(Beyond Pesticides, January 30, 2025) A research article in Biology Letters, published by The Royal Society, finds that the neonicotinoid insecticide imidacloprid disrupts survival and reproductive patterns in Bombus impatiens bumblebees. The study adds to the wide body of science highlighting how exposure to pesticides âcan result in immediate mortality or cause long-term detrimental effects on pollinators‘ health, lifespan and reproductive success,â the authors state. The researchers performed two experiments to assess the effects of various concentrations of imidacloprid, one of which focuses on bees during diapause, a period of dormancy. âWild bees, which provide the majority of pollination services worldwide, undergo an annual life cycle that includes a winter diapause, that can span over 75% of their life cycle and during which their metabolism, growth and development are halted,â the authors note. They continue: âThe time spent in diapause can have lasting effects on pollinator fitness and their ability to establish nests or colonies in the following spring. This period is especially critical for social bee colonies, which are founded by a single queen after diapause and play a vital role in large-scale pollination.â Exposure to pesticides during diapause can occur while bee species overwinter in contaminated soils. In […]

(Beyond Pesticides, January 24, 2025) Based on data collected from government sources and independent monitoring, a multidisciplinary team of researchers at the University of Connecticut finds that 46% of Connecticut waterway samples are contaminated with levels of the neonicotinoid insecticide, imidaclopridâone of the most widely used insecticides in the United States on lawn and golf courses. The authors relied on federal data from U.S. Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS), state-level data from Connecticut Department of Energy and Environmental Protection (CT-DEEP), and a small-scale data collection study by the Clean Rivers Project funded by the nonprofit Pollinator Pathway, Inc. In their report, Neonicotinoids in Connecticut Waters: Surface Water, Groundwater, and Threats to Aquatic Ecosystems, the researchers provide the most comprehensive view to date of neonicotinoid levels in Connecticut and offer critical recommendations for future testing within the state and nationally, given glaring data gaps. It is important to note that the authors acknowledged early in the report the “abandonmentâ of Integrated Pest Management in âthe use of neonicotinoids has coincided with and been implicated in the decline of many non-target species of insects, in particular pollinators such as bees () and monarch butterflies.â They point out that […]

(Beyond Pesticides, January 23, 2025) According to reporting by Bangor Daily News, âStarting in 2025, the Miâkmaq Nation, [Upland Grassroots], [University of Virginia], the Connecticut Agricultural Experiment Station and Central Aroostook Soil and Water Conservation District will use a four-year, $1.6 million EPA grant to continue hemp planting at [the former] Loring [Air Force Base] and testing potential ways to extract PFAS [per- and polyfluoroalkyl substances] from harvested hemp.â This grant will support an existing initiative led by members of the Miâkmaq Nation to remediate this contaminated Superfund-designated land purchased from the U.S. government in 2009 based on interviews of the Nationâs Vice Chief Richard Silliboy. Â PFAS, colloquially known as âforever chemicals,â persist in various petrochemical-based pesticides, chemicals, and other consumer products. Beyond Pesticides, in coordination with national coalitions and local communities, continues to act against the proliferation of PFAS and PFAS-contaminated products through grassroots organizing and litigation. The use and associated public and environmental exposure to PFAS as pesticide active ingredients in pesticide products and a wide range of consumer products (including containers holding pesticides targeting mosquitoes and sewage sludge fertilizers) represent a grave threat as a result of their use in homes, emergency rooms, health care facilities, […]

(Beyond Pesticides, January 16, 2025) In Ecotoxicology and Environmental Safety, researchers highlight a multitude of studies on endocrine disrupting chemicals (EDCs) and endocrine disrupting pesticides (EDPs) showing epigenetic effects from exposure. These EDCs imitate the action of endocrine hormones and lead to gene damage and multigenerational adverse effects to health. âThese chemicals can interfere with the normal functioning of target tissues by altering their response to hormonal signals, thereby affecting various physiological processes including reproduction, development, the nervous system, the immune system, and even the process of carcinogenesis [causing cancer],â according to the authors from Hebei Agricultural University and Chinese Academy of Agricultural Sciences. Â In causing epigenetic modifications, the authors describe that EDCs can create changes âat the nuclear and mitochondrial DNA (nDNA and mtDNA) or RNA levels, without changing the underlying DNA sequence. These alterations modify the structure or conformation of DNA, influencing gene expression and, consequently, cellular function.â They continue, âThe mechanisms of epigenetics include changes in DNA methylation, chromatin modifications and the involvement of certain noncoding RNAs.â In reviewing over 80 studies on EDCs, predominantly fluorinated compounds such as per- and polyfluoroalkyl substances (PFAS), the researchers provide a summary of linkages between pesticide exposure and the […]

