(Beyond Pesticides, June 2, 2023) Scientists have identified 97 different types of pesticides and flame retardants in primate fecal samples, recently reporting their results in the journal Biology Letters. In Uganda’s Kibale National Park, researchers studied the chemical exposure of four species of primates (chimpanzees, Ugandan red colobus, olive baboons and red-tailed monkeys), adding to previous research on the subject. The chemicals demonstrate a measurable effect on primate growth and development, sparking considerable unease as to the future health of these critical species. This study shows how even within a protected national park, wildlife species are at risk from chemical pollution. According to advocates, the use of dangerous pesticides and flame retardants, therefore, must be entirely stopped in order to protect the future viability of wildlife species.  Scientists collected a total of 71 fecal samples from the four chosen species to measure levels of chemicals and hormones in a noninvasive manner. After sample analysis, researchers highlight three main groups of chemical pollutants: organochlorine pesticides (OCPs), brominated flame retardants (BFRs), and organophosphate esters (OPEs). Although in a protected area, wildlife species encounter humans through tourism, research, and human development surrounding the park. As these pesticides are so prevalent in areas of […]

(Beyond Pesticides, May 31, 2023) A study published in Chemosphere supports accumulating scientific research confirming that prohibited and current use pesticides are readily detectable in the human placenta. All pregnant women experience exposure to a mixture of complex pesticides like DDT (prohibited organochlorine pesticide [OCP]) and chlorpyrifos (current use organophosphate [OP]), with concentrations high enough to increase possible adverse health risks to the fetus through a placental transfer of chemicals. Prenatal development in the intrauterine environment is one of the most vulnerable periods of exposure, as the fetus is most susceptible to the harmful effects of chemical contaminants. Many studies indicate that prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. Given the over 1,300 research studies that demonstrate the link between pesticide exposure and general health effects, studies like this can help government and health officials identify how pesticides’ impact on the body elevates health concerns, especially for future and developing generations. The authors note, “This study highlights the urgent requirement for implementing alternative pest-control methods in agriculture, involving a reduction of chemical pesticides application. Due to the vital role of the placenta in fetal development and its non-invasive sampling, this kind of […]

(Beyond Pesticides, May 30, 2023) On Endangered Species Day, May 19, the U.S. Environmental Protection Agency (EPA) revealed an unfortunate degree of hypocrisy in its claims to protect endangered species from pesticides. Tell EPA and Congress that dwindling biodiversity is an existential crisis that requires removing serious threats posed by pesticides. EPA announced that it “is publishing a group of StoryMaps to raise public awareness about protecting endangered species from pesticides.” It continues, “Through its Vulnerable Species Pilot, EPA has been identifying endangered species that are vulnerable to pesticides, developing mitigations to protect them from pesticide exposure, and will apply the mitigations to many types of pesticides.” However, pesticide use is a major cause of declining biodiversity, which is manifested in extinctions, endangered species, and species vulnerable to environmental disturbances—including climate change, habitat fragmentation, and toxic chemicals. If EPA is serious about protecting biodiversity, it must look first at the ways it has created the crisis in the first place. Studies upon studies upon studies show that pesticides are a major contributor to the loss of insect biomass and diversity known as the “insect apocalypse,” particularly in combination with climate change. Insects are important as pollinators and as part of […]

(Beyond Pesticides, May 26, 2023)The use of pesticides in agriculture, transportation, and domestic settings has created a disastrous conflict for the human species. Two irreconcilable facts confront humans as they try to adapt to the consequences of earlier choices: One, industrial civilization came to believe that because some insects, fungi, and other organisms like to eat the same plants humans eat, humans can kill them with impunity; two, because some insects and other organisms are necessary to the health and reproduction of plants, humans need to protect them. At no point in history have people acknowledged that it is very difficult to kill the “bad” actors while protecting the “good” ones. There are not really two sides to the biological fact; rather, pesticides and biodiversity meet each other on a single plane, like a Möbius strip. Among the most dire effects of pesticides are their ruination of pollinators. Bees spring to mind as our primary pollinators, but they are by no means the only ones. Butterflies, often regarded as mere ornamental additions to a landscape, are actually significant pollinators themselves. Monarchs pollinate many flowers, including calendula and yarrow. Other butterflies pollinate dill, celery, fennel, cilantro, lettuce, peas, and basil, among […]

