(Beyond Pesticides, September 13, 2023) A study published in Global Change Biology finds climate change increases beesâ sensitivity to pesticide exposure, impairing the pollinatorsâ ability to respond to light (Ultra-Violet [UV] stimuli), reducing floral syrup consumption, and lessening longevity (length of life) up to 70 percent. Notably, the reduction in floral syrup consumption indicates nutritional stress that further impacts bee species’ fecundity (productiveness), driving bee declines. Unless more is done to combat the climate crisis, the current global warming scenario increasing beesâ sensitivity to pesticide exposure will continue to threaten all pollinator health. The pervasiveness of pesticide exposure, combined with climate change, threatens global species biodiversity. As has been widely reported, pollinators (such as bees, monarch butterflies, and bats) are a bellwether for environmental stress as individuals and as colonies. Pesticides intensify pollinatorsâ vulnerability to health risks (such as pathogens and parasites), with pesticide-contaminated conditions limiting colony productivity, growth, and survival. The globe is currently going through the Holocene Extinction, Earthâs 6th mass extinction, with one million species of plants and animals at risk, including pollinators. Pollinator declines directly affect the environment, society, and the economy. Without pollinators, many agricultural and nonagricultural plant species will decline or cease to exist as U.S. pollinator declines, particularly […]

(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 agricultureâwhich leaves residues of the toxic chemical in foodâand 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 functionsâfrom 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 beesâ brain via oxidative stress. Acute, field-realistic sublethal exposure to tebuconazole decreased the brainâs 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 23, 2023) The use of pesticides on pets for fleas and ticks (parasiticides) has been traced to environmental contamination in a study that confirms earlier work both by the authors and internationally, according to researchers Rosemary Perkins, a veterinary surgeon, and David Goulson, PhD at the University of Sussex. The results are published in their recent study, âTo flea or not to flea: survey of UK companion animal ectoparasiticide usage and activities affecting pathways to the environment,â which concludes that, â[T]he potential cumulative impact of parasiticide emissions [into the environment] from many millions of pets treated multiple times each year is of serious concern.â The UK provides an opportunity to pinpoint water contamination from pet use for ectoparasites (e.g., fleas and ticks) of hazardous pesticides since, unlike in the U.S., the country has banned outdoor use of those chemicals commonly detectedâthe insecticides fipronil and imidacloprid (the same neonicotinoid bug killer tied to devastating losses of bees and other organisms). These findings confirm the historical peer reviewed scientific literature and defy the assumption of regulators that home or veterinary use of pesticides do not reach levels of concern for environmental contamination, either through exposure from down-the-drain (DTD) contamination […]

(Beyond Pesticides, August 16, 2023) A study published in Environmental Science and Pollution Research further supports the indication that exposure to organophosphate insecticides (OPs) increases the risk of asthma among the U.S. general population. According to the Asthma and Allergy Foundation of America, âThe burden of asthma in the United States falls disproportionately on people with low-income, senior adults, and Black, Hispanic and American Indian/Alaska Native people,â making these groups more susceptible to developing this chronic lung disease upon OP exposure.  Organophosphorus pesticides have a wide range of biological usesâfrom insecticides to flame retardantsâthat make these chemicals ubiquitous, significantly contributing to ecosystem contamination. Furthermore, while organophosphates have less bioaccumulation potential, residues are consistently present in human and animal blood, urine, tissues, and milk. Although research demonstrates that OPs are highly toxic, there remains an inadequate understanding of how OP exposure impacts body systems like the repository system. The respiratory system is essential to human survival, regulating gas exchange (oxygen-carbon dioxide) in the body to balance acid and base tissue cells for normal function. However, damage to the respiratory system can cause several issuesâfrom asthma and bronchitis to oxidative stress that triggers the development of extra-respiratory manifestations like rheumatoid arthritis and cardiovascular disease. Therefore, the rise in respiratory illnesses and organophosphate […]

(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 studyâs 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 pesticidesâwhose uses are more commonly concentrated in homesâ 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, âPrevious research has highlighted the potential harm of pesticides on kidney function, particularly in outdoor uses. Our findings raise […]

