Exposure to Pesticides in the Womb Increases Risk Associated with Rare Eye Cancer Among Children

(Beyond Pesticides, September 29, 2022) A study published in the International Journal of Hygiene and Environmental Health finds an association between retinoblastoma risk and prenatal exposure to pesticides. Retinoblastoma is a rare eye cancer, with over 200,000 cases in the U.S., most of which are children under the age of five. Despite occurring among offspring, this cancer is often not hereditary. Instead, a mutation in the RB1 gene during early development in the womb destabilizes and augments cell growth. Although the etiology or cause of childhood eye cancer involves the interaction of multiple components like lifestyle and genetics, emerging evidence indicates that environmental contaminants like pesticides (e.g., occupational exposures, air pollution, pesticides, solvents, diet, etc.) play a role in disease etiology. Pesticide contamination is widespread in all ecosystems, and chemical compounds can accumulate in human tissues resulting in chronic health effects. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Already, studies find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects from metabolic disorders to mental and physical disabilities. While medical advancements in disease survival are more prominent nowadays, childhood cancer remains the leading cause of death from disease among children. […]

Beyond Pesticides Calls on Administrators to Keep Pesticides Out of Schools, Children at Elevated Risk

(Beyond Pesticides, September 19, 2022) Schools have been deeply concerned about providing safety from COVID-19, but often overlook that the toxic pesticides to which students, teachers, and other staff may be exposed in going back to school threaten their health, both short- and long-term. Beyond Pesticides identifies the health hazards that pesticides pose to the nervous, immune, and respiratory systems, as well as brain function, and their association with cancer and other chronic effects. At the same time, practical, and cost-effective pest management practices are available that do not utilize toxic pesticides (including disinfectants). Tell your Governor to ensure that children, teachers, and staff in all schools throughout your state are protected from toxic chemicals. Children face unique hazards from pesticide exposure. In the food they eat and the air they breathe, children take in greater amounts of pesticides (relative to their body weight) than adults, and their developing organ systems are typically more sensitive to toxic exposures. Children also come into closer contact with chemicals than adults, as a result of crawling behavior and hand to mouth contact. The American Academy of Pediatrics, in a landmark report on children and pesticide use, wrote, “Children encounter pesticides daily and have […]

Compounds in Pesticides Shown to Harm Fetuses and Children with Disproportionate Risk to People of Color

(Beyond Pesticides, September 2, 2022) Revelations of toxic risks to pregnant people seem to emerge with alarming frequency. In late August a peer-reviewed study published in Chemosphere finds that the compound melamine, its primary byproduct (cyanuric acid), and four aromatic amines were detected in the urine of nearly all pregnant research participants. These chemicals are associated with increased risks of cancer, kidney toxicity, and/or developmental harm to the resultant child. Beyond Pesticides has covered a variety of pregnancy risks from pesticides and other toxic chemicals, including these in just the last three years: pesticides and children’s sleep disorders; prenatal exposures to a multitude of chemicals; insecticides and childhood leukemia; insecticides and Attention Deficit/Hyperactivity Disorder. Those of a certain age may hear “Melamine” and think of the nearly indestructible plastic dinnerware from the mid-20th century, but “melamine” is an organic chemical compound that, when combined with formaldehyde, forms a durable plastic. Others may remember the 2007–2008 incident in China of contamination of infant formula with melamine, which resulted in six deaths, and kidney and urinary tract harms (ranging from development of kidney stones to acute renal failure) in some 300,000 babies. [A small sidebar explainer: melamine was actually intentionally added to the formula […]

Exposure to Synthetic Pyrethroids During Infancy Associated with Developmental Delays in Toddlers

