(Beyond Pesticides, May 27, 2021) Research by the U.S. National Institutes of Health (NIH) finds exposure to lindane and metalaxyl pesticides heightens thyroid cancer risk. Both incidents of non-aggressive thyroid tumors and advanced-stage thyroid cancer are on the rise. However, researchers speculate that environmental pollutants, such as pesticides, may contribute to this increase, especially considering the pervasiveness of pesticide exposure among the general population. Globally, cancer is one of the leading causes of death, with over 8 million people succumbing to the disease every year. Notably, the International Agency for Cancer Research (IARC) predicts new cancer cases to rise 67.4% by 2030. Various environmental pollutants like pesticides have endocrine (hormone) disruption effects that promote higher instances of thyroid and reproductive cancers. Therefore, studies like these highlight the importance of understanding how pesticide use can increase the risk of latent diseases (e.g., cancers), which do not readily develop upon initial exposure. The researchers state, “More work is needed to understand the potential role of these chemicals in thyroid carcinogenesis.” The European Union and endocrine disruptor expert (deceased) Theo Colborn, Ph.D., classify more than 55 pesticide active ingredients as endocrine disruptors (EDs), including chemicals in household products like detergents, disinfectants, plastics, and pesticides. Endocrine disruptors are xenobiotics (i.e., toxic chemical substances foreign […]

(Beyond Pesticides, May 13, 2021) Scientists are advocating for stricter pesticide bans to lower deaths from deliberate pesticide ingestion. The request for this toxic pesticide ban follows a University of South Australia study detailing discrepancies in World Health Organization (WHO) classifications of pesticide hazards that rely on animal rather than human data. Previous studies demonstrate an increased risk of developing depression, especially among agricultural workers and landscapers who use pesticides. Acute exposure to chemicals, including organophosphate and carbamate pesticides, tends to put farmers at greater risk of suicide than the general population. This research highlights the significance of assessing pesticide toxicity and health effects using human data rather than animals to understand health effects resulting from pesticide exposure. Society tends to rank mental health risks second to physical health. However, pesticide poisonings account for one in five suicides globally. Therefore, it is vital to address the accessibility and necessity of conventional pesticide use to safeguard human well-being, especially in countries lacking adequate chemical regulations. The study’s scientists note, “The human data for acute toxicity of pesticides should drive hazard classifications and regulation. We believe that a global benchmark for registration of pesticides should include a less than 5% case fatality after self-poisoning, which could prevent many […]

(Beyond Pesticides, May 7, 2021) Soil health is one of the linchpins on which the food production that sustains human life — as well as biodiversity, pollinator health, and carbon sequestration — depend. A recent meta-review of nearly 400 studies finds that, in 71% of the cases reviewed, pesticides kill or otherwise harm soil invertebrates that contribute mightily to soil health. In their paper, “Pesticides and Soil Invertebrates: A Hazard Assessment,” published in Frontiers in Environmental Science in early May, the researchers write, “A wide variety of soil-dwelling invertebrates display sensitivity to pesticides of all types . . . [These results] support the need for pesticide regulatory agencies to account for the risks that pesticides pose to soil invertebrates and soil ecosystems.” Beyond Pesticides, which has long reported on impacts of pesticides on soil health, concurs with that conclusion, and adds that the real solutions to noxious pesticide impacts lie in the adoption of  regenerative organic approaches to all land management because they obviate any need for petroleum-based toxic chemical controls. The term “pesticide” can refer to myriad kinds of chemical treatments — including antimicrobials, disinfectants, rodenticides, and others — but in the agricultural and land management realms, primarily means insecticides, […]

(Beyond Pesticides, April 22, 2021) Past maternal exposure to the pesticide dichlorodiphenyltrichloroethane (DDT) during pregnancy can increase the risk of breast cancer and cardiometabolic disorders (e.g., heart disease, obesity, diabetes) up to three successive generations, according to a new study published in Cancer Epidemiology, Biomarkers & Prevention. Although previous studies highlight early life or in utero exposure to DDT increasing breast cancer risk later in life, this study is the first to note generational effects on grandchildren’s health. DDT continues to adversely affect the health of the U.S. population, nearly 50 years after its ban. However, this ban is not global, as many countries still use or manufacture the chemical compound. Furthermore, residues of DDT metabolite, DDE, continue to readily contaminate food and water worldwide. Therefore, studies like these highlight the need to investigate how first-generation pesticide exposure can impact future generational health in order to prevent adverse health outcomes, especially during sensitive developmental periods (i.e., in utero, infancy/childhood). The study researchers note, “Discovery of actionable biomarkers of response to ancestral environmental exposures in young women may provide opportunities for breast cancer prevention.” To assess the association between multi-generational health risks and chemical exposure, researchers used the Public Health Institute’s Child […]