(Beyond Pesticides, August 2, 2023) A study published in Pest Management Science finds resistance to insecticides like pyrethroids are challenging attempts to control the mosquito Aedes aegypti (Ae. aegypti), the primary transmitter (vector) of dengue fever. While this study takes place in Bangladesh, resistance to biocidesâwhether to antibiotics, antimicrobials, or pesticidesâis growing globally. Prevention of disease outbreaks is threatened by reliance on chemical biocides to which pathogens and their vectors develop resistance. In fact, resistance is predicted by elementary population genetics, and the speed of its evolution is directly related to the toxicityâthat is, the strength of selection pressureâand inversely related to the generation length of the organism. (See PAY articles here and here, a PBS article here.) Insecticide resistance has been an issue since the introduction of DDT (dichlorodiphenyltrichloroethane) in the 1940s. Although most countries currently ban DDT use, the compound is not the only chemical pesticide promoting pest resistance. Several current-use insecticides pose the same threat. Areawide, indiscriminate spraying of insecticides is causing resistance to develop among many pests. Mosquitoes have become increasingly resistant to synthetic pyrethroids, in addition to other classes of insecticides, such as carbamates and organophosphates. Thus, this study demonstrates the need for sustainable and practical strategies […]

(Beyond Pesticides, July 21, 2023) A comprehensive and scathing report, âNeonicotinoid insecticides: Failing to come to grips with a predictable environmental disaster,â issued by American Bird Conservancy (ABC)in June, lays out the dire consequences of neonicotinoid (neonic) pesticidesâ continued use. The report is an update of an earlier review from 2013, which warned of the risks to birds, stating starkly: âA single corn kernel coated with a neonicotinoid can kill a songbird. Even a tiny grain of wheat or canola treated with the oldest neonicotinoid, imidacloprid, can poison a bird. As little as 1/10th of a corn seed per day during egg-laying season is all that is needed to affect reproduction with any of the neonicotinoids registered to date.â The story of neonic harm is one that has been repeated for generations with different pesticides. Pesticide manufacturers claim every new generation of their products is safer and more environmentally benign than the previous one. This is seldom true. There is ample evidence that pesticides pose threats to nearly every class of organism on Earth, from earthworms to elephants. The neonicotinoids, introduced in the early 1990s, have been marketed as safe for vertebrates, non-bioaccumulative, and, because of their flexible application methods […]

(Beyond Pesticides, July 13, 2023) A study published in Environmental Science and Pollution Research finds exposure to p-Dichlorobenzene (p-DCB), a chlorophenol compound with uses as an insecticide, disinfectant, repellent, fumigant, fungicide, and deodorizer, can increase the risk of common endocrine (hormone)-mediated reproductive cancers (i.e., breast, uterine, and ovarian) in women. P-DCB or paradichlorobenzene has carcinogenic (cancer-causing) properties and the chemical has been banned in the European Union (EU) since 2005 for air fresheners and 2008 for mothballs. Being a chlorinated aromatic hydrocarbon (with benzene) compound (chlorobenzene), in addition to its cancer-causing properties, p-DCB can cause acute illnesses like headaches, numbness, sleepiness, nausea and vomiting and chronic effects like nervous system disorders leading to depression, and impact on the brain, birth outcomes, reproductive system, liver, and kidneys. Pesticides have a long history associated with endocrine-disrupting properties that induce various molecular changes, prompting disease development. Adding to the science, a similar review published in Environmental Exposure, Biomonitoring, and Exposure Assessment highlights how specific estrogen-mimicking pesticides increase the risk of disease, particularly hormone-related cancers among women (e.g., breast, ovarian, and endometrial cancer) and men (i.e., testicular, prostate cancer).PDCB, also known as para-dichlorobenzene, contains the carcinogen benzene and is chlorine-based (a chlorinated aromatic hydrocarbon compound), which in December 2019 […]

(Beyond Pesticides, July 12, 2023) A study by University of Delaware entomologist Thabu Mugala and colleagues finds that modifications to their farming methods can reduce slug damage when those changes also encourage natural slug predators, allowing farmers to avoid the endless cycle of pesticide dependency, pest resistance, genetically engineered crops, and synthetic fertilizers. With insects as the target for tens of millions of pounds of agricultural use, growers of the highest-production crops in the U.S., corn and soybeans, continue to find slugs to be a serious problem. Corn and soybean growers who have adopted no-till or conservation tillage and cover crops often think these practices worsen the problem by increasing moisture and decaying plant material in fields, which slugs love. But the cause-and-effect picture is more nuanced and requires strategies that nurture ecological balance. Slugs are the most damaging non-arthropod pest in no-till corn production in the U.S., and truly effective chemical deterrents do not exist at agricultural scale, as Beyond Pesticides noted here, although biological methods may be on the horizon, such as a parasitic nematode already used in Europe that shows promise. The most voracious natural slug hunters are ground beetles, but harvestmen (daddy longlegs), and wolf spiders […]

