Beyond Pesticides (October 17, 2024) On September 30, 2024, the U.S. Environmental Protection Agency (EPA) opened a public comment period about production of specific per- and polyfluoroalkyl substances (PFAS, also known as âforever chemicalsâ)âincluding perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA). EPA is collecting information on the fluorination process of high-density polyethylene (HDPE) and other plastic containers to inform possible regulatory action under the Toxic Substances Control Act (TSCA). The deadline for submitting comments is November 29, 2024. PFOA and twelve other PFAS compounds are created during the fluorination of HDPE plastic containers by Inhance Technologies, LLC, the only U.S. company manufacturing containers using this fluorination technique (see here). Studies by EPA, independent researchers, and the company itself demonstrate that PFAS leaches from container walls into contents, exposing millions to these toxic chemicals without their knowledge. EPA notes, âLong-chain PFAS like PFOA, PFNA, and PFDA build up in our bodies and the environment over time. Even small amounts can significantly contribute to peopleâs long-term exposure and health risk for cancers, impacts to the liver and heart, and immune and developmental damage to infants and children.â The adverse effects of PFAS exposure are linked to serious health issues, […]

(Beyond Pesticides, October 2, 2024) A comprehensive literature review in Ecotoxicology and Environmental Safety links a heightened risk of spontaneous abortion (SAB) with pesticide exposure. âThe strengths of our study include being the first systematic review and meta-analysis to explore the association between exposure to pesticides and the risk of SAB,â the authors say. This novel approach includes analyzing 18 studies, totaling 439,097 pregnant participants, that allows the researchers to highlight an important public health issue and raise concerns for maternal contact with the harmful chemicals in pesticide products. SAB, also known as spontaneous miscarriage, is defined as the loss of pregnancy occurring prior to 20 weeks of gestation. âIt has been observed that approximately 10â15% of pregnancies end up terminating spontaneously,â the researchers report. According to the authors, these negative birth outcomes can be attributed to many factors such as advanced maternal age, anatomical, immunological, and endocrinological disorders, infections, tobacco use, alcohol intake, abnormalities of the placenta, and exposure to heavy metals, radiation, and pesticides. To connect SAB specifically to pesticide exposure in mothers, a literature search was conducted for peer-reviewed studies that include pregnant study participants, ages 16 and above, who report âexposure to one or more pesticides […]

(Beyond Pesticides, August 8, 2024) With the use of its emergency authorityânot used in nearly 40 years, the U.S. Environmental Protection Agency (EPA) on August 7 banned a pesticide (the weed killer Dacthal or DCPAâdimethyl tetrachloroterephthalate) under the âimminent hazardâ clause of the federal pesticide law. At the same time, the agency is exercising its authority to prohibit the continued use of Dacthalâs existing stocks, a provision that EPA rarely uses. EPA identified serious concerns about fetal hormone disruption and resulting âlow birth weight and irreversible and life-long impacts to children [impaired brain development, decreased IQ, and impaired motor skills] exposed in-uteroâ and finds that there are no âpracticable mitigation measuresâ to protect against these hazards. The last time EPA issued an emergency action like this was in 1979 when the agency acknowledged miscarriages associated with the forestry use of the herbicide 2,4,5-Tâone-half of the chemical weed killer Agent Orange, sprayed over people to defoliate the landscape of Vietnam in the war thereâwith the most potent form of dioxin, TCDD (2,3,7,8-Tetrachlorodibenzo-p-dioxin). While EPA has been congratulated for using its emergency authority, which it is obviously reluctant to use, and health and environmental activists say could be used broadly, the timeline […]

(Beyond Pesticides, June 27, 2024) Earlier this month, Public Employees for Environmental Responsibility (PEER) filed a lawsuit against the U.S. Environmental Protection Agency (EPA) on behalf of a group of ranchers and farmers in Texas harmed by biosolids contaminated with per- and polyfluoroalkyl substances (PFAS). The plaintiffs charge that their health and livelihoods were severely damaged due to contaminated biosolids leaching from neighboring properties onto their land. Despite EPAâs responsibility under the Clean Water Act (Section 405(d) and 40 CFR Part 503) to identify toxic pollutants in biosolids and regulate them to protect human health and the environment, the agency has not effectively addressed the dangers posed by PFAS in biosolid fertilizers. EPAâs failure has dramatic impacts on farmers as well as the public, who are eating or drinking PFAS-contaminated crops, dairy milk, beef, or other meat products. The shortcomings of federal regulations underscore the urgent need for a shift in how federal and state agencies approach these issues, prioritizing precaution to prevent future harm. The persistence of these legacy or “forever” chemicals in the environment illustrates the severe consequences of a historically lax regulatory framework in the U.S. The National Association of State Departments of Agriculture (NASDA) has identified […]

