(Beyond Pesticides, April 22, 2024) Today, on Earth Day, the future of the planet and the health of all its inhabitants come into focus from numerous human and ecosystem health perspectives, with particular concern for the health of the next generation—as childhood cancer continues to be a leading cause of death from disease among children. Many studies demonstrate an association between environmental or occupational pesticide exposure and the risk of childhood cancer in offspring. Taking Action in Your Community: On Earth Day, Beyond Pesticides invites communities to join together in its nationwide campaign to convert parks to organic land management practices through the Parks for a Sustainable Future program. Through this program, Beyond Pesticides works with park managers, bringing hands-on horticultural support to eliminate petrochemical pesticides and fertilizers and instead nurture soil organisms to cycle nutrients naturally while creating resilient landscapes that resist weeds, insects, and disease. This program outlines the steps to become a parks advocate and how Beyond Pesticides works with communities committed to safe parks and playing fields for communities, children, and pets. One major impetus for the Parks program are the many studies that find prenatal and early-life exposure to environmental toxicants increases disease susceptibility. For decades, studies have […]

(Beyond Pesticides, April 1, 2024) Comments are due 11:59 pm EDT, Wednesday, April 3. For the public comment period—deadline Wednesday, April 3—in the lead up to the National Organic Standard Board (NOSB) meeting, advocates have identified the following priority issues: Getting plastics our of organic; Removing endocrine disrupting nonylphenols (NPs) and nonylphenol ethoxylates (NPEs) iodine from dairy production and replace with available alternatives; and Continuing to improve the science supporting ongoing decisions of the NOSB. (See below for details and opportunity to submit comments on these with one click!) Previously, Beyond Pesticides has reported on three additional priority issues, including; Reject the petition to allow unspecified “compostable materials” in compost allowed in organic production; Eliminate nonorganic ingredients in processed organic foods as a part of the Board’s sunset review of allowed materials; and  Ensure that so-called “inert” ingredients in the products used in organic production meet the criteria in OFPA with an NOSB assessment.  (Please see the prior action on these issues and submit comments, if not done previously.) Beyond Pesticides asks the public to join in commenting on priority issues that protect health and the environment as part of the upcoming NOSB meeting. The NOSB is receiving written comments from the […]

 (Beyond Pesticides, March 14, 2024)  A recent review in the New England Journal of Medicine (NEJM) highlights the urgent need to address the widespread chemical pollution stemming from the petrochemical industry, underscoring the dire implications for public health. Tracey Woodruff, PhD, author and professor at the University of California San Francisco (UCSF), emphatically states in an email comment to Beyond Pesticides, “We need to recognize the very real harm that petrochemicals are having on people’s health. Many of these fossil-fuel-based chemicals are endocrine disruptors, meaning they interfere with hormonal systems, and they are part of the disturbing rise in disease.” Beyond Pesticides echoes this concern, noting that endocrine disrupting chemicals (EDCs) include many pesticides and are linked to a plethora of health issues such as infertility, diabetes, cardiovascular diseases, obesity, early puberty, as well as attention deficit hyperactivity disorder (ADHD), Parkinson’s, Alzheimer’s, and childhood and adult cancers.  (See Beyond Pesticides’ Disease database here and news coverage here). The review further calls on the clinical community to advocate for policy changes aimed at mitigating the health threats posed by petrochemical-derived EDCs and climate change. Beyond Pesticides urgently calls for the elimination of petrochemical pesticides and fertilizers and advocates for a systemic […]

(Beyond Pesticides, March 4, 2024) With 14.7 million children and adolescents in the U.S. recognized as obese by the Centers for Disease Control and Prevention (CDC) and the established connection with endocrine disrupting contaminants, including many pesticides, Beyond Pesticides is calling on federal food assistance programs to go organic. The problem of childhood obesity is higher in people of color and, as a result, is an environmental justice issue. According to CDC, the prevalence of childhood obesity is “26.2% among Hispanic children, 24.8% among non-Hispanic Black children, 16.6% among non-Hispanic White children, and 9.0% among non-Hispanic Asian children.” While childhood obesity is recognized as a serious problem, the National School Lunch Program of the U.S. Department of Agriculture (USDA)—although improved by the Healthy, Hunger-Free Kids Act of 2010—still provides lunches laced with obesogenic pesticides. To take meaningful steps against childhood obesity, school lunches must be organic. The program served 4.9 billion meals in fiscal year 2022 in over 100,000 public and nonprofit schools, grades Pre-Kindergarten-12. Contrary to popular opinion, the blame for the obesity epidemic cannot be attributed solely to diet and exercise broadly, but relates directly to pesticide and toxic chemical exposures, including residues in food, that may lead […]