(Beyond Pesticides, September 1, 2022) Low level exposure to synthetic pyrethroid insecticides at 6-8 months of age is associated with language development delays in two-year old toddlers, according to research published in Neurotoxicology this month. This is the latest study to link this class of chemicals to developmental delays in young children. Despite a steady drum of concerning research, the U.S. Environmental Protection Agency (EPA) in 2019 removed a crucial “safety factor” intended to protect children’s health from synthetic pyrethroids, allowing higher levels of the insecticides to be sprayed on food, in homes, and playing fields around the country.   To investigate the impact of synthetic pyrethroids on language development, scientists enrolled 327 expectant mothers in their third trimester. The mothers, all from rural areas of China, were selected if they had no history of significant pesticide exposure or family history of serious disease. Urine samples were taken from the women during pregnancy, and from infants 6-8 months after birth. Scientists analyzed samples for concentrations of three different synthetic pyrethroid breakdown products (metabolites), including 3-phenoxybenzoic acid (3PBA), 4-fluoro-3-phenoxybenzoic acid (4F3PBA), and cis-2,2dibromovinyl-2,2-dimethylcyclopropane-1-carboxylic acid (DBCA). While 3PBA is a metabolite of many synthetic pyrethroids, 4F3PBA a more specific metabolite of cypermethrin, […]

Antibiotics and Neonicotinoid Insecticides Linked to Gut Microbiome Disruption and Childhood Diabetes

(Beyond Pesticides, August 25, 2022) A study published in World Journal of Pediatrics finds an association between antibiotic and neonicotinoid (neonic) exposure and onset of pediatric (childhood) type 1 diabetes (T1D) through effects on the gut microbiome. Individuals with type 1 diabetes are at higher risk of other autoimmune disorders, including thyroid and celiac disease. Ample evidence demonstrates environmental contaminants like pesticides and antibiotics negatively affect human mouth and gut microbes. Through the gut biome, pesticide exposure can enhance or exacerbate the adverse effects of additional environmental toxicants on the body. Moreover, studies find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects from metabolic/immune disorders to mental and physical disabilities. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Although studies show how chemical exposures affect overall human health, more research is now questioning how these toxic chemicals influence gut health and subsequent occurrence of diseases. In children, gut microbiome disruption, or gut dysbiosis, has significant associations with type 1 diabetes development, and disruption of gut microbiota plays a role in type 2 diabetes development. Over 11 percent (>37 million) of individuals in the U.S. have diabetes, and cases are growing by millions annually. With increasing rates of type 1 and […]

Parents’ Exposure to Pesticides Indicative of Childhood Cancer Risk among Offspring

(Beyond Pesticides, August 18, 2022) A study published in Environmental Research suggests occupational (work-related) exposure to pesticides among nonpregnant women and men may increase childhood cancer risk for offspring. Already, studies find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects from metabolic disorders to mental and physical disabilities. However, few assess parental exposure’s impact on childhood disease risk outside critical development periods (e.g., pregnancy). Although medical advancements in disease survival are more prominent nowadays, childhood cancer remains the leading cause of death from disease among children. Furthermore, childhood cancer survivors can suffer from chronic or long-term health complications that may be life-threatening. The etiology or cause of childhood cancer involves the interaction of multiple components like lifestyle and genetics. However, emerging evidence indicates that environmental contaminants like pesticides (e.g., occupational exposures, air pollution, pesticides, solvents, diet, etc.) play a role in disease etiology. Pesticide contamination is widespread in all ecosystems, and chemical compounds can accumulate in human tissues resulting in chronic health effects.

Pesticides Linked to Adult and Childhood Cancer in Western U.S., with Incidence Varying by County

(Beyond Pesticides, June 28, 2022) There is a strong connection between pesticide use and cancer rates in the Western United States, finds research recently published by scientists at University of Idaho and Northern Arizona University. Two studies (here and here) published in the peer-reviewed journal GeoHealth used geospatial data and publicly available pesticide databases to uncover the relationship between chemical heavy agricultural practices and cancer in both adults and children. As the rate of chronic diseases like cancer continue to increase in the United States, and more and more studies find these diseases to be pesticide-induced, it is imperative for the public to put increased pressure on regulators and lawmakers to enact meaningful measures that eliminate pesticide use and the hazards these chemicals pose. Of the two studies conducted by the research team, the first study modeled the connection between pesticide use and cancer incidence for adults and children in 11 western states (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming), while the second study focuses on childhood cancer rates in Idaho’s 44 counties. Both studies utilized databases established by public entities, including U.S. Geological Survey (USGS) Pesticide National Synthesis Project database, EPA Pesticide Industry […]

