, which can multiply concentrations by a thousand or more in the highest trophic levels, according to the study authors. The study finds that more than four-fifths of PAS are degraded in the soil, leaving about 10 percent of the original chemical in the soil as residue. Nearly half of that residues […]

(Beyond Pesticides, August 1, 2023) The U.S. Environmental Protection Agency has announced that it is publishing a decade’s worth of pesticide incident data in a searchable database that will be updated on a monthly basis. The Incident Data System (IDS), with poisoning reports generated mostly from chemical manufacturers, states, a national hotline, and poison control centers, offers information on reported pesticide exposures from accidental poisoning of pets, wildlife, and humans, to pesticide drift, noncompliance, and other pesticide incidents that may be associated with product uses in compliance with label instructions. Tracking this incident data is essential to understanding the risks and damages associated with pesticide use.   The bulk of the data on incidents is from consumer reports to chemical manufacturers. Chemical companies are required under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), Section 6(a)(2) to report incidents: “If at any time after the registration of a pesticide the registrant has additional factual information regarding unreasonable adverse effects on the environment of the pesticide, the registrant shall submit such information to the Administrator.” The determine of threshold number of incidents required to be reported as a pattern of “unreasonable adverse effects” is left to the manufacturers to determine. Through […]

(Beyond Pesticides, July 28, 2023) A study published in Science of the Total Environment finds glyphosate can adversely impact sensory and cognitive processes in bumblebees (Bombus terrestris). Glyphosate exposure impairs bees’ learning of aversive stimuli like electric shocks paired with specific color discrimination. Additionally, the pesticide reduces attraction to UV (ultraviolet) light, specifically the color blue, and temporarily impacts locomotion and phototaxis (movement in response to light). These impairments to sensory and cognitive processes render foraging difficult for these glyphosate-exposed pollinators and vulnerable to unavoidable predators. The study highlights that symptoms of widespread chemical exposure may reduce foraging efficiency and adversely affect ecosystems, especially those dependent on insect pollinators.  Pollinator decline directly affects the environment, society, and the economy. Without pollinators, many plant species, both agricultural and nonagricultural, will decline or cease to exist as U.S. pollinator declines, particularly among native wild bees, limit crop yields. In turn, the economy will take a hit, since much of the economy (65%) depends upon the strength of the agricultural sector. As the science shows, pesticides are one of the most significant stressors for pollinators. In a world where habitat loss and fragmentation show no sign of abating, scientists have concluded that the globe cannot afford to continue […]

(Beyond Pesticides, July 26, 2023) An exploratory study published in Environment International adds to the many studies demonstrating residential prenatal pesticide exposure can result in adverse birth outcomes. Residential exposure to five active pesticide ingredients (Ais) fluroxypyr-meptyl, glufosinate-ammonium, linuron, vinclozolin, and picoxystrobin has adverse effects on gestational age (GA), birth weight (BW), mortality after birth, child’s sex, premature development, low birth weight (LBW), small for gestational age (SGA), and large for gestational age (LGA). Pesticides’ presence in the body has implications for human health, especially during vulnerable life stages like childhood, puberty, pregnancy, and old age. Pesticide exposure during pregnancy is of specific concern as health effects for all life stages can be long-lasting. Birth and reproductive complications are increasingly common among individuals exposed to environmental toxicants like pesticides. The Centers for Disease Control and Prevention (CDC) reports birth defects are the leading cause of infant mortality, with one in every 33 infants born with an abnormality that results in death. Therefore, studies like this can help government and health officials safeguard human health by assessing adverse effects following prevalent chemical exposure.  Using a Dutch birth registry from 2009 to 2013, the researchers selected pregnant mothers over 16 years who were living in non-urban areas (who […]

(Beyond Pesticides, July 17, 2023) Students of environmental policy quickly learn that the most meaningful change to protect health and the environment begins with action in local communities. The challenge now is to preserve the rights of communities under federal law to restrict pesticides and advance local protections through the adoption of eco- and health-friendly, organic land management practices. As is known from history, with the leadership of local communities, the states and the federal government will follow. History of Action in Communities and States Major actions on the banning or restricting of specific pesticides over the last seven decades—from DDT (in Michigan and Wisconsin), 2,4,5-T [1/2 of Agent Orange] (in Oregon [read A Bitter Fog]), to chlordane (New York)—began with calls from the grassroots about dying wildlife to elevated cancer and miscarriage rates and other diseases. But, these chemical incidents (which continue to today with similar campaigns, but different chemical names like glyphosate, imidacloprid (neonicotinoids), and others), launched broader community-based efforts to curtail overall pesticide use—stop drift, runoff and other nontarget exposure—and require organic-compatible practices. Tracing the history—from Mendocino County, CA to Lincoln County, OR, to Casey, WI (upheld by the U.S. Supreme Court), to Montgomery County, MD, to […]