(Beyond Pesticides, February 21, 2024) In addition to its effects including cancer, and reproductive, immune or nervous system disruption, according to international findings, a review published in Toxics finds that the the widely used weed killer 2,4-dichlorophenoxyacetic acid (2,4-D) causes significant changes in liver structure and function. 2,4-D can damage liver cells, tissue, and inflammatory responses through the induction of oxidative stress. The liver, the largest solid organ in the human body, is an essential part of the digestive system responsible for blood detoxification, nutrient metabolization, and immune function regulation. However, rates of chronic liver diseases are increasing, representing the second leading cause of mortality among all digestive diseases in the U.S. In fact, researchers warn of the rise in liver disorders and metabolic syndrome among young people. Therefore, reviews like this highlight the research available to make decisions on safeguarding human health from chemical exposure to mitigate further disease outcomes and complications. 2,4-D is used on turf, lawns, and rights-of-way, as well as in forestry and aquatic systems. 2,4-D products are available as liquid, dust, and granule fields, as well as fruit and vegetable crops, including in genetically engineered crop production. The chemical is widely used in “weed and feed” lawn products. It is […]

(Beyond Pesticides, February 20, 2024) With health risks including developmental, metabolic, cardiovascular, and reproductive harm, cancer, damage to the liver, kidneys, and respiratory system, as well as the potential to increase the chance of disease infection and severity, per- and polyfluoroalkyl substances (PFAS) and their toxic trail of contamination in the environment is wreaking havoc with all life. The use of PFAS in industrial and commercial applications has led to widespread contamination of water and biosolids used for fertilizer, poisoning tens of millions of acres of land and posing a significant threat to the biosphere, public health, gardens, parks, and agricultural systems. Farmers and rural communities, in particular, bear the brunt of this contamination, as it affects their drinking water, soil quality, and livestock health.   Tell Congress that the Farm Bill must include the Relief for Farmers Hit with PFAS Act and the Healthy H2O Act to protect farmers and rural communities from PFAS contamination.  Led by Chellie Pingree (D-ME), U.S. Senators Tammy Baldwin (D-WI), and Susan Collins (R-ME), a bipartisan and bicameral bill—the Relief for Farmers Hit with PFAS Act—has been introduced to provide assistance and relief to those affected by PFAS. A second bill, the Healthy H2O Act, introduced by Representatives Pingree and David Rouzer (R-NC) and Senators Baldwin […]

(Beyond Pesticides, February 9, 2024) EPA is accepting public comments through today, Friday February 9, on its long-held policy of exempting “treated objects,” including seeds and paint, from pesticide registration. Although EPA does not ask the most important question—“Should pesticide-treated seeds and paint be exempt from the scrutiny given pesticide products?”—this comment period offers an opportunity to respond to EPA’s questions and express concern about hazards associated with chemical use and product ingredients. Despite exposure patterns associated with the use of pesticides in treated objects that are linked to environmental contamination and human poisoning, EPA is focused on labeling and not regulation. Instead of focusing on the exposure and harm associated with the object’s use—whether treated seeds poison pollinators, soil, and water or whether paint treated with fungicides poisons people exposed to the paint—EPA takes the position that unless the manufacturer makes a pesticidal claim, the object is not regulated as a pesticide for its pesticidal effects.  Beyond Pesticides states: At the very least, if EPA deems the hazards associated with the use of the pesticide in the treated article acceptable, then the agency should disclose the chemical used in the treatment (of the seed or the paint) and require […]

(Beyond Pesticides, February  6, 2024) A study published in Occupational and Environmental Medicine finds that pesticide exposure, especially during puberty, can play a role in ovarian cancer development among female farmers. Although there are many studies that evaluate the risk for cancers among farmers, very few pieces of literature cover the risk of ovarian cancer from pesticide exposure. Additionally, this study notes suggests the role of hormones in ovarian cancer prognosis and development, highlighting an association with endocrine disruption. Exposure to past and current-use endocrine-disrupting chemicals (EDCs), like pesticides, has 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 cancer, among other health issues. The study evaluates a […]