Study Finds Chemical Exposure Increasing among Pregnant Women

(Beyond Pesticides, May 11, 2022) Pregnant women are being exposed to increasing amounts of dangerous industrial chemicals, according to research published this week in Environmental Science and Technology.  The chemicals in question include pesticides, plastics, and parabens, as well as ‘replacement chemicals’ for substances like phthalates and bisphenols that have gained notoriety for risks to public health. With a range of scientific data highlighting chemical exposures during pregnancy as a critical window of vulnerability, public awareness of these growing threats, and meaningful action by government regulators to reduce exposure is needed.   The results of this study follow the release of data last year finding over 100 different chemicals in U.S. pregnant women’s blood and umbilical cord samples. For the present study, however, researchers did not merely detect these chemicals, they tracked exposure levels over the course of 12 years. The cohort of 171 women represents a diverse group from seven American states and territories (including New Hampshire, New York, Puerto Rico, Illinois, California, and Georgia), with 20% of women participating Black, one third white, 40% Latina, and the remaining from other or multiple groups. Over the course of the study, routine monitoring was conducted utilizing an advanced diagnostic method […]

Glyphosate Breakdown Product, Associated with Oxidative Stress and DNA Damage Among Children

(Beyond Pesticides, April 28, 2022) A study in Environmental Research finds that glyphosate’s primary metabolite (breakdown product), aminomethylphosphonic acid (AMPA), induces DNA damage through oxidative stress among subpopulations of primary school children. Although pyrethroid and chlorpyrifos metabolites can induce oxidative stress, this study is the first to investigate AMPA’s association with adverse health effects, rather than solely the effects of the active ingredient, glyphosate, in Roundup and other formulations. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulations, readily contaminating soil, water, food, and other resources. Chemical use has been increasing since the inception of crops genetically modified to tolerate glyphosate. However, studies demonstrate glyphosate is among the most prevalent pesticide contributors to human, biotic, and ecosystem harm. According to research, herbicide toxicity to invertebrates has doubled since 2004. Although research links glyphosate exposure to cancer, specifically non-Hodgkin lymphoma, much less research considers the effects that metabolites have on children who are more vulnerable to chemical exposure. Ecological and health risk assessments primarily focus on active ingredients in pesticide products, overlooking the potential impacts of metabolites. Thus, studies like these highlight the need to assess the implications of metabolite exposure to protect human, animal, and environmental health. The study notes, “Our […]

Minnesota Biomonitoring Study Addresses Children’s Exposure to Pesticides, Air Pollutants, and Toxic Metals

(Beyond Pesticides, March 9, 2022) In response to local concerns around children’s environmental exposures, the Minnesota Department of Health (MDH) recently published biomonitoring data collected from young children living in urban and rural areas of the state. The findings provide local residents and lawmakers with baseline data on the hazards children are encountering where they live, learn, or play, and point to ways in which families can reduce or eliminate these dangers. With evidence that early life exposures during “critical windows of vulnerability” increase risk of long-term health problems, it is critical for state agencies to both collect data, and take meaningful action to protect children from future harms. Minnesota lawmakers established a state biomonitoring program in 2007, and have since expanded the project. The current report represents the results of MDH’s Healthy Rural and Urban Kids Project aimed at biomonitoring chemicals in young children. For this round, the agency focused on preschool-aged children living in MN’s rural Becker, Todd, and Wadena counties, as well as those living in urban North Minneapolis. MDH enrolled 232 families during the summer of 2018, provided them with a questionnaire, and tested children for 21 different chemicals in their urine. The chemicals tested were […]

Pesticide Use During Pregnancy Increases Childhood Risk of Ear Infections

(Beyond Pesticides, February 9, 2022) Insecticide use during pregnancy significantly increases the occurrence of Otitis Media (OM) in infants, according to research published in Scientific Reports from a team of Japanese researchers late last month. Otitis Media, an infection of the space behind the ear drum, is a common disease among children. While most infections go away on their own, some children experience pain, fever, and in some cases complications that result in hearing loss. This research underscores the myriad of dangers and diseases that pesticide use can precipitate, which are not considered under risk assessments conducted by the U.S. Environmental Protection Agency (EPA). Scientists collected their initial data from the ongoing Japan Environment and Children’s Study, a national birth cohort study that evaluates environmental factors affecting children’s health in Japan. Data recorded include factors such as maternal age, birth weight, and gestation weeks, and mothers provided answers to a range of questionnaires, including one relating to exposure to insecticides during pregnancy. Study authors utilized a range of other covariates to control for further risk factors, such as family history of OM, living with other siblings, nursery attendance, parental smoking habits, and others. The study determined that OM during an […]