(Beyond Pesticides, April 21, 2021) The vast majority of bald and golden eagles in the United States are contaminated with toxic anticoagulant rodenticides, according to research published in the journal PLOS One earlier this month. Although eagle populations have largely recovered from their lows in the 1960s and 70s, the study is a stark reminder that human activity continues to threaten these iconic species. “Although the exact pathways of exposure remain unclear, eagles are likely exposed through their predatory and scavenging activities,” said study author Mark Ruder, PhD, assistant professor at the University of Georgia to CNN. Eagle carcasses were retrieved from the University of Georgia’s ongoing Southeastern Cooperative Wildlife Disease Study. Eighteen state wildlife agencies and the U.S. Fish and Wildlife Service all sent in specimens from a period spanning 2014 to 2018. In total, 116 bald eagle and 17 golden eagle carcasses had their livers tested for the presence of anticoagulant rodenticides. Out of the 116 bald eagles tested, 96, or 83% had were exposed to toxic rodenticides. Forty of the eagles  (35%) were exposed to more than one rodenticide compound. Thirteen out of 17 golden eagles were contaminated was rodenticides, with four exposed to a single rodenticide […]

(Beyond Pesticides, April 8, 2021) Pesticide use threatens aquatic and terrestrial invertebrates and plants more than ever, despite declining chemical use and implementation of genetically engineered (GE) crops in the U.S., according to a University Koblenz-Landau, Germany study. Since the publication of Rachel Carson’s Silent Spring (1962), many environmental agencies have banned the use of pesticides like organochlorines, organophosphates, and carbamates for their devastating toxic—sometimes lethal—effects, particularly on vertebrates, including humans. However, this ban created a pathway for a new generation of pesticides (e.g., neonicotinoids, pyrethroids) to take hold. Although these pesticides are more target-specific, requiring lower chemical concentrations for effectiveness, they have over double the toxic effects on invertebrates, like pollinators.  Invertebrates and plants are vital for ecosystem function, offering various services, from decomposition to supporting the food web. Furthermore, invertebrates and plants can act as indicator species (bioindicators) that scientists can observe for the presence and impact of environmental changes and stressors. Therefore, reductions in invertebrate and plant life have implications for ecosystem health that can put human well-being at risk. Study lead author Ralf Schulz, PH.D., notes, “[This study] challenge[s] the claims of decreasing environmental impact of chemical pesticides in both conventional and GM [genetically modified or genetically engineered (GE)] crops and […]

(Beyond Pesticides, April 5, 2021) The failure of EPA to meet its statutory responsibility to protect people and wildlife from the dire consequences of exposure to endocrine disrupting chemicals must end. Over recent decades, evidence has mounted showing that many pesticides interfere with hormones—and are therefore endocrine-disrupting chemicals (EDCs). In 1996, the promise of screening pesticides for endocrine disruption generated support from environmentalists and public health advocates for the Food Quality Protection Act (FQPA), which traded the absolute prohibition of carcinogens in food of the Delaney Clause for a risk assessment standard that is subject to manipulation and an underestimation of real-life hazards. And now, 25 years later, we have yet to see EPA use endocrine disruption findings in pesticide registration decisions. >>Tell EPA that pesticide use cannot continue without findings of no endocrine disruption. The endocrine system consists of a set of glands (thyroid, gonads, adrenal and pituitary) and the hormones they produce (thyroxine, estrogen, testosterone and adrenaline), which help guide the development, growth, reproduction, and behavior of animals, including humans. Hormones are signaling molecules, which travel through the bloodstream and elicit responses in other parts of the body. More than 50 pesticide active ingredients have been identified as […]