(Beyond Pesticides, May 25, 2023) A review of scientific literature published in the Journal of Endocrinological Investigation demonstrates exposure to past and current-use endocrine-disrupting chemicals (EDCs), like pesticides, have a long history of severe adverse human health effects. Endocrine disruptors are xenobiotics (i.e., chemical substances like toxic pesticides foreign to an organism or ecosystem) present in nearly all organisms and ecosystems. The World Health Organization (WHO), European Union (EU), and endocrine disruptor expert (deceased) Theo Colborn, Ph.D., classify over 55 to 177 chemical compounds as endocrine disruptors, including various household products like detergents, disinfectants, plastics, and pesticides. Endocrine disruption can lead to several health problems, including hormone-related cancer development (e.g., 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 infertility, among other health issues. The review notes, “New evidence supports the role of other EDCs as possibly carcinogenic and pregnant women should avoid risk area and exposure. The relationship between EDCs and cancer supports the need for effective prevention policies increasing public awareness.” The review examines the relationship between EDCs and various hormone-mediated various (i.e., breast, prostate, testicle, ovary, and thyroid) to determine the carcinogenicity of the chemicals and their impact on public […]

(Beyond Pesticides, May 23, 2023) Scientists have developed a nontoxic method to deter rodents from feeding on freshly planted seeds, publishing the approach in the journal Nature Sustainability this month. The new tactic, which confuses mice through olfactory misinformation, has the potential to significantly reduce the use of hazardous rodenticides in farming operations. The approach comes at a time of increased scrutiny around rat poisons, specifically second-generation anticoagulant rodenticides (SGARs), which can result in the secondary poisoning of predators that eat poisoned rodents. Researchers set out with the intent of finding a safe alternative to rodenticides that can effectively reduce pest damage without the need for hazardous interventions. “A simpler approach to pest damage is to manipulate decisions making by problem animals and disrupt their ability to find at-risk foods,” the study indicates. Contrary to the promises of the pesticide industry that its products are ‘silver bullets’ for pest management, the authors propose weaponizing misinformation over brute force by fooling mice into thinking their sought-out food source is not there. Mice and other rodent foragers most often rely on scent and odor to determine where food is located. In the context of this study, farmers plant wheat seeds along rows, […]

(Beyond Pesticides, May 22, 2023) Since most of the domestically produced fresh produce we eat comes from California, what happens in the state is of concern to most consumers. The California Department of Pesticide Regulation (DPR) has made minor adjustments to its proposal to 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 at the California Office of Environmental Health Hazard Assessment—charged with establishing safe limits of exposure and enforcing Prop 65—say is safe, highlights the dangers to which farmworkers are routinely exposed. It is outrageous that 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. You may have commented on this early in the year, and now we need to follow up with a strong message to protect those who harvest the nation’s food.  Tell EPA, Congress, and CDPR to cancel the registration of all toxic soil fumigants and encourage organic alternatives. 1,3-D is a pre-plant soil fumigant registered for use on soils to control nematodes. It is allowed on all crops and is often used with chloropicrin, another highly toxic […]

(Beyond Pesticides, May 19, 2023) Agricultural intensification is the leading factor driving declines in bird populations across Europe, according to research published in the Proceedings of the National Academy of Sciences (PNAS) this week. Among all potential anthropogenic impacts, agricultural intensification, in particular pesticide and fertilizer use, was found to be more dramatic than forest alterations, urbanization, and climate change. “I don’t think a study has looked at all these factors in one go, in such a sophisticated fashion, correcting for one variable alongside another; and it comes out with a very clear message,” lead author Richard Gregory, PhD, of UK nonprofit The Royal Society for the Protection of Birds, told The Guardian. Researchers utilized data dating back to the early-1980s, including annual bird surveys and national and supranational analyses, as well as information on land use cover, farm inputs, and temperature changes within the time frame. Bird habitat and ecological traits were also considered in the context of declines, and a statistical analysis aided researchers in capturing trends over time. Results confirmed that birds are overall experiencing significant declines in Europe, with data recording 25% losses in bird abundance since 1980. However, certain groups of birds are faring worse […]