Household Pesticide Use Harms Infant Motor Skill Development

(Beyond Pesticides, January 5, 2022) Household pesticide use is associated with harmful impacts to infant motor development, according to a study published late last year in the journal Paediatric and Perinatal Epidemiology. The research focused on primarily low-income Hispanic women located in Los Angeles, California, enrolled in an ongoing study referred to as Maternal and Developmental Risks from Environmental and Social Stressors (MADRES). As with other pollutants in society, low-income, people of color communities are disproportionately in contact with toxic pesticides, resulting in exposures that can start early, and affect health over the course of one’s lifetime. Women enrolled in the MADRES cohort are over the age of 18, and speak English or Spanish fluently. For the present study, roughly 300 MADRES participants met the criteria for enrollment, and completed household pesticide use questionnaires at a 3-month post-natal visit. The questionnaire generally inquired whether pesticides had been used in one’s home since their child was born. After another 3 months, researchers also tested infants’ motor development using an Ages and Stages-3 protocol screening tool, which evaluates a child’s ability to execute muscle movements. Overall, roughly 22% of mothers reported pesticide use in their home during the first months of their […]

Pesticide Exposure Contributes to Preterm Births and Low Birth Weight

(Beyond Pesticides, November 18, 2021) A study published by King George’s Medical University, India, finds exposure to xenobiotic substances like pesticides during pregnancy increases risks associated with preterm birth, including a rise in cesarean section (C-section) deliveries and a decrease in fetal body weight. Preterm births occur when a fetus is born early or before 37 weeks of complete gestation. Premature births can result in chronic (long-term) illnesses among infants from lack of proper organ development and even death. Birth and reproductive complications are increasingly common among individuals exposed to environmental toxicants, like pesticides. The Center for Disease Control (CDC) reports the preterm birth rate is increasing annually. Therefore, studies like this can help government and health officials safeguard human health by assessing adverse effects following prevalent chemical exposure. The study notes, “To the best of our knowledge, this was a pioneering study, and it may help to increase our knowledge with regard to xenobiotic exposure in biological systems and the need for stringent guidelines for agricultural use of pesticides.” The study examines the association between the transfer of xenobiotics (foreign synthetic substances like pesticides) from mother to fetus. Transferal of these toxic substances can result in biological and chemical changes (i.e., genotoxicity […]

Call on USDA to Provide Organic School Lunches to Fight Childhood Obesity

(Beyond Pesticides, November 15, 2021) A recent hearing in the U.S. Senate Agriculture Subcommittee on Food and Nutrition, Specialty Crops, Organics, and Research, subcommittee chair Senator Cory Booker stressed the failures of the U.S. Department of Agriculture’s (USDA) food and nutrition programs, saying, “Our food system is not a “free market,” we are picking winners and losers, and it’s consumers, family farmers, and food workers who are losing.” Tell USDA’s Food and Nutrition Service to require organic school lunches. Experts at the hearing pointed out impacts of poor nutrition choices that are driven by USDA’s policies. Associate professor Angela Odoms-Young, PhD of Cornell University said, “People of color overall, and Black populations specifically, face higher rates of diet-related chronic conditions and have poorer dietary intakes as compared to whites. We did not get here by chance but through policy.” Childhood obesity is a serious problem in the U.S., leading to a host of health problems in childhood and later in life. Juvenile obesity is highest in Hispanic, African American, and lower income groups, which provides an opportunity for USDA’s school lunch program to have a positive impact. At the hearing, Donald Warne, MD, MPH of the University of North Dakota medical […]

Persistent Organic Pollutants, including Banned Pesticides, Remain Present in all Fetal Organs Regardless of Maternal Chemical Contamination