(Beyond Pesticides, February 5, 2024) Public Comment Period Ends February 26, 2024. The U.S. Environmental Protection Agency (EPA) never completed protocol for testing pesticides that disrupt the fundamental functioning of organisms, including humans, causing a range of chronic adverse health effects that defy the common misconception that dose makes the poison (“a little bit won’t hurt you”)—when, in fact, minuscule doses (exposure) wreak havoc with biological systems. After a nearly two decade defiance of a federal mandate to institute pesticide registration requirements for endocrine disruptors, EPA has now opened a public comment period ending February 26, 2024 and advocates are criticizing the agency’s proposed evaluation as too narrow. A detailed examination of EPA’s proposal can be found in draft comments by Beyond Pesticides.  Endocrine disruption as a phenomenon affecting humans and other species has been critically reviewed by many authors. Endocrine disruptors are chemicals that can, even at extremely low exposure levels, disrupt normal hormonal (endocrine) function. Such endocrine disrupting compounds (EDC) include many pesticides, exposures to which have been linked to infertility and other reproductive disorders, diabetes, cardiovascular disease, obesity, and early puberty, as well as attention deficit hyperactivity disorder (ADHD), Parkinson’s, Alzheimer’s, and childhood and adult cancers. EPA […]

(Beyond Pesticides, January 30, 2024) The City Council of Brighton and Hove (England) is preparing to expand the use of glyphosate after widespread public complaints over the growth of Japanese knotweed and a program of manual clearance. This imminent local land management decision flies in the face of substantial research on the health and ecological impacts of glyphosate-based herbicides, including from Aaron Blair, PhD—former chair of the International Agency for Research on Cancer (IARC) working group on glyphosate and former branch chief (now scientist emeritus) of the Occupational Studies Section, National Cancer Institute (NCI). Advocates are concerned that the city council is basing this rationale on the fact that the European Commission reapproved use of glyphosate in 2023 for a ten-year period and not the body of scientific literature on health and ecosystem effects as well as alternative practices and products. According to a recent ENDS Report, “The [City of Brighton and Hove] council banned the use of glyphosate in 2019 – with an exception for killing invasive species [‘in exceptional cases’] such as Japanese Knotweed – after it was linked to health concerns and a decline in bee populations. As part of this it was agreed that the removal […]

(Beyond Pesticides, January 24, 2024) A study published in Environmental Sciences Europe finds that 2,4-D, pyrethroid (PRY), and organophosphate (OP) pesticides increase the risk of cancer through oxidative stress (OS). The study highlights that pesticides that increase cancer risk also raise inflammation biomarkers that indicate damage to organs (e.g., liver) via oxidative stress. Additionally, different cancers show different sensitivities to pesticides; thus, cancer risk changes with exposure concentration and pattern. Despite a plethora of studies linking cancer and pesticide exposure, very few cover the mechanisms involved in cancer development, including OS. Only five to ten percent of cancers are hereditary. However, environmental or lifestyle factors, like chemical exposure, can make an individual more susceptible to cancer development through gene mutation. In fact, a vast amalgamation of research links cancer risk to pesticide exposure, which augments the risk of developing both common and rare cancers. Therefore, studies like this highlight the importance of understanding how pesticide use can increase the risk of latent diseases, which do not readily develop upon initial exposure. Using data from the National Health and Nutrition Examination Survey (NHANES), researchers investigated the link between the risk of several cancers and pesticide exposure. The researchers also thoroughly evaluated […]

(Beyond Pesticides, January 19, 2024) A study published in Environmental Health Perspective is one of the first to indicate a link between exposure to the herbicides 2,4-D and glyphosate and the impairment of behavioral performance (i.e., attention/inhibitory control, memory/learning, language, visuospatial processing, and social perception). These adverse effects associated with the neurotoxic impacts of pesticides on behavior have been previously documented. For example, a study in August 2023 finds oral intake (e.g., eating contaminated foods), inhalation, and dermal exposure to glyphosate lowered cognitive function scores, increased the likelihood of severe depressive symptoms, and impaired auditory (hearing) function. Although previous studies find neurotoxic effects from exposure to these herbicides, very few until now have evaluated how this neurotoxic exposure impacts neurotypical behavior among youth (children and teenagers). The ubiquitous use of glyphosate and 2,4-D use in agriculture—which leaves residues of the toxic chemicals in food and in public areas (e.g., parks and walkways) creates a creates a significant risk for exposure. Glyphosate is already implicated in or proven to lead to the development of numerous health anomalies, including cancer, while 2,4-D also has a range of potential hazards, including cancer. Therefore, studies like this help local and government officials make holistic decisions regarding the use […]