(Beyond Pesticides, April 1, 2021) A legacy of toxic pesticide use in agriculture is showing up as residues on organic farms, emphasizing the threat of a history of weak regulatory standards that has left farmland poisoned and the urgent need to transition to organic. A study, published in Environmental Science & Technology, documents the findings of pesticide residues on organic farmland and shows a decrease in residues after transition, with lingering effects for decades.  Some banned pesticides like organochlorines (e.g., DDT and chlordecone) are stable as research demonstrates these chemicals can bind to and linger in the dirt for years to decades. However, other current-use pesticides also pose a soil contamination risk due to drift, runoff, and leaching.  Widespread, increasing pesticide use in genetically engineered crops has implications for contamination of natural resources, including soils. Since pesticide residues can kill off beneficial soil life, impacting soil health and function, agricultural production may decline. Past studies examining pesticide residues rarely investigate residue’s presence in the soil where the chemical has never been used, like organic systems. Therefore, studies like these highlight the need to examine the effect potential pesticide contamination has on soil health, especially in organic where reliance on biological soil […]

(Beyond Pesticides, March 25, 2021) A new University of California San Francisco (UCSF) study, published in Environmental Science & Technology, finds over 100 chemicals present in U.S. pregnant women’s blood and umbilical cord samples. This discovery ignites concerns over prenatal exposure to chemicals from consumer and industrial products and sources. Furthermore, 89 percent of these chemical contaminants are unknown sources and uses, lacking adequate information, or are not previously detectable in humans. The National Health and Nutrition Examination Survey (NHANES) finds U.S. pregnant women experience frequent exposure to environmental pollutants that pose serious health risks to both mother and newborn. Many known environmental 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.  Current chemical biomonitoring methods only analyze a targeted few hundred chemicals—a small portion of the over 8000 chemicals the U.S. manufactures and imports. However, this study employs new technology that identifies a more comprehensive range of industrial chemicals. Therefore, research like this is essential for future technological development that can identify likely omnipresent chemical exposures for future health risks. UCSF scientists […]

(Beyond Pesticides, February 11, 2021) California sea lions (Zalophus californianus) are experiencing high rates of urogenital carcinoma (UGC) cancer incidences from the combined effect of toxic “legacy” pesticides like DDT and the viral infection Otarine herpesvirus-1 (OtHV1), according to a new study published in Frontiers in Marine Science. Previous research documents the role herpesvirus infection, genotype, and organochlorine pesticides play in sea lion cancer development. However, synergism (collaboration) between viral infection and toxic chemical exposure increases cancer development odds. Pollution of the oceans with toxic chemicals lacks adequate regulation, is widespread and only getting worse. More than 80 percent of ocean pollution comes from land-based, anthropological activities. A recent study published in Annals of Public Health finds toxic chemicals from pesticides, heavy metals, plastics, and other sources readily contaminate the ocean, especially near coastal regions where chemical inputs occur in higher concentrations. Globally, pollution has major disease implications, causing the deaths of over nine million people annually. Therefore, it is essential to understand the co-effects of ocean pollution and diseases to protect human health. Authors of the study state, “This study has implications for human health, as virally associated cancer occurs in humans, and likelihood of cancer development could similarly be increased by exposure to environmental […]

(Beyond Pesticides, January 28, 2021) Persistent organic pollutants (POPs)—including banned pesticides—present a health risk to the endangered Qinling Panda (Ailuropoda melanoleuca qinlingensis), the rarest subspecies of giant pandas, according to a new Chinese study published in Environmental Pollution. Organochlorine compounds (OCs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are well-known persistent organic pollutants. They were banned by the Stockholm Convention treaty in 2001 and are primary pollutants of concern (UNEP, 2009) 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. The U.S. was a signatory to the treaty, but U.S. Senate never ratified it, relegating U.S. officials to observer status. Although various studies demonstrate the volatile, toxic nature of POPs, much less research evaluates the impact POPs have on biodiversity over time. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one million species of plants and animals at risk. With the increasing rate of biodiversity loss, advocates say it is essential for government agencies to research how previous and ongoing use of POPs can impact present-day species. Likewise, collaborative, […]