(Beyond Pesticides, January 15, 2025) There is robust scientific literature that unpacks the adverse human health effects of pesticide exposure, however immunological impacts do not receive adequate attention in regulatory review processes, according to an in-depth literature review. In a piece published in Frontiers in Immunology (2024) critiquing recent peer-reviewed scientific studies, as well as unpublished research produced by the Institute of Biology and Experimental Medicine in partnership with the National Scientific and Technical Research Council in Argentina, researchers assess immune system effects of pesticide exposure, which creates the conditions for deadly health conditions including various forms of cancer. The focus of this study, according to the authors, is âto critically review fundamental aspects of toxicological studies conducted on PPPs [Plant Protection Products] to provide a clearer understanding of the risks associated with exposure to these compounds on human health.â PPPs are pesticide products that contain more than one active ingredient, and can include synergistic ingredients that supercharge them alongside inert ingredients that pesticide companies are not legally required to disclose under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), but are often manipulated biologically and chemically active. Most studies analyze the toxicological impacts of active ingredients in isolation rather […]

(Beyond Pesticides, January 9, 2025) In a Frontiers in Public Health review article, researchers report on the wide body of science connecting adverse effects to female reproductive system, such as infertility, with exposure to endocrine-disrupting chemicals (EDCs). The authors call these effects a significant concern for public health, as there has been growing evidence of EDCs with risk factors for decreased fertility.  Infertility âaffects a substantial proportion of the worldâs population with approximately one in six people affected,â the researchers note. They continue: âOver the last 70 years, global fertility has been constantly in decline due to behavioral and societal changes… [E]merging evidence has shown that infertility incidence is linked to exposure to environmental factors such as tobacco, alcohol, and a wide range of endocrine-disrupting chemicals (EDCs) including pesticides (chlorpyrifos, glyphosate, dichlorodiphenyltrichloroethane [DDT] and methoxychlor), phthalates, polychlorinated biphenyls (PCB), dioxins, and bisphenols.â In this review, over 100 studies are summarized to showcase the link between EDC exposure and reproductive effects in women, including infertility and related diseases such as endometriosis, premature ovarian insufficiency (POI), and endocrine axis dysregulation. The studies included investigating the âmechanisms by which EDCs cause ovarian aging, folliculogenesis, decrease of oocyte quality, ovulation disorders, development and receptivity […]

(Beyond Pesticides, January 3, 2025) Pesticides that are sprayed and become airborne significantly disrupt ecological balances and affect nontarget species that are crucial for maintaining biodiversity, according to an article in Environmental Pollution. In this review of studies throughout countries in North and South America, Europe, and Asia, among others, researchers from Germany, Norway, the United Kingdom, and Poland reinforce the science about pesticidesâ direct effect on species and the cascading effects of pesticide drift through various trophic levels within food webs that lead to overall devasting population effects. This study âaddresses the interconnectedness of these impacts and illustrates the complex threats that pesticide drift poses to biodiversity across multiple ecosystems,â the researchers state. They continue: âImpacts include reduced reproductive rates, changes in growth, development, and/or behavior, modification of diversity or community organization, disruption of food webs, and declines of important species. Pesticides disrupt the delicate balance between species that define a functioning ecosystem. Impacts can be local, transnational, or even continental.â Pesticide drift threatens beneficial species and subsequently the entire agricultural system. The process of pesticide drift, âin which up to 25% of applied pesticides are carried by air currents, can transport chemicals over hundreds or even thousands of […]