(Beyond Pesticides, May 18, 2023) A study published in Food and Chemical Toxicology finds pesticide residues in beehive products pose a safety risk from dietary consumption. Beehive products (i.e., bee bread, propolis, beeswax, and royal jelly) from beekeeping or apiculture are said to have nutraceutical (health and medicinal benefits) properties. However, a wide range of pesticide residues (i.e., tau-fluvalinate, coumaphos, chlorfenvinphos, chlorpyrifos, and amitraz), especially acaricides for killing ticks and mites in hives, may accumulate in beehive products up to concentrations that pose a potential health risk. Environmental contaminants like pesticides are ubiquitous in the environment, with 90 percent of Americans having at least one pesticide compound in their body. Many of these chemical compounds remain in soils, water (solid and liquid), and the surrounding air at levels exceeding U.S. Environmental Protection Agency (EPA) standards. Therefore, individuals still encounter pesticide compounds at varying concentrations, adding to the toxic body burden of those harmful chemicals currently in use. The research methodology includes a review of the scientific literature on pesticide contamination in hive products and a dietary risk assessment. The risk assessment calculation uses scientific studies to determine the recommended daily intake values and concentration data. Researchers compare exposure values in products to health-based guidance, determining the potential acute and […]

(Beyond Pesticides, May 17, 2023) British biotechnology company Oxitec is withdrawing its application to release billions of genetically engineered mosquitoes in California, according to a recent update from the California Department of Pesticide Regulation. The withdrawal is a victory for environmental and health campaigners concerned about the release of a novel mosquito that the U.S. Environmental Protection Agency (EPA) had previously authorized under an “experimental use” permit. “Genetically engineered mosquitoes are an environmental justice issue for Tulare County residents who should not be human experiments,” said Angel Garcia, codirector of the statewide coalition Californians for Pesticide Reform and Tulare County resident in a press release. “We are already impacted by some of the worst pollution problems in the state and deserve prior informed consent to being part of an open-air biopesticide experiment. Ahead of any future proposal for genetically engineered insects, DPR needs to have robust regulations in place that protect community members, and meaningful, inclusive public participation in any decision making.”     Oxitec began releasing its GE mosquitoes over a decade ago, first introducing the insects in the Brazilian town of Itaberaba. The company has made efforts to launch its mosquitoes in the United States, likely as a way […]

(Beyond Pesticides, May 15, 2023) Say “legacy contaminant” or “forever chemical” and most people today think “PFAS” (perfluoroalkyl substances), but PFAS are just the latest persistent toxic chemicals recognized as presenting an alarmingly difficult cleanup problem. Fortunately, steps are being taken by governments and businesses to eliminate use of PFAS. (Organic farmers concerned about the integrity of their products have been leaders in these efforts.) Although government officials often devote considerable energy and resources to cleaning up contamination, the continued manufacturing of these chemicals and their release into the environment creates a futile situation. The U.S. is a signatory to the 2001 Stockholm Convention, which provides an international framework for moving persistent organic pollutants out of commerce, but the U.S. Senate never ratified it.     Ask your Senators to ratify the Stockholm convention. Tell EPA that persistent toxic pesticides must be considered to pose an “unreasonable risk to the environment under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA),” which must result in cancellation of their registrations.  PFAS contamination is just the latest chapter of a very old story. Legacy contamination of our bodies and the environment is partly a result of a slow piecemeal approach to eliminating these toxic chemicals. […]