(Beyond Pesticides, July 6, 2023) A study published in Environmental Health Perspectives finds concentrations of organophosphate (OP) metabolites in urine during the prenatal phase have links to adolescent/young adult externalizing (e.g., hyperactivity, aggression, attention problems) and internalizing (e.g., depression) behavior problems. Thus, prenatal exposure to OP pesticides can permanently affect behavioral health as children mature into adulthood. This study adds to the growing body of research reinforcing the adverse effects of organophosphate (OP) exposure on cognitive health and neurological development, especially for infants and children. Prenatal development 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 research links to pesticide exposure and neurological and cognitive development, studies like this can help government and health officials identify how pesticidesâ impact on the brain elevates health concerns. Researchers gathered two urine samples from mothers during pregnancy (at weeks 13 and 26) and five urine samples from offspring from the ages of six months to five years old to measure urinary dialkylphosphates (DAPs) (nonspecific OP metabolites). Subsequently, the study also assesses reports of […]

(Beyond Pesticides, June 27, 2023) Pesticides interfere with biological processes. This is their purpose. Unfortunately, they nearly always have unintended consequences, many of which have been ignored by their manufacturers. A new review article by Irish and Dutch researchers in the ISME Journal adds to the emerging scientific literature examining how pesticides affect the relationship between the human gut and the human brain (the âgut-brain axisâ). Often called the âsecond brainâ because it houses nerve cells and produces neurotransmitters, the gut-brain axis may be the most important locus where microbes and pesticides meet. The human gut plays host to a variety of microorganisms, ranging from bacteria and archaea to fungi, viruses and yeasts.[1] In a healthy person these microbes remain in balance and often cooperate both with each other and with human cells. The gut and the brain are deeply integrated through the vagus nerve and the neuroendocrine system. The vagus nerve is a treelike bundle of fibers extending from the lower part of the brain to nearly every body organ, but particularly the heart, lungs and digestive tract. The neuroendocrine system comprises specialized cells inhabiting nearly all the organs of the body that respond to signals from the brain […]

(Beyond Pesticides, June 22, 2023) Since the early twentieth century, âmigratoryâ beekeepers have provided a critical service to U.S. agriculture by moving their hives seasonally to pollinate a variety of crops. Annually, commercial beekeeping adds between $15 and $20 billion in economic value to agriculture, which is a major industry in the United States, with 21.1 million full- and part-time jobs related to the agricultural and food sectorsâ10.5 percent of total U.S. employment. Before insects and pollinators like bees evolved to pollinate, pollination occurred through the wind, scattering the pollen from the plants and landing on other flowers that could reproduce. However, commercial pollination services contribute to increased yields. Without commercial pollination, food prices would rise, the farm sector would suffer globally, and the security and variety of the food supply would diminish. With the wild insect pollinator populations already in serious decline, commercial, migratory beekeeping is more than ever a vital piece of the agricultural economy. With pollinator decline, as an integral part of worldwide biodiversity collapse and the âinsect apocalypse,â commercial beekeepers face collapse as well. The United Nations states that 80 percent of the 115 top global food crops depend on insect pollination, with one-third of all U.S. crops depending on pollinators, according to the U.S. […]

(Beyond Pesticides, June 9, 2023) Glyphosate, usually marketed as the herbicide Roundup, has long been the poster child for shoddy regulation by both the U.S. Environmental Protection Agency (EPA) and the European Food Safety Authority (EFSA). In a study published June 1, 2023 in Environmental Health by Axel Mie and Christina RudĂŠn, PhD, of Stockholm University and the Centre for Organic Food and Farming in Uppsala, the authors followed up on earlier work that documented deficiencies in information provided to European Union (EU) regulators by manufacturers. They identified nine studies on developmental neurotoxicity (DNT) that had been submitted to the U.S. Environmental Protection Agency (EPA) but were not disclosed to EU authorities. According to the research, seven of these studies would have âactual or potential regulatory impact.â According to the authors: âOf the nine undisclosed DNT studies, three were sponsored by Bayer and performed in their own laboratory. Three studies were sponsored by Syngenta and performed in their Central Toxicology Laboratory. One study each was sponsored by Nissan Chemicals and Ishihara Sangyo Kaisha (ISK), and these were performed at Huntingdon Life Sciences. For the remaining study, the sponsor and laboratory are unknown to us.â This study is a new example […]

(Beyond Pesticides, June 7, 2023) A systematic review of scientific literature published in Environmental Research on the development of mood disorders among pesticide applicators (farmers, landscapers, etc.) finds an increased risk of depression symptoms over the last decade. The evidence in the review highlights the presence of pesticide-specific biomarkers and biomarkers of depression that determine the positive association between pesticide exposure and the development of depressive symptoms. With more high-quality longitudinal studies to control sociocultural variables, researchers can directly pinpoint risks of developing depression, especially among agricultural workers and landscapers who use pesticides. Research on pesticide-induced diseases commonly investigates pesticide exposure concerning the development of various physical illnesses. However, previous studies show that occupational (work-related) risks of developing depression are high in agriculture, where pesticide use is rampant. Acute exposure to chemicals, including organophosphate, organochlorine, triazine, and carbamate pesticides, tends to put farmers at greater risk of suicide than the general population. There is a lack of information connecting pesticide exposure to the subsequent psychological (psychiatric) effects on the general population. Additionally, household pesticide exposure varies from occupational exposure via exposure frequency, duration, intensity, and type.  According to the World Health Organization (WHO), depression affects 322 million people globally, with the number of diagnosed patients increasing by 18.4% from 2005 to […]

