(Beyond Pesticides, July 11, 2023) A study published in Parkinsonism & Related Disorders finds high exposure to household pesticides increases the risk of developing Parkinson’s disease (PD) two-fold. There is a multitude of epidemiologic research on Parkinson’s disease demonstrating several risk factors, including specific genetic mutations and external/environmental triggers (i.e., pesticide use, pollutant exposure, etc.). However, several studies find exposure to chemical toxicants, like pesticides, has neurotoxic effects or exacerbates preexisting chemical damage to the nervous system. Past studies suggest neurological damage from oxidative stress, cell dysfunction, and synapse impairment, among others, can increase the incidence of PD following pesticide exposure. Despite the widespread commercialized use of household pesticides among the general population, few epidemiologic studies examine the influence household pesticides have on the risk of PD, although many studies demonstrate the association between PD onset via occupational (work-related) pesticide exposure patterns. Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans living with PD and about 50,000 new diagnoses annually. Alzheimer’s ranks first. The disease affects 50 percent more men than women, and individuals with PD have a variety of symptoms, including loss of muscle control and trembling, anxiety and depression, constipation and urinary difficulties, dementia, and […]

(Beyond Pesticides, June 28, 2023) An autopsy report from the Broward County Medical Examiner’s office in Florida found that acute exposure to the fumigant sulfuryl fluoride resulted in the death of two pest control workers from Pompano Beach. After the fumigation of a Pompano Beach warehouse in April, three workers fell ill, and two died after pesticide application. The highly toxic chemical can be used by the chemical pest control industry for killing termites, powder post beetles, old house borers, bedbugs, carpet beetles, moths, cockroaches, rats, and mice. In addition to being highly acutely toxic, sulfuryl fluoride, as a fluoride compound, can cause various chronic adverse health effects, including cancer, endocrine disruption, neurotoxicity (reduced IQ), and reproductive damage. This case represents the broader issue of how toxic chemical compounds can enter the body, causing physiological damage. In fact, just last March 2023, a case report article published in Frontier in Public Health confirms one of the first reported deaths from inhalation of the fumigant 1,3-dichloropropene (1,3-D or Telone) during work, resulting in acute renal (kidney) failure, hyperkalemia (high potassium levels in the blood), and brain edema (swelling). Considering over 300 environmental contaminants and their byproducts, including pesticides, are chemicals commonly present in human blood and urine samples, toxicity risk increases when entering the […]

(Beyond Pesticides, June 21, 2023) Pollinators––bees, butterflies, birds, bats, and other organisms––make a critical contribution to plant health, crop productivity, and the preservation of natural resources. However, pesticides consistently act as a key contributor to dramatic pollinator declines. Much research attributes the decline of insect pollinators over the last several decades to the interaction of multiple environmental stressors, from climate change to pesticide use, disease, habitat destruction, and other factors. Roughly a quarter of the global insect population has disappeared since 1990, according to research published in the journal Science. Monarchs are near extinction, and beekeepers continue to experience declines that are putting them out of business. We continue to lose mayflies, the foundation of many food chains, and fireflies, the foundation of many childhood summer memories. The declines in many bird species likely have close links to insect declines. Recent research finds that three billion birds, or 29% of bird abundance, have been lost since the 1970s. In a world where habitat loss and fragmentation show no sign of abating, scientists have concluded that the globe cannot afford to continue to subject its critically important wild insects to these combined threats.  Clean air, water, and healthy soils are integral to ecosystem function, interacting between Earth’s four main spheres (i.e., hydrosphere, […]

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

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

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

(Beyond Pesticides, 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 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 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 […]