(Beyond Pesticides, January 10, 2024) Exposure to endocrine-disrupting chemicals (EDCs) negatively impacts testicular function and may cause sperm count declines over time, according to a 2022 review published in Endocrine. The findings indicate that this occurs regardless of whether exposure is prenatal (before birth) or postnatal (after birth). More recent work from October 2023 confirms the connection between male reproductive health and exposure to organophosphate and carbamate insecticides and the weed killer glyphosate—as many pesticide products containing these chemicals are classifiable as endocrine disruptors (ED). Just last year, a meta-analysis from researchers at Mount Sinai Medical Center, the Hebrew University of Jerusalem, and the University of Copenhagen, among others, finds that the drop in global sperm count is accelerating, dropping by 51.6 percent from 1973 through 2018. The U.S. regulatory system, under the authority of the U.S. Environmental Protection Agency (EPA), has not kept pace with the science and does not fully evaluate pesticides in wide use for endocrine disruption, despite a requirement in 1996 law (the Food Quality Protection Act) to begin that testing and evaluation nearly three decades ago. In 2021, Beyond Pesticides reported that the Office of the Inspector General (OIG) for EPA issued a damning report on the […]

(Beyond Pesticides, December 15, 2023) Drawing on a recent gathering of international scientists, a group of 34 scientists published a call for much stricter scrutiny of researchers’ conflicts of interest by agencies that regulate and register chemicals, with recommendations for the newly formed Intergovernmental Science Policy Panel. Writing in Environmental Science & Technology, the authors, led by Andreas Schäffer of Aachen University in Germany and Martin Scheringer of Masaryk University in the Czech Republic, cite an abundance of examples of chemical companies and their trade associations manufacturing doubt via an array of techniques, resulting in agencies such as the U.S. Environmental Protection Agency (EPA) dropping certain provisions from rulemaking, ignoring scientific consensus, and keeping chemicals on the market—and in the environment—that many scientists say should be entirely banned. The authors produced the article in response to this webinar to discuss how to ensure that U.N. panels dealing with global crises get the most sound scientific advice conducted by the International Panel on Chemical Pollution. Over the last four decades or so, the notion that conflicts of interest affect the validity of scientific research and professional opinions has been steadily eroded. Regulators wallow in compromised research, hamstrung by political pressure and […]

(Beyond Pesticides, December 13, 2023) A study published in Environmental Health finds occupational (work-related) exposure to pesticides increases the risk of endometrial (uterine) cancer development. Endometrial cancer is the most common cancer of the female reproductive system and the fourth most common cancer among women, primarily affecting the uterine lining rather than the uterus itself, like uterine sarcoma. Despite data predicting the disease rate to increase, few studies evaluate the connection environmental contaminants have on endometrial cancer occurrence. Like most cancers, non-genetic factors account for a majority of endometrial cancer risk, including diabetes, age, contraceptive (birth-control) use, and hormone (endocrine) disruption. However, three percent of all cases are hereditary, primarily from Lynch syndrome. The study notes, “Identifying other modifiable risk factors may help develop strategies to reduce the expected increasing incidence of these neoplasms.” Many pesticides have a long history associated with endocrine-disrupting properties that induce various molecular changes, prompting disease development. The International Agency for Research on Cancer (IARC) classifies many of these chemicals as potent carcinogens in animal studies. Cancer development also depends on genetic susceptibility, as impaired genes responsible for xenobiotic detoxification (elimination) increase disease risk sensitivity. Adding to the science, a review published in Environmental Exposure, Biomonitoring, and Exposure […]