(Beyond Pesticides, September 16, 2021) A study published in Chemosphere finds persistent organic pollutants (POPs), including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs), are present in the serum and placenta of pregnant mothers, as well as multiple fetal organs. Many studies indicate prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. However, this study is one of the first to demonstrate the presence of chemical toxicants in fetal tissue that are not present in maternal serum or placental samples. Prenatal development is one of the most vulnerable periods of exposure when the fetus is most susceptible to the harmful effects of chemical contaminants. Therefore, studies like these help government and health officials better identify fetal exposure contaminants and subsequent health concerns otherwise missed by current chemical monitoring methods. The researchers note, “These findings call for further evaluation of the current matrices used to estimate fetal exposure and establish a possible correction factor for a more accurate assessment of exposure in utero. We disclose the full data set on individual exposure concentrations to assist in building in silico models for prediction of human fetal exposure to chemicals.” Several studies associate early-life exposure to toxic chemicals […]

In Utero and Childhood Pesticide Exposure Increases Childhood Cancer Risk

(Beyond Pesticides, September 1, 2021) A study published in Environmental Pollution finds the risk of acute childhood leukemia (AL) increases with prenatal and newborn exposure to pesticides (i.e., insecticides and herbicides). The study results support the hypothesis that chronic environmental pesticide exposure increases childhood leukemia risk up to two times. Maternal exposure has a stronger association with leukemia than childhood exposure. Insecticides and herbicides are of particular significance in increasing leukemia risk, especially for acute lymphoblastic leukemia. Although medical advancements in disease survival are more prominent nowadays, childhood AL remains the secondary cause of child mortality following physical injury. Furthermore, childhood leukemia survivors can suffer from chronic or long-term health complications that may be life-threatening. Although the etiology or cause of childhood AL involves the interaction of multiple components like lifestyle and genetics, emerging evidence indicates that environmental contaminants like pesticides (e.g., occupational exposures, air pollution, pesticides, solvents, diet, etc.) play a role in disease etiology. Pesticide contamination is widespread in all ecosystems, and chemical compounds can accumulate in human tissues resulting in chronic health effects. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects.

Tell EPA to Ban ALL Uses of Chlorpyrifos

(Beyond Pesticides, August 30, 2021) As with other actions on pesticides, EPA’s chlorpyrifos decision is filled with exceptions that respond to vested interests seeking to ignore or deflect the science. EPA, since announcing its decision in 1999 to ban “residential” uses of chlorpyrifos, continues to allow the following uses: (i) Residential use of containerized baits; (ii) Indoor areas where children will not be exposed, including only ship holds, railroad boxcars, industrial plants, manufacturing plants, or food processing plants; (iii) Outdoor areas where children will not be exposed, including only: golf courses, road medians, Industrial plant sites; (iv) Non-structural wood treatments including: fenceposts, utility poles, railroad ties, landscape timers, logs, pallets, wooden containers, poles, posts, and processed wood products; (v) Public health uses: Fire ant mounds (drench and granular treatment); (vi) nurseries and greenhouses; and (vii) Mosquito control. These uses are unaffected by EPA’s announcement. We need to finish the chlorpyrifos job. Tell EPA to ban all uses of chlorpyrifos. The collective effort to remove this one chemical is a tremendous feat in eliminating one exposure to a hazardous material for children. Achieving the ban on food uses required an enormously resource-intensive effort at a time in history when we are […]

Exposure to Common Herbicide Glyphosate Increases Spontaneous Preterm Birth Incidents

(Beyond Pesticides, August 26, 2021) A recent study published in Environmental Research demonstrates that exposure to the herbicide glyphosate and its breakdown product reduces pregnancy length, increasing the risk of preterm birth. Preterm births occur when a fetus is born early or before 37 weeks of complete gestation. Premature births can result in chronic (long-term) illnesses among infants from lack of proper organ development and even death. Birth and reproductive complications are very common among individuals exposed to environmental toxicants, like pesticides. Considering the Center for Disease Control (CDC) reports the preterm birth rate is increasing annually, studies like this can help government and health officials safeguard human health by assessing adverse health effects following prevalent chemical exposure. The study notes, “Given the prevalent and rising exposures to glyphosate and GBHs [glyphosate-based herbicides], confirmatory studies are needed to explore reproductive effects of glyphosate and GBHs to re-assess their safety on human health and to explore possible programming consequences to lifelong health.” GBHs are the most commonly used herbicides, readily contaminating soil, water, and food globally. Although GBHs’ ubiquitous nature has been linked to carcinogenic effects, specifically non-Hodgkin lymphoma, much less research considers exposure effects on reproductive health. The study’s scientists aimed to examine the relationship […]

