(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 […]

(Beyond Pesticides, September 10, 2021) Research conducted in Thailand shows that exposures to pesticides, even at low levels, can impact the human endocrine system and distort thyroid function. The study looked specifically at interactions of genetics and environment: it investigated associations between variations in genes involved in pesticide metabolism and altered thyroid hormone concentrations in agricultural workers. This research underscores some of the complexity and difficulty of determining human vulnerability to impacts of pesticide exposures, given genetic variables. Beyond Pesticides believes that this very complexity is a cogent argument for anchoring regulation of pesticides in the Precautionary Principle. If exposure to a pesticide can cause damage to human (or environmental) health, it sometimes will do so. Thus, to protect people’s health, agriculture and other land management practices must transition from the use of synthetic pesticides to broad adoption of organic regenerative approaches that obviate the need for such chemicals. This research is part of a longitudinal study that seeks to evaluate sub-chronic impacts, on thyroid hormone levels, of repeated exposures to a variety of pesticides. The farmworkers studied in this phase comprise two groups: those working on organically managed farms (216 subjects), and those working on conventional farms that use pesticides […]

(Beyond Pesticides, September 9, 2021) A new study published in Toxicology Reports finds the same chemicals that disrupt the endocrine (hormone) system also disrupt the nervous system. Endocrine disruptors are xenobiotics (i.e., chemical substances like toxic pesticides foreign to an organism or ecosystem) present in nearly all organisms and ecosystems. The World Health Organization (WHO), European Union (EU), and endocrine disruptor expert (deceased) Theo Colborn, Ph.D., classify over 55 to 177 chemical compounds as endocrine disruptors, including various household products like detergents, disinfectants, plastics, and pesticides. Past research shows exposure to endocrine-disrupting pesticides adversely affects human health, from reproductive function to cancer development, and effects can span generations. However, this study is one of the few to evaluate associations between endocrine-disrupting chemicals and neurological function. Although the etiology (cause) of many sporadic (non-heritable) neurological diseases are unknown, scientists suggest exposure to environmental toxicants plays a role in disease development. Therefore, government and health officials have been urged to consider how exposure to endocrine-disrupting chemicals can impact bodily function and development apart from hormone disruption.   In the body, cells communicate through electrical or chemical signals transmitted within the nervous or endocrine system. Studies find exposure to endocrine-disrupting chemicals has a direct and indirect impact on hormone function and development. However, researchers investigated whether […]

(Beyond Pesticides, September 2, 2021) A McMaster University (Canada) study demonstrates exposure to the recently banned, commonly used insecticide chlorpyrifos promotes obesity development, even at low doses. Obesity generally occurs following a caloric imbalance between food intake, absorption, and energy expenditure. Although various factors can promote obesity, researchers suggest environmental toxicants like chlorpyrifos play a role in obesity development through protein/enzyme suppression. According to the Center for Disease Control, 42 percent of the U.S. population is obese and at risk for type two diabetes, cardiovascular (heart) disease, stroke, several cancers, and other critical health issues. Therefore, research like this highlights the significance of investigating how toxic chemical exposure can impact health to prevent adverse disease outcomes. Researchers note, “These studies suggest that the effects of environmental toxicants on the development of obesity may have been underestimated as all studies to date have been conducted in mice housed at RT [room temperature]. Future studies examining the mechanisms driving reductions in β-AR [beta adrenergic receptors] signaling and whether there are associations between BAT [brown adipose tissue] metabolic activity and CPF [chlorpyrifos] in humans will be important.” Several environmental pollutants have links to obesity development via the effects on gut health, endocrine (hormone) and metabolic system, […]

(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. Already, studies find low levels of pesticide exposure during […]

(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 […]

(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 […]

(Beyond Pesticides, August 16, 2021) The failure of the U.S. Environmental Protection Agency (EPA) to meet its statutory responsibility to protect people and wildlife from the dire consequences of exposure to endocrine-disrupting chemicals must end. The Office of the Inspector General (OIG) for EPA has issued a damning report on the agency’s progress in protecting the population from potentially damaging endocrine disruption impacts of exposures to synthetic chemical pesticides (and other chemicals of concern) that shows the situation to be even worse than previously reported. The OIG’s summary statement says, “Without the required testing and an effective system of internal controls, the EPA cannot make measurable progress toward complying with statutory requirements or safeguarding human health and the environment against risks from endocrine-disrupting chemicals.” As a result, according to the OIG, “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. 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 […]