(Beyond Pesticides, January 2, 2025) Adding to the body of scientific literature on the fast escalating antibiotic resistance crisis is a study published by Chinese scientists in Environmental Science & Technology, which shows that antibiotic resistance genes (ARGs) in soils move up through trophic levels via predation. Gut microbiomes of soil fauna have been found to be reservoirs of ARGs. How this process operates in soils is vital, because what happens in soil microbes does not stay there. If bacteria altered in soils move up trophic levels, ARGs may strengthen the multicellular agricultural pests the industry is trying to killâinsects, fungi, plantsânot to mention bringing their libraries of resistant genes into the microbiomes of vertebrates, including humans. Antibiotic resistance is a natural phenomenon, but human activity has greatly increased its presence in ecosystems the world over, including in one of the ecological niches of greatest concern to the future of food and human health: soils. Soils are complexes of mineral and organic substrates populated by billions of microorganisms and tiny animals. They are rapidly being degraded by conventional agriculture, forestry, and land management practices generallyâmore than a third of the worldâs agricultural land has already been severely damaged by pesticides, […]

(Beyond Pesticides, December 19, 2024) As The New York Times reported last month, the government in South Africa declared a national emergencyâ23 children died and nearly 900 people were sickened from pesticide poisoning in Johannesburgâs Soweto township. The illnesses and fatalities have been traced to small amounts of highly neurotoxic pesticides, including the insecticides terbufos and aldicarb, found in local food items. These chemicals, described by South African President Cyril Ramaphosa as âstreet pesticides,â are being increasingly used (legally and illegally) for pest infestations in the townships and informal settlements of South Africaâs poorest communities, where poverty and inadequate waste collection exacerbates the pest management challenges. Without formal electricity, running water, or municipal garbage collection, many residents rely on highly toxic pesticides for pest infestations in their homes and makeshift markets, resulting in food inadvertently being contaminated with pesticides. The announcement highlights the dangers of allowing these highly toxic agricultural chemicals to be used in farming, with tragic consequences for vulnerable communities when they are diverted for use in urban settings. This tragic situation also draws attention to the elevated threat that pesticides pose when stringent enforcement mechanisms are not in place to ensure compliance with pesticide restrictions, even with […]

(Beyond Pesticides, December 18, 2024) A bombshell investigation conducted by Canadaâs National Observer finds that Bayer, which acquired the Monsanto chemical company in 2018, colluded with environmental and public health regulators in Canada to obstruct a proposed neonicotinoid insecticide ban originally introduced in 2018. Advocates were stunned back in 2021 when Canadaâs Pest Management Regulatory Agency (PMRA)âthe Canadian counterpart to the U.S. Environmental Protection Agency (EPA)âreversed its decision to phase out imidacloprid, clothianidin, and thiamethoxam by 2023. The weaponization of scientific institutions and regulatory processes is commonplace in the U.S. context, with U.S. Right to Know publishing a report earlier this year on the corrupting impact of pesticide manufacturers at the Entomological Society of America 2023 annual meeting. (See Daily News here.) There are numerous Office of Inspector General (OIG) reports signaling EPA corruption and failures, including persisting industry influence in the cancer risk assessment process, inadequate leadership in addressing community harms of a former creosote-treated wood preservative plant turned Superfund site in Pensacola, Florida, and failure to protect the public from endocrine-disrupting chemicals, to name several examples. In a recent press release, the David Suzuki Foundation, alongside numerous medical, legal, and civil society organizations, is calling on Health Canada […]

(Beyond Pesticides, December 17, 2024) A systematic review of studies on pesticides as endocrine-disrupting chemicals (EDCs) on body weight, published in Biomedicines, evaluates 36 clinical and preclinical studies and links their agricultural use to obesity. The authors, with the lead researchers from the School of Medicine and Health Sciences at Catholic University of Valencia San Vincente, Valencia, Spain, assess studies on a range of pesticides, including organophosphates, pyrethroids, neonicotinoids, and others. In addition to concluding that the EDCs promote obesity, they report that the chemicals cause âother anthropometric changes by altering lipid and glucose metabolism, modifying genes, or altering hormone levels such as leptin.â Endocrine disruption and obesity are public health concerns, and there is a wide body of science linking pesticide exposure to these effects (see more here). âObesity is considered to be a worldwide pandemic that leads to an increase in medical costs and thus becomes a public health problem,â the researchers share. They continue, â[Obesity] is also associated with the increased production of environmental chemicals, also called environmental obesogens, used mainly in agriculture, as disease vector control, helping to prevent harmful effects caused by fungi, bacteria, or even pests, using pesticides, insecticides, and herbicides, or endocrine disruptors […]