(Beyond Pesticides, May 12, 2023) With the growth of chemical-intensive land management over the last century, the world has been held captive by pesticide companies. For part of that time, it could be said the modern society has suffered from Stockholm Syndrome, a theory about abusive relationships in which one party exerts power over the other using threats, fear, and lies and the victim comes to depend on the perpetrator emotionally. During the so-called “Green Revolution” (circa 1945-1985), the world came to depend on vast amounts of fertilizers and herbicides, insecticides, and fungicides. Many people believed that food, clothing, and shelter made from naturally-occurring materials such as fruit, flax and wood could not be provided to the world without pesticides. It seemed that science and commerce could indefinitely raise the standard of living around the world, perhaps leading to world peace. This is not what happened. Soon observers noticed the harmful effects of many pesticides, including their persistence in the environment, their tendency to accumulate in the bodies of humans and wildlife, and their influence on the risk of contracting many diseases, from cancer to asthma—not to mention the Darwinian inevitability of pest resistance. By the turn of the 20th […]

(Beyond Pesticides, May 11, 2023) A study published in NeuroToxicology finds occupational (work-related), chronic exposure to pesticides increases risk factors of epilepsy, a neurological disorder causing unprovoked, reoccurring seizures. Mounting evidence over the past years shows that chronic exposure to sublethal (low) levels of pesticides can cause neurotoxic effects or exacerbate preexisting chemical damage to the nervous system. Although the mechanism by which pesticides induce disease development remains unclear, this study suggests environmental pesticide exposure increases seizure risk through mechanisms at molecular or subcellular levels. Approximately 3.4 million individuals in the U.S. live with epilepsy, and mortality from this disorder is rising nationwide. Over 300 environmental contaminants and their byproducts, including pesticides, are chemicals commonly present in human blood and urine samples and can increase neurotoxicity risk when crossing the brain barrier. Considering half of all epilepsy etiologies (causes) are of idiopathic (unknown) origins, studies like this highlight the importance of understanding how consistent chemical exposure can impact long-term health and disease prognosis. The study notes, “[The] approach to a real-world exposure scenario to pesticides in a large agriculture area over 17 years; […] can be linked to the novel approaches proposed for simulating real-life exposures, thus contributing to a better understanding of the real-life risk associated with long-term […]

(Beyond Pesticides, May 8, 2023) The Farm Bill in Congress covers many areas—ranging from the supplemental nutritional assistance program (SNAP) to trade—and the pesticide industry would like to insert a provision that takes away (preempts) local authority to restrict pesticide use—which would undercut the local democratic process to protect public health and safety. Even if communities are not now regulating toxic pesticides, we do not want to close the door on future action, as communities take on petrochemical pesticide and fertilizer use that is contributing to health threats, biodiversity collapse, and the climate emergency.    Part 1: Tell your local officials to sign onto a letter opposing the preemption language. Part 2: Tell your U.S. Representative and Senators to support communities by opposing anti-democratic preemption language in the 2023 Farm Bill.  As Congress drafts the 2023 Farm Bill, there is an opportunity for many topics—good and bad—to be introduced. Dating back to Franklin D. Roosevelt’s New Deal of the 1930s, which addressed threats posed by the Great Depression and drought, the Farm Bill is an omnibus bill passed every five years. It is designed to secure a sufficient food supply, establish fair food prices for both farmers and consumers, and protect […]

(Beyond Pesticides, May 5, 2023) Low level exposure to pyrethroid insecticides found in common pesticide brands like RAID and ORTHO result in neurodevelopmental damage to laboratory animals, reinforcing evidence of harm found in epidemiological studies on human exposure to these chemicals. According to research published in PNAS Nexus, mice exposed to the pyrethroid deltamethrin displayed atypical behavior similar to humans with developmental disorders. “We are not saying these mice have autism or that they have ADHD. That’s not the goal here,” said James Burkett, PhD, study coauthor and assistant professor of neuroscience in the UToledo College of Medicine. “What we are saying is that something in their brain has been altered by this exposure and it’s resulting in the same kinds of behaviors that we see in children with autism.” Scientists arrived at this determination by exposing a group of mouse mothers to consistent low levels of deltamethrin in their food during preconception, pregnancy, and lactation. The study notes that the amount of pesticide provided was “well below the benchmark dose for regulatory guidance.” A separate control group was given no pesticide in its food. Offspring from the female mice were then put through behavioral tests on social behavior, restrictive […]