(Beyond Pesticides, August 10, 2021) President Biden’s Environmental Protection Agency (EPA), under Administrator Michael Regan, is set to reapprove the highly hazardous herbicide paraquat with fewer protections than those proposed by the Trump administration. Despite strong links to Parkinson’s, and bans on the herbicide in the European Union, China, Brazil, and many other countries, EPA’s press release inexplicably states, “No direct one-to-one alternatives to paraquat are available.” The move is part of a string of actions that have pesticide reform advocates increasingly concerned that the Biden Administration is not living up to his initial promises to improve health and environmental protections. Paraquat is the most toxic herbicide still on the market. As EPA readily admits, one small sip of paraquat can be fatal. Apart from its acute toxicity, chronic exposure to the herbicide is strongly linked to the development of Parkinson’s disease. But its association with Parkinson’s is merely the most well-known health concern – the chemical is a likely carcinogen, harms the reproductive system, and damages organs like the kidney and liver. It is hazardous to birds and bees, and prone to leaching into groundwater, where it disrupts the health of aquatic ecosystems. The Trump administration’s decision to reapprove […]

(Beyond Pesticides, July 30, 2021) Bayer (Monsanto), the maker of the deadly herbicide glyphosate/Roundup, after hinting in May that it would end the weed killer’s residential uses in the U.S., made it official yesterday. With its announcement to shareholders, Bayer puts an end to residential uses beginning in 2023 and allocates $4.5 billion to cover “the company’s potential long-term exposure” from lawsuits by those harmed by the chemical. At the same time, the company announced it is seeking a U.S. Supreme Court hearing to reverse significant jury verdicts (from $289 million to $2 billion) for individuals who have suffered health damage they tie to glyphosate exposure. Bayer claims that it will argue that federal pesticide law preempts litigation against products that it has registered with the U.S. Environmental Protection (EPA). Similar arguments have been tried before, most notably in Bates v. Dow Agrosciences (2005), and the Supreme Court has found that federal pesticide law does not protect “manufacturers of poisonous substances.” (See more below.) Despite the extensive scientific review (see Pesticide Gateway) of glyphosate/Roundup and a “probable” cancer causing ranking by the World Health Organization/International Agency for Research on Cancer in 2015, Bayer says, “This move is being made exclusively […]

(Beyond Pesticides, July 29, 2021) New research published in Environmental Health Perspectives finds nearly 300 different chemicals in pesticides, consumer products, and contaminated resources (i.e., food, water) increase breast cancer risks. Breast cancer is the most common cancer among women, causing the second most cancer-related deaths in the United States. Past studies suggest genetic inheritance factors influence breast cancer occurrence. However, genetic factors only play a minor role in breast cancer incidences, while exposure to external environmental factors (i.e., chemical exposure) may play a more notable role. There are grave concerns over exposure to endocrine (hormone) disrupting chemicals and pollutants that produce adverse health effects. Most types of breast cancers are hormonally responsive and thus dependent on the synthesis of either estrogen or progesterone. Hormones generated by the endocrine system greatly influence breast cancer incidents among humans. Several studies and reports, including U.S. Environmental Protection Agency (EPA) data, identify hundreds of chemicals as influential factors associated with breast cancer risk. Therefore, advocates point to the need for national policies to reassess hazards associated with disease development and diagnosis upon exposure to chemical pollutants. The study’s researchers note, “This study shows that a number of chemicals currently in use have the ability to manipulate hormones known to adversely […]

(Beyond Pesticides, July 22, 2021) A new study published in the Journal of Medical Entomology finds black-legged ticks (Ixodes scapulari) in New York are developing potential resistance to widely used tick-control pyrethroid insecticide, permethrin. The study suggests continuous use of area-wide, 4-poster devices (devices that attract deer and then apply pesticide to their head, ears, and neck) to apply insecticide treatments on deer to control tick populations promotes resistance. Resistance is an ever-present issue among chemical compounds (i.e., antibiotics, antimicrobials, pesticides) used in medicine and agriculture, and threatening the ability to prevent disease outbreaks, such as Lyme disease. Furthermore, increasing populations of rodent and mammalian hosts, in addition to warmer temperatures prompted by the climate crisis, allows for disease-carrying ticks to flourish. Lyme disease is the most common vector disease and a primary concern for the general population. Therefore, studies like this highlight the need to assess resistance among disease-vector pest populations regardless of pesticide application methods. The researchers note, “Permethrin susceptibility of tick populations should be monitored from other 4-poster control areas so that guidelines for managing pesticide resistance in the field can be developed.” Four-poster devices impart selective pressure on tick populations influencing reproduction and natural extinction of species. However, like mosquitoes, a subpopulation of ticks […]

(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 […]