(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 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. âWe are not saying these mice have autism or that they have ADHD. That’s not the goal here,â said James Burkett, PhD, study coauthor and assistant professor of neuroscience in the UToledo College of Medicine. âWhat 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 âwell below the benchmark dose for regulatory guidance.â 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, April 21, 2023) Into the annals of âentropic methods of agricultural pest controlâ 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) â GE ingredients âinsertedâ 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 âcontrols,â whether synthetic chemical pesticides or GE âbiologicalâ agents (such as GE Bt) that target living things (e.g., pests and weeds) are not sustainable over time because â in addition to the harms they cause â 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 âRoundup Ready,â glyphosate-tolerant seeds and plants). The other comprises plant-incorporated protectants (PIPs), in which the genetic material introduced […]

(Beyond Pesticides, April 6, 2023) A study published in Global Change Biology adds to research demonstrating that climate change can exacerbate the adverse impacts of pesticide exposure on managed and wild bees. Temperature can alter the sublethal effect pesticides, particularly the neonicotinoid (neonic) imidacloprid and the sulfoximine sulfoxaflor, have on bumble bee behavior tied to fitness and pollination services. Both an increase and decrease in temperature can cause diverging thermal responses in bumble bee behavior. However, increasing temperature bares more severe behavior abnormalities than cooler temperatures. The pervasiveness of pesticide exposure combined with climate change threatens global species biodiversity. As has been widely reported, pollinators (such as bees, monarch butterflies, and bats) are a bellwether for environmental stress as individuals and as colonies. Pesticides intensify pollinatorsâ vulnerability to health risks (such as pathogens and parasites), with pesticide-contaminated conditions limiting colony productivity, growth, and survival. Now more than ever, people are changing their sentiment toward sustainability, with two-thirds of consumers stating the importance of limiting climate change impacts and 88 percent supporting greater pollution reduction. The globe is currently going through the Holocene Extinction, Earthâs 6th mass extinction, with one million species of plants and animals at risk. With the increasing rate of biodiversity loss, advocates say it is essential for […]

(Beyond Pesticides, March 7, 2023) Exposure to glyphosate (Roundup) and its breakdown products is associated with an increased risk of liver and metabolic disorders in children and young adults, according to research published in Environmental Health Perspectives earlier this month. While glyphosate has developed a well-deserved reputation as a carcinogen, research is finding that cancer is one of a myriad of chronic diseases associated with the notorious chemical. As this body of literature grows, growing awareness by the public is increasing pressure on the U.S. Environmental Protection Agency to cancel its allowed uses. Researchers began their investigation concerned about the rise of liver disorders and metabolic syndrome among young people. This trend has been pronounced among populations of color. The worrying increase has led many to consider synthetic chemical exposure as a contributing factor, as lack of diet and exercise is unlikely to account for the entirety of the increase. To better understand these impacts, researchers enrolled existing participants in the CHAMACOS (Center for the Health Assessment of Mothers and Children of Salinas) study, a long running cohort of mothers and their children born between the years 2000 and 2002 in the Salinas Valley of California. Enrolled participants consistent mostly […]

(Beyond Pesticides, February 15, 2023) Areas designated to protect insects fail to do so for over 75 percent of global species, according to a study, âThree-quarters of insect species are insufficiently represented by protected areas,â published in the online journal One Earth. Protected Areas (PAs) act as a safeguard for biodiversity. However, PAs in North America, Eastern Europe, Southeast Asia, and Australia do not meet the minimum coverage requirements to safeguard global insect species assessed in the study. PAs are discussed in the 2020 Nature article, âArea-based conservation in the twenty-first century,â in which the authors state that, in view of the global biodiversity crisis, national governments must do much more to increase protected areas with âcoverage across different elements of biodiversity (ecoregions, 12,056 threatened species, âKey Biodiversity Areasâ and wilderness areas) and ecosystem services (productive fisheries, and carbon services on land and seas).â The authors write, citing the UN Convention on Biological Diversity (to which the United States is not a signatory), âTo be more successful after 2020, area-based conservation must contribute more effectively to meeting global biodiversity goalsâranging from preventing extinctions to retaining the most-intact ecosystemsâand must better collaborate with the many Indigenous peoples, community groups and private initiatives […]