(Beyond Pesticide, January 14, 2021) Long-term exposure to permethrin and legacy organochlorine pesticides (aldrin, dieldrin, and lindane) increase the risk of developing monoclonal gammopathy of undetermined significance (MGUS), a blood disease that likely precedes multiple myeloma (MM)—a type of blood cancer, according to research in the journal Environmental Health Perspectives. Globally, cancer is one of the leading causes of death, with over eight million people succumbing to the disease every year. Notably, the International Agency for Cancer Research (IARC) predicts new cancer cases to rise by 67.4% in 2030. Although there is a vast amalgamation of research linking cancer risk to genetic and external factors (e.g., cigarette smoke), there is increasing evidence that pesticide exposure augments the risk of developing both common and rare cancers, including MM. This study highlights the importance of understanding how pesticide use can increase the risk of latent diseases, which do not readily develop upon initial exposure. Study researchers state, “Our findings provide important insights regarding exposures to specific pesticides that may contribute to the excess of MM among farmers… [T]he continued widespread residential and other use of permethrin and environmental exposure to organochlorine insecticides due to legacy contamination…could have important public health implications for exposed individuals in the general population.” […]

(Beyond Pesticides, October 15, 2020) A review of scientific literature on the correlation between respiratory diseases and pesticides exposure—published in the journal Annals of Agricultural and Environmental Medicine (AAEM), “Influence of pesticides on respiratory pathology—a literature review”—finds that exposure to pesticides increases incidents of respiratory pathologies (i.e., asthma, lung cancer, and chronic obstructive pulmonary disease [COPD]—or chronic bronchitis). The review by researchers at the Iuliu Hatieganu’ University of Medicine and Pharmacy Cluj-Napoca, Cluj-Napoca, Romania, looks at how pesticide exposure adversely propagates and reinforces respiratory diseases in humans. This review highlights the significance of evaluating how pesticide exposure impacts respiratory function, especially since contact with pesticides can happen at any point in the production, transportation preparation, or application treatment process. Researchers in the study note, “Knowing and recognizing these respiratory health problems of farmers and their families, and also of [pesticide] manipulators/retailers, are essential for early diagnosis, appropriate treatment, and preventive measures.” This study results are critically important at a time when exposure to respiratory toxicants increases vulnerability to Covid-19, which attacks the respiratory system, among other organic systems. The respiratory system is essential to human survival, regulating gas exchange (oxygen-carbon dioxide) in the body to balance acid and base tissue cells for normal […]

(Beyond Pesticides, August 20, 2020) Persistent organic pollutants (POPs), including banned and current-use pesticides are present in snow and ice on top of Arctic glaciers, according to the study, “Atmospheric Deposition of Organochlorine Pesticides and Industrial Compounds to Seasonal Surface Snow at Four Glacier Sites on Svalbard, 2013–2014,” published in Environmental Science & Technology. Past research finds that air contaminated with these environmentally bioaccumulative, toxic chemicals drift toward 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 become significant, as glaciers encapsulating these toxic chemicals are melting. Upon melting, some chemicals can volatize back into the atmosphere releasing toxicants into air and aquatic systems, with the ensuing consequences. Although this research demonstrates that specific computer programs can track the trajectory of chemically contaminated air parcels with practical precision, it falls to global leaders to curtail the continued manufacturing of these chemical pollutants. [For related pieces, see Silent Snow: The unimaginable impact of toxic chemical use and DDT in Glacial Melt Puts Alaskan Communities at Risk.] Countless scientists consider Arctic environments to be “pristine,” void of direct chemical inputs from pesticides and other POPs. However, the Arctic has become a sink for […]

(Beyond Pesticides, July 30, 2020) Simultaneous exposure to pesticides and noise from agricultural machinery increases farmworkers, risk of hearing loss, according to the study, “Hearing Loss in Agricultural Workers Exposed to Pesticides and Noise,” published in the journal Annals of Work Exposures and Health. Hearing loss is the 3rd most common health issue in the U.S., affecting eight million Americans. Although specific conditions like age, illness, and genetics, can mediate hearing loss, research suggests other factors can induce auricle (ear) damage, including medications, exposure to toxic chemicals (including pesticides), and loud, ongoing noise. Past studies find an association between hearing loss and pesticide exposure or noise exposure, alone. However, this study is one of the first to associate hearing loss with the additive effect to concurrent, persistent pesticide exposure, and noise. This research is significant as human senses are integral to everyday human activities, and it is vital to understand how chronic pesticide exposure can limit the body’s ability to function normally, for farmers and everyone alike. Researchers in the study note, “[I]t is necessary to understand what work-related factors are contributing to this high prevalence of hearing loss in [Thai] agricultural workers in order to develop effective interventions and […]