(Beyond Pesticides, April 12, 2023) Spring represents a period of increased water, soil, and general ecosystem pollution, correlated with increased pesticide use and increased rainfall. Thus, April showers bring May flowers, and often pesticides. We offer this overview to share with friends, family, and your community in an effort to elevate the urgent need to eliminate pesticides and make the shift to organic land management. Pesticides are pervasive in the environment, affecting all ecosystems, including air, water, and soil. Like clean air and water, healthy soils are integral to ecosystem function, interacting between Earth’s four main spheres (i.e., hydrosphere, biosphere, lithosphere, and atmosphere) to support life. Pesticide use results in pervasive contamination of treated and nontarget sites. Even organic farmers and gardeners globally suffer from the widespread movement of pesticides through the air, water, and runoff from land. Attempts to protect property and ecosystems from pesticide use are a difficult, some say impossible, challenge. Efforts to prevent contamination become a large burden, with attempts to curtail pesticide drift with buffer zone areas and eliminate fertilizers or soil supplements with pesticide residues (e.g., manure and compost). Furthermore, the effects of climate change only exacerbate threats to ecosystem health, as studies show a […]

(Beyond Pesticides, April 11, 2023) Natural areas are often considered more pristine than urbanized locations, but a new study published in Nature Communications shows that the soils in natural lands can be just as polluted as those in more densely populated cities. The findings underscore the broad impacts that human activity is having on the health and stability of natural systems around the globe. In order to address widespread contamination, advocates urge government regulators to consider the full cradle to grave life cycle of toxic materials before releasing them into the environment. An international contingent of scientists came together to conduct this research on a global scale, looking at soils on every continent. Soil samples were collected from urban greenspaces and nearby natural areas and paired together. Sampling was conducted in 56 cities in 17 countries, representing six continents. These data were also compared to soil samples taken from remote ecosystems in Antarctica. Scientists tested soils for eight heavy metals, 46 pesticide residues, microplastics, and antibiotic resistance genes. Results reveal a wide distribution of tested contaminants in all samples taken. “Although the level of individual contaminants varied greatly across locations, we detected significant correlations among each type of soil contaminants […]

(Beyond Pesticides, March 14, 2023) A study published in Environmental Research and Public Health finds occupational pesticide exposure increases the risk of sleep disorders among farmworkers and pesticide applicators. Specifically, many pesticides, like organophosphates (OPs), are detrimental to neurological function through inhibition of the enzyme acetylcholinesterase (AChE) responsible for ending a neurotransmission event after relaying the necessary information. Without an end to neurotransmission events, individuals experience a buildup of acetylcholine, resulting in convulsions, headaches, weakness, impacts on bodily senses, and other cognitive/mental changes. In addition to illnesses from chemical exposure, inadequate sleep has links to several chronic diseases like type 2 diabetes, cardiovascular disease, obesity, and depression. Therefore, given research links to sleep-related disorders and bodily functions, including endocrine, metabolic, neurological, and cognitive disorders, studies like this can help government and health officials identify how pesticides’ impact on the brain elevates health concerns. The study notes, “The study’s findings can be used to create strategies for addressing mental health issues and promoting mental health and quality of life.” Researchers assess the sleep patterns among individuals living in southeast Spain, near the coast of Almeria, where chemical-intensive agriculture from greenhouses is prevalent. Of the 380 participants in the study, 189 were […]

(Beyond Pesticides, March 6, 2023) After the Trump EPA was blocked from weakening the application exclusion zone (AEZ) provisions for protecting farmworkers, the rules reverted to the Obama era rules. Now, EPA proposes to reaffirm part of that rule, while accepting some of the weakening amendments from the Trump administration. Tell EPA to strengthen pesticide rules to protect farmworkers. Tell President Biden to sign the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families.    EPA’s Worker Protection Standards (WPS) are rules that govern labor safety standards within federal pesticide law (the Federal Insecticide Fungicide and Rodenticide Act, or FIFRA). Farmworkers are not covered for toxic chemical exposure by the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA), and WPS have long been criticized by farmworker, labor, and health advocates for providing insufficient protections for farmworkers, their children and communities. Under the WPS, AEZs are buffer zones where people are not allowed to enter during the course of a pesticide application. Like all buffer zones, they are designed to allow application of toxic pesticides while providing a nominal degree of protection. Pesticides drift long distances when being applied and they […]

