(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 “gut-brain axis”). Often called the “second brain” 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 15, 2023) The Supreme Court’s recent ruling in Sackett v. Environmental Protection Agency (EPA) on the Clean Water Act’s jurisdiction dramatically limits the EPA’s ability to protect critical wetland ecosystems. On May 25, in a 5-4 majority decision, the Supreme Court ruled that EPA has authority to protect only “wetlands with a continuous surface connection to bodies that are ‘waters of the United States’ in their own right.” Wetlands must appear “indistinguishable” from larger waterways at a surface-level perspective. Wetlands next to a large waterway are no longer protected if they are separated by a manmade or terrestrial barrier. Water flows underground from upstream to downstream sources and exits the confines of its customary boundaries during periods of flooding, so to declare waterways distinct based merely on a surface-level perspective defies scientific understanding of ecosystem health.  Critical Nature of Wetland Ecology  The conservation of wetland ecology is critical to the health of our environment. The United States Geological Survey (USGS) states, “Wetlands are among the most productive habitats on earth” given their role in flood resilience, improvement in water quality, and coastal erosion control. Wetlands are essential nursery grounds for many species of fish and oases for […]

(Beyond Pesticides, June 14, 2023) A study published in Scientific Reports finds a link between pesticide exposure and recurrent pregnancy loss (RPL) through oxidative stress and apoptosis (cell death) in the placenta. Recurrent pregnancy loss (RPL) is the loss of three or more successive pregnancies before 24 weeks of gestation (pregnancy) and signifies an underlying reproductive health issue. The study highlights that pesticides’ endocrine-disrupting (ED) properties can have varying adverse impacts on biological processes, including immunology, metabolism, and reproduction. Pregnant women experience frequent exposure to environmental pollutants that pose serious health risks to both mother and newborn. Many known pollutants (e.g., heavy metals, polychlorinated biphenyl, and pesticides) are chemicals with ED properties that can move from the mother to the developing fetus at higher exposure rates. Additionally, pregnant women are experiencing exposure to an increasing number of dangerous industrial chemicals. With a range of scientific data highlighting chemical exposures during pregnancy as a critical window of vulnerability, public awareness of these threats is growing. The study notes, “They are associated with an increasing placental OS [oxidative stress] and placental apoptosis. Specific measures should be taken to decrease maternal exposure to these pollutants’ sources, especially in underdeveloped and developing countries.” For RPL, the research investigated pesticide components in blood plasma, […]

(Beyond Pesticides, June 13, 2023) The specific compounds that comprise one’s scent influence how attractive one is to mosquitoes finds research published in the journal Current Biology by scientists at Johns Hopkins University. Although the findings focus solely on a species of malaria mosquito primarily distributed throughout Sub-Saharan Africa, the results could provide insight into broader concerns over mosquito disease transmission and public health. As it currently stands, personal protective measures and the use of least-toxic repellents are the best methods to address most mosquito problems in the United States. Scientists utilized a mixture and semi-field trials to understand first how mosquitoes became attracted to human hosts. For the field trial, a large facility the size of a college lecture hall was utilized to mimic the sort of open space mosquitoes have available to them in the wild. Eight landing boards were placed in a ring and either heated to human temperature, “baited” with carbon dioxide, or both. Researchers then released 200 mated female mosquitoes that had been starved of food. Scientists tracked the mosquitoes through infrared cameras to determine their trajectory. Only when both heat and carbon dioxide were present did scientists witness high levels of landings on the […]

(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 Rudén, 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 “actual or potential regulatory impact.” According to the authors: “Of 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.” This study is a new example […]

(Beyond Pesticides, June 8, 2023) A study published in Nature Communications finds that climate-induced thawing of permafrost (a ground that remains completely frozen for two or more years) threatens approximately 4,500 industrial sites in regions of the Arctic. These thousands of industrial sites used to store hazardous substances have an estimated 13,000 to 20,000 contaminated locations. Not only do these regions pose a grave ecological risk to the Arctic, but they threaten the entire globe. Many studies warn that thawing permafrost in the Arctic region can prompt the reemergence of greenhouse gases (e.g., methane and carbon dioxide), microbes, and hazardous chemicals (e.g., banned pesticides like DDT, heavy metals, etc.). Gases, microbes, and chemicals can drift near the poles, becoming entrapped in ice under the accumulating snowfall. As the global climate continues to rise and the climate crisis worsens, studies like this heed warning of potential adverse effects as ice encapsulating these toxic chemicals melt. Upon melting, some chemicals can volatilize back into the atmosphere, releasing toxicants into the air and aquatic systems, with the ensuing consequences. Microbes frozen for thousands to millions of years can also emerge from thawing permafrost, with unknown implications on human, animal, and ecosystem health. The melting permafrost is already […]