(Beyond Pesticides, June 14, 2023) The exoskeleton of the black soldier fly (BSF; Hermetica illucens) has the potential to be an effective organic fertilizer. A study in the journal Agriculture, Ecosystems & Environment highlights the positive impacts on plant size, flower count, seed production, appeal to pollinators, and resilience to herbivory that the fly’s molted exoskeleton (or exuviae) can have when used as a soil supplement. The use of insect exuviae as an organic alternative to harmful synthetic fertilizers is an important step toward an environment free from chemical contaminants, and BSF are uniquely equipped to contribute to a regenerative organic agricultural system. The study set out to determine the impacts of BSF exuviae on plant growth, resilience to herbivory, and pollination. The scientists divided black mustard plants into four different treatment groups: 1) grown in soil amended with BSF powdered exuviae; 2) control group planted in chemically-treated (conventional) soil; 3) grown in amended soil and subjected to increased herbivory from caterpillars (Pieris brassicae) and aphids (Brevicoryne brassicae); and 4) planted in conventional soil and subjected to increased pest exposure. Scientists measured plant growth, flowering status, seed production, herbivore abundance, and pollinator activity. After three weeks, the supplemented soil grew […]

(Beyond Pesticides, July 11, 2023) A study published in Parkinsonism & Related Disorders finds high exposure to household pesticides increases the risk of developing Parkinson’s disease (PD) two-fold. There is a multitude of epidemiologic research on Parkinson’s disease demonstrating several risk factors, including specific genetic mutations and external/environmental triggers (i.e., pesticide use, pollutant exposure, etc.). However, several studies find exposure to chemical toxicants, like pesticides, has neurotoxic effects or exacerbates preexisting chemical damage to the nervous system. Past studies suggest neurological damage from oxidative stress, cell dysfunction, and synapse impairment, among others, can increase the incidence of PD following pesticide exposure. Despite the widespread commercialized use of household pesticides among the general population, few epidemiologic studies examine the influence household pesticides have on the risk of PD, although many studies demonstrate the association between PD onset via occupational (work-related) pesticide exposure patterns. Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans living with PD and about 50,000 new diagnoses annually. Alzheimer’s ranks first. The disease affects 50 percent more men than women, and individuals with PD have a variety of symptoms, including loss of muscle control and trembling, anxiety and depression, constipation and urinary difficulties, dementia, and […]

(Beyond Pesticides, July 10, 2023) [Editor’s note to readers: The local, democratic decision-making process to adopt restrictions on pesticide use, now under attack in Congress, has historically been critical to the protection of health and the environment when federal and state governments have failed in their responsibility. This local democratic right has not only protected communities where action is taken, but it has driven state and federal policy to do better—to do what is required in a society that cares about a sustainable future. While federal and state pesticide policy sets a floor on minimum protections and rights, there is nothing more important than nurturing the local democratic process to increase and strengthen protections that elude government agencies that are unduly influenced by the powerful chemical industry. As we face existential crises of health threats, biodiversity collapse, and the climate emergency resulting from gridlock in legislative bodies that ignore the scientific facts documenting harm and solutions that are within our grasp, there is nothing more important than empowering local communities to embrace meaningful changes that eliminate pesticides and adopt organic land management practices. These changes embrace nature and ecosystem services. While the federal regulatory process is skewed toward assumptions of […]

The introduction of the Agricultural Labeling Uniformity Act in the U.S. House of Representatives, expected to be a part of the Farm Bill negotiations, is raising the specter (yet again) of undermining local and state authority to protect the health of their residents from pesticides—effectively overturning decades of Supreme Court precedent.

(Beyond Pesticides, June 30, 2023) Exposure to environmentally relevant concentrations of the herbicide glyphosate (GLY) has the potential to induce heart damage (cardiotoxicity) through the aging (senescence) of cells and a reduction of the number of rapidly increasing (proliferating) cells, according to a study published in Ecotoxicology and Environmental Safety. Specifically, glyphosate induces toxic effects on cardiomyocytes (cardiac muscles) responsible for contractions that pump the blood. Cardiovascular (heart) disease (CVD) is one of the leading causes of death in the U.S., with approximately 700,000 people dying annually of heart disease, equating to 25% of all U.S. deaths. Additionally, heart conditions are one leading cause of disability in the U.S. Research has shown that environmental pollutant exposure can increase the risk of developing cardiovascular disease, including stroke, heart attack, heart failure, atrial fibrillation, and cardiac arrest. Considering chemical exposure exacerbates adverse disease effects, reviews like these highlight the significance of evaluating synergism between diseases and toxic chemicals to safeguard human health. The study warns, “Our findings offer important information regarding the potential mechanisms of GLY cardiotoxicity toxicity. Notably, our study provides new insights into the relationship between GLY and senescence. Cardiac dysfunction of GLY to non-target organisms need to be noted in future study. Our study raises concerns about the […]