(Beyond Pesticides, February 28, 2023) The Environmental Protection Agency (EPA) filed a proposed rule this month to update the way farmers, farmworkers, and bystanders are protected from toxic pesticide applications. The rule, which governs “Application Exclusion Zones” (AEZs), is being put forth to reinstate an Obama-era rule with the addition of some new industry-friendly provisions. EPA characterizes a return to the past with the adoption of former protections, after a period of deep deregulation under the Trump Administration, as a step forward in protecting farmworkers from toxic exposure. “EPA’s top priority is to protect public health and the environment, and today’s proposal is a significant step forward to further protect the farmworkers, farmers and pesticide handlers who deliver the fuel, fiber and food that runs America,” said EPA Administrator Michael S. Regan. “Farmworker justice is environmental justice, and we’re continuing to take action to make sure these communities are protected equally under the law from pesticide exposure.” However, within the historical context of this proposal, it appears as though the agency will end up with rules that are weaker, and more industry-friendly than those currently in place before the Trump Administration. AEZs are buffer zones where individuals are not allowed […]

(Beyond Pesticides, February 13, 2023) As more and more communities across the country outlaw pesticides on their public land, parks, and playing fields, most states prohibit (or preempt) localities from restricting hazardous use on private property. As a result, pesticides used on landscapes—uses that can be replaced by organic management practices—result in chemical drift and runoff, putting the community in harms way and people involuntarily exposed. The Protect America’s Children from Toxic Pesticides Act of 2023 (PACTPA), S.269, includes a provision that grants communities under federal pesticide law (the Federal Insecticide, Fungicide, and Rodenticide Act—FIFRA) local authority to restrict pesticides on all property, public and private, within their jurisdiction. While the U.S. Supreme Court (in Wisconsin Public Intervenor v. Mortier) in 1991 found that FIFRA does not preempt local governments’ authority to restrict pesticide use in their town, cities, or counties, state governments have taken that authority away in 44 states at the behest of the pesticide lobby. Urge your Senators to co-sponsor PACTPA and reforms to the toxic core of FIFRA, including upholding the right of local governments to restrict pesticides. As local governments debate the hazards associated with pesticide use in their communities, many have decided to transition their […]

(Beyond Pesticides, February 10, 2023) The U.S. Environmental Protection Agency (EPA) announced, on February 1, new measures to protect 28 endangered salmon species (including steelhead trout) from the use of four pesticides that threaten them and their critical habitats. Those compounds comprise three herbicides — metolachlor, bromoxynil, and prometryn, and one soil fumigant, 1,3-Dichloropropene. The protections, aimed at salmon populations in Washington, Oregon, and California, are meant to reduce impacts from pesticide runoff and spray drift, and to minimize potential “take.” (Under the Endangered Species Act (ESA), “take” means, essentially, the unintentional harming or killing of an individual of a protected species — in this case, harm or death from exposures to these toxic pesticide compounds.) Beyond Pesticides and other advocates have for years warned that multiple pesticides are threats to Northwest salmon and other species at risk. This EPA announcement is the second of two, recently, that offer slight redress to the agency’s historical failures to act (see more below). Indeed, advocates have engaged in multiple litigation efforts over the years to try to force EPA to take action; EarthJustice in 2001 noted some early instances. As Chemical and Engineering News says pointedly, “Environmental groups, which have been suing […]

(Beyond Pesticides, February 9, 2023) Business Insider India reports over 100 infant deaths from pesticide exposure in breast milk. A study by Lucknow’s Queen Mary Hospital links pesticides in breast milk to the death of 111 newborns over the past ten months in the Maharajganj district of northern India. The study is a testament to the effects pesticides can have on the health of individuals, especially vulnerable populations like infants and shows that there is a long way to go before our bodies are void of any bioaccumulated toxic residues. Multiple studies on breast milk throughout the years confirm that toxic chemicals build up in our bodies as breast milk can bioconcentrate or accumulate, a natural phenomenon dubbed chemical “body burden.” Hundreds of chemicals are in blood, urine, breast milk and umbilical cord blood, entering our bodies through diet, personal care product use, and inhalation from air. Many known pollutants (i.e., heavy metals, polychlorinated biphenyl, and pesticides) are chemicals that can move from the mother to the developing fetus at higher exposure rates. Hence, prenatal exposure to these chemicals may increase the prevalence of birth-related health consequences like natal abnormalities and learning/developmental disabilities. Children are particularly vulnerable to the impacts of pesticide exposure as their developing […]