(Beyond Pesticides, December 7, 2023) A new review published in Ecotoxicology reiterates what past studies have repeatedly stated: the herbicide paraquat (PQ) has profound adverse effects on wildlife at environmentally relevant concentrations. Moreover, these adverse effects span beyond the wilderness, as exposure to this highly toxic herbicide also impacts the health of people working with this chemical (e.g., pesticide applicators) or living adjacent to areas of chemical use. Current data gaps regarding the effects of environmentally relevant concentrations and exposure times, population- or ecosystem-level effects, and biomagnification potential contribute to the uncertainty of predicting risk from environmental PQ exposure. Furthermore, Beyond Pesticides has previously pointed out deficiencies in the U.S. Environmental Protection Agency’s (EPA) ecological risk assessments for paraquat, highlighting failures to perform complete evaluations of the impacts of pesticides on threatened and endangered species. All this occurs amid documented threats to biodiversity from the combined effects of pesticides and climate change.  The review investigated paraquat in the environment, the chemical’s toxicity to nontarget species, and significant data gaps. Overall, the long-term risks of environmental PQ contamination for human and ecological communities can be challenging since the potential chronic effects from extended use are nearly unstudied. Most concerning is that PQ is […]

(Beyond Pesticides, December 6, 2023) A study published in Antioxidants finds prenatal and early life exposure, usually after birth (perinatal), to glyphosate-based herbicides (GBH) induce oxidative stress in the brain, causing damage and negatively affecting melatonin levels. Melatonin is a hormone responsible for regulating circadian rhythm to mitigate sleep disorders. Disruption of melatonin levels also has implications for the development of age-associated neurodegenerative diseases, as melatonin is a neuroprotector against neurodegenerative diseases associated with aging. Additionally, GBH can alter molecules in the pineal gland in the brain, resulting in neurodegenerative diseases like Alzheimer’s disease (AD) and Parkinson’s disease (PD). Levels of inadequate sleep patterns are rising among the global population. Reports find variability in sleep duration results in higher rates of depression, anxiety, and fatigue. Since sleep is an essential factor in normal brain development, disturbance in sleep patterns, such as sleeping too much or too little, can result in long-term associations with the brain’s white matter integrity (responsible for age-dependent cognitive function). The study warns, “Since decreased levels of the important antioxidant and neuroprotector melatonin have been associated with an increased risk of developing neurodegenerative disorders, this demonstrates the need to consider the melatonin hormone system as a central […]

(Beyond Pesticides, December 1, 2023) Even though researchers have noted since the 1970s that human fertility appears to be declining globally, doubt is still circulating that it is really happening and that pesticides could have anything to do with it. Very recently published studies, however, make it clear that, even without exact elucidation of the mechanisms by which pesticides damage male fertility, there is an unmistakable association of pesticides and many aspects of male reproductive health. One of the new studies, a meta-analysis of 25 studies on the connection between pesticides and male reproductive problems, finds that men exposed to organophosphate (such as glyphosate and malathion) and carbamate (such as carbaryl and methiocarb) insecticides have lower sperm concentrations than the general population. This is especially true of men exposed in work settings. The senior author of the study, Melissa J. Perry,ScD of the George Mason University College of Public Health, told HealthNews, “The evidence available has reached a point that we must take regulatory action to reduce insecticide exposure.” Human infertility is defined as “the failure to achieve pregnancy after 12 months or more of regular unprotected sexual intercourse.” Most public attention regarding infertility focuses on women’s difficulties in getting […]

(Beyond Pesticides, October 18, 2023) A meta-analysis published in Toxics finds an association between exposure to organophosphate pesticides (OPs) and respiratory diseases and diabetes mellitus (DM). Specifically, wheezing and asthma are the most common respiratory manifestations of OP exposure, while fluctuation in weight and fat/glucose levels are the most common metabolically related manifestations. Organophosphorus pesticides have a wide range of biological uses—from insecticides to flame retardants—that make these chemicals ubiquitous, significantly contributing to ecosystem contamination. Thus, OP compounds have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. Many studies show OPs are highly toxic, and residues are consistently present in human and animal urine, 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.  This study investigated the effects and possible mechanisms involved in adverse health outcomes associated with OP exposure. Reviewing studies from Web of Science, PubMed, Embase, OVID, and the Cochrane Library, researchers systematically searched for articles on OP exposure and respiratory, DM, and cardiovascular disease (CVD) outcomes until 2022. […]