Insecticide Chlorpyrifos Interacts with Genes to Increase Autism Risk, Research Finds

(Beyond Pesticides, July 20, 2021) Chlorpyrifos exposure results in the expression of genetic mutations associated with autism spectrum disorder in a laboratory model, finds research published in Environmental Health Perspectives by scientists at Johns Hopkins Bloomberg School of Public Health. “This is a step forward in showing an interplay between genetics and environment and its potential role for autism spectrum disorder,” says study lead Lena Smirnova, PhD, a research associate in the Department of Environmental Health and Engineering at the Bloomberg School. The findings support reams of research already conducted that show strong associations between autism and exposure to hazardous environmental stressors like toxic pesticides. Scientists conducted their study using a ‘brain organoid’ model, which is essentially a cluster of cells artificially grown in the lab from stem cells in order to mimic a developing human brain. These tests provide certain benefits over animal testing, as they are more relevant to human disease, and can be performed faster with less cost. The organoid model also represents an improvement on typical 2d cell-based models, increasing cell survival, shelf-life, and thus providing opportunity to model for later stages of brain development. Brain organoids in this study carried a gene called CHD8, which […]

Kids Who Eat Organic Food Score Higher on Cognitive Tests, Study Finds

(Beyond Pesticides, July 7, 2021) Organic food consumption among children is associated with higher scores on tests measuring fluid intelligence and working memory, research published in the journal Environmental Pollution finds. The study, conducted by Spanish researchers based at the Barcelona Institute for Global Health, took an exposome approach to environmental exposures, looking at a totality of all environmental hazards that children encounter, rather than investigating individual lifestyle factors one by one. As study co-author Jordi JĂșlvez, PhD, notes, “healthy diets, including organic diets, are richer than fast food diets in nutrients necessary for the brain, such as fatty acids, vitamins and antioxidants, which together may enhance cognitive function in childhood.” Researchers began their study by selecting mother-child pairs enrolled in the Human Early-Life Exposome (HELIX) Project, a pan-European study with projects in multiple European countries. Nearly 1,300 healthy children aged 6-11 were included in the study, as researchers already had pregnancy data and urine samples stored on the participants. To determine other environmental exposures, home addresses were evaluated for their level of pollution and proximity to natural spaces, and children and their mothers were given tests that included a questionnaire on lifestyle factors, including parents smoking and alcohol use, […]

Stop EPA’s Racist Policies that Disproportionately Harm Farmworker Children’s Brains: Ban Chlorpyrifos

(Beyond Pesticides, May 17, 2021) The U.S. Environmental Protection Agency (EPA) has less than two months to decide whether to cancel or modify its registration of the brain-damaging organophosphate insecticide chlorpyrifos, following a decision from a federal appeals court. The ruling comes after more than a decade of delay from the federal agency tasked with protecting public health and the environment from the hazards of chemicals like chlorpyrifos. The decision now falls to the Biden Administration’s EPA Administrator Michael Regan, after the previous administration reversed a proposal to ban agricultural uses of chlorpyrifos in 2017. Most residential uses of the chemical were banned in 2000.  Tell EPA to ban chlorpyrifos and other neurotoxic pesticides. The target of action by which chlorpyrifos and many other pesticides kill is the nervous system. It is not surprising, then, that pesticides also target the nervous system in humans. They are particularly hazardous to children, who take in greater amounts of pesticides relative to their body weight than adults, and whose developing organ systems are typically more sensitive to toxic exposures. The body of evidence in the scientific literature shows that pesticide exposure can adversely affect a child’s neurological, respiratory, immune, and endocrine systems, even at […]

Grandmother’s Exposure to DDT Increases Granddaughters’ Breast Cancer and Cardiometabolic Disorder Risk

(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 […]