(Beyond Pesticides, July 14, 2021) Corteva (formerly DowDupont) is facing a potential class-action lawsuit after several California families filed suit claiming that the use of the insecticide chlorpyrifos around their homes resulted in birth defects, brain damage, and developmental problems in their children. Chlorpyrifos is an organophosphate insecticide that has been linked to a range of health ailments, posing significant hazards particularly for pregnant mothers and their children. The lawsuits come as the U.S. Environmental Protection Agency (EPA) approaches a court-imposed 60-day deadline to decide the fate of the pesticide’s registration. Attorneys for the court cases, filed on behalf of individuals located in four California communities (Fresno, Kings, Medera, and Tulare counties), indicate they intend to pursue class-action status, which would allow additional injured parties to join the lawsuit. The plaintiffs argue that the effects of chlorpyrifos exposure lingers in the agricultural communities where they reside. “We have found it in the houses, we have found it in carpet, in upholstered furniture, we found it in a teddy bear, and we found it on the walls and surfaces,” said Stuart Calwell, lead attorney for the plantiffs. “Then a little child picks up a teddy bear and holds on to it.” […]

(Beyond Pesticides, June 30, 2021) Vineyard farmers who spend more money on pesticide use are more likely to develop Parkinson’s disease, according to research published by French scientists in the journal Environmental Research. With Parkinson’s disease on the rise around the world, and emerging evidence growing for a Parkinson’s pandemic, it is critically important to suss out the factors at play. And as pesticides continue to appear as a driving force for this deadly chronic disease, it is increasingly necessary to pressure regulators to restrict use of these hazardous substances in chemical farming operations. Researchers used a French National Health Insurance Database to identify incidents of Parkinson’s disease in farmers from 2010-2015. These data were then matched with pesticide expenditures recorded from over 3,500 French farming regions, taken around the year 2000. Models were adjusted for a range of health factors, including smoking, age, and sex. Results show that accounts of Parkinson’s disease increase as pesticide expenditures increase for farmers working in vineyards. For the highest amounts paid for pesticides, Parkinson’s disease incidence is 16% higher. No connections were found for other cropping systems. “This result suggests that agricultural practices and pesticides used in these vineyards may play a role […]

(Beyond Pesticides, June 29, 2021) Maine Governor Janet Mills (D) last week vetoed legislation prohibiting the aerial use of glyphosate and other dangerous herbicides in forestry practices. LD125, An Act To Prohibit the Aerial Spraying of Glyphosate and Other Synthetic Herbicides for the Purpose of Silviculture, was supported by a wide range of health and conservation groups, and aimed to bring the state in line with best practices for public health and the environment. With Maine recently passing one of the strongest consumer bans on pollinator-toxic neonicotinoids, advocates are dismayed by the setback from the Governor’s office. In a statement to Maine Public Radio, Senate President Troy Jackson said that Governor Mills should stop referring to herself as an environmentalist. “The science across the country, across the world, says that this stuff kills people, kills wildlife,” Mr. Jackson says. “And all that it is, is a giveaway to the large landowners so they can maximize their profits off the lives of the people in Maine and the wildlife in Maine.” Senator Jackson’s words are stern yet factual. Glyphosate has been identified by the World Health Organization as a probable human carcinogen. Monsanto, now owned by Bayer, has been the subject […]

(Beyond Pesticides, June 28, 2021) The endocrine disrupting herbicide propazine (in the triazine family of frog-deforming endocrine disruptors) is set for cancellation by the U.S. Environmental Protection Agency (EPA). The move would eliminate use of the hazardous herbicide by the end of 2022. However, all pesticides in the triazine class, including atrazine and simazine, have similar properties and should be eliminated from use. Tell EPA to finish the job by banning all triazines. In November 2020, Beyond Pesticides and allied environmental groups launched a lawsuit against EPA for its intent to reregister the triazine family of chemicals. The agency’s interim approval of the herbicides, conducted under the Trump administration, eliminates important safeguards for children’s health and a monitoring programs intended to protect groundwater from contamination. As is typical with EPA, the agency merely proposed minor label changes in attempts to mitigate risks identified in its registration review. According to a release from EPA, it made the decision not out of concerns relating to human health and environmental protection, but in order to provide “regulatory certainty” for farmers and local officials. In March 2021, the Biden administration requested a stay on the atrazine lawsuit brought by environmental groups, as it indicated […]

(Beyond Pesticides, June 15, 2021) The endocrine disrupting herbicide propazine (in the triazine family of frog-deforming endocrine disruptors) is set for cancellation by the U.S. Environmental Protection Agency (EPA), according to a Federal Register notice published last week. The move would eliminate use of the hazardous herbicide by the end of 2022. While health and environmental advocates are pleased with the agency’s move, they say it is critical that all pesticides in the triazine class, including atrazine and simazine, also be eliminated from use. In November 2020, Beyond Pesticides and allied environmental groups launched a lawsuit against EPA for its intent to reregister the triazine family of chemicals.