(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 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 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 16, 2023) U.S. Fish and Wildlife Service (USFWS) is set to be sued for its failure to implement strong protections for imperiled manatee populations. Earlier this month, the Harvard Animal Law and Policy Clinic, Center for Biological Diversity, Miami Waterkeeper, and engineer Frank González Garcia sent USFWS a notice of intent to sue after USFWS failed to respond to a petition sent by the groups last fall. “It has been months of agony and unjustified time lost for manatees in Puerto Rico,” said Mr. Garcia, an engineer who is concerned with the loss of natural resources. “Recent fatal accidents and unprecedented toxic water discharges aggravate the already precarious living and survival conditions of this beloved species,” Mr. Garcia said. Recent reporting has captured a dismal situation for manatee populations. The species is under threat from a range of anthropogenic impacts, from boat strikes to harmful herbicide contamination, pollution-driven red tides, and algae blooms that have destroyed seagrass beds the species rely upon. Starvation resulting from the loss of seagrass beds was the cause of death for more than 1,000 manatees in 2021, prompting wildlife officials to feed them cabbage and lettuce as a last resort to keep […]

(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 10, 2023) Scientists are uncovering more information about a fungal pathogen behind a disease outbreak in Indian hospitals that sickened 10 pre-term infants. According to a study published in mBIO late last month, the yeast pathogen Lodderomyces elongisporus was the causative agent of this outbreak and is rapidly evolving resistance to control measures. There is growing concern globally over the spread of fungal pathogens, with scientists increasingly identifying agriculture as the driver behind pathogenic mutations and resistance. Scientists in Delhi, India were called to investigate an outbreak of L. elongisporus that sickened ten infants with low birthweight in the neonatal intensive care unit (NICU) from September 2021 to February 2022. L. elongisporus is more commonly known for attacking severely immunocompromised adults, including those with heart conditions or a history of intravenous drug use. However, there are an increasing number of reports of fungal infections in neonatal care units. Further, the fungus appears to be spreading globally, with reports of infections in the Middle East, Europe, Australia, and North America. “This yeast is among a growing list of fungi capable of causing severe infections among humans,” said lead study author Jianping Xu, PhD a professor at McMaster University […]

(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, 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 27, 2023) The Nevada Assembly, by unanimous vote, took the state one step closer to banning the use of neonicotinoid insecticides used on plants, with a waiver for commercial agricultural purposes. Despite dramatic declines in bee populations linked to neonicotinoid pesticides and other toxic pesticides, the U.S. Environmental Protection (EPA) and state regulatory authorities have for the most part ignored beekeepers and the independent scientific literature by allowing widespread toxic pesticide use—forcing elected officials to take protective action. Portions of the bill would take effect upon passage or no later than January 1, 2024. Maine and New Jersey have adopted similar legislation. The failure to adequately regulate pesticides under federal law, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and EPA inaction is viewed by environmentalists as the shocking disregard for the importance of biodiversity to sustaining life. The inadequate restriction of pesticides and slower than necessary transition to organic land management practices are viewed as major contributors to the “insect apocalypse.” The legislation (A.B. 162), led by Assemblywoman Michelle Gorelow and a group of nine other Assemblymembers, illustrates a growing trend of local and state legislative bodies asserting their authority to protect against health, biodiversity, and […]

(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 […]