(Beyond Pesticides, July 23, 2020) Chronic pesticide use, and subsequent exposure, elevate a person’s risk of developing lung cancer, according to a study published in F1000Research by researchers at the Nakhon Sawan Provincial Public Health Office and Naresuan University, Thailand. Globally, cancer is one of the leading causes of death, with over 8 million people succumbing to the disease every year. Notably, the International Agency for Cancer Research (IARC) predicts new cancer cases to rise 67.4% by 2030. Although there is a vast amalgamation of research linking cancer risk to genetic and external factors (i.e., cigarette smoke), there is increasing evidence that pesticide exposure augments the risk of developing lung cancer, as well. This study highlights the importance of understanding how pesticide use can increase the risk of latent diseases, which do not readily develop upon initial exposure.  Study researchers state, “To our knowledge, the association between lung cancer and pesticides has never been studied before among [Thai] people. The objective of this study was to investigate associations between pesticide exposure and lung cancer among people [living in Nakhon Sawan province, Thailand]. The results can be used for the prevention of lung cancer, and to support the global literature.” Lung cancer is one of the […]

(Beyond Pesticides, July 10, 2020) A study published in June 2020 in Environmental Health journal is especially concerning for people who become, or plan to become, pregnant. It concludes that personal, agricultural, and household exposures to pesticides may increase the risk of a relatively rare fetal disorder called “holoprosencephaly.” The study finds that pre-conception and the first few weeks of pregnancy are the most vulnerable periods during which exposure can increase risk of this disorder, in which the embryo’s forebrain fails to develop into two distinct hemispheres. The study’s results reinforce Beyond Pesticide’s long-standing warnings of the dangers of pesticides to children and the necessity of shifting to a precautionary approach to the introduction and use of synthetic pesticides (and other chemicals) across all sectors. The importance of this shift is perhaps no more poignantly illustrated than in the impacts that pesticide exposure can have on new life. The study, conducted from 2016 through 2019 by researchers from NIH (the U.S. National Institutes of Health) and the University of Wisconsin–Madison, is a case-control study — one that compares subjects who have a disease or disorder with “controls” who do not have the disorder, comparing the frequency of exposure to a particular risk […]

(Beyond Pesticides, June 18, 2020) Residential exposure to household pesticide products increases the risk of developing symptoms associated with depression, according to a study published in Environmental Research by researchers at Medical College of Georgia—Augusta University, School of Medicine—Jinan University, and Guangzhou Center for Disease Control and Prevention (CDC), China. Research on pesticide-induced diseases commonly investigates pesticide exposure concerning the development of various physical illnesses, and previous studies show there are occupational risks of developing depression, especially in agriculture where pesticide use is rampant. However, 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. This research highlights the significance of researching potential mental health effects resulting from pesticide exposure, especially as society tends to rank mental health risks second to physical health. The study’s scientists note, “Our results highlight the importance of the cautious use of household pesticides because the chronic effects of poisoning may contribute to an elevated risk of depression.”  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 2015. Although the etiology of depression—and […]

(Beyond Pesticides, May 28, 2020) Exposure to agricultural and industrial pesticides, solvents (thinners), electromagnetic fields, and heavy metals predispose humans to amyotrophic lateral sclerosis (ALS), according to an Italian research study, “Environmental and Occupational Risk Factors of Amyotrophic Lateral Sclerosis: A Population-Based Case-Control Study,” published in the International Journal of Environmental Research and Public Health. Although research supports ALS’s genetic etiology, epidemiologic research associating ALS risks and to environmental, or work-related risk factors (i.e., pesticide use, pollutant exposure, heavy metal exposure, etc.) has been inconsistent and non-definitive. This research demonstrates the importance of assessing aggregate health risks associated with occupational pesticide exposure, especially when determining potential exposure routes in specific occupational sectors. In the study, researchers note, “In particular, having an occupation in the agricultural sector, especially with a long duration of the working activity as well as occupational exposure to some chemicals…might increase ALS risk.” While scientists extensively study the epidemiology of amyotrophic lateral sclerosis (ALS)—a rare, yet fatal neurodegenerative disease—occupational and environmental hazards inducing random (sporadic) or hereditary ALS diagnoses remain vague. With researchers predicting a global ALS incidence increase of 69% by 2040, identifying ALS’s causal factors are important to future research. In this research, Italian researchers conducted a case-control, […]