(Beyond Pesticides, June 14, 2021) Beyond Pesticides reports regularly on new science showing how pesticides harm human health and ecosystems. This science is not factored into EPA decisions. Tell EPA that cutting-edge science must be considered. More than 50 pesticide active ingredients have been identified as endocrine disruptors that mimic the action of a naturally-produced hormone, such as estrogen or testosterone, thereby setting off similar chemical reactions in the body; block hormone receptors in cells, thereby preventing the action of normal hormones; or affect the synthesis, transport, metabolism and excretion of hormones, thus altering the concentrations of natural hormones. Endocrine disruptors have been linked to attention deficit hyperactivity disorder (ADHD), Parkinson’s and Alzheimer’s diseases, diabetes, cardiovascular disease, obesity, early puberty, infertility and other reproductive disorders, childhood and adult cancers, and other metabolic disorders. Similar effects are found in other species. In spite of legal requirements and the flood of research, EPA issues Proposed Interim Decisions (PIDs) on pesticide registrations making no human health or environmental safety findings associated with the potential for endocrine disruption, or identifying additional data needs to satisfy Endocrine Disruptor Screening Program requirements in the PIDs. EPA cannot make findings of no unreasonable adverse effects without findings […]

(Beyond Pesticides, June 10, 2021) Exposure to toxic chemicals decreases egg count and increases infertility risk among women, according to a study published in Environment International. Since 2014, U.S. fertility rates have been decreasing, with many attributing the decline to older age pregnancies. However, several findings demonstrate that exposure to environmental pollutants, like persistent organic pollutants (POPs) from the industrial and agriculture industry, contributes to a decline in fertility rates. Scientists and health officials already associate exposure to POPs, like pesticides, with adverse impacts on male fertility, including reduced sperm count, quality, and abnormal sperm development. Therefore, it is essential to understand how exposure to toxic chemicals in the environment affects reproductive success, especially among women who can transfer contaminants to the fetus via the umbilical cord. The researchers note that these findings should urge government and health officials to reexamine chemical safety concerning reproductive health, and “strongly encourage [them] to study mechanisms behind POP-associated infertility in women in more detail.” Researchers examined ovarian egg reserve size in pregnant women directly by examining the density of follicles and immature eggs in ovarian tissue and indirectly via serum anti-Müllerian hormone (AMH). Using AMH serum samples, researchers assessed concentration levels of 31 POPs: nine organochlorine pesticides (OCPs), ten polychlorinated […]

(Beyond Pesticides, June 8, 2021) Biosolid-based fertilizer products like Milorganite, often sold to consumers as “organic,” are contaminated with dangerous PFAS chemicals, according to a study published by Sierra Club and Ecology Center. Biosolids, also known as sewage sludge, have been found in the past to contain residues of hazardous pesticides, heavy metals, antibiotics and other pharmaceuticals, personal care products, and a range of other toxicants. While the latest news may not be surprising for careful shoppers who have long avoided biosolid fertilizers, none of these risks are relayed to consumers on fertilizer packages. With fertilizer regulations failing the American consumer, it becomes more important than ever to seek out certified organic fertilizer products. Sierra Club and Ecology Center looked at nine fertilizer products, each produced from the sewage sludge of a particular American city. For instance, Milorganite, perhaps the most well-known biosolid sludge fertilizer, is derived from the Milwaukee, Wisconsin sewage treatment system. Other products were derived from locations including Sacramento, CA (Synagro); Tacoma, WA (TAGRO); Madison, GA (Pro Care); Las Vegas, NV (Ecoscraps); Eau Claire, WI (Menards Premium Natural Fertilizer); Jacksonville, FL (Greenedge); North Andover, MA (Earthlife); and Washington, DC (Cured Bloom). As the report notes, many of […]

(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 25, 2021) High levels of glyphosate in urine later in a pregnancy is significantly associated with preterm birth, according to recent research conducted by scientists at the University of Michigan. While awareness of the strong connection between glyphosate and certain cancers is growing among the public, the chemical’s link to adverse pregnancy outcomes is beginning to receive more attention. “Since most people are exposed to some level of glyphosate and may not even know it, if our results reflect true associations, then the public health implications could be enormous,” said senior author John Meeker, ScD, professor at the University of Michigan School of Public Health. This latest study is part of a cohort dubbed PROTECT (Puerto Rico Testsite for Exploring Contamination Threats), focused on investigating environmental exposures leading to preterm birth in Puerto Rico. Previous research indicates that Puerto Rico has some of the highest rates of preterm births in the United States, roughly matching Mississippi. With America’s abysmal track record for maternal care, preterm birth rates in these locations also represent the highest in the world. In order to determine the association between glyphosate use and preterm pregnancy, pregnant women between the ages of 18 to […]