(Beyond Pesticides, December 16, 2024) The fact that three-quarters of all U.S. fruits and nuts and one-third of all U.S. vegetables are grown in California means that all U.S. food eaters have a stake in how food is grown there. California is proposing the continued use of the fumigant 1,3-dichloropropene (1,3-D, also known as Telone), which can cause deadly effects to farmworkers and endocrine disrupting effects to communities of people exposed through nontarget chemical drift from farmland. So, it is with deep concern that Beyond Pesticides is urging the state of California, where the chemical is undergoing review, to ban the toxicant. Endocrine disruption, an adverse effect for which the U.S. Environmental Protection Agency (EPA) has never completed a pesticide testing protocol, adversely affects the functioning of glands and hormones and is linked to major life-threatening diseases in most organ systems in the bodyâcontributing to attention deficit hyperactivity disorder (ADHD), Parkinsonâs, Alzheimerâs, diabetes, cardiovascular disease, obesity, early puberty, infertility and other reproductive disorders, and childhood and adult cancers. In a recently released draft regulation, the California Department of Pesticide Regulation (CDPR) will allow highly elevated exposure to 1,3-D, ignoring the scientific literature and advice of the stateâs own toxicologists at […]

(Beyond Pesticides, December 13, 2024) In October, the U.S. Environmental Protection Agency (EPA) approved the registration applications of BASF Corporation and Mitsui Chemicals Crop & Life Solutions, Inc. for the use of different formulations of the L-isomer of glufosinate (also known as âL-glufosinateâ and âglufosinate-Pâ) as new active herbicidal ingredients. This decision marks one of the first times that EPA has employed its new Herbicide  Strategy Framework to determine the level of mitigation necessary to protect listed species and critical habitat under the Endangered Species Act (ESA). Glufosinate is an organophosphate, with known neurotoxic, reproductive/developmental effects, toxic to aquatic life, and mobile in soils (see Beyond Pesticides Gateway). Scientists have found that formulated glufosinate is generally more toxic to aquatic and terrestrial animals than the technical grade active ingredient. Manufacturers are introducing newer glufosinate products as alternatives for glyphosate-based herbicides, like Bayer/Monsantoâs âRoundupâ and dicamba. The Center for Biological Diversity notes in comments submitted to EPA on this decision, âL-glufosinate has the potential to be used on tens of millions acres of land every year given the crops EPA has proposed to register it on. The scale of potential use is far above most new active ingredients.â This first significant application […]

(Beyond Pesticides, December 12, 2024) A literature review of 161 articles in Discover Toxicology finds that pesticides with different mechanisms of action cause memory and learning impairments. These effects are noted in nontarget species including humans. Pesticide â[e]xposure during development, as well as chronic environmental and occupational exposure, can contribute to decreased cognitive performance,â the researchers say. With a focus on organophosphate pesticides, synthetic pyrethroids, and neonicotinoid insecticides, the authors highlight neurological impacts. Both learning and memory are crucial for the survival of many species. “Considering the importance of learning and memory for human and non-human animal behavior and the growing association between pesticide exposure and cognitive impairment, the aim of this review was to describe the studies showing the impact of pesticide exposure on memory and learning abilities in nontarget species, providing evidence of the impact of pesticides in central nervous system function,â the researchers state. The 161 articles included in the review were identified through database searches in PubMed/Medline and Scielo. The authors note, âInclusion criteria for article selection included all articles published in English between 2015 and 2024 containing original studies in animals or humans with single or multiple pesticides exposure.â The articles consist of 132 preclinical […]

(Beyond Pesticides, December 10, 2024) Scientists from the Engineering Research Center of Protection and Utilization of Plant Resources at Shenyang Agricultural University in China reveal adverse effects of imidacloprid on soil communities in a study published in Pesticide Biochemistry and Physiology. The researchers highlight risks to nematodes from imidacloprid exposure in maize soil, as well as potential resistance mechanisms that impact not only nematode populations but also overall soil health. Maize, or corn, a productive crop grown worldwide, is a source of food and biofuel. In assessing the soil and species in maize fields after exposure to imidacloprid at various concentrations, the study researchers assess the impact of neonicotinoid insecticides on nontarget organisms and the health of soil communities. The assessment includes an evaluation of nematodesâ survival, growth, reproduction, and chemotaxis/locomotion behavior. With a statistical analysis of lipid and lipofuscin accumulation, acetylcholinesterase (an enzyme necessary for neurotransmission) activity, and gene expression levels, the study results show that imidacloprid induces: significantly reduced abundance and diversity of nematode species. negative effects on body length, reproduction, locomotion, lipid accumulation, lipofuscin accumulation, and acetylcholinesterase activity in Caenorhabditis elegans ( elegans). the upregulation of gpa-1, cyp-35a2, fat-2, fat-6, hsp-16.41, and hsp-16.2, along with the downregulation […]