(Beyond Pesticides, June 4, 2024) A study published in the most recent edition of the journal Ecotoxicology and Environmental Safety documents for the first time the presence of the herbicide glyphosate in human sperm. The study looked at 128 French men with an average age of 36 years who tested positive for glyphosate in their blood. Seventy-three out of the 128 men were found to also have glyphosate in their seminal plasma. Not only that, the amount of glyphosate in seminal plasma was nearly four times higher than what was detected in the blood.  Methods The study involved a population of 128 infertile French men from whom seminal and blood plasma samples were collected. The study was conducted at the “Pole SantĂŠ LĂŠonard de Vinci” medical center, located centrally near Tours, France. This region is recognized for its urban characteristics as well as being a major agricultural hub, particularly for grain and wine production. The study authors note, âThis area reflects the common herbicide exposure in Franceâ and the district ranks third highest in terms of pesticide purchases. While additional qualitative data was collected, only 47 of 128 participants fully completed a questionnaire about their profession, diet (organic or […]

(Beyond Pesticides, June 14, 2023) A study published in Scientific Reports finds a link between pesticide exposure and recurrent pregnancy loss (RPL) through oxidative stress and apoptosis (cell death) in the placenta. Recurrent pregnancy loss (RPL) is the loss of three or more successive pregnancies before 24 weeks of gestation (pregnancy) and signifies an underlying reproductive health issue. The study highlights that pesticides’ endocrine-disrupting (ED) properties can have varying adverse impacts on biological processes, including immunology, metabolism, and reproduction. Pregnant women experience frequent exposure to environmental pollutants that pose serious health risks to both mother and newborn. Many known pollutants (e.g., heavy metals, polychlorinated biphenyl, and pesticides) are chemicals with ED properties that can move from the mother to the developing fetus at higher exposure rates. Additionally, pregnant women are experiencing exposure to an increasing number of dangerous industrial chemicals. With a range of scientific data highlighting chemical exposures during pregnancy as a critical window of vulnerability, public awareness of these threats is growing. The study notes, “They are associated with an increasing placental OS [oxidative stress] and placental apoptosis. Specific measures should be taken to decrease maternal exposure to these pollutants’ sources, especially in underdeveloped and developing countries.” For RPL, the research investigated pesticide components in blood plasma, […]

(Beyond Pesticides, December 6, 2018) A recent analysis of annual drinking water quality reports has revealed that many community drinking water systems in the Midwest have seasonal exceedances of the allowable limit for the herbicide atrazine. Atrazine, linked to endocrine disruption, neuropathy, and cancer, is the second most widely used pesticide in corn growing areas, with over 73 million pounds applied to agricultural fields each year.  A 2009 study by Paul Winchester, MD, professor of clinical pediatrics at Indiana University School of Medicine and a neonatologist at St. Francis Hospital in Indianapolis, linked birth defects to time of conception, with the greatest impact on children conceived when concentrations of atrazine and other pesticides are highest in the local drinking water. (See Reproductive Effects Peak with Pesticide Exposure.) During peak use, atrazine levels in drinking water have been recorded at three to seven times above the legal limit. In addition to the well documented impact on the environment, recent  studies have linked prolonged pesticide exposure to not only shortened gestation and preterm birth for women, but also neurodevelopment delays in children. Ultimately, these unreported seasonal peaks may result in persistent adverse health impacts in impacted communities. The Safe Drinking Water Act (SDWA), enacted in 1974, […]

(Beyond Pesticides, December 6, 2010) A new study finds that exposure to dioxin in the womb can affect female reproduction for generations, reducing fertility and increasing the chance for premature delivery. Scientists from the Women’s Reproductive Health Research Center at Vanderbilt University School of Medicine examined the effects of a specific variety of dioxin on female mice and found that subsequent generations of the mice exposed to dioxin are at risk. The study, entitled âDevelopmental exposure to TCDD reduces fertility and negatively affects pregnancy outcomes across multiple generations,â was published in the journal Reproductive Toxicology. Dioxin refers to a family of chemicals linked to cancer, endocrine disruption, weakened immune systems and reproductive problems. They are persistent organic pollutants that bioaccumulate in humans and other animals, especially in fatty tissue, meaning that concentrations of dioxin in the body generally increase with age. So, even in very low doses, dioxins can cause health problems. Scientists in this study specifically looked at the variety of dioxin that is considered the most toxic, known as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). TCDD is a well-known contaminant of the herbicide 2,4-D, which was originally a part of the deadly chemical weapon Agent Orange. As such, TCDD is still found […]

(Beyond Pesticides, May 6, 2008) Pregnant veterinarians who have occupational exposures to pesticides, anesthetic gases or radiation may have twice the risk of miscarriage, according to a new study published in the May 2008 issue of the journal Occupational and Environmental Medicine. The study, “Maternal occupational exposures and risk of spontaneous abortion in veterinary practice,” looked at the experiences of 1197 female veterinarians working in clinical practice, who graduated from Australian veterinary schools between 1960 and 2000, responding to a questionnaire-based survey. There was a twofold increase in the risk of miscarriage in women veterinarians who use pesticides at work. The researchers found that there was also a twofold increase for those exposed to anaesthetic gases for more than an hour a week without using equipment to remove the gas from the air, and an 80 percent greater risk of miscarriage in those who performed more than five x-ray examinations per week compared with those who performed five or less. Veterinarians are often unable to leave the room whilst performing an x-ray because they have to hold the animal being x-rayed in order to restrain it. Adeleh Shirangi, Ph.D., author of the research from the Department of Epidemiology and Public […]