(Beyond Pesticides, May 14, 2020) Four banned organochlorine pesticides (OCP) are present in over 60% of a cohort of reproductive-age, black women in Detroit, according to a study published in Environmental Research by Boston University School of Public Health (BUSPH). OCPs are lipophilic (fat combining/dissolving), environmentally steadfast chemicals linked to harmful health effects. This study stresses the importance of monitoring pesticide accumulation, particularly regarding environmentally persistent chemicals and their metabolization via indirect exposure routes. Lead author Olivia Orta, Ph.D., a postdoctoral research associate in the Department of Epidemiology at BUSPH, highlights the significance of water monitoring—especially in light of historically disproportionately high hazards for people of color (e.g., Flint, Michigan)—and testing sources prone to OCP contamination. She remarks, “The sources that we identified as potential OCP correlates should be tested for pesticide contamination,[…] especially drinking water.” Environmental contaminants, like organochlorine pesticides (OCP), can persist in the environment decades after use stops, as OCPs have greater chemical stability and gradual attenuation. Minority populations are at higher exposure risk of environmental contaminants (i.e., pesticide) exposure that can catalyze adverse health and birth effects, especially in metropolitan areas. Although black women endure higher body burdens than other U.S. populations, there remains a lack of research surrounding the association. Boston University researchers enrolled […]

(Beyond Pesticides, April 15, 2020) Home pesticide use during pregnancy is associated with an increased risk of a child developing the kidney cancer nephroblastoma, or Wilms’ tumor, according to research published in Cancer Epidemiology by a team of French scientists. Wilms’ tumor is one of the most common childhood cancers but has an inscrutable etiology. This study adds weight to the theory that pesticides are a driver of the tumor’s development, as pesticide use was more strongly associated than other widely investigated causes, including parental smoking and alcohol consumption during pregnancy. Families enrolled in an ongoing nationwide French study were questioned by phone about their lifestyle, including smoking habits, mother’s alcohol consumption, and household pesticide use. Participants were further segmented by their frequency of these risk factors, and pesticide use was narrowed down by type, including herbicide, fungicide, and insecticide use, as well as where the chemicals were used (indoor/outdoor). Researchers ultimately enrolled 117 families whose children developed nephroblastoma, and included 1100 families as a control. A regression analysis found no association between either parent smoking and incidence of the disease. Similarly, no pattern was found in the relation between maternal alcohol consumption and Wilms’ tumor. However, use of any […]

(Beyond Pesticides, February 27, 2020) A new report finds that as birds and pollinators continue to decline, and chronic diseases remain on the rise, the global agrichemical industry is raking in billions of dollars from hazardous pesticides that contribute to these crises. A joint investigation from Unearthed and Public Eye finds that 35% of pesticide sales from the largest agrichemical corporations are made from the most toxic pesticides on the market. Pesticide production was a $57.6 billion market in 2018, according to the report. While the profits of the industry are privatized, the public health and environmental effects are broad. Studies conducted over the last decade show that the impacts of hazardous pesticide use dwarf the market for these chemicals. The impact of pesticides on public health results in a drag on the economy. Earlier this year, research from the New York University Grossman School of Medicine found that children’s exposure to organophosphate insecticides was estimated to result in over 26 million lost IQ points and over 110,000 cases of intellectual disability, totaling roughly $735 billion in economic costs each year. A 2019 study from the same scientists determined that endocrine disrupting chemicals, including organophosphates and organochlorine pesticides, were attributable […]

(Beyond Pesticides, December 17, 2019) South Asian immigrants to the U.S. may be at increased risk of diabetes due to prior exposure to high levels of DDT, research published by the University of California Davis earlier this month indicates. The study highlights a blind spot for health care in the U.S., researchers say. “Our findings evoke a new interpretation of Rachel Carson’s famous book Silent Spring, in that the high DDT exposures of South Asian immigrants in the U.S. currently fall on deaf ears in the U.S.,” said lead author Michele La Merrill, PhD an associate professor in the UC Davis Department of Environmental Toxicology. “Although DDT remains in use in other nations and migration globalizes these exposures, people in the U.S. often mistakenly regard DDT exposure as no longer relevant to our society due to its ban in this country nearly 50 years ago.” When compared to other race and ethnic groups, South Asian immigrants (individuals from India, Pakistan, Bangladesh, Nepal, Sri Lanka, and Bhutan), are at greater risk of developing diabetes, even when adjusting for potential confounders such as age and obesity. Authors of the study hypothesized that this was a result of past exposure to high levels […]