(Beyond Pesticides, December 9, 2024) In recognition of the explosion of a chemical plant in Bhopal, India 40 years ago that was responsible for the death of 20,000 people, U.S. Representative Pramila Jayapal introduced H.Res. 1604, âRecognizing the 40th year since the 1984 Bhopal chemical disaster and helping to ensure that no other community suffers another chemical disaster, by supporting the designation of December 3 as National Chemical Disaster Awareness Dayâ and calling for support of survivors of the disaster and promoting public understanding of the dangers of chemical disasters. The Union Carbide Corporation (UCC) plant explosion released a cloud of highly toxic methyl isocyanate (MIC) gas in the middle of the night, killing thousands of people immediatelyâestimates range from 1,754 to 10,000âand up to 20,000 subsequently. Estimates of the number suffering permanent disabilities or chronic disease range up to 95% of the affected population of 531,881. MIC is a precursor used in the manufacture of carbamate insecticides, including aldicarb, carbofuran, and carbaryl. In spite of this history and the many adverse effects of these extremely toxic pesticides and their precursors, EPA continues to register pesticides without considering cradle-to-grave risks. >> Tell EPA that harm done in the manufacture, transportation, […]

(Beyond Pesticides, December 6, 2024) On December 2, the U.S. Environmental Protection Agency (EPA) announced yet another milestone in the convoluted life span of the insecticide chlorpyrifos. Under the deceptive headline âEPA Proposes Rule to Revoke Most Food Uses of the Insecticide Chlorpyrifos,â EPA stated that it is improving environmental protection by revoking all usages of chlorpyrifos except for 11 food and feed crops. The proposal was deemed âunconscionableâ by Beyond Pesticides executive director Jay Feldman in an article in The New Lede. EPA claims this plan would reduce annual chlorpyrifos application by 70% compared to âhistorical usage.â Chlorpyrifos is a known neurological and reproductive toxicant. EPA has been cutting back on approved uses for years but is far behind other environmental authoritiesâthe European Food Safety Authority and Thailand have banned it altogether, and California has banned its agricultural use. The trouble with EPAâs latest attempt is that it does nothing to clarify and rationalize EPAâs process, and it will not protect the public, because those 11 remaining products are among the most extensively grown and used in the world: soybeans, sugar beets, cotton, wheat, apples, citrus fruits, strawberries, alfalfa, cherries, peaches, and asparagus. Chlorpyrifos is an organophosphate chemical. These […]

(Beyond Pesticides, December 5, 2024) A novel, comprehensive study published in Science reviews a library of 1,024 different chemicals (herbicides, insecticides, fungicides, and plant inhibitors) finding that, even at âsublethalâ exposure levels, 57% of tested chemicals impact the behavioral and physiological health of house fly larvae. Mosquito and butterfly populations are also susceptible to long-term adverse effects at sublethal levels. Environmental and public health advocates continue to raise concerns about adverse effects resulting from the failure of the U.S. Environmental Protection Agency (EPA) to consider cumulative exposure (resulting in aggregate and synergistic effects) across different mechanisms of toxicity and different classes of pesticides, including at exposure levels below allowable levels set by the agency. In the context of the regulatory gaps and pesticide industry influence at EPA (See Daily News here), advocates stress the importance of transitioning land and agricultural practices to organic principles. Methodology and Results Background, Goals, Primary Takeaways This research was led by an international team of experts from various universities and institutes, including European Molecular Biology Laboratory (EMBL), Institut Pasteur, and Heidelberg University (Center for Infectious Diseases, Parasitology Department).