(Beyond Pesticides, October 12, 2023) A new study published in Environment International finds novel environmental chemicals (i.e., piperidine insecticide, 2,4-dinitrophenol, benzo[a]carbazole, and a benzoate derivative) involved in developing breast cancer through various inflammation pathways. These new potential factors contribute to breast cancer and highlight the importance of employing epidemiological biomonitoring like exposome (total exposure from birth to death) to discover mechanisms involved in disease development that are otherwise overlooked. According to the Centers for Disease Control and Prevention (CDC), breast cancer is a disease that causes breast cells to grow out of control, with the type of breast cancer depending on the cells themselves. Several studies and reports, including U.S. Environmental Protection Agency (EPA) data, identify hundreds of chemicals as influential factors (either promoting or initiating) associated with breast cancer risk. Breast cancer is the most common cancer among women, accounting for 12 percent of all new annual cancer cases worldwide and causing the second most cancer-related deaths in the United States. Past studies suggest genetic inheritance factors influence breast cancer occurrence. However, genetic factors only play a minor role in the incidence of breast cancer, while exposure to external environmental factors (e.g., chemical exposure) appears to play a more notable role. One in […]

(Beyond Pesticides, October 4, 2023) A study published in Food and Chemical Toxicology finds acute exposure to chlordane, an organochlorine insecticide, results in decreased lipid (fat) levels, altered anti-oxidant capacity, and increased testosterone levels (pro-androgenic) in male mice, while increasing liver enzyme activation and reducing regulation of both liver identity and function in females. These findings indicate that chlordane induces toxicant-associated steatosis (fat retention) liver disease (TASLD) with underlying, sex-specific, endocrine, and metabolic effects. It is well-known that traces of legacy (past-use) pesticides, like organochlorine pesticides (OCPs), remain in the environment for decades—possibly centuries, post-final application, as OCPs have greater chemical stability and gradual attenuation. However, these chemicals have profound adverse impacts on human health, especially on the endocrine system. Obesity, insulin resistance, type 2 diabetes, and elevated liver enzymes resulting from endocrine disruption contribute to liver diseases and can lead to liver cirrhosis. Although some, but not all, manufacturing and use of specific OCPs have declined in the U.S., OCPs remain a global issue, as much of the developing world still report usage. Considering the lack of studies on OCP-induced endocrine disruption, TASLD, and other liver diseases, research like this highlights the need to understand the underlying mechanisms contributing to […]

(Beyond Pesticides, October 2, 2023) On the 50th anniversary of the Endangered Species Act (ESA), statements out of the U.S. Environmental Protection Agency (EPA) raise concerns about the agency’s ability to meet the challenge of evaluating pesticides for their adverse impact on threatened and endangered species. While EPA has initiated efforts to address a significant backlog of pesticide evaluations, the agency faces a task so extensive that it may require several additional decades to fully catch up. EPA officials stated, “Even if EPA completed this work for all of the pesticides that are currently subject to court decisions and/or ongoing litigation, that work would take until the 2040s, and even then, would represent only 5 percent of EPA’s ESA obligations.”   As part of a “whole of government” approach, EPA must redirect its pesticide program to protecting all species and their habitats.   The speed and depth of biodiversity loss has reached crisis proportions. A 1,500-page report in 2019 by Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES )—Global Assessment Summary for Policymakers, the most comprehensive look to date at the biodiversity crisis and its implications for human civilization, makes the following finding: “Since 1970, trends in agricultural production, fish harvest, […]

(Beyond Pesticides, September 27, 2023) A study published in Pesticide Biochemistry and Physiology finds organophosphate (OP), organochlorine (OC), and pyrethroid (PYR) pesticides have links to insulin resistance (IR) associated with metabolic disorders like diabetes, obesity, chronic kidney disease (CKD), and hypertension. Metabolic disorders are among the leading causes of morbidity and mortality, with over 11 percent (>37 million) of individuals in the U.S. having diabetes, and cases are growing by millions annually. Additionally, there is a rise in metabolic disorders among young people. Studies even find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects, including metabolic disorders tied to gut microbiome disruption (dysbiosis). With increasing rates of diabetes and obesity, the two most prominent metabolic diseases in the study, cases among the global population, studies like these highlight the importance of evaluating how chemical contaminants deregulate normal bodily function through metabolic changes.  To investigate the association between pesticide exposure and insulin-related metabolic disorders in humans, researchers searched the PubMed database for articles, performing a systematic review. The study notes, “IR is defined as a pathological state in which a higher-than-normal level of insulin is required to produce the optimal response in cells.” The search generated 4,051 articles related to the topic. However, after excluding duplicates and […]