(Beyond Pesticides, May 4, 2023) One of the most widely used insecticides in California, Intrepid 2F, contains harmful levels of per- and polyfluoroalkyl substances (PFAS), or “forever chemicals,” according to a report by the Center for Biological Diversity (CBD) and Public Employees for Environmental Responsibility (PEER). In fact, 40 percent of pesticide products in the report tested positive for high levels of PFAS. PFAS are common in non-stick cookware, cleaning/personal care products, food packaging, and other consumer products. However, these compounds are also in pesticide products. Despite evidence on the dangers of PFAS stretching as far back as the 1950s, federal agencies sat by the sidelines as the plastics industry continued adding the material to new products. From widespread presence in farm fields and sewage sludge to contaminated water bodies throughout the U.S., PFAS has made its way into the environment and our bodies. PFAS are even present in remote environments like the Arctic, Antarctica, and Eastern European Tibetan Plateau. A study published in 2020 identified PFAS as common products to which Americans are exposed daily. The U.S. Centers for Disease Control and Prevention (CDC) determined that 98% of Americans have some level of PFAS in their bloodstream, with studies reporting PFAS compounds are detectable in infants, children, and pregnant women. With […]

(Beyond Pesticides, May 2, 2023) On April 20, the European Commission’s new rules on endocrine disrupting chemicals took effect. Called “Classification, Labelling & Packaging” (CLP), the rules create four new hazard categories for endocrine disruptors. The categories range from “suspected of causing” or “may cause” endocrine disruption in the environment to “suspected of causing” or “may cause” endocrine disruption in humans. After a transition period, users will have to indicate on labels and packaging if a substance falls into any of the hazard classes. All actors in the supply chain are obligated to provide the information to every downstream participant. The  new CLP rules, implementing a 2022 measure adopted by the European Commission and then the European Parliament, also specify a minimum font size for the hazard information and for the first time include standards for labeling in online commerce and in places where customers use refillable containers to transport, store, and use the chemicals. According to the EU Directorate-General for the Environment: “The new hazard classes are the result of extensive scientific discussions and will provide easier access to information to all users of such chemicals, notably consumers, workers and businesses. They allow further action to address and mitigate […]

(Beyond Pesticides, May 1, 2023) The sheer number of different chemicals in the nation’s waterways and thus potential for toxic mixtures presents significant risks to health and the environment. However, the range of pesticides and the widespread contamination across the country would not be as fully uncovered without the work of the U.S. Geological Survey (USGS). Research conducted by USGS and the U.S. Environmental Protection Agency (EPA) on urban runoff across the country in 2019 found 215 of 438 sampled toxic compounds present in the water. The toxic soup in many U.S. waterways is unsustainable and threatens the foundation of many food chains. Imbalances in aquatic environments can ripple throughout the food web, creating trophic cascades that further exacerbate health and environmental damage. The data on water contamination has become one of the compelling reasons to abandon reliance on toxic chemicals in favor of organic land management to eliminate these threats. Tell Secretary of Interior Deb Haaland to expand USGS mapping of pesticide use and monitoring of waterways. Tell EPA Administrator Michael Regan that pesticides shown to contaminate rivers and streams must be banned. The USGS Water Resources Mission Area (WMA) researches pesticide use, trends in pesticide occurrence in streams, concentrations […]

(Beyond Pesticides, April 28, 2023) A study published in Science of The Total Environment finds agricultural communities encounter chronic and measurable pesticide exposure regardless of seasonal pesticide applications. Several biomonitoring studies demonstrate people living adjacent to or within agricultural areas often experience elevated levels of organophosphate (OP) insecticides, even while not working directly with OPs. Six dialkyl phosphate (DAP) metabolites (breakdown products) of OPs persist in urine during the spraying and non-spraying seasons. Despite 75 percent of OPs metabolizing into one or more of the six DAPs and excreting within six to 24 hours after exposure, the consistent levels of DAPs in urine highlight continuous exposure beyond regular seasonal pesticide applications. OP 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 and, as this study shows, residues are consistently present in human and animal urine, as well as blood, tissues, and milk. Considering 90 percent of Americans have at least one pesticide compound in their body, primarily stemming from dietary exposure, including food and drinking water, advocates maintain that current restrictions on their use must adequately detect and assess total chemical contaminants. The study notes, “We suggest that among agricultural communities that experience […]