(Beyond Pesticides, December 3, 2024) In an article in Science, Sabrina Rondeau, PhD reviews her research from 2022-2024 showcasing species of ground-nesting bees, often found in crop fields, that are highly vulnerable to soil pesticide residues and subsequently suffer population declines. Dr. Rondeau, a postdoctoral fellow in the Department of Biology at the University of Ottawa, points to regulatory deficiencies, specifically in environmental risk assessments (ERAs), and the detrimental effects of pesticides on pollinators that threaten food security and biodiversity. âModern intensive agriculture faces a critical paradox: The very pesticides designed to protect our crops endanger essential pollinators that sustain their productivity,â Dr. Rondeau says in the article. Her research (see here, here, here, here, here, and here) identifies important gaps overlooked in current assessments and regulations for bee species, including the common eastern bumble bee (Bombus impatiens) and the hoary squash bee (Xenoglossa pruinosa). Bumble bee queens in temperate climates hibernate for 6-9 months in the soil, while the hoary squash bee is a solitary ground-nesting species. Reference additional Daily News coverage on ground-nesting bees here and here. ââOur findings show that over 70% of wild bee species, which are crucial for pollinating our food crops, face significant risks […]

(Beyond Pesticides, November 26, 2024) A study in Environment International finds that young children who exhibit higher levels of pesticide metabolites in their urine show more pronounced neurobehavioral problems at the age of ten. Researchers in China document how exposure during early childhood, especially during the sensitive window before the age of two, is linked to hyperactivity/inattention problems such as attention deficit hyperactivity disorder (ADHD). While adding to the body of science connecting pesticide exposure to learning and developmental disorders, this study offers a “novel perspective on characterizing the fluctuation in repeated measurements of multiple environmental chemicals and identifying the potential critical windows,â the authors share. (See previous Daily News coverage here, here, and here.) The researchers analyze data from questionnaires and urine samples through the ongoing Sheyang Mini Birth Cohort Study (SMBCS), which is a long-term prospective cohort study that associates environmental chemical exposure during pregnancy and childhood to negative health effects. This data addresses combined pesticide exposures in young children with neurobehavior analyses at the age of ten to determine any correlation. Within the SMBCS, a total of 1303 pregnant women are enrolled. When the children reached ages one, two, three, six, seven, eight, nine, and ten years […]

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

(Beyond Pesticides, November 15, 2024) There are many pie-in-the-sky ideas to address the climate crisis while allowing business as usual in the extractive and industrial systems that are causing the crisis. Prominent among them are geoengineering to block sunlight and building industrial plants to prevent carbon dioxide (CO2) from reaching the atmosphere, known as carbon capture and sequestration (CCS). Like geoengineering, CCS is a âsolution for the future that always will be.â It has garnered decades of hype, research, and government funding of prototype projects without doing much of anything to remove carbon and keep it out of the atmosphere. The Biden administrationâs Inflation Reduction Act (IRA) contains numerous revenue streams aimed at coping with the climate crisis, including CCS. But it is a mixed bag of good and bad ideas. Beyond Pesticides analyzed the IRA in 2022, lauding the actâs âprovision of unprecedented sums to address the existential threats we face related to climate, biodiversity, and health.â These include about $21 billion for âclimate smartâ agriculture and programs to reduce petrochemically dependent farming. But the analysis also details the many provisions for infeasible and counterproductive projects. Rather than complex and expensive technological projects, the best practitioners of CCS are […]

(Beyond Pesticides, November 13, 2024) A study in Chemosphere, conducted by researchers from the Institute of Biochemistry and Molecular Biology in Germany, reveals the varied lethal and sublethal effects of different glyphosate mixtures through tests on the South African clawed frog, Xenopus laevis (X. laevis). After exposing embryos to four glyphosate formulations, mortality, morphological defects, altered heartbeat rate, and impaired heart-specific gene expression are observed. Glyphosate, an herbicide and popular weed killer in many RoundupÂŽ products, is one of the most commonly detected pesticides in waterbodies worldwide, threatening aquatic organisms and overall biodiversity. This study investigates the effects of Glyphosat TF, Durano TF, Helosate 450 TF, and Kyleo, four formulations containing glyphosate, as compared to the effects of pure glyphosate on embryonic development in amphibians. The formulations consist of varying concentrations of the active ingredient glyphosate, as well as other active and inert ingredients.