(Beyond Pesticides, February 1, 2023) A study published in Environment International concurs with previous reports that agricultural pesticide treatment can contaminate nearby residential areas, resulting in indoor chemical exposure via concentrations of insecticide active ingredients in house dust. Pesticide contamination in homes has ties to higher levels of pesticide residue in both human and pet bodies. Some pesticides, like organochlorine compounds, have poor elimination from the body, leading to accumulation over a lifetime. Pesticide exposure can heighten risks of various cancers (i.e., prostate, hepatic, liver, etc.), mental health problems (i.e., depression), respiratory illnesses (asthma), endocrine disruption, and many other pesticide-induced diseases. Extensive pesticide use can predispose human pathogenic to antibiotic resistance, bolstering bacterial virulence. Studies like this are concerning as it reveals that individuals do not have to be in close contact (e.g., chemical manufacturers, farmworker, gardener, custodian, etc.) with pesticides for risky, health-harming exposures to occur. Despite stricter regulations and technological changes beginning to decrease air pollution from cars and other vehicles, scientists are finding that the use of pesticides and other household chemicals represents an increasing proportion of U.S. smog-forming air pollution. Personal care products, cleaning agents, perfumes, paints, printing ink, and pesticides warrant greater attention from regulators for their ability to form toxic fumes that can eventually make their way […]

(Beyond Pesticides, January 12, 2023) Exposure to certain pesticides among individuals diagnosed with Parkinson’s disease (PD) can increase the risk of symptom progression. According to a study published in Science of the Total Environment, nearly 20 percent of pesticides associated with the onset of PD also increase the risk of faster decline in motor and non-motor function. Several studies find exposure to chemical toxicants, like pesticides, has neurotoxic effects or exacerbates preexisting chemical damage to the nervous system. Past studies suggest neurological damage from oxidative stress, cell dysfunction, and synapse impairment, among others, can increase the incidence of PD following pesticide exposure. Despite the association between PD onset via pesticide exposure patterns, few epidemiologic studies examine the influence pesticides have on worsening motor and non-motor symptoms in PD. Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans living with PD and about 50,000 new diagnoses annually. The disease affects 50 percent more men than women, and individuals with PD have a variety of symptoms, including loss of muscle control and trembling, anxiety and depression, constipation and urinary difficulties, dementia, and sleep disturbances. Over time, symptoms intensify, but there is no current cure for this fatal disease. While […]

(Beyond Pesticides, December 6, 2022) Persistent organic pollutants (POPs)—including banned pesticides—present a health risk to humpback whales (Megaptera novaeangliae), according to a study published in Environmental Pollution. Regarding female humpback whales, levels of POPs in blubber are higher in juveniles and subadults than in adults, primarily from the transference of contaminants from the mother to her calf.  Organochlorine compounds (OCs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are well-known persistent organic pollutants. The international Stockholm Convention treaty (signed by 152 countries, but not the U.S.) banned these primary pollutants of concern (UNEP, 2009) in 2001 (taking effect in 2004) because of their persistence, toxicity, and adverse effects on environmental and biological health. These pollutants have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. However, these chemicals can remain in the environment for decades and interact with various current-use pesticides, including organophosphates, neonicotinoids, and pyrethroids. Although various studies demonstrate the volatile, toxic nature of POPs, much less research evaluates the impact POPs have on maternal offloading or transfer of contaminates to offspring and respective health consequences. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one […]