(Beyond Pesticides, April 20, 2023) This Earth Day (Saturday, April 22, 2023), Beyond Pesticides urges individuals to spread awareness of the toxic pesticides that poison people and the environment and the safe alternatives that are available to safeguard communities and the surrounding environment. On Earth Day, reflecting on the beauty and wonder of the natural world highlights the importance of restoration and preservation to maintain the planet’s intricate web of life. However, the natural world on which life depends is under dire threat as the dependence on toxic chemicals (e.g., pesticides) enables ongoing environmental contamination. Mechanized and industrial human activity perpetuates ongoing toxic chemical contamination, resulting in massive die-offs of beneficial organisms, increased rates of autoimmune diseases, endocrine disrupting and transgenerational chemical effects, and widespread pollution of our air and waterways. Beyond Pesticides, has the tools needed to increase environmental awareness in your community. Therefore, this Earth Day, Beyond Pesticides continues to advocate for the adoption of organic practices and policies that alleviate threats to ecosystems and enhance biodiversity. Michigan State University professor Thomas Dietz, Ph.D. highlights, “Continuing the successes of environmentalism—an integration of science, a concern with human well-being and justice, and a recognition of the need to consider […]

(Beyond Pesticides, April 18, 2023) Crop diversification is effective at reducing pest abundance in growing climates across the globe, according to a meta-analysis published this month in the Journal of Applied Ecology. The meta-analysis, which includes a review 44 field studies from six continents, provides greater weight to approaches that work with natural processes, rather than those focused on human-made chemical sprays for pest management. Within the studies reviewed, researchers aimed to understand the associational effects that resulted in either associational resistance (a decrease) or associational susceptibility (an increase) in insect herbivores on the primary crop being grown. Researchers reviewed a range of variables, comparing pest numbers in monocultures vs bicultures, evaluating whether the pest is a generalist or specialist, how it feeds (checking or piercing/sucking), its origin (native/non-native), as well as climate, crop type (only onions, brassicas, cotton, and cucurbits were evaluated), plot size, and the experimental design within each particular study.   In sum, the review represents one of the most comprehensive evaluations of intercropping to date. And the results confirm the benefits many farmers and gardeners across the world have found anecdotally in their own plots. “Overall, intercropping proved to be very effective against pests, but it did […]

(Beyond Pesticides, April 18, 2023) Health officials in France are alerting the public that a majority of drinking water samples tested by the government contain the presence of the highly toxic fungicide chlorothalonil. The findings highlight a stark divide between regulations and public health management in the European Union and United States. While EU member states have banned this chemical and are working to understand and address lingering effects, tens of millions of pounds of chlorothalonil continue to be sprayed throughout the U.S. annually. French officials say they conducted this research after researchers in Switzerland found evidence of the fungicide in drinking water. A few years ago, Swiss scientists released a report showing Evian bottled water, touted for its claims of purity, was found to contain measurable levels of chlorthalonil.  “The fact that even the Evian springs in the French Alps, which are hardly affected by humans, contain pesticide residues is alarming and shows the far too careless handling of these substances,” Roman Wiget, president of the international drinking water association AWBR told the German-language Swiss weekly at the time. The EU banned uses of chlorothalonil in 2019, due to concerns over water contamination, the effects of such contamination on fish […]

(Beyond Pesticides, April 14, 2023) In March, scientists at the National Marine Fisheries Service (NMFS) issued a draft Biological Opinion (BiOp) stating that carbaryl and methomyl — two commonly used carbamate insecticides — cause significant harm to dozens of already-endangered fish species in the Pacific Northwest’s Columbia, Willamette, and Snake rivers. The BiOp indicates that these toxic compounds, in wide use on orchards and field vegetables throughout the Willamette Valley, the Columbia River Gorge, and southeastern Washington, will likely threaten scores of species on the Endangered Species list: 37 species at risk from carbaryl and 30 from methomyl. In addition, the BiOp says, “both are likely to harm or destroy many areas designated as critical habitat for endangered species.” The mitigation measures proposed by NMFS and the U.S. Environmental Protection Agency (EPA), in light of this BiOp, are likely to be inadequate to the problem, given that both compounds can drift through air and/or migrate into groundwater and generate toxic runoff. These two neurotoxic insecticides, carbaryl and methomyl, are very toxic to bees, birds, fish, and other aquatic organisms. In addition, carbaryl is a likely human carcinogen and an endocrine disruptor, and has harmful impacts on multiple bodily systems. Methomyl is […]