(Beyond Pesticides, April 26, 2023) Organic methods of honey bee management are just as or more effective than conventional, chemical-intensive management systems, according to research published this month in the journal Scientific Reports by a team of Penn State scientists. This finding is important as managed pollinators continue to be under stress primarily from pesticide exposure, but also other factors, such as disease, pests, climate change, and habitat loss. In this context, beekeeping management practices can mean the difference between a colony thriving, surviving, or declining. “Beekeeping management is a key aspect of honey bee health because it can help mitigate some of the negative effects caused by these stressors,” said study co-author Robyn Underwood, PhD, of Penn State Extension. “For example, supplemental feeding can mitigate a lack of flowering plants nearby for foraging, and beekeepers can manage pests such as Varroa mites with cultural, mechanical and chemical control practices.” Scientists developed protocols to test different beekeeping management systems through participatory science. Thirty beekeepers were invited to work with scientists using protocols on experimental design, applying three different management approaches: i) conventional chemical; ii) organic; and iii) management without inputs. “We wanted to replicate what beekeepers were doing in their […]

Today, Beyond Pesticides released a special issue, Transformative Change: Informed by Science, Policy, and Action of its journal, Pesticides and You, with a compendium of “shocking scientific findings that compel us to act in our communities, states, and as a nation and world community.” The 168-page issue documents the last year of scientific, peer-reviewed articles, policy deficiencies, and action for change that intersect not only with petrochemical pesticides and fertilizers, but with existential health crises, biodiversity collapse, and the climate emergency.

(Beyond Pesticides, April 24, 2023) It is well-known that trees and other plants help fight climate change by sequestering carbon in their wood and roots—especially when they are allowed to grow continuously. However, plants help in other ways as well.  Plants—especially trees—also moderate the climate through their participation in the water cycle. And when the weather is hot and dry, they hold the soil, preventing dust bowl conditions. In the 1930’s, the U.S. Forest Service, Civilian Conservation Corps, and the Works Progress Administration, together with local farmers, planted more than 220 million trees, developing 18,000 miles of windbreaks on the Great Plains. Unfortunately, those windbreaks are now endangered by the same economic impetus that helped create the Dust Bowl—making more room for economically valuable crops.  Tell your U.S. Representative and Senators to address climate change in the Farm Bill by incorporating a large-scale, national transition to certified organic agriculture and restoration and resilience strategies that prohibit the use of petrochemical pesticides and fertilizers. Tell Secretary of Agriculture Vilsack to implement the NOSB recommendation to remove incentives to convert native ecosystems to organic farms.    Organic farming helps resist climate change in several ways. Regenerative organic farming sequesters carbon in the soil. Organic […]

(Beyond Pesticides, April 21, 2023) Into the annals of “entropic methods of agricultural pest control” arrives recent research showing that pests are, unsurprisingly, developing resistance to a genetically engineered (GE) biopesticide used for more than 90% of U.S. corn, cotton, and soybeans. Bt (Bacillus thuringiensis) is a naturally occurring bacterium; the versions deployed in conventional agriculture are engineered into Plant Incorporated Protectants (PIPs) — GE ingredients “inserted” into seeds for multiple kinds of crop plants. These PIPs target multiple crop-destructive insect species, including (in larval form) the corn rootworm and cotton bollworm, in particular. Beyond Pesticides continues to warn that “controls,” whether synthetic chemical pesticides or GE “biological” agents (such as GE Bt) that target living things (e.g., pests and weeds) are not sustainable over time because — in addition to the harms they cause — the issue of resistance will ultimately thwart their efficacy. There are two basic categories of genetic engineering employed in conventional agriculture. One technology transfers genetic material into seed to make plants tolerant of specific herbicide compounds that will be applied after planting (for example, the infamous “Roundup Ready,” glyphosate-tolerant seeds and plants). The other comprises plant-incorporated protectants (PIPs), in which the genetic material introduced […]
